The Public Service Commission of the District of Columbia was originally established by Congress in 1913 and was reaffirmed by Congress as an independent agency of the District of Columbia Government in the District of Columbia Home Rule Charter in 1973. The DCPSC functions as an independent, quasi-judicial agency in the District of Columbia Government. The mission of the PSC is to serve the public interest by ensuring that financially healthy electric, natural gas, and telecommunications companies provide safe, reliable, and quality services at reasonable rates for District of Columbia residential, business, and government customers.
