The Meadow Rock Project

In Greenville, Michigan, the Meadow Rock Renewable Natural Gas (RNG) project will convert 75,000 gallons of manure per day into renewable natural gas each year. The RNG produced at Meadow Rock will be injected into the ANR Pipeline. Developed in partnership with Chevron, the project is expected to begin producing in the first half of 2022.
We’re proud to be partnering with Brightmark on anaerobic digestion projects at two of our Michigan dairy farms. The Brightmark team has been responsive to our needs from day one, and we’re looking forward to the sustainability and financial benefits of the project.
