A bill pending with Governor Kathy Hochul could shape how much New Yorkers pay for renewable energy for years to come — but she only has a few days left to sign it and deliver the full savings promised, the bill’s supporters say.

Wind and solar developers have until Thursday, December 4, to bid for state contracts under an expedited timeline Hochul announced in September. It may be the last chance for the companies to secure contracts in time to build projects with federal tax credits, which they’ve relied on for decades and which are set to expire next year under legislation signed by President Donald Trump.

When developers submit a bid, they have to include an estimate of how much a project will cost to build and operate over the long term, including land, materials, financing, and property taxes. The lower the cost, the more likely it is that the state will approve the bid — and the less it will cost New Yorkers whose energy bills pay for the project.

When New York abruptly backed down this month from its plans to implement a nation-leading ban on gas in new buildings, some legal observers had questions.

Lawmakers passed the All-Electric Buildings Act, which requires most new buildings to have only electric appliances, in 2023 as a step toward reducing pollution from the state’s largest source of greenhouse gas emissions and advancing New York’s legally mandated emissions targets. It was set to take effect in January.
