RWE, Peak Energy to deploy first sodium-ion battery in U.S. grid
Peak Energy says it will deploy the first sodium-ion battery in the Midcontinent Independent System Operator (MISO) service area with RWE Americas in eastern Wisconsin, using passively cooled grid-scale storage that cuts auxiliary power use by 90% and lowers lifetime storage costs by $70/kWh.
Two approaches to prevent queue-jumping by thermal generation
A study from Grid Strategies and ACORE finds evidence that priority transmission access offered by three grid operators has yielded generating portfolios “heavily weighted” to thermal resources. The study favors transmission planning followed by recruitment of projects that can use planned transmission capacity to enter the interconnection queue. A limited non-discriminatory “fast path” could meet near-term reliability needs.
