Project Number TBD

Status Planning

Estimated Service Date December 2017 Work Description: Implement Maximo Enhancements to Support Steam Business Processes – Perform enhancements as required by the business areas to support their process for cost effective planning, scheduling and overall asset management. PI Enhancements: Enhance corporate PI displays and the use of plant operational data by implementing new PI software tools to assist in the identification of PI system alarms and station performance issues; implement PI condition based monitoring to allow engineers to monitor critical attributes of equipment condition using the PI data already being gathered; use predictive tools to enhance current maintenance programs; and implement software tools to provide a consistent platform between stations, monitor the health of the steam plant, and increase fuel savings, efficiency, optimization, and performance. Steam Plant Infrastructure Upgrades: The existing data communications local area networks (LAN) supporting our Steam Stations require significant infrastructure upgrades to bring them up to current standards of reliability and performance. Justification: Incorporate several enhancements to the Central Operation Status Reporting System (COSRS) in Maximo to improve ease and quality of data entry. Enhance the flow of work through the system by enforcing rules regarding required and locked fields on the change of incident/event status. Enable users in different security groups to have the ability to modify data when the incident / event is in a specific status. These enhancements are required to keep the application working effectively for the key business users. The primary justification of the project plans are to mitigate the currently elevated risk of extensive communication system outages resulting from the existing condition of the LAN infrastructure – outages that could be extensive in duration due to high MTTR of many components. The secondary justification is to enhance Steam’s communication performance, i.e. Wi-Fi installations, switch upgrades and high speed network access.

Project/Program Title East River SSS – Economizer Replacement

Functional Program Boilers

Project Manager Rich Ferris

Project Engineer Chris Bentley


Project Number 23971-10

Status Planning

Estimated Service Date May 2013

Work Description: The scope of work includes replacing the existing economizers with new, redesigned economizer modules. To address fireside cleanliness, doors were added on both sides of each economizer module which expose the return bends and terminal tubes allowing for thorough cleaning. A vent header above the economizers that extends from each boiler to its drum vent stack on the west wall of the boiler house will be installed. Justification: The five operating package boilers have economizers that are experiencing failures due to fire side and water side corrosion. There is evidence that oxygenated water has pooled in the economizer indicating it was either not drained or allowed to cool. Redesign includes modifying flow piping to provide better draining and upgrading materials that are not as susceptible to oxygen corrosion. Also, there is evidence of external corrosion. During the first half of the economizers’ operating life, little access was provided for adequate fireside cleaning of the oil ash. Together, the waterside and fireside damage has led to 101 failures in the past five years.

Project/Program Title 74th St – Boiler 121 Economizer Replacement


Project Manager Randy Mester

Project Engineer Jim Leary



Status Active


Work Description: The scope of work includes replacing the thirty four upper and lower assemblies of economizer tubes, replacing damaged sections of the forty-two downcomer tubes supporting the economizer replacing the economizer inlet header along with the economizer inlet legs, and installing four access doors opposite the existing doors. Justification: The Boiler 121 economizer consists of assemblies with carbon steel peg fins welded along the straight length of each economizer tube. The residual stresses and cyclic loads applied to the tubing along with a corrosive environment have led to fatigue coupled with preferential corrosion at the toe of peg fin welds. Further, repeated failures are occurring in the four hanger tubes and thirty-eight downcomer tubes. The magnitude of damage became apparent after a series of through wall failures following a change in water chemistry. Therefore, replacement of economizer tubes becomes critical to ensure the reliability of the boiler operation. The current boiler design provides limited accessibility in certain areas. New doors will be installed to aid the ease of maintenance. It is intended that as a result of this project the economizer will be more accessible for inspections, cleaning and repairs.

Project/Program Title 74th St – PB#1 Refurbishment of Convection Pass Outside Wall Tubes






Status Planning


Work Description: The scope of work includes refurbishing the convection pass outside wall tubes and replacing the associated boiler refractory, insulation, lagging, and casing. Justification: The convection pass outside wall tubes were seal welded on both sides of the drums. This restricts the movement of the tubes and does not allow for proper expansion. These tubes have been failing and leaking over the past several years. The failures are being attributed to corrosion fatigue stress cracking and cyclic stresses from the frequent/daily cycling of the unit. Performing the refurbishment at this time would increase the reliability and availability of the unit for continued long-term service.

Project/Program Title 60TH Light Oil Firing






Status In Planning


Work Description: This project will upgrade the existing fuel oil facilities at the 60

th Street Station to allow light oil (kerosene)

firing. It includes upgrading the tanker truck delivery system and installing a light oil supply system consisting of new pumps, strainers, meters, control valves, oil supply and return piping as well as new dual fuel low NOx burners. The fuel oil tank room fire protection will also be upgraded to include new deluge valves and sprinklers to conform to current city and NFPA Codes. Justification: The 60

th Street Steam Station package boilers were originally designed to burn either fuel oil or natural gas.

The station has never operated on heavy fuel oil, but has been capable of light oil burning. This new system will make deliveries and burning more reliable, bring the installation up to current codes and allow for Low NOx operation in compliance with current operating permits and interruptible gas supply contracts.

Project/Program Title 59th Street – Package Boilers Air Heater Upgrade


Project Manager Keith Guberman




Status In Planning


Work Description: Refurbishment of the air heaters on 59th Street’s 117 and 118 requires the replacement of all hot end and cold end baskets, the replacement of all radial and axial seals and the replacement of both hot end and cold end bearings. There is one Air Heater per boiler. Justification: The deterioration of the air heater baskets has exceeded that from which the reasonable performance can be expected. The reduction in performance is evidenced by elevated exit gas temperatures and by visual inspections. The replacement decision is largely based on the age of the equipment and potential performance recovery.

Project/Program Title 60Th St – Air Preheater Upgrade






Status Planning


Work Description: The six air preheaters will be refurbished by replacing all damaged and deteriorated equipment with OEM vendor supplied parts and material. Any hidden damage, i.e. insulation, lagging, piping, etc. will be repaired or replaced as required. Upon completion of the insulation of the baskets and new seals, all OEM specified clearances and tolerances will be set. Justification: Replacement of critical air preheater components is recommended to improve air preheater performance, reliability, and maintain proper exit gas temperatures. Repairs to these components are not practical due to the extent of the deterioration. The payback due increase in efficiency (reduced fuel cost) is about 3.5 years.

Project/Program Title 59th St 115 Generating Bank Replacement






Status In Planning

Estimated In- Service Date December 2016

Work Description: This project will remove and replace rear wall tubes for access, remove and replace 1276 generating bank tubes, remove and replace the generating bank baffles, and repair damaged areas in the drum and drum parts. Justification: For the unit to remain reliable the damaged tubing will need to be replaced. If the tube plugs exceed 14percent total or 30 percent in a 6x5 area, we will not be able to operate this unit without causing harm to other water circuits. Discrepancy: The budgeted dollars are considerably lower than the Order of Magnitude Estimate. Reasoning for Discrepancy: Originally this job was scoped as a partial replacement therefore a budgetary material cost from the OEM was gathered and the installation costs were estimated based on a recent Ravenswood partial generating bank replacement estimate. A detailed of the scope review indicates the entire generating bank will require replacement in order to access all of the damaged tubing. The official Order of Magnitude Estimate for this project was performed based on the new scope and was only recently received for review.

Project/Program Title 74th St – Boiler 122 Water Wall Tieback Upgrade






Status Planning


Work Description: The scope of work is to upgrade the furnace wall support system by adding a new elevation of tie-bars in the burner zone area. Removal and replacement of associated furnace wall brick/tiles, refractory, insulation and casing from the second, third, and fourth floors of the unit. Repair of existing shoe-guides on all four furnace walls. Replace select furnace wall straight tubes that are severely bowed into furnace and cannot be secured to tiebacks or shoe-guides. Justification: A number of waterwall tubes are bowing into the furnace by varying degrees. Out of plane tubes allow hot flue gas to get between the tube wall and the exterior wall enclosure. Once behind the tube wall the flue gas will overheat and destroy the refractory, insulation, casing, (BRILC) and shoe-guides/tie-backs. This will allow overheating of the casing, which can eventually burn through resulting in air in leakage and pose a potential safety hazard to passing station personnel. The issues of the tubes bowing verses the deterioration of the shoe-guides and the BRILC have created a cause and effect relationship that self propagates and exacerbates the problem for one another. Delaying the repair will increase the chances of equipment failure and will affect the reliability and safety of our steam system.

Project/Program Title 74th St HP Boiler Degasser System






Status Planning


Work Description: This project is to install a degassing system to remove dissolved oxygen prior to the deaerators, and to use the deaerators as a direct contact heater. Justification: The Degassing system is a chemical free, deoxygenating system used to produce feedwater with low levels of dissolved oxygen, protecting the boiler from oxygen pitting corrosion. The system uses membrane contactors to remove the dissolved oxygen from the water. The membrane contactors use a combination of vacuum and inert gas to create the driving force to remove the DO and CO2 from the feedwater. The degassing system will eliminate the need for the deaerators to vent steam to atmosphere to remove dissolved oxygen from the feedwater.

Project/Program Title 74th St – Package Boiler Demineralization Tie






Status Active

Estimated Service Date June 2013 Work Description: This project is to provide a source of demineralized water to the package boilers (PB) for blending purposes in order to achieve a quality similar to Catskill water and to ensure steam meets PSC conductivity requirements, even when operating on Croton water. The main water source will be to transfer demin water from the HP Boiler treated water tanks to the Package Boilers (PB) treated water tank. The new system will include PB treated water transfer pumps, piping, flow elements, control valves, instruments and controls system, power supply and civil work. The demin water will be blended with the existing PB softened water during normal operation and will be able to supply enough water for the typical station load. Demin Trailers will supply supplemental demin water for the PB system during the peak load season as backup (approximately 2-3 weeks/year). Justification: Updated continuous chemical monitoring has shown that the package boilers are currently unable to produce steam with conductivity below the PSC limit for the full load range of the units when on Croton water supply to the softening treatment system. The high conductivity in the steam results from the increased carbonate levels in the Croton supply as compared to the Catskill water supply. This was demonstrated in the Fall of 2008 when the NYCDEP put the Croton supply system into service for a short period of time. At that time, demineralization trailers were brought in to provide additional make-up water to help meet the steam purity limits for conductivity. When the Croton system is put into service in 2013, we will require a permanent supply of demineralized water for the package boilers to ensure that steam purity limits are met.

Project/Program Title 74th St – HP Condensate Recovery





Project Number TBD

Status Planning


Work Description: This project will consist of the installation of a recovery system that will collect the waste condensate energy and transfer the energy to the deaerator makeup water. This will require installation of a flash tank, heat exchangers, auto controls, and piping. The installation of this energy recovery system reduces the steam operating cost for the deaerators; improves the oxygen removal of the deaerators and recovers the cooled condensate into the Raw Water Tank. Justification: Presently the 74th St Station diverts their high pressure and low-pressure condensate into the Treated Water Tanks, and on occasions cause the temperature to rise above 120°F. Under certain conditions, the temperature rises above 175°F. This high temperature in the past has the potential to damage the lining of the Treated Water Tanks. The implementation of this project will remove the condensate from the Treated Water Tanks and the Raw Water Tank and eliminate the detrimental effect on the tank lining, improve the oxygen removal within the deaerators, reduce the steam usage of the deaerators and insures that the condensate is processed in accordance with the ASME code.

Work Description: This project is to upgrade the vent piping shared by Surge Tanks Nos. 3 and 4 at the 59th Street Steam Generating Station. The work will entail the installation of approximately 70’ of new 12” pipe to replace an existing 6” pipe section of the vent line. Justification: Surge Tanks Nos. 3 and 4 provide a means to recover multiple sources of condensate discharged from the Annex main steam system, Auxiliary steam system, and several Deaerator No. 5 drain lines. The Surge Tanks are vented through a common 12” header. The line includes a long section of 6” pipe that is not adequately sized to protect the tanks against the pressure buildup caused by the high temperature return lines. As a result, through-wall vapor leaks have developed at two points along the vent piping run. The vessels were initially designed and fabricated as atmospheric storage tanks and this development of pressure can ultimately lead to catastrophic failure.

The existing air dryer will be replaced with two new desiccant type air dryers. The existing air receiver will be replaced with a new air receiver. Flow and pressure transmitters and gauges will be installed. New cables and conduits will be installed for the power supply to air compressors, dryers, and associated system components. These air compressors and dryers will be connected to the DCS via mod bus network. A moat will be built around the compressors, dryers and receiver to protect equipment from category 1 flood level. Justification: The existing air compressors, air receiver and dryer were installed in 1990. They have completed their average useful life and have developed extensive maintenance issues and are due for retirement now. The air receiver is aged and rusted externally. The dryer cannot maintain the required dew point and requires frequent maintenance. Air compressors and associated equipment are installed below category 1 flood level.

Project/Program Title East River – Unit 1/2 CTG Filtration Upgrade

Priority Number Mechanical Equipment Replacement


Project Engineer Daniel Tsang



Status Planning

Estimated In-Service Date March 2014 Work Description: The project is to upgrade the existing Unit 1/2 Combustion Gas Turbine air inlet filtration systems. At minimum, this will include a retrofit of new cartridge filters. Additional upgrades may also include the installation of coalescing filters to remove small liquid droplets and inlet dampers to control the draft of air flowing into the turbine during shutdown. The optimal filtration system should eliminate ingress of corrosive elements and provide high filtration efficiency without restricting adequate mass flow to the gas turbine over the expected life of the cartridge filters. Justification: The East River Steam Generating Station houses two (2) Combustion Turbine Generator (CTG) systems (Units 1 and 2), each consisting of a General Electric MS7001FA+e gas turbine for the production of municipal steam and electrical energy. The gas turbines, due to their inherent designs and amount of air consumed, are sensitive to air quality. Both CTG systems have an inlet air filtration system applied that provides protection against erosion, fouling, and corrosion. The Unit 1/2 filter houses each consist of intake weather hoods with moisture separators and self-cleaning pulse cartridge filters. The upgraded filtration system will better reduce compressor fouling, maximizing compressor efficiency and potentially reducing water wash frequency. This would yield cost savings resulting from reduced maintenance and better gas turbine performance.

Tank 4 is degraded to a point where the side walls are leaking through. The roof of Tank 4 is also leaking, allowing water vapor to escape and damage the beams and the floor above. Justification: Replacement of Tank 4 is required because this tank is leaking and its general condition is very poor. Repairing the leaks on Tank 4 is not practical. Replacement with Stainless steel similar to Surge Tank 3 will eliminate future corrosion.

Status Planning


Work Description: In order to provide demineralized water to the East River South Steam Station and satisfy steam purity requirements, a stainless steel transfer line including valving shall be run from the existing units 1/2 demineralized water tanks. This line will run through the connection bridge, bypass the existing softening system, and discharge into the treated water tank. All piping and fittings within the South Steam Station prior to the boiler inlet will be converted to stainless steel. An additional chemical feed system including re-alkalization and phosphate feed skids will be required to provide high energy boiler feed piping protection and internal boiler chemical treatment. Justification: Updated continuous chemical monitoring has shown that the package boilers are currently unable to produce steam with conductivity levels below the PSC limit for the full load range of the units when on Croton water supply to the softening treatment system. The high conductivity in the steam is a result of the increased carbonate levels in the Croton water supply as compared to the Catskill water supply. When the Croton system is put back into service in 2012, we will require a permanent supply of demineralized water for the package boilers to ensure that steam purity limits are met. Demineralized water is aggressive so treated water piping in the package boiler system will need to be changed to stainless steel for corrosion protection. Re-alkalization and phosphate chemical feed systems will be installed to provide high energy boiler feed piping protection and internal boiler chemical treatment. The blowdown valves will be replaced to accommodate the much lower continuous blowdown flows required for demineralized water operation (on the order of 1-2percent).

Project Number TBD

Status Planning

Estimated Service Date June 2016

Work Description:

This project will consist of replacing the HP Fuel Oil Heat Exchangers after 15 years of operation. The criteria for fuel oil heater replacement is 10percent tube plugging. Review of the data show the following general observations:

Difficulty in tube cleaning prior to testing appears to have occurred at all Stations.

The frequency of testing ranged from 5-15 years.

The damage mechanisms causing wall loss occur on the outside surface: pitting corrosion, localized erosion at tube supports and erosion from tube to tube vibration.

Cleaning the #6 fuel oil sludge/reside from the inside surface of the tubes in the fuel oil heaters is necessary to facilitate the eddy current testing of the tubes. The latter test is needed to assess the condition and remaining life of the tubes.

Review of the Station data indicates that the cleaning of the fuel oil heaters has always been a laborious process with varying degrees of success with extensive environmental implications resulting from the cleaning.

Justification:

Implementation of this program will minimize the potential a SPDES violation from an oil spill resulting from a tube leak and or a mishap during the cleaning of the heat exchanger.

Project/Program Title ER 1&2 - HRSG Drain Header Modification





Project Number TBD

Status In Planning


Work Description: This project will consist of modifying the existing 12” superheater manifold located below the HRSG casing. This is to insure that condensate cannot collect in the superheater inlet manifold prior to GT ignition, particularly when the GT is cranking and un fired. The existing superheater drain system design (1”, and 2” pipe and single drain point from the nominally horizontal superheater inlet manifold) increases the risk that un-drained condensate will migrate into the superheater and cause thermal fatigue damage. In order to eliminate this condition two (2) more additional drain pots with 2” drains lines shall be installed on the 12” superheater manifold. The three (3) 2” drain lines (two (2) new drain pots and the existing drain pot) from the drain pots shall be connected into a 3” drain pipe. Justification: Water from condensation in pipes and superheater tubes and /or leaking attemperators cannot be expected to completely drain from the 12” superheater manifold located below the HRSG casing. Nominally, level pipes in HRSGs have been noted to accumulate water in pools due to permanent and/or transient low points and/or tilting when sufficient sized drain points are not located at all permanent transient low points. If pooling occurs in the superheater inlet manifold because one, or more permanent or transient low points occurs not at the single existing drain point, such trapped water remains in the superheater inlet manifold even after water ceases running from the single drain point and is carried up superheater tubes when significant steam flow is reached.

There are two Fisher 16 X 10 Globe Style EWND Whisper Trim Valves that have been in service since the late 1980s. Each valve has the ability to maintain full plant loading of 760 Klbs/Hr. Fisher Service has inspected these valves and recommends new trim or replacement. These valves have reached the limit of their useful life and it is more cost effective to replace the entire valve than replace the trim. Justification: These valves have been binding internally causing loss of backpressure control for the PB Plant. The short term performance of the current valves is a significant O&M contributor, and replacement will reduce the repetitive O&M expenditure. Valve replacement will also provide a higher level of reliability with respect to valve performance.

Project/Program Title 74th Package Boilers Raw Water Tank Relining






Status In Planning


Work Description: The existing lining inside the Raw Water Tank will be cleaned and then sandblasted. The tank will then be relined and tested to withstand normal operating temperatures of the raw water system above 100°F. This new relined area will include the interior of the walls and the floor of the tank as well. The new lining will then be required to cure and be tested to ensure its proper adhesion. Scaffolding will be required to complete the work necessary for the tank relining. Justification: In 2007 an inspection was completed and the results of which recommended relining the tank within 3-5 years. It has since been determined that the tank liner has reached the end of its lifespan and currently is in poor condition in various locations. The new liner will be acceptable above 100 F to insure that inadvertent hot water introduction does not adversely affect the liner.

Project/Program Title ERSSS – Replace DA2 level and Pressure Control Valves






Status In Planning


Work Description: Install new level and pressure control valves and a Recirculation Loop Consisting of a Recirculation Pump, Relief Valve and Piping from the farthest point on the Feedwater Line to the Deaerator Discharge .The Ovation System can be used to control the operation of the Recirculation Pump based on the oxygen content of the water. The Recirculation Pump should be sized for 30percent of the Deaerator capacity. Justification: The deaerator will function as an open feedwater heater during normal operation after the future Degassing system is installed. In the event the Degassing system is removed from service the deaerator’s original capacity will have to be restored to remove any dissolve oxygen in the feedwater. In order to enable this dual operational configuration the modification listed in the work description needs to be complete. Any high dissolve oxygen levels will result in corrosion to the boiler water system, reducing equipment reliability and efficiency, SSO derate, and safety. Estimated Completion Date: December 2015

Project/Program Title 59th Pier 98 Foam Monitors 23422-09






Status Planning


Work Description: All six foam monitors are operational but only spray in the direction they are pointed as the mechanism which allows them to oscillate automatically for complete coverage of the barges does not function. The foam monitors that provide coverage for the oil barges which dock at the pier are in a degraded condition and do not oscillate automatically. The scope of work involves replacement of the foam nozzles and installation of new supports to facilitate these new nozzles. A Water Powered Oscillating Monitors shall be used; one which is designed to automatically discharge over a specific design area upon system activation. The nozzles should be suitable for use in high risk areas such as tank farm facilities, refineries and chemical plants.

Justification: Per NFPA and NYC Fire Codes, oscillating monitors shall be fully functional and perform as expected per design. Therefore it is recommended that the oscillating foam nozzles be replaced. Estimated Service Date: December 2015 Status: In Planning Current Working Estimate (if applicable): Funding ($000):

Project/Program Title 74th – Trolley Beam – Access to Basement





Project Number TBD

Status Planning


Work Description: This project consists of installing a trolley beam above the door and stairs between the gas turbine area and the package boiler pump room. The implementation will require a trolley beam to extend far enough into the pump room so that equipment can be landed at the foot of the stairs without blocking access to the stairs. On the other side, the beam should extend far enough into the gas turbine area so that access through the door is not blocked. There is a corrugated metal wall separating the gas turbine area and the pump room. This wall is not a fire rated wall. Justification: The pumps and motors in the Package Boiler Pump Room need to be removed in a safe manner on a regular basis to perform preventive maintenance. The preventive maintenance is performed off site. Removal requires that the equipment be lifted to an elevation six feet up and through the door into the gas turbine area. Currently temporary rigging has to be installed on the floor above to lift the equipment. The heaviest equipment, which is regularly moved through the door, is a motor, which weighs 4500 lbs.

Project/Program Title 74th Fuel Oil Tank Fire Protection Sprinkler Upgrade


Project Manager Richard Johns




Status In Planning


Work Description: 74th Street Station's fuel oil storage tanks (five 20,000 gal kerosene and four 20,000 gal No. 6 oil) are protected by an obsolete deluge type sprinkler system. The original design installation included sprinkler heads with temperature spray heads. Although the systems are in compliance with NYC fire Codes and NFPA Sprinkler Codes there is a potential for link wetting or cold soldering of the intermediate heads causing certain areas not to get water spray coverage if the system eventually operated. Also just replacing the heads to open spray heads with the existing detection system can cause flooding. Therefore the deluge system (including the addition of open spray heads, detection system, fire alarm panel and deluge valve) requires to be upgraded. Justification: NFPA 13 and NYC Fire Codes requires suppression system to be fully functional and able to be inspected and successfully maintained. Solely adding new open heads to an existing system with a degraded detection system will cause a risk of flooding due to spurious inadvertent activation of the existing outdated system. Thus entire deluge system (except for piping) requires upgrading. Estimated Service Date: December 2015 Status: In Planning Current Working Estimate (if applicable): Funding ($000):

Project/Program Title 74th BFP Warmup Recirculation Recovery





Project Number TBD

Status In Planning


Work Description: This project will consist of installation of a 1”flow line to continuously warm the boiler feed pumps when out of service. This will require the routing of a 1” flow line from the discharge line after the motor operated valve to upstream of the discharge check valve (connect to the gage line). All boiler feed pumps need to have this warming modification installed. Operations take 4 1/2 hours to warm up a pump and so they keep extra pumps running in case one trips out of service. This wastes horsepower and increases pump wear. Justification: Presently Operations takes 4 1/2 hours to warm up a pump and so they keep extra pumps running in case one trips out of service. This wastes horsepower and increases pump wear. The lack of pre-warming of feed pumps can also cause severe damage if pumps are required without warm-up under emergency conditions The implementation of this project will reduce operating and maintenance cost.

Project/Program Title ER – HRSG 10/20 ECONOMIZER REPLACEMENT






Status In Planning


Work Description: This project involves the removal and replacement of the fourteen economizer harps of East River Units 10 and 20. This replacement is expected to be done by modular design such that all of the existing economizer harps and headers will be removed and replaced. The new harps will be considered a like in-kind type replacement, but includes header and tubing material upgrades, from carbon steel to 1.25 percent Cr - 0.5 percent Mo, along with alignment, support and flow distribution modifications. This also project entails removing and replacing part of the power house roof, portions of inlet ductwork and portions of the HRSG enclosure. Justification: The economizer of ER 10 and 20 is counter current cross flow design built in two trains of seven carbon steel harps. This design evidenced by inspection and modeling, induces turbulent flow characteristics near the ends of each header due high fluid velocity and flow disruptions. The turbulence, water chemistry requirements, water temperature and the lack of chromium in the carbon steel has led to single phase and dual phase flow accelerated corrosion (FAC) damage. The worst of these areas failed leading to the global discovery of FAC and the necessary replacement of the upper headers and top eighteen inches of Harp 12 and Harp 13 during the Spring of 2009. Changes in water chemistry have also been enacted, but it is expected that corrosion damage will continue in other headers and tubes at a rate of 3-4 mils/yr making replacement necessary by 2017.

Modify piping to provide a common supply header with one penetration per tank; modify vent lines to run common. Install tank instrumentation and controls and signal forwarding to control room. Inspect, repair and ensure power supply to existing condensate recovery pumps and associated controls. Justification: The overall integrity of ST 7 & 8 was identified as “satisfactory to poor”. Tanks ST 7 & 8 collect non-treated water and condensate for re-circulation to the Raw Water Tank; if not collected, this water has to be sent to the discharged tunnel, increasing the fresh water usage of the Station.

Coat all steel columns, girders and beams not abutting the moat wall, but within 10-feet of the moat with a 2-hour, UL1709, approved fireproofing material. The bottom 8-feet of all steel columns that butt up against the moat wall will be encased in 2-hour fire rated concrete. The remainder of the steel columns, girders and beams within a 10-foot distance of the moat will be coated with a 2-hour, UL1709, approved fireproofing material (i.e. Monokote Type PK-140). Justification: In the event of a catastrophic tank failure, kerosene and/or #6 fuel oil will spill into their combined secondary containment moat. If the contained product should ignite it can cause the building structure located directly in the moat and within 10-feet of the moat to fail. The intent of this project is to install a protective coating on the steel columns, beams and girders inside the secondary containment moat area and within 10 ft. of its boundaries. The coating shall have, at a minimum, a 2-hr rating per UL 1709 (high-intensity hydrocarbon fire).

Project/Program Title 74th PRS9 Desuperheater Thermal Sleeve






Status In Planning

Estimated Service Date December 2016 Work Description: The scope of work below is being recommended for the PRS #9 desuperheating system problem.

1. Retire and remove the interposing Yarway Templows (TCV-0921C & TCV-0922B) which was the suspect of causing the localized piping high thermal stresses.

2. Install a new atomizer type desuperheater (CCI type DAM or equal) to improve the vaporization process and supplied with an external spray control valve to provide a better range ability.

3. The DAM desuperheater assembly is comprised of approximately4 feet of alloy steel spool pipe with spring loaded spray nozzles mounted on the pipe periphery. A liner is provided and installed in the DAM spool pipe to protect the pipe from thermal shock and to increase the steam velocity on low flows to improve the evaporation rate.

4. Modify the desuperheating water line to accommodate the installation of the new spray water control valve.

5. Provide and install a new controller for the new desuperheater along with the control logic. Justification: The direct contact of the sprayed water on the pipe should be avoided since this condition was the suspect of leading to high thermal stresses particularly during startup and changing loads. The proposed atomizer/desuperheater will not only improve the vaporization process but also provide a physical barrier between the spray water and the pipe wall.

Project/Program Title 74th Kerosene Tank Piping Relocation For Tank Isolation





Project Number TBD

Status In Planning


Work Description: This project will consist of installing isolation valves on the six (6) kerosene storage tanks in order to meet all code requirements. The implementation of this project will involve the dismantling of the current set-up. In its place, two valves shall be installed to meet code and safety requirements. These valves will be installed in series to provide a double-isolation valve system. One of the valves will be a new automatic-closing heat-actuated valve (fusible link valve) with manual override, as required by code. The other valve will be a manual shut-off valve. By removing the existing setup, there is room to install the new valves with minor piping modifications. The new valve set-up will connect the tank to the existing header on the discharge side of the Kerosene Tank. This change should be incorporated at each of the six kerosene storage tanks. Operators must have the capability to isolate the system in case of an emergency, per NFPA 30. Justification: The Kerosene Tanks at 74th St currently have two parallel valves on the discharge side of the tank. One is a fusible link valve and one is a shut-off valve. With these valves in parallel, the tank cannot be properly isolated from the system. During the last tank inspection, a rigorous procedure was used to ensure that there was constant monitoring during the inspection. This wasted time and resources. The current setup does not meet OSHA requirements or the Con Edison White Book requirements for double valve isolation and leaves employees in a potentially hazardous situation. It also doesn’t meet NFPA 30 requirements. Estimated Service Date: December 2016 Status: In Planning Current Working Estimate (if applicable): Funding ($000): Forecast 2013

The Boiler Feed Pumps then pressurizes the water to approximately 850-psig for supplying to two Boiler Drums through a 6-inch main piping. The original piping has been in service for over 50 years. Justification: The layers of oxide and other deposits on the inside of the deteriorated piping break off and cause equipment degradation and malfunction within the feedwater circuit. In particular the debris is detrimental to the impulse lines, and might have contributed to the frequent boiler trips. The boiler feed water piping is vital as it supplies feedwater to the two Annex Boilers for steam production for internal use and NYC steam sendout.

Estimated Service Date December 2016 Work Description: This project is directed at complying with Con Edison Engineering Specification El-2016 [Rev. 1, June 1994] and Illumination Engineering Society of North America [IESNA] standards for the sufficient illumination of the turbine room floor. The project also provides for safe replacement and troubleshooting access by maintenance personnel to the lighting fixtures. In essence, occupational and safety hazards brought about by poor visibility, non-uniform illumination, and dangerous access to the fixtures in the area are corrected. Under this project, new, highly efficient, Metal Halide High Bay Lighting System will be installed in safely accessible cantilevered and hinged fixtures mounted on columns at E.L. 74th’-0” gallery railing level throughout the length of the approximately 800’ long by 78’ wide by 77’ ceiling height turbine hall. The gallery with its railing will provide the platform for easy access to the fixtures while safety in cleaning, bulb replacement, and repair will be realized through the hinge in their support base. The existing lighting fixtures supported from the roof truss structure at 77’ above the turbine room working floor and their associated wiring and conduits will be removed. The existing lighting fixtures use eight (8) lighting panels partially which consists of (36)-20A circuits, (8)-35A circuits, and an unnamed panel without a circuit schedule. New wiring and conduits will be provided to the new lighting fixtures. The new highly efficient lighting fixtures will utilize two lighting panels partially consisting of (8)-20A circuits and (14)-35A circuits. Justification: The existing 1000W High Pressure Sodium Lighting system is 30 years old, very inefficient and in a very poor state of maintenance due to the mounting locations (i.e. from the room truss structure at 77’ above the working floor) and lack of access. The lighting produced is inadequate in terms of quantity, distribution and color. These poor lighting conditions pose additional operational and occupational safety hazards for turbine room personnel and equipment. Existing light meter readings were taken and were recorded at less than half the IES recommended levels for this application. Components of the existing system were also missing posing a safety hazard. Estimated Completion Date: December 2016 Status: In Planning Current Working Estimate (if applicable): N/A Funding ($000):

Work Description: This project will upgrade the current Mark V control system to the Mark VIe. The upgrade provided by GE will replace the existing “196” processors with new 667 MHz PowerPC processors. The internal ARCNET communication system will be replaced with 100MB Ethernet. These changes will not affect the current I/O and will not require any changes to the existing Packaged Electrical and Electronic Control Compartment (PEECC). The network infrastructure will be upgrade to remove a single point failure and allow for network redundancy. Network infrastructure will require running new conduit and fiber optic cable between each turbine control room (LEECC) and the terminal board room. Justification: An End-Of-Life (EOL) notice was distributed by GE in 2004, which gives the system supportability until 2014. Past that, no further Technical Assistants (TAs) will be trained on the Mark V, and parts will no longer be supported. With the current configuration, the only option will be to self maintain the Mark V with existing spare parts and suppliers, and develop and secure long-term network of TAs to support the station for various troubleshooting issues. Also, ARCNET communications protocol no longer meets IEEE standards and will require conversion to 100MB Ethernet LAN. By upgrading the turbine control system Con Edison will be improving the reliability of these units by increasing the troubleshooting capability, enhancing cyber security, replacing obsolete circuit card and communications protocol. The upgrade also improves graphics, alarm/event management, and trending.

Project/Program Title ER 10/20 DCS Windows Upgrade






Status Active


Work Description: This project will upgrade the retired Solaris operating system components on East River’s Distributed Control System (DCS) associated with Units 10 and 20 with new Emerson Evergreen Ovation DCS components. This project will replace the Solaris components with Windows based operating system components. The Ovation Evergreen program plans for replacing the no longer manufactured components, including networks, workstations, controllers and system software with the latest releases and security features without replacing the entire control system. The DCS I/O modules will not be replaced during this upgrade. The currently installed R-Line cards will continue to be supported by Emerson into the future. This upgrade will also put the Turbine control and Emerson DCS on the same communications protocol (Ethernet), alleviating any communication issues and ensuring reliability. Justification: As of November 2008, the Solaris based DCS components installed at East River Units 10 and 20 were classified as “retired” by Emerson. Emerson cannot continue supporting the Solaris based components because the components are no longer manufactured by Sun Micro Systems. Therefore, the components will need to be replaced with Windows based components. In conjunction, another capital project will replace future unsupported GE Gas Turbine control system components with Windows/Ethernet based operating systems. This will also necessitate the Emerson DCS upgrade in order to keep seamless communications between the new GE gas turbine control system and the Ovation control system ensuring a common operating system for enhanced reliability and controllability.

Project/Program Title ERSSS – DCS I/O Cards Replacement






Status In Planning


Work Description: This project involves the replacement of DCS cards. The implementation of this project requires replacement of all the old WDPF Q-CARDS with new R-CARDS and all the other components associated with I/O cards for Unit 7/70; reprogramming the software to reflect the new changes; testing the Data Base, Graphics and Control Logics to confirm the new replacement; upgrading Ovation software to Windows, system level 3.2; and completely replacing DPU 5/55 (including the enclosure). Justification: Replacing WDPF I/O with R-line I/O will complete the controls modernization for East River Station and allow the Ovation system to run at its full abilities, without a technological bottleneck at the I/O of the control system. The technological modernization can generate many synergies with future capital projects by using remote cabinets and reducing conduit and wiring runs. HART feedback will give operations and I&C additional process information while a future installation of an AMS PC on the network(s) will allow for better valve maintenance and troubleshooting. Removal of WDPF I/O will also allow East River to purchase stock replacement power supplies from Emerson.

Project/Program Title ER 1&2 Exciter Upgrade






Status Planning

Estimated Service Date November 2013 Work Description: The Combustion Turbine Generator Excitation System (EX2000) is a microprocessor-based power converter that produces controlled DC output for generator excitation. The EX2000 fully integrates with the Mark V turbine control where all control signals are written to and from the exciter on the ARCNET data link for data logging and reporting. This project will upgrade the current EX2000 to EX2100e Digital Front End (DFE). This upgrade package would replace all the unsupported circuit cards in the primary and backup power bridges, as well as the protection and auxiliary module. The EX2100e DFE also upgrades the auxiliary module to the latest exciter technology and Ethernet standard. This will allow for full integration with Mark VIe Migration controls and the complete elimination of ARCNET. Network infrastructure will require running new conduit and Ethernet cable between each generator control room (LEECC) and turbine control room (PEECC). Justification: An End-Of-Life (EOL) notice was distributed by GE in 2004, which gives the system supportability until 2014. Past that, no further Technical Assistants (TAs) will be trained on the EX2000, and parts will no longer be supported. With the current configuration, the only option will be to self maintain the EX2000 with existing spare parts and suppliers, and develop and secure long-term network of TAs to support the station for various troubleshooting issues. Also, ARCNET communications protocol no longer meets IEEE standards and will require conversion to 100MB Ethernet LAN. By upgrading the excitation control system Con Edison will be improving the reliability of these units by increasing the troubleshooting capability, enhancing cyber security, replacing obsolete circuit card and communications protocol. The upgrade also improves graphics, alarm/event management, and trending.

Project/Program Title 59th Street PB – Airflow Modification (Boiler 116/117)






Status Planning


Work Description: The scope of work is to install new turning vanes in the air inlet duct work to the burners immediately downstream of the air heater to stabilize the airflow at all loads. This includes installing four main turning vanes along with a divider plate. The new vanes will be installed from the front, sloped wall of the ductwork. This will eliminate the vortices that occur near the air flow probes at lower loads, resulting in a more stable airflow measurement. Justification: The duct supplying the wind-box expands in two directions as it enters the wind-box causing strong vortices upstream of the airflow probes. The airflow measurement is effectively the feedback for FD fan inlet vane control; therefore any disruption in airflow measurement may cause a disturbance in actual airflow which could result in poor combustion and possible opacities. Providing steady airflow will help to accomplish better boiler operation. Estimated Service Date: May 2013 Status: Planning Current Working Estimate (if applicable): Funding ($000):

Project/Program Title 74th Chemical System Monitoring






Status In Planning


Work Description: The Public Service Commission (PSC) has designated steam purity limits for several chemical parameters in the steam send-out as stated in COP 9-1-2. These chemical parameters are currently monitored using a combination of electronic analyzers and hand samples. The use of hand samples can cause delayed analysis results on certain chemical parameters that need a more efficient means of results indication. Also, accelerated degradation of the steam equipment can occur if certain chemical and pH levels are not properly maintained in the system.

Justification: Install the necessary chemical analyzers and probes to allow improved real time indication to the operators so the system can be more effectively maintained and operated to ensure that the steam purity and quality stay within the requirements of the PSC and to ensure accelerated equipment degradation does not occur. The readings from the instrumentation will be provided locally at the instrument as well as remotely on a display in the control room and in PI. The instruments will be unitized using separate I/O cabinets for the package boilers and the high pressure boilers. The instruments associated with the package boilers will be connected to the existing DCS, while the instruments associated with the high pressure boilers will be connected to the DCS that’s being installed with the new demineralization project.

Work Description: The PB BMS Input Daisy Chain has to be eliminated by adding a Watchdog Timer Relay. Each BMS tripping switch (or device) should have its own separate PLC input. The PB BMS ID Fan Running and FD Fan Running signals should be reconnected to the separate PLC Inputs. Also, PB BMS PLC should be modified with high time resolution sequence of event module to identify real source of the Trip. The PB BMS PLC Program should be modified to get correct First Out Alarm to identify real source of the Trip. PB BMS program should be modified to have reasonable time delay for the trip signals including "ID/FD Fan Tripped". Lastly, PB BMS should be modified to able to work together with PB BMS. Justification: Package boiler BMS has significant deficiencies that make hard troubleshooting of the boiler trips.

1. BMS is not providing correct "First Out" alarm to define the real cause of the boiler trip. 2. BMS has input daisy chain of trip switches inputs that make the troubleshooting very complicated. 3. BMS program is not separated per functions (fuel selection, purge, ignition, burner 1, burner 2, and

alarms) that makes difficult troubleshooting of the trips. 4. BMS does not have high time resolution sequence of events module that helps to find the real root

cause of the trip. 5. PB BMS is not ready to work together with designed PB DCS.

Project/Program Title ER - All Load Cycle Control/Autotune





Project Number TBD

Status In Planning


Work Description: The East River gas turbines are GE 7FA Units designed to be operated with a high power density and low combustor emissions. To achieve these goals, the combustion process for each Unit must be optimally tuned to achieve minimal combustion emissions while maintaining sufficient margin to flame blowout and mechanical combustor fatigue. The latest product from GE to improve Unit performance and reduce tuning and maintenance costs is AutoTune. This system is designed to provide inputs to the turbine control system and tune the Unit continuously in real time. While the present system tunes in real time, it is not continuous and only occurs when Operations schedules the maintenance to performed with the GE Remote Monitoring System. In order to the install AutoTune, the turbine control system must be upgraded to what is known as All Load Cycle Control. This upgrades the control system from a reactionary, schedule based system to a predictive, model based system. This upgrade can be completed once the Mark V turbine control system modernization is completed in 2013 Justification: When initially installed, a GE onsite technician was required to manually tune each Unit at the cost of several tens of thousands of dollars per tune, and several days per Unit. In 2006, the Units were upgraded with a remote monitoring and diagnostics system that among other things, allows GE to monitor and adjust tuning remotely. Once the Autotune system is installed, the Unit will operate at peak combustor efficiency for the instantaneous environmental conditions, and will eliminate seasonal tuning costs and inefficiencies.

Project/Program Title Equipment Access Platforms(2)

Functional Program Structures




Project Number 24159th-10

Status Planning


Work Description: At East River Station multiple ladders, walkways, stairs and railings are required to allow access to various new and existing components throughout the station. In some cases these egress systems were built out of wood as temporary structures. Some platforms are currently supported by temporary scaffolding, and some areas simply have no access or fall protection thus presenting a safety concern. Limited to no access is allowed in those areas of the plant until proper controls are installed to satisfy the RWLB fall protection criteria. At the present time there are at least 10 areas where either wood or scaffolding is being used for access, no access exists, or access is blocked. The lack of proper permanent (steel) access structures impedes the Operator's ability to complete their rounds as efficiently and safely as possible and also precludes effective maintenance in some areas. The wooden structures also pose a potential fire hazard which once destroyed will reduce the ability to access some areas of the plant and successfully extinguish the fire. This project will provide steel platforms, ladders, extensions to improve operator access to equipment at the East River Station. The areas of work are shown on the following table: Justification: The lack of proper steel access structures impedes the Operator's ability to complete their rounds as efficiently and safely as possible and also precludes effective maintenance in some areas. The wooden structures also pose a very significant fire hazard, not only by the fact that they are flammable, but once ignited will quickly be destroyed completely cutting of fire access to some areas of the plant.

These immediate repairs will restore the structural integrity of these tunnels until more permanent repairs can be implemented during the following five years. Note: the permanent repairs are not part of this project. Justification: The Intake tunnel was originally constructed in 1918 and the Discharge tunnel was built in 1902. Both tunnels were extended at the west end under Unit #10 in 1952, and again under Unit #9 in 1956. The Discharge tunnel is active and used by the station for discharge to the East River within limitations/criteria of the current SPDES permit while the Intake tunnel is inactive. Overall, both primary and secondary portions of the Discharge tunnel were observed to be in poor condition and require repair with 2 year to avoid an “unsafe” condition. Erosion of walls and soffit (ceiling) in the tunnels are extensive. In some cases, erosion up to 12” deep, where the steel reinforcement was completely corroded has been observed. Overall, the Intake tunnel is in fair condition with some localized deteriorated areas.

Project/Program Title 59th TWIC Implementation

Functional Program Security





Status On hold pending TSA decision


Work Description: This project will consist of installation of surveillance equipment at Con Edison steam generating station docks and piers to ensure that only those individuals who are authorized under the Transportation Worker Identification Credential (TWIC) program are granted unescorted access to these waterfront locations. This will require installation of new biometric card readers to interface with the federally issued TWIC identification cards. In addition, surveillance cameras, proximity card readers, and other access control equipment will be installed to support this program. The TWIC implementation will ensure that only authorized individuals are granted unescorted access to secure areas of the nation’s maritime transportation system. Justification: TWIC is administered jointly by the Transportation Security Administration and the United States Coast Guard. Implementation of this program is mandated by these federal agencies for waterfront access locations at Con Edison Steam stations. Con Edison steam facilities are capable of berthing maritime vessels primarily for fuel deliveries. These vessels could be used by individuals to threaten national security. The United States Congress has established TWIC through the Maritime Transportation Security Act to correct a deficiency in the security of the nation’s maritime transportation system. Con Ed steam stations are also classified as MARSEC (Maritime Security) sites and are required to meet security requirements.

Project/Program Title 60Th – NOx Project






Status Planning

Estimated Service Date June 2014 Work Description: The scope of work includes modifying the existing boiler system to reduce the NOx emissions on the Package Boilers. A potential installation of IFGR systems was found to be reasonable per new NYSDEC NOx RACT regulations. The system takes flue gas, via installed ductwork, from the ID Fan outlet flue and injects (recirculates) it into the FD Fan intake duct. A damper controls the amount of recirculated flue gas flow. The addition of flue gas to the inlet air lowers the oxygen content (percentage). This slows the combustion rate of the fuel; reducing the peak flame temperature, which in turn reduces the formation of thermal NOx. Replacing the existing burners to a low NOx emission burner is also considered to be a feasible solution. The design uses the free-jet method of mixing the fuel gas ejected from the gas tips with the surrounding inert products of combustion which dramatically lowers thermal NOx production. A high turndown ratio of 10:1 or greater will be achieved in most cases. Research and Development (R&D) testing in 2013 will be conducted to validate the consistency of this technology. Justification: The NYSDEC has implemented legislation to reduce the NOx emissions limits. The new NOx RACT regulation goes into effect July of 2014. As part of the company’s NOx plan, a request was submitted and approved to extend the compliance date to 2015. The NOx RACT plan submitted by the Company has the 60

th St PB group complying with the regulation as an individual emissions unit. Thus the units must now

stand on their own NOx emission rate, as opposed to being part of a system wide bubble average. As part of complying with the regulation, several methods have been considered to be a potential resolution and bring the units NOx emission compliance.

Project/Program Title 59th PB – NOx Project (Boiler 116/117)






Status Planning


Work Description: The project scope includes modifying the existing system to reduce the NOx emissions on the Package Boilers. An installation of IFGR systems was found to be the ideal solution. The system takes flue gas, via installed ductwork, from the ID Fan outlet flue and injects (re-circulates) it into the FD Fan intake duct. A damper controls the amount of re-circulated flue gas flow. The addition of flue gas to the inlet air lowers the oxygen content (percentage). This slows the combustion rate of the fuel; reducing the peak flame temperature, which in turn reduces the formation of thermal NOx. Justification: The NYSDEC has implemented legislation to reduce the NOx emissions limits. The new NOx RACT regulation goes into effect July of 2014.

Thus the units must now stand on their own NOx emission rate, as opposed to being part of a system wide bubble average. As part of complying with the regulation, the installiation of IFGR systems on these package boilers will help to meet the regulations.

Project/Program Title 74th St. – North Trenches in Boiler Building






Status Planning


Work Description: The scope of work includes the addition of new drain trenches in the Boiler Building north of column line XC between column lines 106 and 131. The new trenches will be connected to an existing sump at column line 120 adjacent to the north building wall. Justification: A recent modification project eliminated most of the unused basement trenches and this resulted in all remaining active sumps and trenches (within the station basement) being sealed and repaired. Since then, the north-end of the station has experienced local flooding in the basement area north of column line XC. This created hazardous conditions for station personnel and may jeopardize sensitive equipment during severe rain-fall conditions.
