GTM Research reports that 18.3 MW of energy storage was deployed in Q1 2016, which is a decrease of 84% from Q4 2015 but an increase of 127% from Q1 2015.
That was the lead finding in GTM’s latest U.S. Energy Storage Monitor. a collaboration between GTM Research and the Energy Storage Association (ESA).
The figures indicate that 21.2 MWh of energy storage were deployed in the first quarter of 2016.
“The ratio of energy (MWh) to power (MW) is higher for behind-the-meter market segments than for front-of-meter segments because the majority of front-of-the-meter systems have historically been deployed for frequency regulation, a short-duration application,” GTM says in the publication. “As a result, the behind-the-meter segment made up 80% of the total MWh deployed in Q1 2016.”
GTM notes that the PJM Interconnection (excluding New Jersey) and California account for the majority of U.S. energy storage deployments (92% combined market share).
The GTM report noted that the U.S. Senate passed Grid Modernization Act of 2016, though it still must be reconciled with HR 8. The Federal Energy Regulatory Commission (FERC) issued a notice to hold a technical conference to discuss interconnection requirements; also initiated AD16-20 to allow ISOs the opportunity to provide data on energy storage participation in existing markets.
Various states – including Hawaii, California, Nevada, Colorado and New York – are either studying or going forward with some manner of energy storage development plans.
Also the Midcontinent ISO (MISO) held an energy storage workshop and classified priorities into three phases. Various states, such as Virginia, have had energy storage legislation tabled until the future.
