Several years ago, the wastewater treatment plant in Twinsburg, Ohio, was regularly flaring methane gas from the plant鈥檚 waste digester into the atmosphere. So, city leaders sought out a viable alternative to burning off this byproduct of the treatment process, and found a solution with a聽combined heat and power (CHP) system.

GEM Energy’s聽Capstone C65 microturbine, was the equipment of choice. 聽The resulting CHP system聽uses the excess methane to generate 65kW in electricity for the plant鈥檚 consumption. The cogeneration system also uses heat from the microturbine exhaust to heat the digester, increasing its efficiency.

Since implementing a CHP system, the city of Twinsburg’s WWTP聽has saved approximately $4,300 per month on its electricity and natural gas costs.

GEM Energy listened to the issues that we encountered on the unit鈥檚 startup and worked collaboratively with us on resolving the issue to obtain optimum performance of our unit and its gas conditioning system.
