PJM Interconnection LLC unveiled a reliability plan hours after top officials in the Trump administration called on the operator of the largest US power grid to do more to bolster the network and help tame electricity prices as demand from data centers booms.

Late Friday, the grid’s board proposed an “immediate initiation” of backstop plans to secure more power supplies after its auction in December failed to meet standards aimed at preventing blackouts. The proposal will be filed to the Federal Energy Regulatory Commission for approval.
