Every day, the people of PSNH work hard to power New Hampshires homes, businesses, and community organizations. And at the same time, New Hampshire helps power them. Watch our latest TV commercials and see how at PSNH, the power is in our people.
PSNH is installing "scrubber" technology at Merrimack Station, which will significantly reduce sulfur dioxide and mercury emissions.
Using wet flue gas desulfurization technology—a scrubber system—the project is expected to capture at least 80 percent of the mercury in the coal and reduce sulfur dioxide emissions by more than 90 percent. By law the project must be operating no later than July 2013. The Clean Air Project will supplement more than $50 million in previous investments at Merrimack Station to reduce particulate emissions and nitrogen oxides.
