The farm has a milking herd of about 2,950 cows. The farm has been operating an anaerobic digester system since 2012, capturing biogas from manure in order to power a 600 KW genset. The electricity produced was utilized by the farm with excess being sold to the local utility.  

MCR was contracted to refurbish the biogas system and install Renewable Natural Gas (RNG) upgrading equipment.  This high quality RNG may be used for heating or transportation purposes.

This farm is part of a three-farm system; the digesters capture, extract and clean the methane from dairy manure and convert it into RNG which is injected into a nearby gas pipeline for distribution. Collectively, three farms generate about 189,000 million British thermal units (MMBtu) of renewable natural gas each year.
