Twinsburg Wastewater Treatment Plant Combined Heat and Power Addition
Several years ago, the wastewater treatment plant in Twinsburg, Ohio, was regularly flaring methane gas from the plant’s 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 combined heat and power (CHP) system.
GEM Energy’s Capstone C65 microturbine, was the equipment of choice. The resulting CHP system uses the excess methane to generate 65kW in electricity for the plant’s 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 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’s startup and worked collaboratively with us on resolving the issue to obtain optimum performance of our unit and its gas conditioning system.John Adams, Wastewater Supervisor
