Interest On Deposits - Current

Announcement made December 1, 2025

In accordance with revisions made to KRS 278.460 in the 2012 session of the Kentucky General Assembly, the Public Service Commission has calculated the annual interest rate to be paid on customer deposits for the upcoming year.

The statute requires the Commission to calculate the interest rate to be paid on an annual basis by averaging the one (1) year constant maturity treasury rate from September, October, and November of each year.

The Commission determines the rate and posts it to the website: https://psc.ky.gov no later than December 15 of each year.

Using data from September, October, and November of 2025, the Commission has calculated an interest rate of 3.64% to be paid on customer deposits for the 2026 calendar year.

As in the past, we prepared a set of Frequently Asked Questions as well as a copy of the revised statute which are included in the links below.
