Net metering in Utah: Provo, Lehi, and Rocky Mountain Power
Utah’s utilities don’t follow one rulebook. Here’s the honest, utility-by-utility picture for sizing solar right.
Why Utah is different utility to utility
Where you live in Utah changes how your solar is credited — and therefore how you should size a system. Most of the state is served by Rocky Mountain Power, but several cities run their own municipal utilities with different, and sometimes more favorable, rules.
Rocky Mountain Power: net billing (most of Utah)
Across much of Utah — including the Salt Lake City area — Rocky Mountain Power uses net billing, which credits exported solar below the retail rate, with different summer and winter rates. The takeaway: design around using your own power, often with a battery, rather than exporting it. RMP also runs a battery program that can pay you to let the utility draw on your storage.
Provo: near-retail netting
Provo City Power nets your production close to the retail rate, with credits trued up and zeroed each February while you remain grid-connected. Because the netting is near retail, the smart move is to size the system to your annual usage rather than oversizing for export. A battery in Provo is mainly a resilience choice, not an economic necessity.
Lehi: a municipal utility of its own
Much of fast-growing Lehi is served by Lehi City Power, a municipal utility that sets its own net-metering terms rather than following the investor-owned rules — though some addresses fall under Rocky Mountain Power. Because the rules differ by address, the first step in Lehi is always confirming which utility serves your home, then designing to its current terms.
Frequently asked questions
Does every Utah city have the same net metering?
No. Most of Utah is on Rocky Mountain Power’s net billing, which credits exports below retail. Municipal utilities like Provo and Lehi set their own rules — sometimes more favorable — so design should match your specific utility.
How do I know which Utah utility serves my home?
It depends on your address — even within a city, service can split between a municipal utility and Rocky Mountain Power. We confirm your utility before designing, because the credit rules change the economics.
