Peak Energy and RWE Americas to deploy first sodium-ion battery in MISO

The project is a dual pilot project. The system is passively cooled and grid-scale. It is designed to operate safely at wide temperature ranges and reduce lifetime energy storage costs. Peak systems are designed to reduce overbuild, require less routine maintenance, and waste less energy, cutting 90% of auxiliary power use. The proprietary ESS can reduce the lifetime cost of energy stored by an average of $70/kWh. Using Peak’s systems could cut total storage system costs down another 25% compared to lithium-ion options. Quote: "The Midcontinent Independent System Operator (MISO) will receive its first sodium-ion battery thanks to a dual pilot project from battery company Peak Energy and global energy company RWE Americas." Quote: "Set to be deployed in Eastern Wisconsin, Peak’s passively cooled, grid-scale energy storage system could be the first ripple indicating MISO’s pivot toward next-gen, non-lithium storage..." Quote: "Sodium-ion cells are particularly well-suited for the Midwest, given that they can operate safely at wide temperature ranges without negative impacts on performance." Quote: "By integrating passive cooling and prioritizing low degradation designs, Peak systems should reduce overbuild, require less routine maintenance and waste less energy, to the tune of cutting 90% of auxiliary power use." Quote: "According to the company, their proprietary ESS can reduce the lifetime cost of energy stored by an average of $70/kWh, which is around half the total price of an average battery system today." Quote: "Doing it with Peak’s systems could cut the total storage system costs down another 25% compared to lithium-ion options."
