Research firm Wood Mackenzie has downgraded its forecasts for US demand for energy storage in 2022 and 2023 by around one-third, in its most recent global outlook report.
Some 5GWh of utility-scale battery energy storage was deployed in the first half of 2022, up one third while wind and solar fell 50-70%, according to American Clean Power (ACP).
Battery storage deployments on the California ISO (CAISO) grid slowed in the lead-up to the peak summer season, with no new battery energy storage connected in May and only 65MW added in June.
