Portfolio

30 MW AC 35 MW DC operating photovoltaic dual axis solar facility. Whetstone successfully re-powered the facility to monocrystalline photovoltaic from the originally designed high concentrating PV, retaining dual axis tracking technology. This re-powering was completed in Q1 of 2025.

Located in the San Luis Valley of Colorado at an elevation of approximately 7000ft, this facility has excellent solar irradiance resource.

Potter Road Powerhouse is a portfolio of four natural gas-fired reciprocating engine peaking generation assets located in Braintree, Massachusetts, across two co-located sites. The facilities provide dispatchable peaking capacity under long-term contract to Braintree Electric Light Department (BELD), a municipal utility. Whetstone Power acquired the portfolio in 2024 and continues to operate the assets, delivering reliable capacity, transmission, and energy value to the local grid.
