Arizona Utility SRP Seeking Proposals for Non-Lithium, 10-Hour Energy Storage Solutions   

Arizona utility Salt River Project (SRP) has launched a request for proposals for non-lithium-ion, long-duration energy storage (LDES) demonstration projects as a part of its goal to increase renewable energy capacity in the state. 

It is seeking inverter and non-inverter based LDES technologies with capacities of 5 MW to 50 MW with 10-hour durations.

With a target online date of 2028, this storage system will be located at the Copper Crossing Energy and Research Center in Florence, Arizona, which will also host CMBlu Energy’s “Desert Blume”, a 5 MW, 10-hour LDES project. 

According to SRP’s recent Integrated System Plan, the utility will need to at least double its power resource capacity from a broad range of technologies over the next 10 years in order to provide affordable, reliable, and sustainable energy.  

Through this RFP and pilot process, the utility will work to better understand emerging non-lithium LDES technologies, as well as their performance capabilities and costs.  

“We’re seeking proposals from emerging storage technologies to consider how they could support achieving SRP’s sustainable power system of the future,” said Chico Hunter, Manager of Innovation and Development at SRP, in a statement. “We’re proud of SRP’s many lithium-ion battery storage projects coming online, and with the significant growth in our service territory, it is important we continue to pilot new types of energy storage technologies.” 

A notice of intent is due by July 10, 2024, and final proposals will be accepted until November 22, 2024.
