Maine’s ethics watchdog has resolved alleged campaign finance law violations surrounding the controversial New England Clean Energy Connect project.

The two entities targeted in a probe by the Maine Commission on Governmental Ethics and Election Practices consented to a combined $210,000 in penalties in an agreement executed Nov. 29. Neither admitted liability or wrongdoing, but both agreed they should have registered as a political action committee or ballot question committee.

The NECEC line is designed to carry up to 1.2 GW of electricity from hydro facilities in Quebec to Massachusetts. It has faced multiple challenges since it was first proposed in 2017, including a citizen referendum seeking to block construction. Avangrid resumed construction in August 2023, four months after winning a key court ruling. (See New England Clean Energy Connect Wins Court Battle.)

Two separate but related cases arising from the fight over NECEC went before the Maine ethics commission, one involving Clean Energy for ME LLC (doing business as Stop the Corridor), the other involving Alpine Initiatives LLC.

Advocates for NECEC complained in January 2020 that Stop the Corridor should have registered as a political action committee because it engaged in financial activities to support petitioning for a citizen initiative on the project.

Stop the Corridor challenged the ethics probe, dragging out the time frame.

The commission ultimately gathered 6,339 pages of documents and conducted five interviews to show the involvement of Stop the Corridor in efforts to block NECEC or impede progress on it.

The commission concluded Stop the Corridor qualified as a ballot action committee, should have registered with the commission and should have filed campaign finance reports.

Among its other findings, the commission discovered Stop the Corridor made payments to Alpine Initiatives. A consultant transferred $160,000 to Alpine, which then donated $150,000 to the Maine Democratic Party, the leaders of which were viewed as more likely to oppose NECEC.

The public did not learn of the source of this pass-through contribution because it was reported only in Alpine’s name.

The commission began to investigate Alpine in July 2021, concluded Alpine through its actions did qualify as a political action committee and said it should have registered as such and filed a campaign finance report.

Alpine agreed to pay $160,000 in civil penalties, and Stop the Corridor agreed to pay $50,000.

Supporting documentation posted in the Spot the Corridor case shows only one source of money: $95,726 provided by NextEra Energy Resources from August 2019 to March 2020.

NextEra operates the 1.24 GW nuclear power station in Seabrook, N.H., and through the years, the Florida-based utility has run interference on the NECEC project, which would provide an influx of low-cost clean energy competing with the emissions-free output of Seabrook.

A late 2021 report indicated NextEra spent $20 million to influence public opinion against NECEC in the runup to the Maine referendum.
