FAQs

  • Q: Why do you ask customers to avoid using power?

    The appeal is made to reduce customer demand, to balance generating capacity and demand in New England and to help maintain uninterrupted power for customers.

    Heavy electricity use, hot weather and limited available generating capacity can prompt ISO New England, in conjunction with New England's utilities, to issue this appeal.
