Project Result
The project completed in March 2019 and the Final Report was published. The project successfully demonstrated a microgrid for a wastewater-treatment facility.
The Issue
Critical facilities are vulnerable to climate change impacts, such as wildfires, that can disrupt the normal delivery of energy. Microgrid technologies are capable of improving a facility's energy resilience and providing additional value. This demonstration of a microgrid at a wastewater treatment plant developed a case study on the employing a microgrid at a wastewater treatment plant to provide sanitary services and control energy usage to participate in grid energy markets.
Project Innovation
This project upgraded a wastewater treatment plant to use a microgrid with a solar photovoltaic system, energy storage, and a microgrid controller for increased resiliency and to participate in energy markets.
Project Benefits
This project demonstrated that a microgrid at a wastewater treatment plant can operate without compromising water quality or negatively affecting plant operations. The EPIC funds demonstrated a functional microgrid by integrating energy storage, on-site generation, and control components and improved resilience.
Affordability
This project used on site microgrid resources to reduce operating costs at the wastewater treatment facility by participating in the demand reduction energy market.
