long exposure of the Ravenswood power plant as seen looking east from Roosevelt Island.
This is the largest power plant in all of New York State. It used to be part of New York’s ConEdison before generation was deregulated and the plant was sold off to Keyspan and then TransCanada. It’s located in Long Island City just east of Roosevelt Island and is one of the primary sources of electrical generation for Manhattan with a nameplate capacity of about 2 gigawatts.
It has 4 primary gas fired generators and a number of smaller secondary gas fired generators. The 4 big boys are monstrous. The largest being the 1 gigawatt “Big Allis” or Generator 30 (named after the manufacturer Allis Chalmers). It has two sisters, Generators 10 & 20. All 3 are single cycle gas fired generators. Natural gas is burned, it heats up an air/water mixture, the pressurized steam drives the rotation of a magnet, and this creates electricity.
Smoke stacks from left to right are 40 (not shown), 30, 20, 10. You can see a massive conveyor belt complex in front that goes off the frame, that used to transport coal from river barges when it was first built. The plant upgraded to burning relatively clean natural gas in the 60s. The coal apparatus remains.
