CARMEL, Ind. — MISO will next year discontinue submitting data to NERC’s Generating Availability Data System (GADS) on behalf of generation in its footprint.
Executive Director of Resource Planning Patrick Brown announced the move Wednesday during a Resource Adequacy Subcommittee meeting. The RTO will send its last report Feb. 15, 2020, NERC’s deadline for 2019 GADS data. Generators will be on their own for first-quarter 2020 reporting, due May 15. GADS is mandatory for conventional generating units at or above 20 MW, and for wind farms of 75 MW or higher that were commissioned in 2005 or later.
MISO currently submits GADS data for about 56 generators, but staff have previously said the RTO wants to remove itself from the process.
“When we started submitting them, it was a smaller group. … It doesn’t seem like we’re adding much value by doing them, from our perspective,” Director of Resource Adequacy Coordination Laura Rauch said at a July Market Subcommittee meeting.
Independent Market Monitor staffer Mike Chiasson recommended that MISO ensure it still has visibility into GADS reporting. He noted that RTO members have had issues with GADS accuracy in the past.
MISO is still planning to make a formal announcement on the change during the September RASC meeting. To assist its generators, the RTO has begun coordinating a training, scheduling and communication plan with NERC, SERC Reliability, Midwest Reliability Organization and Reliability First Corp.
