LOL, history is repeating itself here.
If you want to know what fallout (sorry) will come from a major nuclear power plant closure, just look at what happened 25+ years ago when Andrew Cuomo's father Mario Cuomo was the governor of NY state, and pushed agreements to shut down Long Island's brand sparkling new Shoreham nuclear power plant.

The electricity customers on Long Island got hosed on that one, and instead of getting cheaper electricity rates from the nuclear plant , they have paid some of the highest rates in the country for the past 25 years.

The school district where the Long Island plant was located, which used to be one of the best school districts in the whole country also got hosed when they lost a major source of school tax revenue.

There are a lot of reasons why Mario Cuomo was eventually voted out of the NY governor's office, but the anger of many Long Islanders over the forced Shoreham nuclear plant shut down was part of it. I'm surprised our current governor does not think that the Indian Point shutdown will have a similar political blowback to his political career..
Also, Is it really a good idea to switch a major portion of NYC's energy supply to come from a 333 mile long electric line from Quebec, Canada???
