Not in my area.
LIPA's Port Jefferson facility is listed as Fuel Oil (No. 6), Natural Gas and Fuel Oil (No. 2) as the primary sources.
LIPA's Northport facility is listed as Natural Gas, and Fuel Oil (No. 2) as the primary sources.
Many other facilities in Long Island, Queens and Brooklyn are the same.
These are 2018 listings.
Natural gas is the main fuel on Long Island. LIPA *can* burn fuel oil, but it doesn’t. It’s generators were changed over to allow burning natural gas TWENTY-SIX YEARS ago. And if you’ve read any LIPS document printed since, they all presume natural-gas operation.
