Annual test cycles air conditioning and/or electric water heaters for PeakRewards participants

BALTIMORE, May 20, 2015 – Baltimore Gas and Electric Company (BGE) announced that it will perform an annual test of the systems that cycle the central air conditioners and electric water heaters of customers voluntarily enrolled in the PeakRewards programs. PeakRewards participants receive bill credits by allowing their central air conditioner and/or electric water heater to be cycled during periods of peak electricity usage. Last summer, PeakRewards participants received nearly $23 million in bill credits.

“Each year, BGE carefully reviews all aspects of the PeakRewards program in an effort to continuously improve our system operations and communications with our customers,” said Robert D. Biagiotti, vice president and chief customer officer, BGE. “This annual test helps ensure our systems and customers are prepared for the summer when cycling events are likely to be called.” PeakRewards participants have received a letter informing them of the preseason test event and that their central air conditioner (A/C) will be cycled up to their chosen level of cycling: 50, 75 or 100 percent. Customers enrolled in the BGE PeakRewards Electric Water Heater program and the Energy Saver Water Heater Switch program will also be part of this preseason cycling event. During the event, program participants will have power to their water heater interrupted and no additional hot water will be produced for the duration of the event. Neither PeakRewards A/C nor Water Heater customers will be able to override participation.

PeakRewards participants are notified of cycling events, including the preseason test, through a number of channels. Notifications will be made by email for participants who have an email address on file with BGE. Participants are also encouraged to sign up to receive event notifications by text message. Text messages are an easy way to receive immediate notification about cycling events directly to a mobile phone. To update contact information and notification preferences, customers should visit bge.com/myaccount. Information about cycling events will also be posted to the PeakRewards Event Central website, BGEsavings.com/PeakRewardsEvent.

To minimize the impact of the test, the preseason event has been scheduled to coincide with mild temperatures between 10 a.m. and 2 p.m. on a weekday when many customers are less likely to be at home.

The more than 320,000 customers who participate in PeakRewards help reduce the likelihood of power outages when electricity use is highest—normally summer days with extreme temperatures. During an event, PeakRewards participants reduce BGE’s system load by approximately 428 MWs each hour; the equivalent amount of energy produced by a medium-sized power plant.
