This week has brought news of at least another 1.4 GWh of battery energy storage capacity in the United States, with utility Georgia Power starting construction on an 800 MWh site, Recurrent Energy securing finance for a 600 MWh project, and Redwood Materials reporting a $350 million funding round.
Atlanta-based Georgia Power yesterday announced the start of construction at its 200 MW/800 MWh BESS in Twiggs County, southeast of Macon, Georgia.
The utility will own the BESS, which is being built next to the Twiggs County Solar project by North Carolina-based construction company Crowder Industrial Construction, LLP.
Georgia Power said the BESS was selected via a tender as a result of its Integrated Resource Plan Update in 2023 and was approved by the Georgia Public Service Commission (PSC) last month.
The utility said it is already constructing the 49.5 MW Moody BESS in Lowndes County, near the Moody Air Force Base solar site, which is due in May; the 128 MW Robbins BESS, near the Robbins Air Force Base solar site in Bibb County, due June; the 530 MW phases I and II of its McGrau Ford BESS in Cherokee County, due October 2026 and September, respectively; and the 57.5 MW Hammond BESS on the retired Plant Hammond coal-fired power station site in Floyd County, due November next year.
The electric company is seeking Georgia PSC approval for more than 3.02 GW of energy storage capacity across 10 BESS and a further 350 MW of BESS project capacity at two solar-plus-storage sites and says it will tender for a further 500 MW of BESS with at least two hours of storage capacity. Bids will be due in that tender in “early 2026” with the projects to be delivered before 2032, the utility said.
Arizona
Out west, the Recurrent Energy business owned by Canadian Solar on Tuesday announced an $825 million finance package for energy storage and solar projects in Maricopa County, Arizona.
The construction finance loans and tax equity commitment will fund the under-construction, 600 MWh Desert Bloom Storage site and the 150 MW (AC) Papago Solar project. Recurrent did not separate out funding details for the separate facilities.
Both sites are due online before July and are being developed as part of a multi-project deal signed by Recurrent and utility Arizona Public Service (APS). They follow construction of the 1.2 GWh Papago Storage site which began operating in Maricopa County in July, under a 20-year “tolling agreement” with APS, by which the utility operates the site for the contract term.
Recurrent said German public lender Norddeutsche Landesbank Girozentrale; Japan’s Mitsubishi UFJ Financial Group, Inc.; US rural banking network CoBank; and Germany’s Siemens Financial Services provided the construction finance element of the funding package. US banking giant Wells Fargo provided the tax equity commitment.
Dallas-based Primoris Services Corp. is providing engineering, procurement, and construction services for the Desert Bloom Storage site, Recurrent said.
More BESS?
And there could be more BESS on the way courtesy of Redwood’s latest funding round.
The Nevada-based company develops BESS, makes battery components, and produces critical raw materials cobalt, nickel, copper, lithium and cathode active material. Announcing the results of the Series E funding round yesterday, Redwood said the $350 million would be injected across its operations.
Stating its BESS can also be used to optimize electricity supply from natural gas turbines and nuclear, a press release issued by Redwood about the funding round said, “By combining deep materials and manufacturing expertise with advanced power electronics and software, Redwood is creating a new generation of US-made energy storage systems … reducing reliance on imported LFP [lithium iron phosphate] batteries.”
The funding round was led by Californian venture capital (VC) and private equity investor Eclipse Ventures and included the NVentures VC arm of Californian chipmaker Nvidia
