After this writing, we received additional information that the “5 CP” that PJM publishes and local distribution companies (LDCs) use for Peak Load Contribution must come from “non-holiday weekdays”. So, even if Saturday or Sunday end up among the five highest loads of the summer, they will not influence your capacity cost.
Electricity Use Reduction Recommendation
Friday, June 29, 2018 through Tuesday, July 3, 2018
From 3:00 p.m. to 6:00 p.m. on Friday through Sunday
From 2:00 p.m. to 6:00 p.m. on Monday and Tuesday
Tomorrow through Tuesday – Friday, June 29 through Tuesday, July 3 – daily maximum temperatures during this five-day period are expected to be in the '90's, possibly reaching 100. These high temperatures could impact your Capacity Peak Load Contribution (PLC) and future electricity costs. There is a high likelihood that an hour between 3 p.m. and 6 p.m. Friday through Sunday and/or 2 p.m. and 6 p.m. Monday and Tuesday will end up as one or more of the five highest peak loads of the year.
On June 1 of every year, each building is assigned a PLC number by your utility. Your PLC is based on your peak usage during the five hours of the prior year with the highest system demand. (Note: The selected hours come from five different 24-hour periods.) Peak usage generally occurs on the five hottest days of the year – and your usage this summer will affect the PLC for next summer.
We recommend that you reduce, whenever possible, your electricity usage from 3:00 p.m. to 6:00 p.m. tomorrow (Friday), Saturday & Sunday, and from 2 p.m. to 6 p.m. Monday & Tuesday. Your PLC can influence 10-30% of your electricity bill, so by lowering your PLC this summer you will be able to reduce your PLC and overall electricity costs for a full twelve-month period starting next summer (June 1, 2019 to May 31, 2020).
