Purchased Water Adjustment Clause (PWAC)

The Purchased Water Adjustment Clause application offers a utility the ability to file for a water rate adjustment based on a rate increase from its wholesale supplier.  A utility must request the Public Service Commission of Wisconsin (PSC) to authorize a PWAC rate change within 90 days of a change in its wholesale supplier's rates and only when the wholesaler's rates are adjusted through the conventional rate case process or forfeit all adjustments to its rates under the PWAC until the time of its next rate case.  A utility must file the application using the PSC's Electronic Records Filing (ERF) system.
