New York University's core campus area near Washington Square Park stayed warm and lit while much of the rest of lower Manhattan was blacked-out during Hurricane Sandy.
How did NYU manage to do that?
It has a cogeneration network, which burns natural gas in a unit that both makes electricity and delivers heat, reports Matthew L. Wald at The New York Times.
The cogen system doesn't cover the entire campus — just NYU's larger buildings at the core of the campus near Washington Square.
It had to isolate itself from Con Edison's network, effectively putting the campus' power grid on an island.
Unfortunately, the system doesn't cover the NYU Langone Medical Center, which made headlines and drew criticism when its backup generator failed and it had to evacuate all of its patients to nearby hospitals.
