Salt River Project seeks up to 650 MW to meet peak demand

Salt River Project is seeking between 100 MW and 650 MW of capacity to meet its future peak-hour demand requirements in its service area in Arizona.

The company is seeking capacity solutions that can generate electricity from existing combined-cycle combustion and steam turbines, energy storage charged from the grid and by renewable assets, reciprocating engines and simple-cycle turbines. The community-based, not-for-profit electric utility said in a Sept. 7 request for proposals that it is only seeking 100 MW of capacity from commercial and industrial demand response resources.

All resources that are submitted as proposals should reach commercial operations between June 1, 2022, and June 1, 2025. The company will consider only resources that can satisfy at least 50 MW of peak summer demand. The supply-side generation should be up and running between June 1, 2023, and June 1, 2025, while 50 MW of demand response resources should be operational by June 1, 2022, and the remaining 50 MW by June 1, 2024.

Salt River Project's resource plan indicates a need for incremental peaking capacity by the early 2020's to meet its customers' retail load growth. The capacity will also be needed to support the integration of planned renewable resources and satisfy a portion of Salt River Project's required capacity reserves.

The proposals are due by Jan. 15, 2019, and the final selection of the projects will be made April 30, 2019. Salt River Project will use Ariba for the solicitation proposes. Interest parties should register online at
