GHILTON, Wisconsin – The Storms Farm anaerobic digester installation, “Swine Farm Biogas Renewable Energy Project,” earned a National Recognition Award as part of the American Council of Engineering Companies (ACEC) 2015 Engineering Excellence Awards Gala Tuesday evening in Washington, DC.
The National Recognition Award is a prestigious distinction honoring projects that demonstrate exceptional achievement in engineering.
“We are honored to receive the ACEC National Recognition Award,” said Withers & Ravenel, Inc. Vice President, Sam Ravenel. “The completed project is a waste-to-energy facility that works, benefits the environment – and, most importantly, can be replicated.”
Project engineer, Withers & Ravenel, anaerobic digester designer, DVO, Inc., project developer, AgPower Partners, LLC, and Storms Farm collaborated on the project, constructing the largest swine biogas renewable facility in North Carolina.
DVO’s Two-Stage Mixed Plug Flow™ anaerobic digestion technology at Storms Farm allows the farm to be much less reliant on lagoons, provides benefits for both waste handling concerns and energy production, and greatly reduces odor and greenhouse gas emissions.
“The digester is great for the environment, the swine industry, the state and our farm. We couldn’t be more pleased with our system,” said Billy Storms, owner of Storms Farm.

About Storms Farm
Storms Farm, owned by Billy Storms, is North Carolina’s largest renewable energy facility using swine waste. The 600-acre farm has 23 barns, nearly 30,000 hogs and 444,000 chickens.
About The Storms Hog Power Anaerobic Digester Project
The Storms Hog Power anaerobic digester and renewable energy generating system, in tandem with an enhanced animal waste extraction and collection system that uses scrapers instead of flush water to remove manure from the houses, greatly reduces the negative environmental impacts of the current lagoon and spray field manure management systems, while profitably generating renewable energy and other valuable byproducts.
Manure collected daily from nearly 30,000 hogs, formerly treated in open air lagoons, mixed with off site agricultural wastes which were previously either land applied or destined for a landfill, is biologically decomposed in an oxygen-free, 1.2 million gallon reinforced concrete vessel. The bacteria in the digester metabolically break down the organic waste streams and generate energy-rich biogas, while destroying nearly all of the pathogens and odor. The biogas is combusted in an engine/generator, sending enough clean renewable electricity to the local utility to offset the electricity consumption of nearly 300 average size homes in the area.
North Carolina Electric Membership Corporation purchases all of the electricity under a long-term contract. This revenue, combined with tipping fees for processing the off-site agricultural waste, the sale of the carbon credits and Renewable Energy Certificates, and the sale of other valuable byproducts, support the sustained operation and maintenance of the facility.
The anaerobic digester was designed by DVO. The site layout, building and feedstock delivery systems were designed by Withers & Ravenel. AgPower Partners oversaw the entire project, procuring all construction, financing, power off-take, utility interconnection and renewable energy attribute contracts.
