PJM will revise its eMKT application to capture more detailed information and require generation owners to use it to verify their operating parameters under a proposal outlined to members last week.

Generation owners will be required to ensure all data in eMKT is accurate, particularly notification times, minimum run times, unit status and unit limits (emergency and economic min & max).

PJM will also require owners to make all updates in eMKT, and operators will use only that data for unit commitment decisions. Verbal notifications will be permitted only if previous unit commitments cannot be met or a unit trips or encounters other problems in real time.

“We want to get away from all the phone calls and changing information in real time,” said PJM’s Chantal Hendrzak, who presented the proposal to the Markets and Reliability Committee Thursday. “We want to be able to pull that information out of eMKT.”

Among the additional information that PJM will be requiring are details on units’ dual-fuel capabilities (e.g., time to transition, megawatt output during transition) and operational restrictions (e.g., emissions limits).

Generators would also be able to update their energy offers and cost-based start-up and no-load costs during the operating day to reflect gas-price volatility.

The proposed changes are expected to be brought to an Operating Committee vote next month.
