PORTSMOUTH — Redhook Brewery is moving forward with a plan to install a co-generation system to produce its own electricity at the company’s Portsmouth brewery.

Tietjen Hynes, an engineer with Redhook Brewery, said the system could be up and running and producing electricity at its plant on the Pease International Tradeport as soon as October. “We’re hoping to offset about 10 percent of our energy use during the year, which is exciting,” she said Wednesday. The company has been working on the system for at least three years as part of its efforts to continue to be as sustainable as possible, Hynes said. “It’s a priority for our business,” Hynes said about Redhook’s sustainability efforts, which include having a corporate sustainability manager. The company’s plan is to use the methane gas generated by its wastewater plant on site to create electricity, Hynes said.

The plant has always treated its own waste before shipping it to the city of Portsmouth’s wastewater plant at the tradeport, Hynes said.
In the past, the methane gas they created by treating the brewery’s plant was simply “flared off,” Hynes said, but once the co-generation system is up and running, they’ll be able to use the methane to produce 500 megawatts per year of power.

The Pease Development Authority’s Board of Directors recently approved Redhook’s plans for a co-generation system.
Maria Stowell, engineering manager for the PDA, said Redhook has always treated its own waste, because brewery waste is typically high in biological oxygen demand (BOD) and suspended solids.

“It’s very common for breweries, they call it strong waste,” Stowell said.
