Exelon Corp.

In the utilities sector, Exelon used most of its water in offices, and office-facility efficiency, stormwater management, and erosion and sediment control were the primary focuses of the utility's water stewardship strategy. Local watersheds are also part of the utility's initiatives for the construction and installation of infrastructure.

Exelon's utility property stormwater management includes green infrastructure, such as rain gardens, native meadows, green roofs, stormwater basins, and infiltration vaults. It also involves field inspections of erosion and sediment control, including independent inspections at projects that may not require regulatory permits. One of the 2025 initiatives involved its utility, BGE, which used flocculent boom socks at a construction site instead of a typical stormwater-treatment system, lowering project costs by about US$800,000 and enhancing water turbidity. At its offices, Exelon installs low-flow toilets and touchless sinks during new construction, renovation, or upgrade projects.
