Grant PUD Commissioners adopted Grant PUD's 2026 Integrated Resource Plan during their business meeting on Aug. 25.
Washington State-based Grant PUD's current power portfolio, combined with anticipated power-supply agreements, contracted renewable generation projects, and continued participation in wholesale energy markets, are expected to provide sufficient energy to serve customers through 2046.
Key resources include the upcoming Bonneville Power Administration Provider of Choice contract and the Quincy Solar and Royal Slope Solar and Storage projects, which are under development.
The IRP also found that Grant PUD remains on track to meet the requirements of Washington's Clean Energy Transformation Act (CETA).
Existing resources, supplemented by renewable energy credits (RECs), are projected to satisfy clean energy compliance needs until the utility approaches the state's 2045 target of 100% clean electricity. To meet that long-term requirement, the plan identifies the potential need to add approximately 800 Megawatts of solar generation between 2040 and 2045.
While the utility's energy outlook remains strong, the analysis identified a future capacity need.
Beginning in the summer of 2030, Grant PUD is forecasted to face a shortfall in Western Resource Adequacy Program (WRAP)-qualifying capacity. To address this need, the IRP recommends acquiring approximately 360 megawatts of energy storage resources between 2030 and 2032.
Additional IRP recommendations include continued participation in wholesale energy markets and joining SPP's Markets+ in 2028, ongoing involvement in WRAP, investments in conservation and energy efficiency programs, and continued monitoring of customer load growth and emerging energy technologies.
Under Washington state law, electric utilities must update their Integrated Resource Plans every two years to demonstrate how they will reliably and cost-effectively meet future electricity demand.
