COST ANALYSIS OF DISTRIBUTED STORAGE IN AC AND DC
Major projects now deploy clusters of 20+ containers creating storage farms with 100+MWh capacity at costs below $280/kWh. Technological advancements are dramatically improving
The 2020 Cost and Performance Assessment provided installed costs for six energy storage technologies: lithium-ion (Li-ion) batteries, lead-acid batteries, vanadium redox flow batteries, pumped storage hydro, compressed-air energy storage, and hydrogen energy storage.
Pumped storage hydropower (PSH) plants are a sizable part of the energy mix in the U.S., with 40 PSH plants in operation in 2015, totaling about 22 GW in installed capacity (DOE 2016) and an estimated 553 GWh of energy storage (Uria-Martinez et al. 2021).
Cost metrics are approached from the viewpoint of the final downstream entity in the energy storage project, ultimately representing the final project cost. This framework helps eliminate current inconsistencies associated with specific cost categories (e.g., energy storage racks vs. energy storage modules).
Non-battery systems, on the other hand, range considerably more depending on duration. Looking at 100 MW systems, at a 2-hour duration, gravity-based energy storage is estimated to be over $1,100/kWh but drops to approximately $200/kWh at 100 hours.
