Flex Rewards is a program for eligible Energy Wise Rewards customers that provides a more flexible experience for participants to help maintain energy grid stability while minimizing customer comfort concerns. Flex Rewards differs from Energy Wise Rewards in the following ways:

• Eligibility – During the summer season, eligible Flex Rewards participants may include customers with electric cooling equipment. During the winter season, only Flex Rewards customers with eligible electric heat pumps used for both cooling and heating will participate in events.

• Event experience – Flex Rewards events are typically shorter in duration (1-3 hours) compared to Energy Wise Rewards (2-4 hours), and Flex Rewards temperature adjustments are typically smaller (1-3 degrees) compared to Energy Wise Rewards (2-3 degrees).

• Event season – Flex Rewards conservation periods (or “events”) can occur any time of year, whereas Energy Wise Rewards events occur between June 1 and October 31.

• Event frequency – Flex Rewards events are generally more frequent than Energy Wise Rewards events, but overall, Flex Rewards events are designed to be unnoticed by participants with a lower temperature adjustment and shorter length.
