Ottawa Generating Station
Energy production from Ottawa Generating Station is enough to power approximately 3,800 homes.
Ottawa Generating Station produces electricity from landfill gas 24 hours a day, 365 days a year. The project’s partners, Granger and Republic Services, and electric customer, Consumers Energy, work together to bring renewable energy to Michigan communities.

Granger is the developer and built and operates the electric generating station. Republic Services, Inc. is an industry leader in U.S. non-hazardous solid waste and recycling. Ottawa County Farms Landfill, owned by Republic, supplies the landfill gas. Consumers Energy is a public utility that provides natural gas and electricity to more than 6 million of Michigan’s 10 million residents. It serves customers in all 68 of the state’s Lower Peninsula counties. Consumers Energy purchases electricity produced at the generating station.
Ottawa County Farms Landfill opened in 1982 and as of 2014 had 6,200,000 tons of waste in place. The 191-acre facility is expected to be in operation for approximately 11 more years; energy production is projected to continue for an additional 20 to 30 years after it is closed.
Ottawa Generating Station has been online since 1994. The project uses landfill gas from Ottawa County Farms Landfill to fuel multiple on-site engine generator sets. These powerful pieces of equipment consist of 1,100 or 2,200 horsepower engines similar to the engine of a car, only much larger. The engine drives the attached generator, which produces electricity. Ottawa uses six engine generator sets with the capacity to produce a total of 6.4 megawatts of electricity.
A small amount of the energy produced at Ottawa Generating Station is used directly to supply the generation facility itself, with the majority of electricity being delivered to the utility’s grid to supply local homes and businesses.
