Invenergy and Grant PUD Break Ground on 120 MW Quincy Solar Energy Center in Washington

Invenergy and Grant County Public Utility District (Grant PUD) have broken ground on the 120 MW Quincy Solar Energy Center in Washington, marking Grant PUD’s first solar project in Grant County and Invenergy’s first solar project in the state to reach the construction stage.

The groundbreaking ceremony was held on August 18, 2026, at the project site near Moses Lake, Washington. Once operational, the solar facility is expected to generate enough electricity to supply the equivalent of more than 25,000 Washington homes.

The project is expected to reach commercial operations in late 2027. It will provide additional renewable generation to the local grid as Washington faces rising electricity demand and increasing pressure on its power infrastructure.

Quincy Solar is expected to support more than 200 jobs during peak construction and contribute more than $27 million to the local economy over the project’s lifetime through land lease payments, local taxes and other expenditures.

As part of the groundbreaking event, Invenergy presented a $20,000 donation to Grant PUD’s Share the Light programme, which supports local households facing difficulty paying their electricity bills. The programme is expected to assist more than 600 families in need.

The project is being developed by Invenergy, with Cupertino Electric serving as the engineering and construction contractor. Construction is being supported by IBEW Local 191, IUOE Local 302 and LiUNA Local 348.

“We’re proud to partner with Grant PUD on its first solar project in the county and help advance a shared goal of delivering reliable, affordable electricity while creating lasting economic benefits for Grant County,” said Mateo Gomez, Lead Developer for Quincy Solar at Invenergy.

Grant PUD General Manager and CEO John Mertlich said the project is an important part of the utility’s plan to provide clean energy to its growing customer base, as outlined in its 2024 Integrated Resource Plan.

Quincy Solar will also expand Invenergy’s presence in Washington. The company has developed four energy projects in the state with a combined generation capacity of more than 950 MW. Invenergy said its Washington projects contribute more than $12.1 million annually through local taxes, landowner payments, wages and other economic benefits.

The Quincy Solar Energy Center represents Invenergy’s first solar project in Washington to reach construction and is expected to contribute to the state’s renewable energy capacity while diversifying Grant County’s energy resources.
