Committed to long-term ownership and acquisition of transmission assets, BHE U.S. Transmission builds upon the significant operational and ownership experience gained by Berkshire Hathaway Energy through its businesses' ownership of existing electric transmission systems. BHE U.S. Transmission draws upon this experience to develop cost-effective, reliable transmission solutions for wholesale customers.
BHE U.S. Transmission's delivery team has developed approximately $1.6 billion of transmission projects at voltages of 345 kilovolts and higher and has extensive experience in traditional utility and stand-alone transmission project development.
BHE U.S. Transmission indirectly owns a 50% interest in ETT, along with subsidiaries of American Electric Power Company, Inc. ("AEP"). ETT owns and operates electric transmission assets in the ERCOT and, as of December 31, 2016, had total assets of $2.9 billion. ETT is regulated by the Public Utility Commission of Texas. A total of $2.7 billion of transmission projects were in-service as of December 31, 2016, with $0.3 billion of projects forecast to be completed in 2017 through 2020. ETT's transmission system includes approximately 1,235 line miles of transmission and 34 substations as of December 31, 2016.
In 2013, BHE U.S. Transmission submitted a joint proposal with Pacific Gas and Electric Company into the California ISO's competitive transmission process to develop, construct and own the Central Valley Power Connect transmission project in California. This will be a double-circuit 230 kilovolt transmission line and will extend approximately 60 miles from the Gates substation in Fresno County to the Gregg substation in Madera County. The project was awarded in November 2013 with a projected in-service date of April 2020. However, given subsequent assumptions regarding load growth and renewables integration, the California ISO is re-studying the line in its 2017-2018 planning cycle.
BHE U.S. Transmission indirectly owns a 25% interest in Prairie Wind Transmission, LLC, a joint venture with AEP and Westar Energy, Inc., to build, own and operate a 108-mile, 345 kV transmission project in Kansas. The project cost $158 million and was fully placed in-service in November 2014.In 2014, BHE U.S. Transmission formed TransCanyon LLC, a joint venture with Bright Canyon Energy, a newly formed subsidiary of Pinnacle West Capital Corporation. TransCanyon LLC's purpose is to identify, develop, own and construct electric transmission projects located in the 11 western states comprising the Western Electricity Coordinating Council footprint.
In March 2016, TransCanyon formed a strategic alliance with Pacific Gas & Electric Company to jointly develop transmission opportunities in the California ISO footprint.
In 2015, BHE U.S. Transmission formed multiple joint venture entities with a subsidiary of Westar Energy, Inc. These companies identify, develop, own and construct electric transmission projects located in the Southwest Power Pool and Midcontinent Independent System Operator footprints.
BHE U.S. Transmission continues to evaluate development opportunities in evolving competitive markets either through joint ventures or on a stand-alone basis.
BHE U.S. Transmission has partnered with major entities to own and operate assets in the western U.S. and is exploring opportunities to expand.
