The DEQ Small Energy Storage Permit by Rule regulation requires DEQ to create a permit-by-rule (PBR) for energy storage projects with a rated capacity not exceeding 150 MW.

A Small Energy Storage Facility is defined in DEQ regulation 9VAC15-100-10 as an energy storage facility that uses electrochemical cells to convert chemical energy with a rated power capacity not exceeding 150 megawatts in alternating current (150 MW/AC). The State Corporation Commission (SCC) defines energy storage as: “any technology that is capable of absorbing energy, storing that energy for a period of time, and re-delivering that energy after storage.” 

Below, DEQ aims to provide navigable information for anyone seeking to understand the energy storage permitting process.
