History & Asbestos Use
Ravenswood Generating Station was built by Consolidated Edison between 1963 and 1965 with three large steam-generating units burning oil and natural gas. A fourth unit, known as "Big Allis," was one of the largest steam turbines in the world when installed. The plant was constructed with extensive asbestos-containing insulation throughout its boilers, turbines, and piping systems, standard for power plants of that era. The facility has since passed through operators including KeySpan and is currently owned by Rise Light & Power.
