By 2024, 50% of the energy consumed by members will come from renewable resources

Our clean energy transition significantly expands renewable energy generation. We’re accelerating the retirement of our coal generation and adding clean energy in locations across our members’ service territories. We’re adding six utility-scale solar projects and two utility-scale wind projects, bringing our system up to over 2 gigawatts of renewables by 2024. This will include the most solar of any cooperative in the nation.
