Situation
Bocci developed a green power solution for the Almeda Sims Wastewater Treatment Plant, integrating a 1.5 MW natural gas turbine with heat recovery into the facility’s newly replaced rotating drum sludge dryers. Through extensive performance modeling, the team engineered a CHP system that supplies approximately 75% of the plant’s electrical load and 70% of its thermal demand without exporting excess power. The system met the city’s energy, environmental, and financial performance requirements.
Projected Results:
• 76% combined system efficiency
• ~7 tons/year reduction in NOx
• ~5.5 tons/year reduction in SOx
• 5,000+ tons/year reduction in CO₂
