Blocked in 2021. Carrying power in 2026.
Maine voters approved restrictions that halted the NECEC transmission project. A court case and jury verdict changed its path; EIA records commercial operation beginning January 16, 2026.
The short version
- The Maine court describes the November 2021 referendum as effectively halting the project.
- A later jury verdict favored the developer; the 1,200 MW line entered commercial operation in January 2026.
Why it matters. A successful vote against a project can be followed by a different legal and construction outcome. The dated trail shows what the opposition achieved—and what happened afterward.
The ballot was not the last chapter
In November 2021, Maine voters approved restrictions on high-impact transmission construction. The state’s court opinion, paragraphs 2 and 20, describes the result: the initiative effectively halted New England Clean Energy Connect.
The dispute then turned on whether construction already undertaken gave the developer protected rights to continue. The August 2022 ruling sent that factual question back for further proceedings. In April 2023, Avangrid reported that a jury had found in its favor.
The eventual result appears in an operating record: EIA dates commercial service to January 16, 2026. Follow the complete project trail.
A line is capacity—not a promise of constant imports
The new connection can transfer 1,200 MW. But EIA also documented interrupted imports during January’s severe cold, when Québec limited exports to meet its own demand.
Both facts matter. The line reached service after a documented halt, and the amount it carries still depends on operating conditions. Neither the original vote nor the capacity rating tells the whole story.
