Electric Transmission Texas (ETT) energized the last of seven 345-kV transmission line projects associated with the Competitive Renewable Energy Zones (CREZ) initiative in west Texas. The Edith Clarke to Cottonwood transmission line was energized to the Electric Reliability Council of Texas (ERCOT) grid on Dec. 4.
Pacific Gas and Electric (PG&E), MidAmerican Transmission and Citizens Energy were chosen by the California Independent System Operator (ISO) to develop, own and operate a new transmission line in the Central Valley region of California. The 230- kV line will span about 70 miles across Fresno, Madera and Kings counties, running from the Gates to Gregg substations, which are owned and operated by PG&E.
Cupertino Electric is installing a new 230-kV transmission line to interconnect a new substation serving a 200-MW photovoltaic power plant in Imperial Valley, Calif. When complete in late 2013, the overhead line will span five miles and interconnect a new 230-kV substation on the 2,000-acre solar project site in California’s Imperial Valley.
