- Designed and implemented a Combined Heat and Power (CHP) system to capture and repurpose biogas generated from the wastewater treatment plant’s digester, transitioning from flaring to high-efficiency energy recovery.
- Installed a 100 kW CHP system utilizing a reciprocating engine to generate electricity from methane derived from biogas, supported by a biogas treatment system featuring dehumidification and activated carbon filtration to prevent equipment corrosion and ensure consistent fuel quality.
- Integrated a fuel blending system capable of combining treated biogas with pipeline natural gas to enhance operational flexibility and reliability. Recovered waste heat from electric generation is redirected through a circulating water loop and connected to the plant’s existing water heating system, improving thermal efficiency.
- Achieving an overall energy efficiency of more than 80%, the CHP system significantly outperforms the previous boiler-only heating setup, maximizing renewable energy use while reducing emissions.
- With a project investment of $2 million, the initiative is projected to create 45 full-time equivalent jobs, generate over $106,000 in local and state tax revenue, and stimulate more than $6.6 million in economic activity.
