NYPA begins construction on large-scale energy storage project


The New York Power Authority (NYPA) announced the start of construction on a large-scale, 20 MW energy battery storage project in northern New York.

The plant, located in Franklin County at the top of the state, will advance progress toward achieving New York’s ambitious target to have 3,000 MW of energy storage deployed by 2030 – the equivalent of powering 40 percent of New York’s homes.

The total estimated project cost is $29.8 million.

The battery storage facility, which is located in Chateaugay, adjacent to an existing NYPA substation, will be the second of its kind in New York State  – the only battery storage project that is New York State owned and operated – and among the largest such facilities in the country.

The project will include a unique one-hour lithium-ion battery system that will help New York State meet its peak power needs by absorbing excess generation that can be discharged later, based upon the changing needs of the grid.

The work is being undertaken by O’Connell Electric Co. in Ontario County in the Finger Lakes region. The firm was awarded a three-year engineering, procurement and construction contract in the amount of $22.6 million.

The project is expected to be in service early next year.
