The Architect of the Capitol's (AOC) Capitol Power Plant jurisdiction manages year-round power plant operations — providing and distributing steam and chilled water to heat and cool the 23 facilities around the Capitol campus. The jurisdiction also maintains an administration building and the utility tunnel distribution and metering system.

The Capitol Power Plant operates on a reimbursable basis to non-congressional facilities and procures electricity from commercial suppliers. In support of the AOC's long-term energy program, the Capitol Power Plant is the site of the newly constructed Cogeneration Plant and the multiphased Refrigeration Plant Revitalization construction project.
