According to the US Energy Storage Monitor Report by Wood Mackenzie—a UK-based research and consultancy group, and US Energy Storage Association (ESA)—a national trade association backed by various storage-related government departments, the US brought 2,156 MWh of new energy storage systems online in the fourth quarter (Q4) of 2020, a new record for storage with an increase of 182 per cent over the third quarter (Q3).
Residential storage projects made up 14 per cent of the total installations for Q4, with 90.1 MW deployed. After gradual growth in deployments over the first three quarters of 2020, Q4 saw a notable residential spike driven largely by homeowner interest in California. Massachusetts led the non-residential segment in Q4, deploying 76.5 MWh of energy storage.
As prices fall and barriers to storage deployment are eroding, front-of-the-meter (FTM) storage is taking off in the country. The segment contributed 529 MW out of the total 651 MW of storage deployed in Q4.
In 2020 overall, 1,464 MW/3,487 MWh of new storage came online in the US.
