The MISO market was competitive in 2017, but the RTO should do more to address increasing congestion and low capacity prices, Monitor David Patton said.

MISO’s markets performed competitively but should implement several changes to improve market functions, the 2017 State of the Market report concluded.

MISO and PJM challenged the contention by MISO’s Independent Market Monitor that PJM’s two long-term market-to-market (M2M) errors have cost MISO millions.

MISO’s Monitor is backing the RTO’s proposal to allow generators to recoup a portion of make-whole payments even when their ramp rates fall short.

ISO-NE defended its proposed two-stage capacity auction, responding to criticism by its External Market Monitor and others.

Competitive transmission, hurricane forecasts and maximum generation alerts were among the topics at the GCPA MISO South regional conference.

The MISO Market Monitor is seeking to use the RTO’s recent refiling of its resource adequacy construct to force a FERC ruling on changing its capacity demand curve.

The MISO Board of Directors learned about the recent discovery that PJM had been committing two market-to-market (M2M) errors.

MISO and PJM expect to begin implementing a two-part remedy to their double-charging of congestion fees on pseudo-tied generation early next year.

Monitor David Patton said PJM has for years been committing two market-to-market operations errors that have possibly cost MISO millions of dollars.
