Three questions left open by Trump’s bulk power executive order

President Trump signed an executive order declaring a national emergency over foreign-made equipment in the country's bulk power system, the large-scale network of transformers, generators, and other gear that moves electricity across the grid. The order lets the Department of Energy block new purchases of certain equipment from around two dozen countries, though nearly all of the affected imports trace back to China. It also gives DOE power to force utilities to remove equipment that's already installed. The agency has four months to write rules spelling out exactly which products, companies, and situations are covered.

For most homeowners, this is grid-level policy rather than something that changes your own equipment or rebates. But it touches issues that shape electricity reliability and cost. Battery storage is one area of concern, since China dominates the supply of lithium batteries and the U.S. doesn't yet make enough domestically to replace them. Transformers are another: the country is already in a years-long transformer shortage that has slowed new power hookups, and Chinese transformer imports have quadrupled since 2023 as data center demand has grown. If DOE takes a strict approach and forces removal of already-installed batteries or transformers, analysts warn that could tighten supply further and worsen the shortage.

It's also unclear whether the order even applies to the power equipment serving data centers, since that gear typically sits below the "bulk power" threshold the order targets. Nothing changes immediately — the real impact depends on how DOE writes the rules in the coming months.
