Frequently Asked Questions

The KPSC's final order allows Kentucky American Water, a subsidiary of AWK, to implement an $18.2 million annualized increase in water system revenues, plus $9.9 million in infrastructure surcharges. This is expected to positively impact AWK's overall financial performance, particularly in its Kentucky operations.

Kentucky American Water requested the rate increase primarily to recover approximately $212 million in capital investments made and planned for its water system between February 2025 and December 2026. The KPSC approved a substantial portion of this request, authorizing an $18.2 million revenue increase and a higher rate base.

The termination of the QIP rider means that the costs and investments associated with the program will now be recovered through the approved base rates, rather than a separate surcharge. For customers, this might mean a more consolidated water bill. For the company, it simplifies the rate structure and ensures ongoing recovery of infrastructure investments.

The authorized rate base has increased significantly to $667.0 million, up from $489.4 million in the last rate case. However, the authorized return on equity (ROE) remains stable at 9.70%.
