Holladay households will see a new $4 monthly charge on their Rocky Mountain Power bills starting in January 2027 under a clean energy program the city joined.

The Community Clean Energy Program (CCEP) automatically enrolls Rocky Mountain Power customers in 16 participating Utah communities, including Holladay. The program, run through Utah Renewable Communities in partnership with Rocky Mountain Power, aims to help participating communities move toward 100% renewable electricity over time, according to ABC4.

Residents who don't want to participate can opt out starting in November. ABC4 reported the opt-out window opens Nov. 2, though official program materials say only "November" without specifying a date. Customers can leave at no cost through May 1, 2027, by mail, phone or online, according to Summit County Health's program guide. After that, a $30 termination fee applies for residential customers and small businesses.

Rocky Mountain Power plans to send two notices before the program starts, according to the Summit County Health guide. The first, expected in November, will arrive by mail. A second is expected in December by mail or email, depending on billing preferences.

The city of Holladay's website confirms the $4 monthly rate for households and notes that financial assistance is available. Customers can opt out at any time and return to the standard Rocky Mountain Power plan.

Not everyone pays the same amount. Households enrolled in Rocky Mountain Power's Home Electric Lifeline Program (HELP), a low-income assistance program, will participate at no cost. They receive a $4 monthly bill credit that offsets the charge, according to Rocky Mountain Power's program page. Residential customers with rooftop solar on Rocky Mountain Power's Schedule 135 are not eligible and will see no change to their bills.

For Holladay businesses, the cost depends on electricity use. Non-residential customers will pay $0.00609 per kilowatt-hour plus 12 cents per month, adding an estimated 4% to 9% to electric bills, according to ABC4.

The fees fund new renewable energy projects. Utah Renewable Communities issued a request for proposals in 2025 and selected two solar projects for final contract negotiations in September, ABC4 reported. Those projects are expected to connect to the grid between 2028 and 2030. The effort could add up to 500 megawatts of new clean energy capacity to Rocky Mountain Power's system, according to ABC4.

The other 15 communities enrolled alongside Holladay are Alta, Castle Valley, Emigration Canyon, Francis, Midvale, Millcreek, Moab, Oakley, Ogden, Park City, Salt Lake City, Springdale, and unincorporated areas of Grand County, Salt Lake County and Summit County.

The free opt-out window runs through May 1, 2027, and more details are available at utahrenewablecommunities.org.
