The Planning Committee at its June 7 meeting endorsed assumptions to be used in the 2018 Reserve Requirement Study that are similar to those of the previous year, with two exceptions.
Regarding generator performance, the new method for developing a winter peak week capacity model will better account for the risk of a large volume of concurrent outages that are historically observed during this period.
Secondly, a wind or solar generator with three or more years of operating data will be modeled based on its actual performance. The capacity value of units with less than three years of operating data will be modeled as a blend of actual performance and class-average capacity factor.
The study results will re-set the installed reserve margin (IRM) and forecast pool requirement (FPR) for delivery years 2019/20, 2020/21 and 2021/22. They also will establish initial IRM and FPR for 2022/23.
Also endorsed, over one objection, were revisions to Manual 20: PJM Resource Adequacy Analysis. These changes will allow the new method of developing the winter peak week’s capacity model to be used in the Reserve Requirement Study.
In addition, the committee discussed the load model to be used in the study.
Patricio Rocha-Garrido, senior engineer – Resource Adequacy Planning, recommended using a 10-year load model, 2003-2012, for the study’s base case. He also suggested switching the “world” peak to a different week in July so that PJM and the world will peak in the same month, but not in the same week.
It is the same load model used for the past two years. The committee will be asked to endorse the selection at its July meeting.
The interest garnered by proposed modifications to Attachment C of Manual 14B: PJM Region Transmission Planning Process was so strong that, before the Planning Committee meeting had even adjourned, a special session was announced to discuss the subject via WebEx/teleconference from 9 a.m. to noon on June 20.
The changes are aimed at making deliverability procedures more transparent and easier to follow for stakeholders as well as correcting any conflicts between how the procedures are described and how PJM actually implements them.
In other business, the committee heard a first reading of a proposed split of Manual 14A into a revised Manual 14A: New Services Requests Study Process and a new Manual 14G: Generation Interconnection Requests.
