NEPOOL Generation Information System The NEPOOL Generation Information System is an operational database and information exchange platform used within the New England Power Pool framework to collect, validate, and disseminate generator and resource data for ISO New England market operations and planning. It supports coordination among electric utilities, independent system operators, regional transmission operators, and market participants by consolidating resource attributes, availability, and capability information to inform capacity markets, energy markets, and reliability assessments.
The system aggregates generator nameplate, fuel, emissions, and operational capability data supplied by asset owners including Exelon Corporation, NextEra Energy, Calpine Corporation, National Grid, and Eversource Energy to serve stakeholders such as ISO New England, the Federal Energy Regulatory Commission, and regional planners like the New England States Committee on Electricity. It interoperates with datasets used by entities such as NEPOOL Participants Committee, Market Monitoring Unit (MMU), North American Electric Reliability Corporation, and regional transmission organizations, enabling analytics for forward capacity auction participants, demand response providers, and distributed energy resource aggregators.
Originally developed in the 1990s during restructuring discussions involving the Federal Energy Regulatory Commission's orders on deregulation and wholesale electricity reform, the platform evolved alongside the formation of ISO New England and the consolidation of the New England Power Pool. Early iterations addressed generator reporting requirements emerging from events like the Northeast blackout of 1965 and policy shifts influenced by legislative actions such as state-level renewable portfolio standard adoptions in Massachusetts, Connecticut, Vermont, New Hampshire, Maine, and Rhode Island. Over successive upgrades, integration points expanded to include interfaces for market systems used by firms like GE Energy Consulting, PJM Interconnection, and compliance tools referenced by the Environmental Protection Agency.
The database maintains detailed records including unit capabilities, outage schedules, fuel type and contracts, emissions data, heat rates, and operational constraints used by system operators to perform unit commitment, dispatch, and contingency analysis. It supports processes for capacity market qualification, resource adequacy modeling, ancillary services scheduling, and reporting for state regulators such as the Massachusetts Department of Public Utilities and Connecticut Department of Energy and Environmental Protection. Data elements are used by modeling suites from vendors like Siemens and ABB as well as academic studies at institutions such as Massachusetts Institute of Technology, Harvard University, and Northeastern University.
Governance is collaborative, involving the NEPOOL Participants Committee, asset owners including Dominion Energy, AES Corporation, and municipal utilities, regulators including Federal Energy Regulatory Commission commissioners, and operational oversight by ISO New England staff. Stakeholders also include market monitors, investor-owned utilities, municipal aggregators, and environmental advocates such as Conservation Law Foundation and renewable developers like Iberdrola and Avangrid. Policy inputs come from state energy offices, regional planning bodies like the New England States Committee on Electricity, and federal agencies including the Department of Energy.
The architecture uses relational and transactional components to support batch and real-time exchanges with supervisory control and data acquisition systems, energy management systems from vendors like SCHNEIDER ELECTRIC and Honeywell, and market systems managing locational marginal pricing. Integration leverages standard data schemas and message exchanges compatible with Common Information Model, EIX interfaces, and custom APIs employed by participants such as ISO New England and third-party vendors. Cybersecurity and interoperability considerations reference frameworks by North American Electric Reliability Corporation and Cybersecurity and Infrastructure Security Agency.
Data from the system informs compliance with Federal Energy Regulatory Commission Orders, state renewable portfolio standards, emissions tracking for Environmental Protection Agency reporting, and reliability standards enforced by North American Electric Reliability Corporation and regional entities. It supports audit trails for forward capacity market qualification, transparency requirements advocated by consumer groups, and filings before state regulatory commissions including the New Hampshire Public Utilities Commission and Maine Public Utilities Commission.
By centralizing validated generator information, the system reduces transaction friction for participants in forward capacity auctions, improves accuracy in unit commitment and economic dispatch decisions, and contributes to long-term transmission planning conducted by ISO New England and regional planning authorities. It underpins analyses on fuel-security influenced by pipeline projects like the Algonquin Incremental Market, transmission proposals such as Northern Pass, and the integration of renewables led by developers like Ørsted and Vestas. The system thereby affects investment decisions by utilities, merchant generators, and policymakers shaping electric sector transformation across New England.
