Energy storage system integrator Powin Energy has signed a contract with Idaho Power to supply a 120MW/524MW battery storage system, the first utility-scale battery storage system in Idaho. energy storage project.
The battery storage projects, which will come online in summer 2023, will help maintain reliable service during peak power demand and help the company achieve its goal of 100 percent clean energy by 2045, Idaho Power said. The project, which still needs approval from regulators, may include two battery storage systems with an installed capacity of 40MW and 80MW, which will be deployed at different locations.
The 40MW battery storage system may be deployed in conjunction with the BlackMesa solar power facility in Elmore County, while the larger project may be adjacent to the Hemingway substation near the city of Melba, although both projects are being considered for deployment at other locations.
"Battery energy storage allows us to efficiently utilize existing power generation resources while laying the foundation for more clean energy in the years to come," said Adam Richins, senior vice president and chief operating officer of Idaho Power.
Powin Energy will supply the Stack750 battery storage product as part of its Centipede battery storage platform, which has an average duration of 4.36 hours. According to the information provided by the company, the modular battery energy storage platform uses lithium iron phosphate batteries provided by CATL, which can be charged and discharged 7,300 times with a round-trip efficiency of 95%.
Idaho Power has submitted a request to the Idaho Public Utilities Commission to determine whether the project proposal is in the public interest. The company will follow a request for proposal (RFP) from last May, with the battery storage system scheduled to come online in 2023.
Strong economic and population growth is driving demand for additional power capacity in Idaho, while transmission constraints impact its ability to import energy from the Pacific Northwest and elsewhere, according to a release from Powin Energy. According to its latest comprehensive resource plan, the state is looking to deploy 1.7GW of energy storage and more than 2.1GW of solar and wind power by 2040.
According to an annual ranking report released by IHS Markit recently, Powin Energy will become the fifth largest battery energy storage system integrator in the world in 2021, after Fluence, NextEra Energy Resources, Tesla and Wärtsilä. company.
