Rise Light & Power, a unit of LS Power, said it plans to redevelop its 2,480 MW Ravenswood Generating Station – New York City’s largest power generator – as a renewable energy hub.

The industrial site in Long Island City, Queens, is planned to integrate offshore wind and upstate wind and solar into New York City’s electric grid.

The site redevelopment plan envisions multiple parts: offshore wind, upstate renewables, thermal energy by repurposing Ravenswood’s river water intake system to provide zero-emission thermal energy, and large-scale battery energy storage. The plant is currently fired primarily by No. 6 fuel oil and natural gas.

Ravenswood was originally built in 1963 and was owned by Consolidated Edison of New York. The first two units were Ravenswood 10 and 20, each with a generating capacity of around 385 MW. 

In 1965, Ravenswood 30 was commissioned with a generating capacity of nearly 981 MW. In the 1970s, multiple combustion turbine units were installed in simple cycle configuration to meet peak power demands. 

As deregulation moved through New York State, Con Edison was required to sell all of its in-city generating stations iincluding Ravenswood. In 1999, Con Edison transferred ownership to KeySpan Energy for around $600 million. In 2004, KeySpan built Ravenswood 40 a combined cycle unit with generating capacity of 250 MW.

National Grid plc acquired KeySpan in 2007 and was required to sell Ravenswood in a bid to ensure market competition . In August 2008, Ravenswood was sold by National Grid to TransCanada Corp. for $2.9 billion. Ravenswood later was sold to LS Power/Helix Energy Solutions Group.

Plans were announced in 2019 for a 316 MW battery storage system to be built at Ravenswood. 

Since its inception in 1990, LS Power has developed, constructed, managed or acquired more than 45,000 MW of power generation, including utility-scale solar, wind, hydro, natural gas-fired and battery energy storage projects. Additionally, it has developed over 660 miles of high voltage transmission
