Rising power bills in PJM, which operates the grid covering 13 states and the District of Columbia, or one in five Americans, have led to a political backlash over the last year and threats by some governors to abandon the regional grid. PJM’s territory holds the largest concentration of energy-intensive data centers in the world. Capacity payments, which are made to power plant operators to guarantee they run during periods of spiking demand to avoid blackouts, are a piece of power bills in the region. PJM is governed by a board of managers, and its voting members include transmission line owners and independent power plant operators. While states are not given a vote, they have wielded their power over PJM in other ways.
