Potential to Set Peak Energy Demand

Over the next few days there is a good chance that we may set the peak energy demand for the year due to the expectation of high temperatures.  If possible, we are recommending that customers with interval meters reduce their electricity use, especially during the hours of 3 p.m. to 6 p.m. on Wednesday and Thursday in NYISO,  ISO-NE, and PJM. Peak usage is set during the highest demand hour of the year in NY and NE, and the average of the five highest days in PJM. This determines the Cap Tag/Peak Load Contribution (PLC) assigned to you for the following capacity term. By planning to curtail your electricity usage on these days, you will help to reduce your capacity charge and overall electricity costs for the following year.
