What is ISO-NE?


Created in 1997 and regulated by the Federal Energy Regulatory Commission, ISO New England (ISO-NE) is the area’s independent power system operator. ISO-NE oversees the bulk electric power system, including power plants and the transmission system throughout New England, and helps set the prices, terms, and conditions of our region’s energy supply.

ISO-NE has three essential roles: 1) coordinating and directing the flow of electricity over the region’s transmission system, 2) designing and overseeing the wholesale market for electricity, and 3) planning for the region’s energy future. The third role is especially relevant for the Greater Boston and New Hampshire Solution; in this case, ISO-NE has conducted assessments and identified specific reliability issues in New Hampshire and Greater Boston area that must be addressed promptly.
