New York can’t buy its way out of blackouts, by David Wojick

As the politicians push for ever more “renewable” energy and electric cars, it’s become ever more apparent that their numbers aren’t going to add up. From David Wojick at wattsupwiththat.com:

New York City will soon be home to the world’s biggest utility-scale battery system, designed to back up its growing reliance on intermittent renewables. At 400 MWh this batch of batteries will be more than triple the 129 MWh world leader in Australia.

The City of New York’s director of sustainability (I am not making this title up), Mark Chambers, is ecstatic, bragging: “Expanding battery storage is a critical part of how we advance momentum to confront the climate emergency while meeting the energy needs of all New Yorkers. Today’s announcement demonstrates how we can deliver this need at significant scale.” (Emphasis added)

In reality the scale here is incredibly insignificant.

In the same nonsensical way, Tim Cawley, the president of Con Edison, New York’s power utility, gushes thus: “Utility scale battery storage will play a vital role in New Yorks clean energy future, especially in New York City where it will help to maximize the benefit of the wind power being developed offshore.”

This puts the Con in Con Edison.

Here is the reality when it comes to the scale needed to reliably back up intermittent renewables. For simplicity let us suppose New York City is 100% wind powered. Including solar in the generating mix makes it more complicated but does not change the unhappy outcome very much.

NYC presently peaks at around 32,000 MW needed to keep the lights on. If Mr. Biden makes all the cars and trucks electric it might be closer to 50,000 MW but let’s stick to reality.

This peak occurs during summer heat waves which are caused by stagnant high pressure systems called Bermuda highs. These highs often last for a week and because they are stagnant there is no wind power generation. Wind turbines require something like sustained winds of 10 mph to move the blades and more like a whistling 30 mph to generate full power. During a Bermuda high folks are happy to get the occasional 5 mph breeze. These huge highs cover many states so it is not like we can get the juice from next door.
