Managing Manure for Sustainable Heat and Electricity Production(ST7288-1)

Sheland Farms


Sheland Farms is a dairy with 700 mature cows, located in northern New York State. The farm milks three times per day, six hours per milking, and is planning an expansion that will increase its electric load and demand. The cold climate of the northern part of the State presents operational challenges for anaerobic digesters, which must be kept warm. Handling frozen manure is particularly problematic.

Project Description

An anaerobic digester gas-fueled CHP system incorporating a 100 kW internal combustion engine-generator set will be constructed and operated at the farm. The recovered heat will be used to heat the digester, pre-heat the frozen manure, and dry digested solids for bedding material.


The project will result in cost savings of over $55,000 per year to the farm, from a reduction in the purchase of energy and bedding materials. The project will also reduce odor due to land application, which is a significant benefit to the neighborhood.

Project Results

The digester and combined heat and power system are operating as designed.
