Voters in Maine and New York showed up at the polls on election day to support ballot measures that would conserve vast woodlands, clean air and clean water.

In Maine, voters approved a measure to halt construction of the New England Clean Energy Connect (NECEC) transmission line under development by Central Maine Power (CMP) by a 60% to 40% vote, as of Wednesday. The line would funnel 1,200 MW of hydropower from Canada through Maine to Massachusetts.

Construction of the line has already begun, but “the time has come for CMP to respect the will of Maine people by stopping this project immediately,” Pete Didisheim, advocacy director at Natural Resources Council of Maine, said in a statement.

If the company refuses, the Department of Environmental Protection “should move quickly to suspend the permit and require that CMP begin restoring areas of Western Maine that have already been damaged,” Didisheim said.

“We also call on Massachusetts to honor this electoral outcome by selecting an alternative option for meeting its climate goals without imposing significant environmental harm on another New England state,” he said.

CMP parent company Avangrid (NYSE: AGR) filed a lawsuit Wednesday in the Maine Superior Court challenging the constitutionality of the referendum to limit the construction of high-voltage transmission lines in the forests of Western Maine.

“While the outcome of this election is disappointing, it is not the end of the road, and we will continue to advocate for this historic and important clean energy project,” the company said in a statement.

Avangrid asked the Superior Court for an immediate injunction preventing retroactive enforcement of the initiative against the project, “so that ongoing time-sensitive and essential construction is not disrupted while this lawsuit proceeds before the courts,” the company said.

Avangrid expects the court to rule on the injunction request promptly.

Right to Clean Air, Water

In New York, just over 60% of voters approved a measure to create a constitutional right to clean air and water in the state’s bill of rights.

“In these otherwise polarizing times, a healthy environment, breathing clear air and drinking clean water are values that bring people together,” Peter Iwanowicz, executive director of Environmental Advocates New York, said in a statement.

The measure will allow environmental justice communities experiencing pollution to fight for their rights in court, potentially accelerating the clean energy transition, according to the organization.
