PLWG Report to RPG

September 24, 2013

Presented by John Moore, PLWG Chair

August PLWG Meeting will be held tomorrow, September 24

Key PGRR’s to be addressed:

PGRR031 “Implement 95% Facility Rating Limit in Planning Criteria”

PGRR028 “Evaluation of Compliance of Reactive Requirements”

Active PGRRs Under Consideration• PGRR028 “Evaluation of Compliance of Reactive Requirements”

– ERCOT will present updated PGRR language• PGRR030 “New Planning Guide Section 8A, Declaration of Resource Data

Accuracy”– ROS directed PLWG to address stakeholder concern re: extent of timeframe

requiring filing of updates for resources being planned for interconnection.– A small group has met to offer revised language for consideration.

• PGRR031 “Implement 95% Facility Rating Limit in Planning Criteria”– Two alternatives have been developed for consideration.– The alternatives address different approaches to justify new projects based on

95% loading; one addresses the concern to establish language that does not incorporate the justification within the Planning Criteria and eliminate a potential conflict with NERC compliance requirements.

• PGRR032/NPRR567 “Stakeholder Review of Resource Registration Data Requirements”– Review RDWG’s proposed language addressing processes for changing

resource registration data requirements

Wrap-up of OPSTF Issues List

• If time permits, additional consideration will be directed to consider two remaining issues that have not been completely addressed with current and recently approved PGRRs:– Issue 5c – How to consider discrete load additions– Issue 10 - Security-constrained deliverability of ancillary
