Installation design for alternative energy facility

About this project

client
Avant Energy, Inc.
location
Minnesota
cost
$250,000
completion date
2015

An alternative-energy facility in Minnesota generates 8 MW of power from food-processing wastes and livestock manure. Biogas generated by anaerobic digestion is used as fuel in four on-site 2,000 kW engine gensets that supply electric power to the local community. The digestate is sold to local farmers for land application as fertilizer.

Initially, Barr assisted our client by providing support for an environmental review and permits for air, wastewater, stormwater, and water supply. Subsequently, we were hired to provide facility engineering design and support for procurement and bidding and construction. Facility features included a large receiving hall, materials-handling systems, shredders, anaerobic digesters, biogas storage tanks, gas blowers, gas flares, sludge-drying equipment, and the gas-fired engine generators.

The project received national recognition as “Biogas Project of the Year” by the American Biogas Council. It was also featured in POWER Magazine. You can read the full article online here.
