Reducing energy use from 2 to 6 p.m. Friday can earn Southern California Edison customers money toward their power bill.
It's one of the utility's Save Power Days, which it holds up to 12 times yearly.
The program compares a household's energy use during the four-hour stretch to the household's average usage from 2 to 6 p.m. during its three highest usage weekdays of the most recent five (excluding holidays or other Save Power Days).
If average electricity usage during the Save Power Day is lower, the customer will earn a bill credit of 75 cents per kilowatt reduced.
Customers must sign up for Save Power alerts at SCE.com to participate in the program.
To do so, sign into your SCE account; click the Savings Center tab; click "Learn More" in the Save Power Day Incentive box; then follow the enrollment directions.
