ISO New England is the regional transmission organization that administers the wholesale electricity markets and manages the power system for six Northeastern United States states. It operates a high-voltage grid, runs competitive markets for energy, capacity, and ancillary services, and plans transmission expansion across Connecticut, Maine, Massachusetts, New Hampshire, Rhode Island, and Vermont. The corporation interacts with federal agencies, state utility commissions, investor-owned utilities, municipal systems, rural cooperatives, generators, and large end-users.
ISO New England's mission centers on ensuring reliable electricity supply, promoting competitive wholesale markets, and planning regional transmission. It coordinates operations among transmission owners such as Eversource Energy, National Grid, Avangrid, Unitil, Green Mountain Power, and Central Maine Power while complying with rules set by the Federal Energy Regulatory Commission and standards from the North American Electric Reliability Corporation. The entity interacts with market participants including Exelon Corporation, NextEra Energy, Calpine Corporation, Dominion Energy, and Dynegy and engages with state regulatory bodies such as the Massachusetts Department of Public Utilities, Connecticut Public Utilities Regulatory Authority, Vermont Public Utility Commission, New Hampshire Public Utilities Commission, Rhode Island Public Utilities Commission, and Maine Public Utilities Commission.
The organization emerged from industry restructuring in the 1990s influenced by the Energy Policy Act of 1992 and the Federal Energy Regulatory Commission orders that promoted open access and independent system operators. It was formed after decisions affecting utilities like Boston Edison and entities such as the New England Electric System and Central Maine Power Company. Early development involved coordination with regional bodies including the New England Governors and Eastern Canadian Premiers (NEG-ECP) and utilities participating in initiatives with ISO New England predecessors and counterpart organizations like PJM Interconnection, California Independent System Operator, and the New York Independent System Operator. Over time, structural changes involved interactions with market reforms, technology shifts driven by companies such as Siemens Energy, General Electric, and ABB Ltd., and regulatory proceedings before the United States Court of Appeals for the District of Columbia Circuit.
ISO New England operates day-ahead and real-time energy markets, capacity auctions, and ancillary service markets. It administers forward capacity auctions involving generation and demand-response resources from providers like Consolidated Edison, New England Power Pool Participants Committee, EnerNOC, ENGIE, and AES Corporation. Market design elements have been influenced by studies and filings involving entities such as The Brattle Group, Potomac Economics, and Analysis Group. System operations coordinate with control centers, transmission owners, and generators using protocols aligned with North American Electric Reliability Corporation standards and integrate resources including wind farms by Ørsted (company), solar installations by SunRun, and battery projects by companies like Tesla, Inc. and Fluence Energy. Cross-border ties involve interconnections with Hydro-Québec, New Brunswick Power, and transmission links such as High-voltage direct current transmission projects.
Planning activities produce regional system plans, including transmission needs assessments, interconnection studies, and resource adequacy forecasts. ISO New England’s studies address winter-peaking and summer-peaking scenarios, winter fuel-security concerns highlighted by events like the Polar Vortex and the Blizzard of 1978, and integration of renewables under state clean energy policies including Massachusetts Global Warming Solutions Act, Regional Greenhouse Gas Initiative, Connecticut's Comprehensive Energy Strategy, and New Hampshire's Renewable Portfolio Standard. Planning interfaces with transmission project sponsors like National Grid and Eversource Energy and coordinates with regional entities such as the New England Governors' Conference and independent consultants from Black & Veatch and Mott MacDonald. Reliability metrics and contingency analyses reference models used by the North American Electric Reliability Corporation and are subject to audits by the Federal Energy Regulatory Commission.
ISO New England is governed by a board of directors and engages a wide stakeholder community through committees and forums including the New England Power Pool (NEPOOL), consumer advocate groups such as Office of the Consumer Advocate (Vermont), Connecticut Office of Consumer Counsel, and industry coalitions like the Advanced Energy Economy. Stakeholders include independent power producers, utilities, transmission owners, demand-response providers, and large customers represented by organizations such as the Industrial Energy Consumers Group. Governance interacts with federal entities like the United States Department of Energy and state-level governors and legislatures across the six states. Market rules and tariff changes are debated within NEPOOL Participants Committee meetings and filed with the Federal Energy Regulatory Commission.
ISO New England has faced criticism over market design, capacity market outcomes, and handling of fuel-security risks. Debates have involved incumbent generators such as Calpine Corporation and Dynegy and new entrants including renewables developers represented by Free Press and Greenpeace USA advocacy in regional policy discussions. High-profile controversies include disputes about cost allocation for transmission projects like Grid New England proposals, capacity auction price signals criticized by state officials in Massachusetts and Rhode Island, and tensions over resource adequacy during cold snaps referenced by policymakers such as Martha Coakley and commentators in outlets like The Boston Globe and The Providence Journal. Legal and regulatory challenges have been litigated at the Federal Energy Regulatory Commission and in federal courts, with intervention from parties including NRG Energy, Entergy, and consumer advocacy organizations.
