The missing piece, the Port Authority and city claimed, was discounted electricity from Con Edison, because the standard rate for the juice is too high to justify turning off the diesel engines in favor of plugging in.
But the state Public Service Commission, which regulates utilities, nixed the so-called “shore power” idea on jurisdictional grounds in April, telling the Port Authority and the city to negotiate instead with the New York Power Authority, the port agency’s main supplier of electricity.
If I read the article correctly, there is still hope. It's a matter of working with the Power Authority to make this happen. It looks like the City and Port Authority were barking up the wrong tree - but this isn't over yet. Reducing the emissions from these ships should be a top priority.
