Chicago-based Amp Americas II LLC has acquired a dairy renewable natural gas operation from Fair Oaks Farms. The company, which developed the project for California-based Generate Capital, says the acquisition, along with one other outside Indiana, has tripled the size of its carbon-negative fuels portfolio.

Amp Americas says it has operated and managed the dairy RNG assets for Generate Capital since 2019.

The Fair Oaks operation includes five digesters and two gas processing plants that capture methane from about 1.5 million gallons of dairy waste generated by 36,000 cows across nine dairies per day.

Amp Americas says the process purifies and compresses the methane into carbon-negative renewable natural gas that can be used as transportation fuel, instead of the methane being released into the atmosphere.

The company acquired a similar operation in Idaho from Vitol Green Holdings LLC.

“We have an agile structure and proven ability to finance, build, own, operate, market, and deliver renewable energy projects—all under one roof,” Grant Zimmerman, chief executive officer of Amp Americas, said in a news release. “We believe the strength of these acquisitions, combined with our existing asset portfolio, will enable us to continue to make meaningful contributions to the decarbonization of the transportation and agriculture sectors.”

The Fair Oaks facility began operation in 2012. Amp Americas operates another, larger dairy RNG facility in Jasper County as well, which opened in 2018.

Amp Americas says it now operates seven of the largest dairy biogas-to-transportation fuel projects in the country.

Financial terms of the acquisitions were not disclosed. However, a spokesperson for the company tells Inside INdiana Business there was no negative impact to jobs as a result of the deals.
