PG&E, MidAmerican, Citizens Energy Corp. to develop transmission line

Pacific Gas and Electric Co. (PG&E), MidAmerican Transmission, LLC (MidAmerican Transmission) and Citizens Energy Corp. (Citizens Energy) have been chosen by the California Independent System Operator Corp. (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.

Approved by the ISO to address the growing power demand in the greater Fresno area, the new line will help reduce the number and duration of power outages, create jobs and support economic development, and bolster efforts to integrate renewable energy onto the grid. The transmission line would be operational no later than 2022, and could come on line earlier.

The ISO approved the project during its annual Transmission Planning Process in March. The ISO chose the consortium of PG&E, MidAmerican Transmission and Citizens Energy over four other qualified bidders in a competitive process. The project is the second to be approved under new ISO rules that require certain new transmission projects be subject to competition.

The project will need to undergo an approval process through the California Public Utilities Commission. PG&E, MidAmerican Transmission and Citizens Energy will work collaboratively with local stakeholders to determine the optimal routing of the line as part of the approval process.
