About Us > What We Do

Our Three
Critical Roles

Reliable Electricity, Competitive Prices

ISO New England is the independent, not-for-profit company authorized by the Federal Energy Regulatory Commission (FERC) to perform three critical, complex, interconnected roles for the region spanning Connecticut, Rhode Island, Massachusetts, Vermont, New Hampshire, and most of Maine. Together, these three responsibilities help protect the health of the region’s economy and the well-being of its people by ensuring the constant availability of competitively-priced wholesale electricity—today and for future generations.

The ISO’s unique mission requires active stakeholder involvement, as well as a highly skilled workforce across a wide range of disciplines. One goal lies at the heart of this mission: reliability.

Things We Don’t Do

x

Handle retail electricity—the power you buy from your local utility or electric company.

x

Own, maintain, or repair the power grid’s infrastructure, such as power plants, power lines, and substations.

x

Have a stake in companies that own the infrastructure. This keeps us independent and able to make objective decisions about the power grid for the good of all New Englanders.
