08/31/2023 Southern Maryland Electric Cooperative and ICF: The FlexTemp Pilot

Gaining Maryland Public Service Commission approval in March of 2022, the SMECO FlexTemp Pilot moved quickly to stand up a flexible load management program directly associated with the management of smart thermostats, during both the cooling and heating seasons. The approach taken for the program was presented during PLMA's Spring 2022 Conference and was titled “Revenue and Emission Benefits of Managing Thermostats on a Sub-hourly Basis”.

The FlexTemp Pilot builds on SMECO’s innovative approach to utilizing smart thermostats, dating back to 2015, as one of the first utilities to provide incentives to customers for the installation of smart thermostats.

The FlexTemp Pilot achieved considerable success in 2022 and proves it's possible to manage behind-the-meter assets as grid resources, and that devices can also support decarbonization goals and plans. Additional impacts include:

• The ability to group cohort members and schedule dispatches on a day-ahead basis.
• Development of procedures to group cohort members and schedule dispatches on a real-time basis
• Learning customer behavior, which allows for seasonality of customer cohorting.
• Optimization of members enrolled to dispatch events to achieve firm service levels.
• Optimization of members enrolled to dispatch events to achieve guaranteed load drop.
• Events called based on optimization of energy savings
• Events called based on optimization of capacity savings
• Events called based on optimization of GHG emission reduction
• Ability to dispatch on a real-time basis instead of day ahead basis
• Members enrolled = 250+ with the expectation of exceeding 1,000+ by May 2023.
• Reduced member opt-out rate in comparison with traditional DR programs (~1.5% as compared to ~25%)
• kW/member saved on average per event: 1 kW
