Athens is a town in Greene County, New York, United States.

The eastern town line is defined by the Hudson River and is the border of Columbia County.

U.S. Route 9W and the New York State Thruway (Interstate 87) pass through the town.

Pursuant to Article X of the Public Service Law, Athens Generating Company, L.P. (now operating as New Athens Generating Company, LLC) was granted a Certificate of Environmental Compatibility and Public Need for a 1,080-megawatt (MW) combined cycle natural gas powered plant in 2000.

It is located on a 150-acre area that was zoned as light industrial, to the west of the Village of Athens.

It was noted in a recent declaratory ruling that Con Edison has a bilateral agreement with New Athens Generating Company whereby Con Edison buys the plant's output and sells it in the NYISO wholesale market.

[11] A High Voltage Direct Current underground transmission line was proposed in an Article VII filing with the Public Service Commission in 2013.

Its northern converter station would have been located adjacent to the New Athens Generating facility.

The certification process was placed in limbo after the real estate for its planned southern converter station near the Indian Point Energy Center was sold in private auction from Con Edison to the Town of Cortlandt.
