Overview of Western Energy Coordinating Counsel (WECC)

  • 170 + members

  • Members include utilities, independent power producers, consumers and regulators.

  • WECC has been a reliability council since the early 1970's

  • WECC activities typically address the High Voltage transmission system - > 138kV

Overview of WECC

  • Key WECC Functions

  • Electric Reliability - WECC coordinates, sets and maintains electric reliability standards in the west.  WECC expects to implement mandatory reliability standards that result from The Energy Policy Act

  • Determines and sets operating standards for the western interconnection

  • Conducts transmission system impact studies for the purpose of maintaining and improving electrical reliability

  • Funds and oversees three major reliability centers whose job is to work together to "keep the lights on "

  • Provides transmission expansion services to members

  • Works with members on solving commercial issues that impact system reliability

Western Transmission Congestion & Initiatives

  • Rocky Mountain Area Transmission Study (RMATS).

    • Formed by Gov. Freudenthal (Wyo.) & Gov. Leavitt (UT).

    • Initiated in August 2003.

    • Electric Power Industry Reluctant to invest in Transmission.

    • Evaluate All Potential Transmission Alternatives in the Rocky Mountain Region.

    • Results showed several Wyoming transmission plan upgrade opportunities.

Western Transmission Congestion & Initiatives

  • TOT3

    • SE Wyoming to NE Colorado route.

    • MOU between WAPA/WIA/Trans-Elect to study and develop the project.

    • 500 MW line/345kV/$318 million.

    • Solicitation for statement of interest issued November 2005.

  • TransWest

    • Wyoming to Arizona route.

    • Cost range of $2-5 billion.

    • Two 5000 kV transmission lines.

    • Currently in feasibility study phase.

    • Plans predict the lines will be in service by 2013.

    • May provide utilities in AZ, NV, NM, CA, CO and UT access to additional resources to meet load growth.

Western Transmission Congestion & Initiatives

  • Frontier Line

    • Announced by Governors of CA, NV, UT and WY in April 2005.

    • Wyoming to California route.

    • $3.5-5.0 billion in transmission assets/$10-15 billion in general assets.

    • Facilities development of renewables (wind) and mine mouth coal plants.

    • Phase 1 Feasibility Study initiated.

  • Northern Lights Project

    • Wyoming/Montana to Southwest U.S. Route

    • Cost Range $1+ Billion

    • Part of two leg plan to move power out of Alberta, Canada

    • 3.000 MW capacity, DC line

    • Plans predict on-line date of 2011
