Resilient Energy for Wastewater Infrastructure Grant Program Resilient Energy for Wastewater Infrastructure Grant Program Application period currently OPEN The Resilient Energy for Wastewater Infrastructure (REWI) Grant Program funds the implementation of solar energy and battery storage at publicly owned wastewater treatment plants (WWTPs).
Wastewater infrastructure is vital for maintaining public health, environmental safety, economic stability and overall community functionality. Traditionally designed for reliability, these systems encounter new stressors from hazardous weather, aging assets, cyber threats, and population changes.
Investing in resilient infrastructure not only extends the life of wastewater facilities but also reduces operational costs and enhances community well-being, especially during severe weather events. Key benefits include minimizing service disruptions, managing risks more effectively, and creating more cohesive system-wide planning strategies.
The REWI Grant Program is funded by the U.S. Department of Energy (USDOE) State Energy Program (SEP) from supplemental appropriations authorized under the Infrastructure Investment and Jobs Act (IIJA). Only publicly owned WWTPs in Illinois are eligible for program awards. Applicants must register in the Grant Accountability and Transparency Act (GATA) portal prior to completing an application.
Applications will be scored competitively with scoring to be completed within 90 days of application close. The Notice of Funding Opportunity (NOFO) closes on April 30, 2026 at 5:00 pm (CST). Awards will range from $200,000 to $2,000,000.
