Joint Powers Agency (JPA)
An entity formed pursuant to Government Code Section 6500 et seq. to allow government agencies to act jointly within the electric utility industry. Joint Powers Agencies have been typically formed for the purposes of owning, constructing, or operating electric power generating plants or transmission facilities that were either too large or too costly for a single agency to perform by itself.

Kilovolt (kV)
Unit of measurement of electromotive force equal to 1,000 volts. A volt is the force required to produce a current of one ampere through a resistance of one ohm.

Kilowatt (kW)
