Cogeneration, also referred to as Combined Heat and Power (CHP), has been around for quite some time. In the past 5 to 10 years, the technology for CHP systems has improved significantly and the technology to treat Biogas has also improved dramatically giving us the ability to achieve significantly more uptime/output, while managing maintenance costs to those consistent with burning natural gas.
With the ability to achieve better results more reliably, cogeneration is a significant opportunity for wastewater treatment biogas producers to benefit in the following ways:
- Positive Impact on Economics in Multiple Areas
- Produces power at a cost below retail electricity
- Displaces purchased fuels for thermal needs
- Better digestion increases CHP output and reduces tipping fees
- Qualifies as a renewable fuel for green power programs
- Enhances power reliability for the treatment plant
- Opportunity to reduce greenhouse gas and air emissions
