Synchrophasor OverviewAlthough we already know the many benefits of wind power, it is critical that we manage its effect on reliability of the grid before wind can become an efficient energy source in the Texas electricity market.

Our first task in this demonstration will be to monitor the ERCOT grid and its large-scale wind resources with Synchrophasor technology to detect and identify undesirable conditions on the grid, thereby enabling ERCOT operators to make adjustments to maintain grid reliability, and to expand the level of wind generation from available wind capacity.

9

Demonstration Goals Enable ERCOT to better manage the transmission grid to

accommodate very large quantities of wind generation

Establish and maintain a reliable synchrophasor network to provide real time dynamic information on wind resources and their impact on the transmission grid

Use synchrophasor measurements to identify precursor conditions to undesirable grid performance and behavior

Identify changes in operating procedures or actions to facilitate integration of intermittent resources, hence improving grid reliability

Utilize synchrophasor measurements to recalibrate engineering models

10

Demonstration Approach Build on Current ERCOT Network started in Fall 2008 with 3 AEP PMUs Currently 14 PMU’s installed at 12 TO locations, and at ERCOT

ePDCTM for data synchronization, RTDMS® for visualization, and PGDATM for off-line analysis

Expanding to 23 PMUs, provide TOs access to RTDMS visualization applications

Enable ERCOT to better manage the transmission grid to accommodate very large quantities of wind generation

Establish and maintain a reliable synchrophasor network to provide real time dynamic information on wind resources and their impact on the transmission grid

Use synchrophasor measurements to identify precursor conditions to undesirable grid performance and behavior

Identify changes in operating procedures or actions to facilitate integration of intermittent resources, hence improving grid reliability

Utilize synchrophasor measurements to recalibrate engineering models

RTDMSSynchrophasor technology measures variations across a transmission grid in absolute real-time. The measurement includes a time stamp that provides an easy method of correlating values from different locations that take different amounts of time to arrive at a common collection point. This gives us a tool to view the power system as a whole or to compare different points in real time.

SMT Portal OverviewERCOT and the largest electricity companies in

Texas have launched the most aggressive Advanced Metering System (AMS) deployment in the U.S.

The Smart Meter Texas Portal initiative is a several-year collaboration to:

Properly integrate AMS meters into the ERCOT market

Provide consumer tools for viewing 15-minute meter data

Provision devices for load control The PUCT formed an Advanced Metering

Implementation Team (AMIT) which is currently defining a roadmap for future SMT Portal capabilities

The CCET Project and all of its stakeholders will plan an extension of Portal capabilities that can be used to better support ERCOT as well as test aspects at the Texas Community of the Future.

15

Planning Goals Investigate large-scale residential load reshaping and

control techniques, leveraging the major deployment of AMS

Investigate the prospects of expanding the ancillary service market in ERCOT to include aggregated residential load and distributed battery systems

Investigate peak shaving effects resulting from residential energy efficiency initiatives

Investigate consumer response to alternative pricing strategies

16

Planning Approach Continue to assist with planning efforts for future SMT

Portal releases Assist with the development of use cases, requirements,

architectures and designs to support future needs Provide feedback on customer interaction with and

comments concerning SMT Portal As needed, develop new functionality to support retail

electric provider and/or customer access to SMT Portal data

Texas Future Community Overview

Leverage availability of efficient building envelopes for residential homes

Implement a variety of community- and residential-level smart grid technologies that will empower neighborhoods and consumers to conserve energy:

Solar (community and residential) Storage batteries (community and

residential) Electric vehicle charging stations

(community and residential) Smart appliances Home energy management (HEM)

systems Implement and evaluate customer response to

load shed and real-time price signaling

There is an existing Houston community called Discovery at Spring Trails that is developing energy efficient homes equipped with solar units and energy management systems. The developer, Land Tejas, has invited CCET to participate in this unique master-planned community. The intent is to:

Masco “Environments for Living (EFL) Certified Green”The EFL program is Energy Star rated and Certified Green. EFL provides 2 guarantees for the first 3 years of the home: 1) temperature throughout the home will never vary more than 3 degrees from the thermostat set point, and 2) energy use for heating and cooling the home will not exceed stated levels.

Tight construction

Fresh air ventilation

Improved thermal systems

Right-sized heating and cooling systems

Air pressure balancing

Internal moisture management

Combustion safety

Quality construction and materials “behind the walls”:

Also includes low emissivity windows, energy efficient lighting, water conservation devices, and Energy Star appliances.

22

Demonstration Goals Educate consumers on smart grid and energy efficiency Quantify home construction efficiency by comparing energy

use with comparable code-built homes in a neighboring community, Legends Ranch

Determine the demand response potential of four tranches of homes, from code-built to “deep-green” homes

Document consumer response to dynamic pricing models Determine the effects of residential generation Design an effective market transformation program Determine the economic value of community-level energy

storage, solar farm, and centralized electric vehicle charging Determine the likelihood of TFC technology transfer to retrofit
