Microgrid design for water utilities: Fort Wayne’s approach with CDM Smith

Bob Crossen speaks with Laurel Schaich of CDM Smith about a microgrid initiative developed by Fort Wayne’s water utility in Indiana. The project connects the city’s drinking water plant, wastewater plant, and stormwater retention ponds under a single energy management system.

By integrating renewable energy sources — including floating solar panels, natural gas generators, and biogas-fueled combined heat and power — the utility aims to reduce electricity costs, improve resiliency, and maintain affordable rates for customers. Schaich outlines the planning, data analysis, and implementation challenges, and reflects on how this model could shape future energy strategies for utilities.
