Should local utility companies be allowed to frequently increase rates to fund infrastructure projects?
Kentucky American Water has requested rate increases of up to 20% for industrial customers and 19.5% for commercial accounts to support over $100 million in water system projects. The proposed adjustments, which would also raise residential rates by nearly 16%, are expected to take effect in mid-December 2026.
Why it matters
The proposed hikes represent a significant increase in overhead costs for businesses that rely on the utility, following a prior rate adjustment approved in December 2025. Operators must now factor these potential utility cost spikes into their 2027 budget planning.
Commercial customers face a 19.5% rate hike, while industrial accounts are slated for a 20% increase to fund $100 million in system-wide infrastructure projects. This request follows a December 2025 approval that authorized rate hikes for $200 million in prior investments.
The players
Kentucky American Water
A regulated utility provider responsible for water infrastructure and services across parts of Kentucky.
Public Service Commission
The state regulatory agency that oversees utility rates and construction compliance for Kentucky businesses.
Lexington
A major Kentucky municipality currently involved in a dispute over utility-led construction projects.
The details
The utility submitted a formal request for these adjustments to the state Public Service Commission to recover costs associated with extensive water system upgrades. This follows an August 2026 complaint filed by Lexington officials regarding ongoing utility construction projects. The commission is currently reviewing the proposal and will hold a public comment session at its Frankfort headquarters to evaluate the impact on local ratepayers.
Timeline
December 2025: PSC approved a previous rate increase.
August 2026: Lexington filed a complaint regarding construction projects.
October 13, 2026: Public Service Commission hosts public comment session.
Mid-December 2026: Proposed rate increases would become effective.
Market Landscape
The current rate hike request follows the precedent set by the December 2025 PSC approval for $200 million in system investments. These recurring increases reflect a broader trend of capital-intensive infrastructure upgrades being passed on to commercial and residential ratepayers.
Business owners should review their utility expense forecasts to account for a potential 19.5% rise in water costs beginning in late 2026. Consult with your accountant to determine how these adjustments will impact your variable operating expenses for the upcoming fiscal year.
The takeaway
The proposed rate hikes underscore the importance of monitoring regulatory dockets for infrastructure-related cost pass-throughs. Businesses interested in providing feedback on these costs should prepare to participate in the October 13, 2026, hearing at the Public Service Commission headquarters.
