A cogeneration plant at the State Correctional Institution at Laurel Highlands, in the US state of Pennsylvania, which generates electricity and steam from landfill methane gas, has come on line.
Working with Johnson Controls, the prison's cogeneration plant produces electricity and steam using gas from the nearby Mostoller landfill site, and thereby eliminating the need for the prison to use coal fired boilers.
"We look forward to protecting our state's environment through the operation of this state-of-the-art plant while, at the same time, reducing utility costs at our prison," corrections secretary John Wetzel said.
Any excess electricity produced by the plant is sold back to the power grid, creating ongoing revenues for the prison and helping to offset project costs.
