(Western Energy Supply and Transmission Associates)
In the mid 1970's Southern California Edison (SCE) submitted a proposal to Western Energy Supply and Transmission
(WEST) Associates to expand the solar monitoring effort outside of the SCE service territory in ann effort to
establish an accurate solar data base. The project, as approved, created the WEST Solar Monitoring network which
eventually included 52 stations in six western states (Arizona, California, Colorado, Nevada, New Mexico and
Wyoming). The network operated for five years during 1976-1980 collecting 15-minute global horizontal
and direct normal solar irradiances, and dry-bulb temperatures. Not all stations were in operation all five
years, nor did all stations collect all three data parameters.
