New England Power Pool (NEPOOL) The New England Power Pool (NEPOOL) is a regional power coordination arrangement created to coordinate electric generation, transmission planning, and market operations across Connecticut, Maine, Massachusetts, New Hampshire, Rhode Island, and Vermont. Established in the early 1970s amid changing energy landscapes including the 1973 oil crisis and the growth of regional transmission projects such as the New England Transmission Corporation, NEPOOL evolved through interactions with federal institutions like the Federal Energy Regulatory Commission and regional entities including the Independent System Operator New England and the New England Governors and Eastern Canadian Premiers (NEG-ECP). NEPOOL's legacy includes technical standards, market rules, and collaborative planning that influenced later constructs such as the Regional Transmission Organization model and the development of the Regional Greenhouse Gas Initiative.

History

NEPOOL originated in 1971 as a response to reliability and coordination challenges faced by utilities such as Boston Edison Company, Public Service Company of New Hampshire, and Central Vermont Public Service. Early years were shaped by the Northeast blackout of 1965 lessons and federal policy shifts under administrations like Richard Nixon and later Jimmy Carter energy initiatives. Throughout the 1980s and 1990s NEPOOL engaged with restructuring milestones including the Energy Policy Act of 1992 and tariff reforms spearheaded by the Federal Energy Regulatory Commission under chairs such as Elizabeth Moler. NEPOOL's procedures were instrumental during wholesale market redesigns that led to the formation of ISO New England in 1997 and subsequent market refinements following events including the Northeast blackout of 2003 and the 2000–2001 California electricity crisis ripples in regional policy. Over decades NEPOOL membership and governance adapted as merchant generators like Calpine Corporation and Dynegy entered markets and as public power entities such as the New Hampshire Electric Cooperative and Vermont Electric Cooperative sought representation.

Structure and Membership

NEPOOL's membership historically encompassed investor-owned utilities (e.g., National Grid plc, Eversource Energy), municipal systems (e.g., Burlington Electric Department), generation owners (e.g., NSTAR, Dominion Energy affiliates), marketers, and consumer advocates such as Acadia Center. Governance was organized through committees mirroring practices at organizations like the North American Electric Reliability Corporation and the Electric Reliability Council of Texas for technical standards. Voting sectors often included groups resembling the structure used by PJ MISO and regional forums such as the New England States Committee on Electricity. NEPOOL's stakeholder processes paralleled those at U.S. Department of Energy-affiliated regional programs and reflected precedents set by the Midwest Independent System Operator. Membership seats and voting rules evolved in tandem with market reforms championed by companies like Exelon and regulators such as Jon Wellinghoff.

Market Operations and Governance

NEPOOL developed operating procedures, tariff schedules, and market rules that influenced the design of wholesale markets operated by ISO New England. Core market constructs included day-ahead and real-time energy scheduling concepts used by California Independent System Operator and New York Independent System Operator. NEPOOL committees addressed issues such as capacity market design, congestion management, and ancillary services, themes also debated in forums like the Federal Energy Regulatory Commission dockets and the North American Electric Reliability Corporation standards-setting. The pool's deliberations interacted with market reforms from entities like FERC Commissioner Jon Wellinghoff and market participants including PJM Interconnection and Entergy Corporation. NEPOOL processes were critical during implementation of locational marginal pricing methods pioneered by New York ISO and in adapting market power mitigation measures used by Federal Energy Regulatory Commission orders.

Transmission Planning and Reliability

NEPOOL coordinated regional transmission studies, reliability criteria, and interconnection procedures comparable to practices at the North American Electric Reliability Corporation and in planning bodies like the New England States Committee on Electricity. Large transmission projects considered by NEPOOL stakeholders included multi-state upgrades akin to the Maine-New Hampshire tie-line and regional initiatives similar to the Seabrook Station interface reinforcement. NEPOOL supported planning exercises that integrated resource adequacy models and contingency analyses used by entities such as NERC and the Eastern Interconnection operators. Interaction with investor-owned utilities like National Grid plc and municipal utilities ensured that outage scheduling, system protection studies, and reactive power support followed criteria referenced in standards like those of the Institute of Electrical and Electronics Engineers and industry groups such as the Electric Power Research Institute.

Regulatory and Legal Framework

NEPOOL operated within a regulatory regime shaped by statutes and administrative bodies including the Federal Energy Regulatory Commission and state utility commissions in Massachusetts Department of Public Utilities, Connecticut Public Utilities Regulatory Authority, Maine Public Utilities Commission, New Hampshire Public Utilities Commission, Rhode Island Public Utilities Commission, and Vermont Public Utility Commission. Legal interactions involved precedent-setting litigation and settlement processes similar to cases before federal courts and appeals such as those in the United States Court of Appeals for the District of Columbia Circuit and influenced by legislation like the Public Utility Regulatory Policies Act of 1978. NEPOOL's rule changes were reviewed through FERC filings and state regulatory proceedings, often engaging stakeholders including non-profit advocates like Conservation Law Foundation and industry trade associations such as the Electric Power Supply Association.

Key Projects and Initiatives

NEPOOL played a role in initiatives addressing reliability, market design, and integration of resources including demand response programs similar to those implemented by ISO New England and capacity market reforms reflecting debates seen in PJM Interconnection. Projects involved integration of variable resources comparable to Iberdrola Renewables and NextEra Energy wind deployments, regional transmission upgrades analogous to those promoted by National Grid plc, and coordination on reliability investments paralleling discussions in the Regional Greenhouse Gas Initiative. Collaborative research and pilot programs drew participation from academia and labs such as Massachusetts Institute of Technology, Northeastern University, and the National Renewable Energy Laboratory. NEPOOL's legacy persists in ongoing stakeholder platforms and in institutional arrangements that influenced successors across the eastern Interconnection.
