On January 16, 2026, a $1.6 billion transmission line began delivering 1,200 megawatts of Canadian hydropower to the region—enough to meet 20% of Massachusetts' electricity needs and save ratepayers an estimated $50 million annually.

For 40 years, transmission bottlenecks and opposition blocked Hydro-Québec from selling more power to New England. On January 16, 2026, a 145-mile power line through Maine began delivering 1,200 megawatts of Canadian hydroelectricity to Massachusetts—20% of the state's needs and the largest clean energy transmission addition to the region in decades. The line went dark when a winter storm hit 10 days later.
