Peak Power Rewards (PPR) events are short periods, usually 2–4 hours in duration, when participants are asked to reduce their energy use to help manage high electricity demand or high market prices. These events are called by SIPC when peak demand or high prices are expected. By participating, you can earn credits on your electric bill.
Events most often occur during extreme temperature seasons: summer (June–August) between 2:00 p.m. and 8:00 p.m., and winter (December–February) between 6:00 a.m. and 10:00 a.m. and 4:00 p.m. and 9:00 p.m. However, events can happen any time of year if SIPC predicts high demand, high prices, or a grid emergency.
