|Power Supply Business Unit|
The primary objective of the (PSBU) is to provide Pasadenas customers with safe, reliable and high-quality electrical energy at the lowest possible price, and fully utilize all city-owned resources to maximize wholesale revenues.
Most of Pasadenas electricity is supplied by the PSBU through long-term energy supply contracts and short-term purchases from the wholesale power market. The balance of the electricity is generated locally using natural gas and hydroelectric generating units. To see what power sources currently comprise the PWP power mix, check out the latest Power Content Label to see the percentages.
The PSBU also sells surplus energy, transmission, ancillary services and natural gas to wholesale customers outside Pasadena to generate revenues and optimize its energy portfolio. Other portfolio management activities include active participation in joint project committees to control the cost of Pasadenas external resources.
PSBU provides the ancillary services necessary to deliver energy, such as
operating reserves, load balancing capability, voltage support, and
self-start capability. These
services are also provided to the California Independent System Operator
