Millcreek households will see a new $4 monthly charge on their Rocky Mountain Power bills starting Jan. 1, 2027. The fee kicks in automatically unless residents opt out of a clean energy program their city joined in May.

The Community Clean Energy Program (CCEP) will automatically enroll Rocky Mountain Power customers in 16 Utah communities, including Millcreek. The program funds new solar, wind and geothermal projects, according to ABC4, which first reported the details Oct. 28.

Customers who want out can do so at no cost between Nov. 2, 2026, and May 1, 2027. After that, residential customers and small businesses face a $30 termination fee.

What it costs

Households that stay enrolled will pay a flat $4 per month, listed as a new "Schedule 100" line item on their Rocky Mountain Power bill, according to the Summit County Health Department.

Two groups are exceptions. Customers enrolled in Rocky Mountain Power's Home Electric Lifeline Program (HELP), a low-income assistance plan, participate at no additional cost. They receive a monthly bill credit to offset the charge. Residential customers with rooftop solar on Schedule 135 are not eligible and will not be enrolled.

For businesses, the cost is $0.00609 per kilowatt-hour plus a 12-cent low-income surcharge per month. ABC4 reported that adds an estimated 4% to 9% to commercial electric bills.

How to opt out

Rocky Mountain Power will mail notifications in November explaining the program and how to leave it. A second notice will follow in December by mail or email, depending on billing preferences.

Customers can opt out by mail, phone or online during the free window.

What the program builds

The CCEP is run through Utah Renewable Communities in partnership with Rocky Mountain Power. Sixteen cities and counties voted to join around the end of May, KPCW reported.

Utah Renewable Communities' board has selected two solar projects to advance into final contract negotiations, according to ABC4. Those projects are expected to connect to the electric grid between 2028 and 2030. Program leaders say the effort could eventually add up to 500 megawatts of new clean energy capacity.

Summit County Sustainability Director Emily Quinton urged residents to watch for the notices. "I want people to make an informed choice about their participation," Quinton said at the Oct. 5 Summit County Board of Health meeting, according to KPCW.

The other communities in the program are Alta, Castle Valley, Emigration Canyon, Francis, Holladay, Midvale, Moab, Oakley, Ogden, Park City, Salt Lake City, Springdale, unincorporated Grand County, unincorporated Salt Lake County and unincorporated Summit County.

Rocky Mountain Power's first enrollment notices are expected to arrive by mail in November.
