ISO New England Inc. (ISO-NE) is an independent, non-profit Regional Transmission Organization (RTO), headquartered in Holyoke, Massachusetts, serving Connecticut, Maine, Massachusetts, New Hampshire, Rhode Island, and Vermont. [1]

ISO-NE oversees the operation of New England's bulk electric power system and transmission lines, generated and transmitted by its member utilities, as well as Hydro-Québec, NB Power, the New York Power Authority and utilities in New York state, when the need arises. ISO-NE is responsible for reliably operating New England's 32,000 megawatts [MW] (43,000,000 hp) bulk electric power generation and transmission system. One of its major duties is to provide tariffs for the prices, terms, and conditions of the energy supply in New England. [2]

ISO New England's stated mission is to protect the health of New England's economy and the well-being of its people by ensuring the constant availability of electricity, today and for future generations. ISO New England ensures the day-to-day reliable operation of New England's bulk power generation and transmission system, oversees the administration of the region's wholesale electricity markets, and manages comprehensive, regional planning processes.

Its board of directors and over 500 employees have no financial interest to any company doing business in the region's wholesale electricity marketplace.

ISO-NE was created in 1997 by the Federal Energy Regulatory Commission, as a replacement for the New England Power Pool (NEPOOL), which was created in 1971.

The ISO-NE grid does not extend to remote parts of eastern Maine in Washington and Aroostook Counties. In these areas, residents receive their electricity from Canadian providers such as NB Power and Hydro-Québec. [3]


New England's electric power industry, like that of the entire nation, changed dramatically during the past few decades. Until the 1970s, the industry consisted of utilities that handled every aspect of providing electricity: generating it, transmitting it and then distributing it to homes and businesses. These utilities were regulated local monopolies that operated independently of each other.

The Northeast Blackout of 1965 marked a turning point for the region's electric power industry. It shut down power for 30 million customers. On January 1966, the Northeast Power Coordinating Council (NPCC) formed to improve system reliability. Concerned about the system's reliability, the Northeast's power companies formed three "power pools" to ensure a dependable supply of electricity. The New England Power Pool (NEPOOL), formed in 1971 by the region's private and municipal utilities, was intended to foster cooperation and coordination among utilities in the six-state region.

During the next three decades, NEPOOL created a regional power grid that now includes more than 300 separate generating plants and more than 8,000 miles of transmission lines—all interconnected and dedicated to ensuring that New England never again has a region-wide power failure.

While the electric power industry's regulated monopolies worked well for generations, by the 1990s the lack of competition provided little reason to improve service, minimize prices or invest in new facilities and technologies. In New England, electricity rates were among the nation's highest, and the region had an antiquated electric power infrastructure.

In the early 1990s, Congress and the Federal Energy Regulatory Commission (FERC)—which oversees the electricity industry nationally—began enabling the restructuring of wholesale electric power. They believed competition would provide needed renewal, much as it had in transportation, telecommunications and financial services.

The FERC created a level playing field for competitive markets, ensuring equal access to transmission grids and encouraging states to require utilities to sell off power plants and gradually eliminate regulator-set rates in favor of prices determined by the markets.

In 1996, FERC Order 888 deregulated portions of the electric power market.

In 1997, the RTO created a management system for the regional bulk power system and new wholesale markets and ensure access to transmission systems.[ citation needed]

In 1999, the RTO began managing restructured regional wholesale power markets.[ citation needed]

In 2001, the RTO proposed a Standard Market Design, and rules to govern new wholesale markets.[ citation needed]

In 2003, the ISO New England Board of Directors voted to pursue the creation of an RTO for New England.[ citation needed]

In 2003, the RTO implemented the Standard Market Design, an improved wholesale market design for the region.[ citation needed]

In 2004, the FERC conditionally approves ISO New England as an RTO.[ citation needed]

In 2005, ISO New England begins operation as a Regional Transmission Organization.[ citation needed]

In 2008, the RTO held the first auction under the new Forward Capacity Market, designed to ensure the region continuously develops the resources needed to meet demand and maintain reliability.[ citation needed]

In 2010, culminating four years of development and staged implementation, the RTO launched the final phase of the Forward Capacity Market.[ citation needed]

Creating independent system operators

The FERC created independent system operators, or ISOs, to oversee restructuring on a regional basis. These ISOs were given responsibility for ensuring reliability and establishing and overseeing competitive wholesale electricity markets.[ citation needed]

ISO New England was created by FERC in 1997. Five of the six states have required utilities to sell off their power plants, and 88 percent of the region's generation is unregulated, the most in the nation.[ citation needed]

The move to markets

Working closely with the New England Power Pool, now a group of generators, utilities, marketers, public power companies and end users, ISO New England implemented wholesale markets in 1999. About 400 market participants complete $10 billion in wholesale electricity transactions annually.[ citation needed]

ISO New England has enhanced these markets in 2003, when it adopted a “Standard Market Design (SMD).” SMD added features such as a Day-Ahead Market to protect against price volatility and locational pricing that improves efficiency by accurately gauging the true cost of producing and supplying power anywhere in the region.[ citation needed]

Markets demonstrate real returns

The markets quickly demonstrated real benefits by encouraging investment in New England's power supplies. Between 1999 and 2003, New England experienced a 34%, or about a 10,000 megawatts [MW] (13,000,000 hp), increase in new power plants, significantly improving reliability and making genuine competition possible. Since the beginning of wholesale markets in New England in 1999, generator availability has increased from 81% to 89%. Suppliers have responded to economic incentives to keep their plants running when demand is highest and scheduling planned maintenance during off-peak periods, allowing for greater efficiency and the reduction in consumer cost of electricity. Before the establishment of markets, customers paid the full cost of power plants regardless of their overall performance levels or system needs.[ citation needed]

Volatility in the price of natural gas and oil, which together fuel more than 60% of the region's generating units, has kept overall wholesale electricity prices high—a trend that likely will continue until the region reduces its reliance on these fuels to produce electricity. Factoring out the cost of fuel that plants use to generate electricity, wholesale electricity prices continue to remain stable.[ citation needed]

Since the new power plants typically use more efficient and cleaner-burning natural gas technology, they also produce fewer pollutants. This has reduced emissions of nitrogen oxides (NOx), sulfur dioxides (Sox) and carbon dioxide (CO2, a substance that contributes to global climate change).[ citation needed]

The lights stayed on in almost all of New England during the August 2003 system failures that blacked out much of the Northeast, Midwest and Canada.[ citation needed]

The RTO is working to eliminate artificial barriers that add to the cost of importing or exporting power from other areas, and it is developing additional market mechanisms that promote investment of needed resources in the right locations.[ citation needed]

Strengthened oversight and governance through RTOs

In 2005, FERC designated ISO New England as the regional transmission organization for the six-state region. In this role, ISO New England continues to fulfill its responsibilities, but with broader authority over the day-to-day operation of the transmission system and greater independence to manage the power grid and wholesale markets.

There are 6.5 million customer households and businesses.[ citation needed]
