District of Columbia

Description: In February 2009, the District of Columbia Public Service Commission (DCPSC) adopted interconnection regulations that apply to systems up to 10 MW that are operated in parallel with the electric distribution system and not subject to the interconnection requirements of PJM. Four tiers are laid out with various criteria systems seeking to interconnect. IEEE 1547 is generally used as a technical standard for evaluation. External disconnect switches are not required for systems below 10 kW, but are required for all other systems. Systems larger than 1 MW require liability insurance.
