One Big Beautiful Bill Act Impact on U.S. Power Grid

planned

The One Big Beautiful Bill Act is a legislative proposal that would end federal clean energy incentives in the United States. This would drastically reduce the rate of new clean energy additions to the U.S. power grid, potentially slashing it to as little as 13 GW per year over the next decade. The act threatens to eliminate up to 72 percent of all new clean electricity capacity that would have been built under current law by 2035, reducing overall energy additions to the grid by at least 50 percent. The act would also impact nuclear power capacity additions and limit the replacement of lost clean energy capacity with new natural gas or other energy sources.
