Here’s an interesting alternative to battery storage that I’m seeing being increasingly common with solar farm installations. Looks like it will be installed about the same time that a coal plant in the same area gets shut down.
“The Columbia Energy Storage Project is the first long-duration energy storage project of its kind to be developed in the United States. The system’s unique features will boost grid stability and deliver enough electricity to power approximately 18,000 Wisconsin homes for 10 hours on a single charge.
Development of the Columbia Energy Storage Project is led by Alliant Energy in partnership with WEC Energy Group, Madison Gas and Electric, Shell Global Solutions US, Electric Power Research Institute, the University of Wisconsin–Madison and Madison College. Pending approval, the project will be built south of Portage, Wisconsin, in the town of Pacific, near the current Columbia Energy Center. Construction is expected to begin in 2026 and be completed by the end of 2027.”

Soooo 18MW / 180MWh? I’m sorry but that size is not impressive. Good MWh considering the size, but there are GW-size projects in FEED stages right now in the US.
180 MWh on 13 acres for $90 million actually sounds like a solid deal if they deliver, even with the reduction in RTE compared to lithium ion.
