Storage, EV and stamps

Battery storage

Maryland Energy Storage Supplemental Form submitted with the interconnection application: stand-alone vs. paired, shared inverter, whether it can charge from the grid (and how prevented), kW AC/kWh, operating intent (offset load/non-export, net meter, wholesale, backup), lockable visible AC disconnect, one-line diagram.

Common issues the utility lists

  • Certificate of Completion system size differs from application size (final size may be smaller, never larger) - submit modified application
  • Missing county electrical inspection certificate
  • Unpaid funds due to BGE

Gridpol’s pre-submission check covers these before we file.
