ISO New England is a regional transmission organization (RTO), serving Connecticut, Maine, Massachusetts, New Hampshire, Rhode Island and Vermont. ISO New England meets the electricity demands of the region by operating the New England bulk electric power system, providing centrally dispatched direction for the generation and flow of electricity across the region's interstate high-voltage transmission lines, administration of New England's wholesale electricity marketplace, and management of comprehensive market planning processes that address New England's electricity needs well into the future.

Economic Programs

The NEISO's Real Time Price Response program allows energy users to take advantage of periods of high market prices. The ISO will notify participants when prices are forecasted to be more than $.10/kwh either the night before or during the event day. Customers are paid an energy payment for the hours they participate, and their participation is strictly voluntary. In the Day-Ahead option, customers bid their load into the Day-Ahead Market, and are notified if their bid has cleared by 4:00 pm the day before the day they are committing for. They are then obligated to reduce load during the cleared hours to match their bid commitment. Metering requirements for these programs are hourly, submitted either daily or monthly.

Reliability Programs

The Real Time Demand program is designed for customers that can make a commitment to reducing load during a regional reliability problem. The customer can select whether they can reduce load within either 30 minutes or 2 hours of the ISO request, which determines the amount of the energy payment a customer will receive during a called event. A higher payment goes to customers that can respond quicker. The customer is paid a capacity payment based on the ICAP Market Price (or a transition payment) for their commitment as well. This program requires 5 minute interval meter data transmitted by Internet Based Communication System (IBCS). For more information, click here.
