Biogas Projects

Oak Lea Farm

In 2011 The Climate Trust contracted with Revolution Energy Solutions for Smart Energy's fourth project. Oak Lea Farm, operated by Tim and Betty Bielenberg, has been in the family for multiple generations. It is the second in Oregon (Lochmead was the first in the state and the nation) to use a digester system that operates at much lower temperatures than conventional systems, making it much more energy efficient.

In addition to using cow manure, the digester accepts food waste to produce enough biogas to operate a 190 kW generator. This reduces waste sent to the local landfill.


"The Oak Lea anaerobic digestion project is meaningful and important on a number of levels," said Alan Tank, CEO and Managing Partner of Revolution Energy Solutions. "The project greatly enhances the sustainability of this family dairy farm, it reduces greenhouse gas emissions, it improves air and water quality and it produces enough renewable energy to meet the yearly needs of approximately 200 homes in Oregon."
