Summary

The Murray City Council voted unanimously to join a 25-year power purchase agreement for the Fremont solar-plus-battery project through the Utah Associated Municipal Power Systems (UAMPS); the city’s allocation is about 7.862 MW and the combined solar-plus-battery price was discussed.

The Murray City Council on Oct. 21 approved a resolution authorizing the city’s share of the Fremont solar and battery project, a 25-year power purchase agreement (PPA) executed through the Utah Associated Municipal Power Systems (UAMPS).

The city’s entitlement under the transaction is 7.862 megawatts (about 7.9% of the 99 MW project). The PPA sets a fixed combined cost for the solar-plus-battery resource in the 25-year contract period; council and staff discussed the effective delivered price range for the combined resource, which staff presented as roughly $69–$74 per megawatt-hour depending on contract-year assumptions. UAMPS staff and project representatives said the project’s commercial operation date is targeted for Dec. 31, 2027, and that members were asked to finalize participation to secure federal tax credit timing.

UAMPS technical staff described why the battery is paired with solar: daytime solar generation can charge the battery (captured energy shown on UAMPS slides), and the battery then discharges later to better match municipal load peaks in the evening and provide a resource across more hours of the day. Council members noted the project will help replace short-term coal resources that are sunsetting in 2026 and provide a renewable resource that better aligns with Murray’s load shape.

Action: Council Member Goodman moved to adopt the resolution authorizing the Fremont Solar PPA transaction schedule under the UAMPS master firm power supply agreement; Council Member Cotter seconded. A roll-call vote was unanimous: Council Member Paul Pickett — Aye; Council Member Cotter — Aye; Council Member Scott Goodman — Aye; Council Member Diane Turner — Aye; Council Member Adam Hawk — Aye.

Ending: City staff said the PPA is part of a multi-resource portfolio that also includes other natural-gas and renewable developments. The project is expected to come online in late 2027 and to supply Murray with both renewable energy and renewable energy credits (RECs) attributed to the city’s share of the output.
