Construction Of Eversource's New Seacoast Power Line Is Almost Done


The fight against Eversource’s new Seacoast transmission line is winding down, with construction nearly complete.

Environmental advocates withdrew their state Supreme Court appeal against Eversource’s Seacoast Reliability Project in mid-December.

The court challenge had been unsuccessful in blocking the most controversial part of the project – a process known as “jet plowing,” which buried the transmission line under Little Bay.

Remaining power line construction – including overhead and underground wires – will finish up in Durham, Newington and Portsmouth during January and February.

Eversource says the transmission line, when complete, will help prevent power outages and meet new electricity demand in the area.

A dispute over how regulators considered the project's impacts to private property owners is ongoing at the state Supreme Court.
