Top House Democrats’ plan to eliminate carbon emissions from the power sector by 2035 includes a provision that would delay requirements to purchase more clean electricity if compliance costs become too high.

The provision, which has been called a “decelerator,” is tucked into the clean electricity standard top Democrats on the House Energy and Commerce Committee proposed in sweeping climate legislation last month. It could serve as an olive branch to the utility industry, which has raised concerns companies wouldn’t be able to meet a 2035 timeline.
