Nodal Reliability Performance Measures WorkshopProject No. 37052 Public Utility Commission of Texas June 12, 2009
Nodal Reliability and Regulatory Oversight • Goals for Go-live: • Adequate PUCT oversight of market on first day • Enforcement to consider new market limitations • Reasonableness • Metric adjustment and tuning process • Reliability and Compliance Training Plan • Monitoring reports are tested and useable • Longer term plan for additional metrics, if needed • Clear communication of regulatory oversight and risk
Approach • PUCT, Texas RE, IMM and ERCOT ISO have taken a proactive approach • Define a minimum set of reliability metrics and criteria (NPRRs and NOGRRs) necessary to enable go live • Implement a gap analysis • Create NPRRs and NOGRRs to fill gaps • Work through Stakeholder process to enact in time for market trials with urgent status • Ensure proper reports are ready for monitoring and enforcement • Create regulatory training and roll out plan
Other Issues • Plan to submit resulting NPRRs and NOGRRs to ERCOT process for approval using urgent status • Leverage NOGRR-025 work and integrate results into stakeholder process • Reliability metrics and criteria to be in place for market trials for testing • Minimized impact to Nodal Project (no code changes to core systems)
Reliability Issues • 55 issues affecting reliability of the ERCOT grid were identified • Of these, 24 are deemed to be critical for Nodal go-live regulatory oversight • Of these 24, 12 will require protocol or operating guide changes • The remaining 12 issues are already addressed in existing protocols or operating guides • Many of the other 31 issues will be ready for go-live or should be addressed within a short time frame after nodal go-live
Design Requirements • Criteria must be defined that detail what he expect behavior is and how it will be measured • Metrics must be defined that clearly identify what is passing and what is failing • The mechanism for monitoring performance, reporting potential failure and communicating this to Texas RE must be included
Reporting • Reports will need to be developed to generate exception reports on a periodic basis (e.g. monthly) to identify failures of calculated metrics • Complaint process may be used to identify incident-oriented failures • Trending metrics may be defined that are intended to monitor an issue but that are not intended to be used for violations
