Developers of new onshore wind, solar and other renewable energy projects in the US will have extra time to complete construction and qualify for federal tax credits, a move aimed at helping the companies overcome Covid-related delays and disruptions, the Internal Revenue Service (IRS) has announced.

Under Notice 2021-41, projects where construction began between 2016-2019 will have “one or two years” more to finish than the previously stipulated four or five years, according to the IRS while those with a 2020 construction start will have five years, up from four.
