State Intelligence

Updated May 26, 2026

Utility Landscape

Eversource Energy (Public Service of New Hampshire)

IOU

Southern and central New Hampshire, largest electric utility in the state serving approximately 560,000 customers

Subject to ongoing scrutiny over distribution rate design and storm cost recovery. NHPUC has historically challenged Eversource on ROE levels and capital expenditure prudency, particularly following major storm events.

Liberty Utilities (formerly Granite State Electric)

IOU

Northwestern New Hampshire, serving approximately 42,000 electric customers in the Lakes Region and North Country

Algonquin Power & Utilities subsidiary operating under Liberty brand; has pursued incremental rate adjustments tied to grid reliability investments and AMI deployment in a largely rural, low-density service area.

National Grid (Unitil subsidiary: Unitil Energy Systems)

IOU

Seacoast and southern New Hampshire communities including Hampton, Exeter, and surrounding towns

Unitil has pursued modest but regular distribution rate cases; commission has focused on grid modernization cost allocation and whether AMI infrastructure costs are prudently incurred.

Liberty Utilities (Granite State Water)

IOU

Water service in select southern New Hampshire communities including Derry and surrounding municipalities

Has faced rate case proceedings tied to infrastructure replacement surcharges (WSRS) and PFAS remediation cost recovery, which remains a contentious issue before the NHPUC.

New Hampshire Electric Cooperative (NHEC)

coop

Rural central and northern New Hampshire, approximately 84,000 meters across 115 towns — largest electric cooperative in New England

NHEC operates with significant autonomy as a member-owned cooperative but remains subject to NHPUC jurisdiction on certain matters; has been active in community solar and distributed energy resource programs.

Concord Municipal Electric Department

muni

City of Concord, serving approximately 15,000 electric customers within municipal boundaries

As a municipal utility, subject to limited NHPUC oversight; has navigated power supply procurement and renewable portfolio standard (RPS) compliance obligations under state law.

Key Issues

  • Eversource NH electric distribution rate case: A pending or anticipated general rate case involves contested issues around return on equity, capital investment prudency for grid hardening, and the appropriate treatment of vegetation management costs following repeated storm-related outage events in 2024–2025.

  • PFAS contamination cost recovery in water rates: Liberty Utilities (Granite State Water) and other water providers are seeking recovery of substantial PFAS remediation and treatment capital costs through rate base inclusion and surcharge mechanisms, raising questions about cost causation and ratepayer versus shareholder responsibility.

  • Default energy service and competitive electricity market restructuring: NHPUC is engaged in ongoing proceedings examining the structure of default service rates, the role of competitive suppliers, and whether current market rules adequately protect low-income and residential customers from price volatility.

  • Renewable Portfolio Standard (RPS) compliance and Class I/Class II resource sufficiency: New Hampshire's RPS obligations are tightening, and the commission is addressing shortfalls in qualifying renewable energy certificates (RECs), compliance carve-outs for biomass and thermal resources, and the financial impact of Alternative Compliance Payments on ratepayers.

  • Grid modernization and AMI deployment cost allocation: Multiple IOUs have pending or recently approved AMI and advanced grid technology investments; the NHPUC is scrutinizing benefit-cost methodologies and whether deployment timelines and vendor contracts reflect prudent utility management.
