The levelized cost of storing electricity depends highly on storage type and purpose; as subsecond-scale frequency regulation, minute/hour-scale peaker plants, or day/week-scale season storage. Using battery storage is said to have a levelized cost of $120 to $170 per MWh. This compares with open cycle gas turbines which, as of 2020, have a cost of around $151–198 per MWh.
