Columbia Wind project

Advancing our energy future


The Columbia Wind project extends our historic presence in Columbia County and unites a coalition of partnering landowners committed to building a strong, resilient energy future. This project will create new construction jobs and ongoing positions in operations and maintenance once in service.

Columbia County is an ideal location for this project because of the existing electric grid infrastructure. The project, part of a multi-phase site redevelopment effort, will improve energy reliability and resilience and deliver great value to our customers. Pending approval, we could begin construction in 2027 and complete it in 2028.
