Peak Energy says that it will use passively cooled grid-scale storage to deploy the first sodium-ion battery in the Midcontinent Independent System Operator (MISO) service area with RWE Americas in eastern Wisconsin. This storage cuts auxiliary power use by 90% and lifetime storage costs by $70/kWh.
Thanks to a joint pilot project between Peak Energy and RWE Americas, the Midcontinent Independent System Operator (MISO) will get its first sodium-ion battery. The project comes just eight months after Peak Energy installed the biggest sodium-ion storage system on the grid in the US.
Peak Energy’s passively cooled, grid-scale energy storage system is set to be used in Eastern Wisconsin. It could be the first sign that MISO is moving away from lithium-based storage as the grid operator faces capacity limits, rising costs, and solar project cancellations that some industry experts think could slow battery deployment.
