There have been efforts to organize to close the Merrimack station at multiple points over the years, and strong local efforts to install pollution controls. However, there hasn’t been much grassroots movement of late.
However, in 2017 a group of people of faith, led by Quakers from across New England, walked between the Schiller station in Portsmouth and Bow. Their pilgrimage ended in a 24-hour encampment blockading the tracks that supply the plant with coal.
Their action put the station back in the spotlight again as the last remaining large coal plant in New England without a shutdown date, and gained significant press coverage. You can find more press coverage of the action and pilgrimage on their website: https://climatepilgrimage.org/news/
