Market Participant Readiness

Overall registration and qualification status for Market Participants is RED

• Situation

• A number of Market Participants are not in compliance with MP11 (Registration Activities)

• There are an estimated 215 RARFs representing 720 unit-specific resources, 671 of which are modeled (the remaining 49 are distributed generation resources).

• 91% (608 of 671) of Generation and Load Resource units have been submitted, representing 93% of MW capacity

• Most RARFs are expected to be returned to MPs for revision (most likely several rounds)

• Current rate of acceptance [with Tier 1 review] of submittals into RARF database is about 80%

Acceptance does not indicate valid data

• QSE’s w/Resources that represent Resource Entities who are missing RARFs will be rejected from EDS trials

• June 16 closed loop LFC test (and preceding open-loop test) will not be conducted until 100% of MW capacity has been accepted by ERCOT

• Mitigation Steps

• Contacted non-responding resource entities [completed]

• Developed a temporary work-around for TML submission [completed]

• Ongoing outreach to MPs to assist in addressing issues [ongoing]

• Publish “wall of shame” for non-responsive entities [ongoing]
