Electricity providers recently spoke out against the Biden administration’s attack on the fossil fuel industry, specifically power plants, warning that the speed at which officials are pursuing a “green energy transition” risks significant energy shortage.

According to a report from The Washington Times, Southwest Power Pool’s executive vice president, Lanny Nickell, recently said that, though he’s not advocating Biden “double down” on conventional energy sources, he does think the US needs to “slow down” with stripping “assets from our [energy] footprint.”

Lanny’s company oversees power grids across 14 states, including Kansas and Oklahoma, and portions of New Mexico, Texas, Arkansas, Louisiana, Missouri, South Dakota, North Dakota, Montana, Minnesota, Iowa, Wyoming, and Nebraska,

Tri-State Generation and Transmission’s Barry Ingold gave a similar cautionary statement about the fossil phaseout, pleading for a “balanced portfolio.”
