Natural Gas Main Replacement

National Grid crews will be installing new gas mains in several Long Island communities, making clean-burning natural gas available to more homes and businesses in the area.

A message from John Bruckner, President, National Grid, New York:

“We hope these pages help you understand the scope and detail of our natural gas main replacement program on Long Island. Our goal is to modernize our network to make it even more reliable than it is today. A robust natural gas system provides a brighter economic and environmental future by supporting the growth of electric vehicles, wind, solar and other renewable technologies while also delivering lower-carbon heating. Please let us know if you have any questions on our program by contacting us at"
