Summary

This presentation discusses how DCWater reduced operating costs and energy costs by constructing a 15MW waste-to-energy CHP at their Blue Plains advanced waste water treatment facility located in Washington, DC. They successfully reduced biosolid volume by 50%, generated 30% of daily power demand, reduced electricity cost by $10M, and lowered greenhouse gas emissions by ~40%. The project required 100% use of digester gas across multiple consumers from a variable source, which required the programming of advanced and innovative controls.
