ISO New England (ISO-NE) (established 1999) operates the region's power grid and wholesale electric markets:
- Energy market: two-settlement (day ahead and real-time) spot market with locational marginal pricing (an internal hub, eight load zones and more than 500 nodes),
- Interim mechanism for acquiring installed capacity,
- Forward reserves market,
- Regulation market, and
- Financial transmission rights market.

-
Marginal fuel type: natural gas
Generating capacity (summer 2006): 30,895 MW
Very little new generation has been brought on line recently in New England. The ISO states that if this trend continues the region could begin to experience reliability issues as early as 2007-2008.
Capacity reserve (summer 2006): 2,768 MW (declining)
Reserve margin (summer 2006): 10% (declining)
