The Operating Committee last week unanimously agreed to create a task force to close the gap between PJM metering requirements and member practices.
The Metering and Metering Requirements Task Force will be tasked with revising Manual 1: Control Center and Data Exchange Requirements.
“Manual 1 is deserving of a rewrite; it’s been too long,” PJM’s Ryan Nice said. “Metering is important because it’s a large capital investment, and it feeds into a lot of settlement applications.”
The changes will aim to address “long-standing clarity and readability issues” that have caused gaps between PJM’s “intended meaning and member understanding” on metering requirements, according to the problem statement.
Among the topics to be considered are meter maintenance and calibration standards. The group will examine existing metering infrastructure and common practices, particularly among transmission owners.
The work is expected to take three to six sessions.
Members should send names of those interested in joining the task force to ryan.nice@pjm.com.
Proposal Would Curtail RegD Resources in Regulation Market
The Regulation Performance Impacts group has proposed a modified benefits factor curve and a situational cap on “RegD” megawatts to address the issue of PJM’s regulation market purchasing too much of the fast-responding resources at times.
“We believe currently the benefit curve factor is not defined correctly,” PJM’s Eric Hsia said. “There is a need to change. This is a starting point.” (See PJM Market Monitor: Faulty Marginal Benefit Factor Harming Regulation.)
The solution, which will be brought up for a vote at the group’s Sept. 25 meeting, involves moving the benefits factor curve to the left so that it is at 0 at 40%. A cap of 26.2% also would be implemented during identified excursion hours — hours when dispatch frequently manually moves the regulation signal.
In addition, the group proposes a “tie-breaker logic” for the benefits factor ranking to address the issue of the adjusted total cost formation being ineffective when RegD self-schedules or is offered at $0.
“We want to review this quarterly,” Hsia said. “Nothing’s etched in stone.”
