  82. Slide 82: Overview

    OVERVIEW » Reliability first! Implementing a west- wide resource adequacy program must be a priority for the region as the regions resource mix changes » Currently 26 utilities are participating in the WRAP non-binding program phase » Western Power Pool is the Program Administrator and filed a tarif

  83. Slide 83: Today's Objectives

    TODAY'S OBJECTIVES » Provide an overview of the loads and resources in the WRAP MW footprint » Provide and overview of installations and nameplate for wind and solar » Provide an overview of the QCC and ELCC values for each resource class » Provide an overview of Planning Reserve Margin values (PRM)

  84. Slide 84: Before We Begin

    BEFORE WE BEGIN » Modeling provided utilizes WRAP program design, assuming full binding implementation of the WRAP as designed − Metrics assume diversity benefit and a level of forward procurement on aggregate that is not presently expected without implementation of the WRAP » Modeling was performed
