MISO Files Revised Resource Adequacy Proposal At FERC
September 05,2018
The Midcontinent Independent System Operator, Inc. ('MISO'), through an August 31 refiling, proposed at FERC to revise certain locational aspects of its resource adequacy construct of its Open Access Transmission, Energy, and Operating Reserve Markets Tariff ('Tariff').
MISO said that this proposal, originally created through an extensive stakeholder process over the past few years and filed with the Commission in March 2018, "aligns auction inputs and pricing for internal and External Resources while recognizing the unforeseeable risks capacity market changes may impose on pre-existing, long-term capacity arrangements."
MISO said that, "More specifically, these revisions are the same that MISO proposed in the March Locational Enhancement Filing other than two aspects the Commission found to be unjust and unreasonable. The revisions create External Resource Zones ('ERZs'), allocate excess auction revenues to Load Serving Entities impacted by changes to MISO’s resource adequacy construct through Historic Unit Considerations ('HUCs'), and align parameters used to calculate auction inputs such as Capacity Import Limits ('CIL'), Capacity Export Limits ('CEL'), and Local Clearing Requirements ('LCR') with the use of these limits in the Planning Resource Auction ('PRA')."
MISO requested an effective date for the filing of November 1, 2018 to allow for the inclusion of these provisions in the 2019/2020 Planning Year.
