The Power Generation Facility at the Joint Water Pollution Control Plant was originally constructed in the mid 1980s to generate power from gas produced through anaerobic digestion of biosolids removed from wastewater. The combined cycle process utilizes gas turbine generators for combustion of the digester gas.  Additional power is produced by recovering waste heat from the turbine exhaust, generating steam and driving a steam turbine generator. The existing facility produces up to 22 megawatts (MW) of power, enough to provide for all of the power needs of the treatment plant. The Steam Cycle Modifications project is the last in a series of plant modifications designed to increase maximum plant capacity to 36 MW, more than enough to power the treatment plant well into the future. The $25 million project includes replacement of the existing heat exchangers which generate steam from the hot gas turbine exhaust, replacement of the existing steam turbine with a higher capacity unit and replacement/upgrade of auxiliary facilities to support the upgraded system. The new design draws upon more than 15 years experience with the existing facility and will result in greater overall efficiency and reliability.
