Load representatives concerned by reports of generators’ bidding strategies in May’s PJM capacity auction reacted by threatening to block an initiative by Exelon Corp. to provide more informative supply curves.

PJM members endorsed the removal of a requirement that interchange transactions last at least 45 minutes to comply with a FERC mandate.

The Market Monitor said members should reject proposals to change the way capacity supply curves are represented, saying they would expose confidential data.

Stakeholders approved a rule change to the PJM zonal base load definition so that zones don’t lose Auction Revenue Rights due to anomalies caused by storms or other extraordinary events.

Stakeholders approved two initiatives to improve demand response measurement and verification.

PJM members approved rule changes to reduce “adder” payments to frequently mitigated generation units (FMUs), after rejecting a joint proposal from the RTO and the Market Monitor.

Acknowledging they were taking “a leap of faith,” stakeholders last week endorsed PJM’s plan for cutting uplift and capturing reserve costs in energy prices.

The PJM Intermittent Resources Task Force will consider ways to implement recommendations of the recently completed PJM Renewable Integration Study.

Stakeholders split last week over a PJM proposal to change how the RTO captures the cost of deploying additional reserves during extreme weather.

Stakeholders will attempt to develop more accurate measurement and verification of residential DR under a problem statement approved by the MIC.
