Construction has begun on renewable natural gas facilities at three Indiana landfills, which will capture methane and convert it into pipeline quality natural gas. Electric cooperative Wabash Valley Power Alliance and Indianapolis-based Kinetrex Energy are partnering on the $146 million project.

The sites are located at the Twin Bridges Landfill in Danville, the Prairie View Landfill in Wyatt and the Liberty Landfill in Monticello.

Kinetrex, which is a subsidiary of Kinder Morgan Inc. (NYSE: KMI), says the facilities are expected to produce a total of 3.5 billion cubic feet of RNG each year. They hope to launch gas production in the fall of 2022.

 “As a result of this project, Kinetrex becomes a cooperative member and Wabash Valley Power Alliance’s involvement affords the production of alternative energy resources that will benefit our environment,” said WVPA Executive Vice President of Engineering and Operations Brian Fitzgerald.

Waste Management, which owns the landfills, will operate the new RNG facilities. WVPA will continue to have generation facilities at the sites that will remain in operation. WVPA says it first began energy production from landfill gas in 2002 and will continue to operate at six additional sites.
