PORTSMOUTH, N.H. — New Hampshire’s largest utility says its biomass project in Portsmouth has received more than 151,000 deliveries of wood chips from local foresters to support 150 to 200 jobs as it gets ready to enter its 10th year of operation.

When Eversource’s Northern Wood Power unit was completed and became operational in December 2006, it permanently replaced a 50-megawatt coal-burning boiler with a system that uses clean wood chips for fuel.

It generates enough electricity to power approximately 50,000 New Hampshire homes and reduces air emissions.

The project has generated more than 2.8 billion kilowatt hours of renewable energy produced and delivered to Eversource customers and the regional energy market. It’s consumed more than 4.6 million tons of clean wood chips, displacing coal, and added more than $380 million to the regional economy.

Eversource says the majority of the wood consumed by Northern Wood Power comes from local forests within 50 miles of Portsmouth: 61 percent come from New Hampshire, 29 percent from Massachusetts and 10 percent from Maine.
