The US state of New York has proposed a framework to achieve 6GW/20.9GWh of energy storage by 2030. That would represent at least 20% of the peak electricity load of New York State, said Governor Kathy Hochul.
The plans, now before the Public Service Commission for consideration, propose 3GW/16GWh of new bulk storage, 1.5GW/4.5GWh of new retail storage and 200MW/400MWh of new residential storage. They are intended to help boost the adoption of renewable energy in the state.
If approved, the estimated storage expansion would reduce the projected future state-wide electric system costs by nearly $2 billion, the governor said in a statement. The plans were submitted by the New York State Energy Research and Development Authority (NYSERDA) and the New York State Department of Public Service (DPS).
The plans propose overall procurement 4.7GW of new storage projects across the state:
- Large-scale storage would top 3GW/16GWh, enough to power a million homes for four hours
- 1.5GW/4.5GWh of retail storage, enough to power 500,000 homes for up to four hours
- 200MW/400MWh of new residential storage to power 120,000 homes for up to two hours.
The state already has 1.3GW of existing energy storage under contract and moving towards commercial operation. These additional procurements will allow the state to achieve the 6GW goal by 2030, Hochul said.
Dr William Acker, Executive Director of the New York Battery and Energy Storage Technology Consortium (NY-BEST) said: “The new energy storage roadmap … recognises the critical role for energy storage in meeting our climate goals and enabling an emissions-free electric grid and puts New York on a path to deploying 6GW of energy storage by 2030, reinforcing New York’s position as a global leader in energy storage and growing clean energy jobs in the state.”
The plans continue to prioritise investment in research and development into long-duration energy storage technologies.
Electric utilities would also be required to study the potential of high-value energy storage projects towards providing cost-effective transmission and distribution services not currently available through existing markets.
The plans are available for public comment on the DPS website. A decision is expected in 2023.
