Tucson Electric Power Activates 2.4-Megawatt Solar Array

The Western Hemisphere's largest solar photovoltaic power system is now pumping out power near Springerville, Arizona. Tucson Electric Power (TEP) continues to follow through on its plans to expand the Springerville Generating Station Solar System, which now has a peak generating capacity of 2.4 megawatts. TEP plans to expand the system to 4 megawatts by 2004. Currently, the world's largest photovoltaic system is a 3.3-megawatt installation in Serre, Italy, although larger systems are now being planned throughout the world. See the TEP press release.

The TEP installation is rivaling another solar power system being built in Arizona by APS. As reported in the November 6th edition of the EREN Network News, APS hopes to expand its Prescott Airport Solar Power Plant to 5 megawatts within the next five years.

Spire Corporation is providing much smaller solar power systems to 12 homes in the Chicago metropolitan area. The company's Spire Solar Chicago operation will install 1.2-kilowatt systems on single-family homes in an affordable housing development in southeastern Chicago. The systems should provide about one-quarter of the electricity needs for the energy-efficient homes. See the Spire press release.
