Cogeneration System Upgrade

The Miami-Dade Water and Sewer Department (WASD) completed a fast-track capacity upgrade that replaced WASD’s existing cogeneration system with state-of-the-art equipment that generates almost triple the electrical capacity without discharging additional air pollutants. This is one of the first cogeneration systems of this size (8 megawatts) that is capable of using three different types of fuel feedstocks (digester, landfill, and natural gas) in an infinitely variable mix. The Brown and Caldwell/Poole & Kent design-build team completed the project on schedule and within budget, providing nearly $1 million in electrical cost savings to WASD.
