AV Clearview Transimission Project

The AV Clearview Transmission Project (the Project) is being jointly developed by Critical Path Transmission, Exelon Transmission and Powerlink. Located in California’s Antelope Valley region, the Project spans Kern, San Bernardino and Los Angeles counties and provides electricity consumers with low cost access to renewable resources such as solar and wind generation.

The Project was originally proposed to the California ISO (CAISO) as an economically efficient resource for the 2010-2011 Transmission Planning Process (TPP). Since then, the Project has evolved as a policy / reliability alternative in subsequent TPPs and is now an alternative to generation interconnection upgrades needed in the South of Kramer zone.

The Project will interconnect three critical points in the western Mojave region of the CAISO grid – Southern California Edison’s (SCE) existing Windhub and Kramer substations and a new substation, Yeager, to be built on the northwest corner of the Edwards Air Force Base (EAFB). Current designs of the Project include approximately 20 miles of new, double circuit 500 kV transmission line and 20 miles of new, double circuit 230 kV transmission line.

The design and routing of AV Clearview incorporates four years of collaboration with stakeholders and permitting agencies, including:

There are many compelling reasons for this transmission upgrade with the Project being:

  • Congestion relief along Path 26, permitting the deliverability of more than 1,370 MWe of renewable generation (hydroelectric, solar and wind);

  • Congestion relief at Southern California Edison’s (SCE) Kramer substation by allowing power to bypass the Kramer-Lugo line and flow through the Antelope Valley onto SCE’s Vincent-Lugo line;
  • A provider of critical operational flexibility to the CAISO allowing the shifting of power flows to balance wind generation in the Tehachapi area with the solar generation in the Mojave Desert and Kramer/Barstow region;

  • A provider of energy security and mission readiness for EAFB;

  • A public-private venture, ensuring financial accountability, environmental sensitivity, and responsiveness to the local community; and,

  • A low cost way to deliver renewable energy to the grid from a large CREZ zone (according to the California Energy Commission’s RETI Phase 2 Final Report), saving customers $200 million per year over competing proposals in the area.

  • The project currently is in the permitting phase. Construction on the project is expected to start in 2016, with the project completed in 2018.
