New England’s Clean Power CorridorsCoverage from Valley News, New Hampshire Bulletin, and others

New England is expanding transmission links intended to move Quebec hydropower and northern Maine wind into the regional grid.
The operating New England Clean Energy Connect line has delivered power but produced uneven early results, while Maine’s proposed wind-and-transmission package remains subject to permitting, financing, environmental review, and federal approval. These projects could increase nonfossil electricity and generate consumer and local economic benefits, but performance depends on export availability, construction timelines, and coordination across states and grid operators.

The story now extends beyond NECEC’s uneven operations to a concrete northern Maine wind-and-transmission buildout. Maine has selected an 800-megawatt wind project and roughly 1,200 megawatts of transmission, though approvals, financing, and environmental reviews remain unresolved.

The main update is a sharper assessment that NECEC’s early operation has not yet clearly added net new clean power to New England, because marginal flows, outages, and falling use of the older Phase 2 route complicate the claim. The story also now emphasizes contractual protections and the broader constraint that Quebec hydropower availability may limit the line’s real contribution.
NECEC began cross-border electricity delivery from Quebec to New England in January, but early operations show uneven hydropower flows attributed to Quebec drought conditions.
Hydro-Québec faces reduced hydropower availability as NECEC exports into New England lag expectations after January operations during a Quebec drought.
NECEC, a Quebec-to-New England transmission line, began operations in January and has delivered limited net hydropower gains over six months amid Quebec drought and outages.
Project developers for the New England Clean Energy Connect transmission line agreed during Maine negotiations to help defray low-income residents heat pump costs as the hydropower link enters service in New England.
Maine regulators approved Clearway Energy’s 800-megawatt Aroostook County wind farm and Avangrid’s 111-mile transmission line, subject to federal and environmental reviews.
Maine regulators selected Clearway Energy and Avangrid Networks in 2025 to develop an 800 MW wind farm and 1,200 MW transmission line connecting northern Maine with New England.
The Maine Public Utilities Commission approved a paired wind and transmission project in northern Maine to connect Aroostook County resources with New England's grid.
Governor Janet Mills announced on 2026-01-16 that NECEC began operation, delivering 1,200 MW from Quebec to New England and $15 million for Maine heat pumps.
On January 16, 2026, the 145 mile Quebec to Maine transmission line began delivering hydroelectric power to New England, with heat pump funding included in Maine's benefits package.
Maine Public Utilities Commission closed bidding for a December 2025 RFP seeking northern Maine wind and solar plus 1200 MW of new transmission for the New England grid.
Governor Kathy Hochul announced completion of the Champlain Hudson Power Express HVDC transmission line in 2022-2024, delivering Canadian clean power to Queens and projecting 37 million metric tons of emissions reductions through 2040.
Hydro-Quebec and New England clean energy stakeholders report limited NECEC electricity gains after January operations as Quebec drought reduces hydropower and line idle periods occur in late May and early June.
CHPE and SunZia transmission projects began or are nearing full operation in 2024, moving Quebec hydropower and New Mexico wind to US cities to support decarbonization goals.
After NECEC started in January, early operations show marginal renewable-energy gains for New England as Quebec drought reduces hydropower exports over cross-border lines.
Maine expands heat pump and heat pump water heater deployment to reduce heating-oil use, energy bills, and improve clean-energy job growth between 2023 and 2027.
Governor Janet Mills announced $43 million for Maine heat pump water heater rebates in 2020s, supporting instant discounts via Efficiency Maine and a New England Accelerator through 2029.
