Former Con Edison Manufactured Gas Plants

We’re working closely with the New York State Department of Environmental Conservation and the New York State Department of Health to test and remediate, where appropriate, sites that many years ago were home to manufactured gas plants.


Operating from the early 1800s to mid-1900s, these plants used whale oil, rosin, coal, or a mixture of coal, oil, and water, to produce a gas that could be distributed and used as fuel. However, some of the byproducts of gas production, such as coal tar (oily waste containing chemicals) are potentially hazardous to human health and the environment.

There are approximately 300 former manufactured gas plants in New York State, and 51 of these New York sites are on properties we own or used to own.

We’ve been investigating and remediating many of these sites, working with experienced independent experts as well as state and local agencies. We also make sure to quickly address any concerns of residents and business owners who may be affected.
