Grid Scale Energy Storage Market

Grid-scale energy storage is the keystone technology of a high-renewables grid. The market is bifurcating clearly: Lithium-ion BESS dominates the 2 to 4 hour duration segment for frequency regulation and peak capacity, while a new generation of Long Duration Energy Storage (LDES) technologies including iron-air, flow batteries, and compressed air are competing to solve the multi-day wind and solar drought challenge. Understanding how to stack revenues across ancillary services, capacity markets, and energy arbitrage is critical to getting the asset valuation right.
