The Merrimack Station, New Hampshire's final coal-fired power plant, has shut down operations three years earlier than scheduled, marking a pivotal moment in the region's energy landscape. This closure enables Granite Shore Power to pursue plans for transforming the site into a clean energy complex featuring solar panels and battery storage systems. The decision comes amid a broader trend of declining coal viability in New England, where natural gas and renewable energy sources have increasingly dominated the market. In recent years, Merrimack operated only sporadically, generating a mere 0.22 percent of the region's electricity in 2024. The plant's closure is emblematic of the ongoing transition in energy generation, as coal facilities struggle to compete economically. Advocates express optimism about the future of the site, despite uncertainties surrounding federal renewable energy policies.
