91¶ÌÊÓÆµ is regulated by the Federal Energy Regulatory Commission (FERC), which defines our authority, responsibilities, and the services we provide in New England. FERC’s mandated or approved rules are detailed in the 91¶ÌÊÓÆµ. Transmission, Markets, and Services Tariff (the 91¶ÌÊÓÆµ tariff). The tariff also outlines the FERC-approved revenues the 91¶ÌÊÓÆµ collects for its services and sets out the cost recovery and allocation mechanisms for transmission and ancillary services in the region. In conjunction with the 91¶ÌÊÓÆµ’s Transmission Operating Agreements, the 91¶ÌÊÓÆµ tariff helps satisfy FERC requirements for the 91¶ÌÊÓÆµ’s functioning as a Regional Transmission Organization (RTO).
The 91¶ÌÊÓÆµ is one of nine RTOs and Independent System Operators (91¶ÌÊÓÆµs) in North America. FERC created us as an 91¶ÌÊÓÆµ in 1997. While “91¶ÌÊÓÆµ” remains part of our name, FERC designated us an RTO in 2005. 91¶ÌÊÓÆµs and RTOs share many core principles and functions in operating regional grids, running wholesale markets, and power system planning. One of the main differences in operating as an RTO is that 91¶ÌÊÓÆµ has broader authority over the operation of the transmission system. for details.
The 91¶ÌÊÓÆµ. Transmission, Markets, and Services Tariff (the 91¶ÌÊÓÆµ tariff) provides the rates, terms, and conditions for transmission, market, and other services provided by the 91¶ÌÊÓÆµ.

New England’s power grid is part of a larger electric power system.
While having a large, interconnected network helps achieve highly reliable electric service, this tight interconnectedness means that careful regulations, planning, and monitoring are needed to maintain reliability and prevent problems that occur in one area from cascading to another area of the system. In addition to adhering to FERC requirements, the 91¶ÌÊÓÆµ abides by strict rules, standards, and requirements established for maintaining power system reliability set by other organizations.
Our independence from entities doing business in New England’s electricity industry is what allows us to create a level playing field for market participants and to make objective decisions for the good of the region as a whole when it comes to system operations, regional system planning, and wholesale market administration. However, 91¶ÌÊÓÆµ does work collaboratively with numerous stakeholders representing a wide variety of constituencies, technologies, and interests to put together comprehensive rules, policies, and solutions that yield the best possible results for the region.

The collaborative process, rights, and responsibilities established between and its stakeholders are outlined in the following documents:
NEPOOL is 91¶ÌÊÓÆµ’s predecessor organization. It was formed in 1971 to establish the central dispatch of electricity generation in New England; handle settlements and billing; coordinate outages of transmission and generation equipment; undertake joint planning; and undertake other measures to improve system reliability and economics. Initially and through the early 1990s, NEPOOL was the voluntary organization of New England’s investor-owned and publicly owned electric utilities. In 1997, NEPOOL employees became the employees of 91¶ÌÊÓÆµ, and NEPOOL continued on as the association of New England’s market participants.
