Note: Categories reflect whether a state compels storage. Michigan is only partly inside PJM and meets its statutory storage target through MISO utilities. Lead-state figures are transmission-level storage targets, shown as a range where the upper volume has not yet been assigned to a track; distribution and behind-the-meter volume is excluded. Data as of June 2026.
