2012 Smart Energy Biodigester Projects


In 2012 Smart Energy contracted two more projects: A family owned dairy in Tillamook, Oregon and an organic waste digester at an ENERGY STAR-rated potato processing plant in Moses Lake, Washington.

Misty Meadow

Misty Meadow is the fifth biodigester project for Farm Power, which recently celebrated its five-year anniversary.

A digester replaced a 16-million-gallon open tank at the family-owned farm in Tillamook, preventing more than 7,000 tons of greenhouse gas emissions from entering the atmosphere each year. Power generated from the digester is sold to Pacific Power.

Farm Power's mission is to keep the food supply near where people live. To do so, the company builds and operates digesters in partnerships with farms, which provide the manure. Brothers Kevin and Daryl Maas, who own Farm Power, do the project legwork, including designing the digesters and raising funds. So far, Smart Energy has participated in three projects with Farm Power.


Moses Lake

A unique feature of the ENERGY STAR-rated potato processing plant is a digester that treats wastewater and creates biogas. The gas is burned in boilers and used for plant operations.

This is the first Smart Energy Project that uses organic waste instead of cow manure as the feedstock for the digester. In all other regards the project is like a dairy digester; it captures methane for use as an on-demand renewable energy source.

Over the first five years, Smart Energy demand has grown to nearly 60,000 tons annually. This growing demand required the program to consider other high-quality offsets produced by methane-to-energy projects. Dairy digesters in the Pacific Northwest remain the preferred project type, but as demand grows we may consider other organic waste digestion projects. As with dairy projects, these organic waste digestion projects also provide benefits to communities, including diverting waste from landfills.
