TRANSCRIPT
PEC is the nation’s largest electric cooperative, providing service to approximately 242,000 members in the Texas hill country.
Pilot Objectives
• Explore Smart Grid technology to help reach Board Conservation goal of 20% reduction
• Inform and empower our members to manage their energy usage
• Demonstrate ability to reduce demand during peak periods
• Demonstrate benefits of Smart Grid program to PEC, LCRA, and ERCOT
• Determine true program cost and benefits • Survey member satisfaction
Pilot Scope• 100+ residential participants• 2 small commercial participants• Pilot participants all on same feeder• Installed smart meter, and control devices on
air conditioners and water heaters, to enable two-way communication to PEC control center; participant maintained control over appliances
• PEC controlled appliances during peak periods• Pilot was operated for one year

• Load management information for all program participants is displayed in a single dashboard that PEC uses to view the aggregation of all pilot participants’ energy usage displayed in the form of ‘Available’ load
• An energy management solution that allows PEC to control load management resources as if it was a peaking plant
• During times of peak demand, PEC initiated control events that successfully reduced peak demand for the participants

Surveys• Post-Installation
• Post-Winter Curtailment Season
• Post-Summer Curtailment Season
Participant Feedback• Overall satisfaction with the program incrementally
increased over the life of the pilot• User experience with the temperature/thermostat is the
most important factor influencing dissatisfaction levels• More participants were aware of the summer events
than winter• Overall, participants want to help the utility better
manage their energy resources• Respondents indicated that the equipment installer was
an important source of information
Costs
• Capital Costs – meter with gateway, device controller(s), thermostat(s), installation
• O&M Expenses – data communication costs per meter, repairs/replacements
Benefits• Participants
– Potential energy savings– Individual profiles– Increased visibility– Manage devices from anywhere– Can opt out of events
• PEC– Reduce energy usage– Lower 4CP – lower costs– Increased customer interaction/satisfaction
• LCRA– Demand management– Decrease infrastructure/costs
• ERCOT– Maintain grid reliability– Decrease costs
Recommendations• Recruiting/marketing– Create a comprehensive marketing campaign– Leverage members’ want to help the utility better manage
energy resources– Emphasize the energy savings, and control through internet– Ensure participants have internet access
• Installation– Standardize process– Train installers– Welcome package, installer able to answer questions
Recommendations Cont’d• Participant education– Communication should refer to reference materials– Consider online video training– Specifically explain control events, and what is expected– Provide details on thermostat usage, and online
controls/programming– Periodic releases to manage satisfaction and knowledge– Include energy savings tips– Leverage customer affinity to reduce opt out rates
• Operations– Monitor opt out rates, minimize impact– Optimize event duration/quantity removed
Controllable Load Resource (CLR)• Consert certification as an ERCOT CLR– Proof of Concept (POC) Test Phase 1• Regulation Up Service• Responsive Reserve Service• Non-Spinning Reserve Service
– POC Test Phase 2• Primary Frequency Response• ICCP Link• Automated dispatch• Data
– CLR Test
