What are peak shaving and demand response?


There are cleaner, cheaper alternatives to these power plants that don’t pollute our air or cost nearly as much. The first alternative is happening already: demand response, or peak shaving.

Demand Response

During times of peak demand, customers, especially those that use a lot of electricity, can save a substantial amount of money by reducing their electricity demand for a few hours. ISO-NE determines the quantity of capacity to charge each business or municipal building based solely on the demand in that building during the one annual peak hour on the grid. Given the right forethought, this provides businesses and municipalities the opportunity to save big by “peak shaving”, “load-shedding,” or reducing consumption, during the expected annual peak hour – sometimes as much as 30% of their bill.

MAPC’s Peak Demand Notification Program: Each morning from June to mid-September, MAPC sends out an email that assesses the risk that the annual peak could occur that day and, if so, at what time. The notifications also include an outlook for the next week so businesses & municipalities have time to plan ahead. MAPC develops this assessment by analyzing data provided by the grid operator, ISO-NE.

Another form of demand response is peak shaving. This can be done by anyone, businesses, municipalities or individuals. One of the easiest ways is to sign up for a peak notification, so you’ll know when peak demand is going to occur and can cut back your energy use during those crucial hours.
