PJM said it was a quiet operations month in November with zero spinning events, nine post-contingency local load relief warnings (PCLLRWs) and one reserve sharing event with the Northeast Power Coordinating Council (NPCC).
The load forecast error came in at 2.22% — well below the 3% margin and a far cry from the unsolved load deviation witnessed during the first two days of October. (See “DR Load Forecast Error Unsolved” in PJM OC Briefs: Nov. 12, 2019.)
Fall Restoration Drills
PJM said its fall restoration drills conducted between Sept. 25 and Oct. 30 went well, with only minor complaints about the simulator and event duration.
Some 143 companies and 52 PJM operators participated. All of the RTO’s nuclear plants received off-site power under the four-hour deadline with one exception, due to simulator issues.
Companies said the drill should last two days and requested more practice on cross-zonal procedures. The simulator itself took some getting used to, Brian Lynn told the Operating Committee on Tuesday.
The spring drills are scheduled for May 19 and May 20.
Manuals Endorsed
The committee endorsed:
- Manual 38: Operations Planning — Periodic review to conform NERC standard references, remove the PJM-NYISO seasonal operating study and update Attachments A and B.
- Manual 14-D: Generator Operational Requirements — Remove references to PJM’s Tariff regarding the definition of “generating facility.” The term is not defined in the Tariff, pending a ruling on FERC Order 845 compliance.
