Battery Storage System Guidance for Water and Wastewater Utilities

Battery energy storage systems (BESS) are increasingly being considered by water and wastewater utilities to capture the full energy potential of onsite distributed energy resources (DERs) and achieve cost savings. As new BESS technologies emerge, however, questions about applications, economy of scale, cost-benefits, reliability, maintenance, and durability, continue to emerge. This study provides guidance on various life cycle aspects of BESS projects at water and wastewater utilities, including information on the technologies and resources needed for BESS deployment; reviews the financing models and benefits of BESS projects; and provides case study examples on current BESS implementations in the municipal sector.
