ENGR ARSHAD CHUGHTAI CONSULTANT PLANNING (POWER) NTDC
Background
• Only a portion of the solar energy hits the Earth
• The remainder either returns to space• Or is absorbed by the atmosphere• Upon contact with the incident radiation, the
Earth heats up and emits this energy in the form of infrared radiant heat
• Directed towards space, a portion of this radiation is intercepted and absorbed by the greenhouse gases.
The Greenhouse EffectThe Greenhouse Effect is a natural phenomenon that allows us to survive on Earth. Without the greenhouse effect, average global temperatures would be – 18oC rather than the current 15oC.
The green house effect is the process by which absorption and emission of infrared radiation by the gasses in the atmosphere warm planets lower atmosphere and surface. It was proposed by Joseph Fourier in 1824 and investigated quantitatively by Svante Arrhenius in 1896.
Global Warming is an increase in the average global temperatures caused by an increase in concentration of gases that trap the sun’s energy.The global mean surface temperature increased over the 20th century by about 0.6oC.
Resulting Impact Snow cover and ice extent have decreased; Global average sea level has risen and ocean heat content has
increased. Higher maximum temperatures and more hot days over nearly
all land areas; Higher minimum temperatures and fewer cold days and frost
days over nearly all land areas; More intense precipitation over numerous regions; Increased summer continental drying and associated risk of
drought over most middle latitude continental land areas; Increase in number of infectious diseases due to higher
nocturnal temperatures (malaria already reaching higher altitudes where it was previously unknown).
Fall in agricultural production of staple crops such as wheat and corn due to higher temperatures.
Sources Green House Gasses
Carbon Dioxide (CO2) – Stems from combustion of fossil fuels, linked to transport and the production of heat or electricity, certain industrial process; deforestation.
Methane (CH4) – Stems from agriculture, oil and gas activities, and waste management activities.
Nitrous Oxide (N2O) – Stems from agriculture, the chemical industry and combustion activities.
Sulfur Hexafluoride (SF6), Per fluorocarbon (PFC), and Hydro fluorocarbon (HFC) stem from specific industrial processes (manufacture of aluminum, or magnesium, the semi-conductor industry), and from aerosols, air conditioning and insulating foam.
The Kyoto Protocol 1997 International treaty signed in Kyoto Japan:• Sets an emission reduction target for 40 industrialized
nations: Overall, nations must reduce GHG emissions by 5% below 1990 levels.
Because each GHG is different and has different global warming impacts, emission reductions described in tCO2-eq.
• 1 tonne of CO2 = 1 tCO2-eq=1 carbon credit• 1 tonne of CH4 = 21 tCO2-eq=21 carbon credits• 1 tonne of N2O=310 tCO2-eq=310 carbon credits• 1 tonne of PFC = 9,200 tCO2-eq= 9,200 carbon credits.• 1 tonne of SF6 = 23,900 tCO2-eq=23,900 carbon credits
On average, each Mega Watt hour (Mwh) of electricity generated in the U.S results in the emission of 1,341 pounds of carbon dioxide (CO2), 7.5 pounds of sulphur dioxide (SO2) and 3.55 pounds nitrogen oxide (NOx). Thus the 10 million Mwh of electricity generated annually by US. Wind farms represents about 6.7 million tons in avoided CO2 emissions, 37,500 tons of SO2 and 17,750 tons of NOx. This avoided CO2 equals over 1.8 million tons of carbon, enough to fill 180 trains, each 100 cars long, with each car holding 100 tons of carbon every year.

EMISSIONS FROM FUEL ENERGY CHAIN
Kyoto Protocol and Carbon Credits
• Provides financial incentives for investors in developing countries to invest in most efficient and environmentally friendly technologies;
• Facilitate the most cost-effective reductions of GHGs
• It costs comparatively less to reduce one tonne of CO2 in developing Countries than in the developed countries.
• It helps developing countries continue on path of industrialization and leapfrog over most pollution-intensive stages;
How to Implement Carbon Credit Projects
Invest in new, cleaner, more efficient technologies, such as the following:
• Construct and operate a wind farm or hydropower plant – will displace electricity produced from fossil fuels;
• Application of biomass fuels instead of fossil fuels, such as rice husk, biogases, or MSW instead of coal;
• Capture waste heat to produce additional electricity, thereby reducing overall fuel consumption;
• Replace older, less efficient equipment with newest models available in the market.
It is to ensure that investment in technology goes above and beyond the environmental performance of the business-as-usual scenario in the country.
Carbon Credit Project Process
The project must first be approved by host country and validated by a third-party auditor.
After validation, the project is submitted to the United Nations for approval by the Clean Development Mechanism Executive Board.
For validation and approval, the project must first meet certain eligibility criteria, as well as use an approved methodology for determining emission reductions.
Subsequent approval, the project is closely monitored to ensure that emission reductions are achieved. Monitoring data will be evaluated by a third-party auditor.
Carbon Credits are only issued once monitoring data are verified by the auditor and the issuance is approved by the United Nations.

Criteria Country is a signatory to the international treaty to
climate change and has ratified Kyoto Protocol and set up DNA for approve projects.
Project must reduce/displace one of the six greenhouse gases.
Project must not have been commissioned yet. Emission reductions should be additional to
emission reductions that would occur under normal business-as-usual scenario.
Required funding must not divert official development assistance.
Project must contribute to the country’s sustainable development.
Project must use technology that is readily available in a market.
Criteria
Carbon Credit revenue essentially to be a part of feasibility study. If a project has already commissioned – and it has not got carbon credits– that means it did not need carbon credits in the first place.
Carbon credits are intended to provide a financial incentive to invest. But if one has already invested without considering carbon credits, apparently such incentive was not required.
Additionality The Clean Development Mechanism provide
financial incentives to invest in new / more efficient / cleaner technologies.
It is essential to prove Additionality. Carbon credit revenue need to play a role in
decision-making while considering investing in a project!
What are the barriers to your investment? Barriers on Investment: Cost, financial penalties,
lack of available service providers, lack of skilled technicians, etc.

Project Idea Note (PIN)
PIN – Project sponsors / proponents submit potential projects for consideration to the CFU in the form of a Project Idea Note (PIN).
Early Notification and Letter of Endorsement (LoE)
LOE – If the PIN was submitted by a third-party project sponsor, and the CFU decides to develop it further, the Host Country (e.g the UNFCCC National Focal Point) will be notified of the project.
Carbon Finance Document (CFD)
CFD – CFU experts will investigate further and evaluate particular aspects of the project in discussions with the project proponent and prepare a CFD with the risk assessment.
Letter of Intent LoI
LOI – The CFU formally signals its intention to purchase emission reductions generated by a specific project under terms agreed in return for the exclusive right to contract for the purchase of emission reductions.
World Bank Due Diligence
World Bank Due Diligence – All projects must comply with World Bank Group Operational Policies and Procedures, including those on environmental assessment. An Integrated Safeguard Policies review and Environmental Assessment (EA) is performed as a standard part of the appraisal of World Bank Group Projects.
Baseline Study (BLS) and Monitoring Plan (MP)
BLS and MP – Once the CFU has decided to include the project in the Portfolio, it will commission a Baseline Study and Monitoring Plan, if the project is not applying an approved methodology.
Project Design Document (PDD)
• PDD – A project – specific document required under the CDM which will enable the Operational Entity (OE) to determine whether the project:– (i) has been approved by the parties involved in a
project,– (ii) would result in reductions of greenhouse gas
emissions that are additional,– (iii) has an appropriate Baseline and Monitoring
Plan. The PDD is prepared by the CFU and project sponsor.
Validation
Validation – After the BLS, MP and PDD have been satisfactory developed, the CFU engages an Independent Validator (Designated Operational Entity, DOE) to validate them. This means that the Validator agrees that the ERs are additional to the baseline, the MP is sufficient, and that the ERs have a high chance of being certified under the Kyoto Protocol.
Registration
Registration – The designated Operational Entity (DOE) contracted to undertake validation, upon the request of the CFU, submits the validation report and validation opinion to the Executive Board, along with a request for registration, together with the PDD, Baseline Study, MP, stakeholder consultation documentation and LoA, plus any other appropriate supporting documentation.
Negotiation of Emission Reduction Purchase Agreement (ERPA)
Negotiation of ERPA – After the consultations, the CFU legal team prepares a ‘term sheet’ and/or a draft ERPA for further discussion the project sponsor.
Initial Verification / project commissioning
Initial Verification / Project Commissioning – After the project’s construction and before its commissioning to produce ERs, the CFU contracts an Independent Third Party (a Verifier) for the project (different from the Validator). The Verifier will establish contact with the project and undertake an Initial Verification, which should confirm that the project is ready to generate verifiable and certifiable ERs. This will trigger the CFU acceptance of ERs from the project.
Monitoring
• Monitoring – As part of project implementation, the project operator must implement the MP, which provides a methodology and a tool for measuring and calculating the emission reductions generated by the project. Once the project starts to generate emission reductions, the project entity monitors the project in accordance with the MP.
Verification and Certification
• Verification and Certification–Verification and certification of the emission reductions will be undertaken periodically in accordance with the MP and other applicable guidelines by a DOE, who is contracted for the project by the CFU. The verifier will submit a verification report to the UNFCCC CDM Executive Board (EB) for a certification, which will confirm that the ERs have been achieved in the verification period in compliance with applicable CDM rules.
Transfer of Certified Emission Reductions (CERs)
• Transfer of CERs – Once the ERs are certified, the CFU will pay for the amount of ERs as agreed in the ERPA and the ERs are transferred to Participants in accordance with the ERPA and / or Host Country Agreement and applicable UNFCCC or other rules.

POWER SECTOR CARBON CREDIT PROJECTCONVERSION OF THE EXISTING 366MW STREET LIGHTING
LOAD TO SOLAR POWER SYSTEM.• The Solar Lighting Systems consist of Lighting Equipment (lamp) with a rechargeable
battery and a photovoltaic module. Photovoltaic (pv) modules consist of solar cells which can convert sunlight directly into electricity.
• Solar LED street lights present the perfect and cost-effective solution for residential streets, roadways, and other general area lighting applications.
• Solar street lights can be economically viable and efficient in a number of applications. Due to their low power consumption and very long life-span, solar LED street lights are a good alternative to LPS (Low Pressure Sodium)
• Unlike LPS lamps that produce a yellow-orange light, Solar street lights using LED technology generate a very powerful and targeted crisp white light of excellent quality, which significantly improves color rendition and night visibility.
• Project Highlights.• PEPCO intends to convert the existing street lightning load to solar power system. • PEPCO has jurisdiction over 10 Distribution Companies (DISCO’S)• LESCO, FESCO, CEPCO, MEPCO, IESCO, PESCO, TESCO, QESCO, HESCO & SEPCO.• Total number of Street Light Connections in Disco’s is 83302.• Load of street lights :366 MW• DISCO wise break up of street light connections is as under:
• LESCO: 1837• GEPCO: 458• FESCO: 1375• MEPCO: 1255• IESCO: 1438• PESCO: 838• HESCO&SEPCO: 863• QESCO: 238• TOTAL: 8302• Number of Lighting Points: 639704* • Local Bodies involved are also being dovetailed into the project.

POWER SECTOR CARBON CREDIT PROJECTPROVISION OF LT CAPACITORS ON INDUSTRIAL AND
AGRICULTURAL LOADS • Among the various energy conservation measures, improvement of
low power factor is an area where significant potential for saving exist. The power factor on the Industrial and Agricultural loads can be improved easily by the use of power factor equipment and is normally achieved by a suitable amount of capacitors load to compensate for the presence of inductive load in the system. Poor power factor on the system is also main cause of energy losses.
• To improve the low power factor on LT side PEPCO has envisaged a plan to install LT capacitors on Agricultural Tube well and small industrial connections as well having load up to 40KW.
• Total Number of Agriculture Tube well Connections in to DISCO’s :27875
• Load on Agricultural Tube well Connections in DISCO’s: 3511 MW.• Total Number of Industrial Connections up to 40KW load in to
DISCO’s: 239266.

POWER SECTOR CARBON CREDIT PROJECTREPLACEMENT OF ENERGY INEFFICIENT IRRIGATION TUBEWELL PUMPS/MOTORS WITH ENERGY EFFICIENT
STANDARD PUMP/MOTORS• One million tube wells in the country heavy on power and fuel are known to be extremely inefficient in operations.
• Total number of agriculture tube wells installed in DISCO’s is 278475 with the load of 3511 MW, (Out of which the number of tube wells are 219584 with a sanctioned Load of 2908, 858 MW) while the remaining are diesel driven pumps.
• According to survey carried out by ENERCON and other consumer groups the efficiency of the present pumps is only 30% of the standard equipment. The pump sets are old centrifugal, turbine or submersible.
• Tube well Efficiency Improvement Program (TWEIP)• USAID has initiated a Tube well Efficiency Improvement Program. A
pilot program focusing within the jurisdiction of Multan Electric Power Company (MEPCO) to replace, 1000 old and inefficient agricultural tube well pumps sets (Pumps and Motors) with energy efficient tube well pump set has been commenced. USAID is Subsidizing 50% of the equipment cost for the farmers. The country wide program has a target a total number of 1000 tube wells in seven DISCO’s (MEPCO, FESCO, LESCO, GEPCO, IESCO, HESCO & PESCO).
• Energy Savings• Post replacement audits on 324 sites concluded that average
pump set Energy Efficiency (%) has been enhanced from previous 37.45% to 54.85% and the average demand per pump set (Kw) reduced to 12.57 Kw from 19.57 Kw previously meaning there by 5.38 Kw savings per pump set replacement.
• On the basis of above Taking into account the total number of in-service/active Tube wells in the DISCO’s the Energy Savings to be generated from the replacement of old and inefficient agricultural tube well pump sets with energy efficient tube well pumps sets will be = 219584x5.38Kw = 1181 MW
• Estimated Power Saving: 1181 MW• Average Operational Hours: 10 hours per day.

ACTIVITY PEPCO Manages 10 DISCOS, (LESCO,FESCO, GEPCO, MEPCO,
IESCO, PESCO,TESCO, HESCO, SEPCO & QESCO) More than 20.05 million customers are served through primarily Electro Magnetic Meters and lately Digital meters have also been inducted. The Digital Meters have a proven record of reducing the line losses by eliminating theft of electricity.
PEPCO intends to arrange for a remote system capable of measuring electricity consumption/ Customer usage besides generating all other information and data needed to run its specified Management information system (MIS) without the glitches inherent to the existing normal system. A major requirement of the system is to control the present level of administrative losses i.e. pilferage, theft and stealing of energy constricted installation of energy meters by-passing of the same and other such internal and external features. Introduction of Advanced Metering Infrastructure (AMI) fully incorporating RMS/AMR systems is expected to relieve the Distribution system of the present extravagant use / wastage. Consequently thereby it will significantly relieve the generation system.
AMI and Its Benefits
• AMI, in its essence, serves to move data and control signals between a consumer’s energy consumption and the DISCO that provides the electricity. The most basic level of AMI is called automated meter Reading (AMR). More sophisticated use of AMI involve two – way communication between the Distribution company and the smart Meter so data is transmitted in real time to the distribution company and tariffs and other control signals can be sent to the meter.
• Benefits:• Customer service is improved through Remote Meter Reading and efficient
data management. Power outages can be detected, identified and corrected more quickly for customers whose meters are connected to and work.
• Direct load Control: AMI allows for the energy flow to be set at a peak threshold on a per meter basis at specific times during the day. This allows the distribution company to do load shedding without having to completely switch off entire feeders as is currently the case. Peak usage is minimized. Consumers can benefit from lower electricity bill by using smart card controlled energy meters. Improve metering accuracy despite nonlinear loads.
