BMW Spartanburg Landfill Gas Project
Spartanburg, SC. -- The new Methane gas system is nearing completion and will include two new highly-efficient gas turbine generators capable of producing 11 Megawatts of electricity. These two new co-generation turbines will replace four older, less-efficient gas turbines. The new turbines have the capability to increase electrical output from the current systems 14% up to almost 30% of the plant’s current total electrical demand. While the new turbines double the overall electrical output using the same amount of methane gas, the combined cycle electrical and hot water generation supply over 60% of the plant’s total energy needs.
“BMW’s landfill gas program has been a tremendous initiative for the plant,” says Josef Kerscher, President of BMW Manufacturing. “Using methane gas to power our plant is one example of our focus on environmentally-friendly production processes.”
In addition to adding larger turbines and heat recovery boilers, BMW will integrate a new specialized treatment system to remove siloxanes from the methane gas (a compound common to landfill gas and potentially destructive to gas turbines). Two of the four original 1,200kW gas turbine engines will remain in place to serve as a back-up for the new system.
BMW’s original landfill gas project was implemented in December of 2002 with the methane gas produced from a nearby Waste Management operated landfill in Wellford, SC. The initial infrastructure allowed for collecting, cleaning, and compressing methane gas, transporting it through a 9.5-mile pipeline to the BMW plant, compressing and then using it to power four gas turbine generators.
To date the landfill gas project has saved BMW an annual average of $5 million in energy costs. With the addition of the new turbines, this project will return an additional average annual cost savings to BMW of up to $2 million and reduce carbon dioxide emissions by approximately 92,000 tons per year.
BMW's landfill project is the only project that co-generates electricity and hot water for use at an industrial location remote from the landfill. Additionally, based on calculations provided by the EPA, the reduction of 92,000 tons per year of carbon dioxide emissions is equivalent to the benefit of planting over 23,000 acres of trees annually or 30 times the size of New York’s Central Park.
