New York City doesn’t have enough available energy to meet the needs of a serious heat wave or an especially frigid winter.

The city is now relying almost nonstop on two aging emergency electric power-supply barges off Brooklyn’s Sunset Park to keep the lights on and apartments cool, Crain’s reports.

In other words, Gotham is already relying on its last line of defense against blackouts, and at high risk of catastrophic failure.

If these aging stations fail, or demand spikes in, say, a week of 100-degree-plus temps, we’re in big trouble.

Blame Albany Democrats — Gov. Kathy Hochul and our feckless state Legislature. 

Under then-Gov. Andrew Cuomo, Albany rushed to close the Indian Point nuclear plant, choke off new supplies of natural gas and retire fossil-fuel power plants far faster than alternative sources could come online — while simultaneously booting electricity demand by pushing shifts to electric cars, heating and so on.

And Hochul only recently began even talking about slowing down the madness.

The insane state Climate Action Plan closes reliable natural-gas power plants, aiming to replace them with expensive and less reliable solar and offshore wind farms as well as massive battery-storage facilities.

And the alternatives aren’t getting built anywhere near as fast as the plan requires.

New York’s oldest-in-America power infrastructure needs immediate improvements as experts warn that the system is operating near its limits.

Even if we dodge blackouts, we still suffer: New York households pay the third-highest residential electricity prices in the country, trailing only Hawaii and California, per the Empire Center’s Energy Data Bulletin.

NY prices in May were up 12% from a year earlier, rising at twice the US average.

California is the only large state with higher residential electricity prices, thanks to similar-but-worse “climate” policies.

The politicians will rush to blame Con Edison and other utilities, but these companies have to do what Albany orders — no matter how insane.

Looming blackouts are an existential threat — and inevitable unless the state abandons its climate madness.
