Frequently Asked Questions


  • A base rate case is a public regulatory review process where a utility must demonstrate to the Kentucky Public Service Commission (KYPSC) why a proposed increase in rates is needed. This independent, public process helps ensure transparency and fair rates based on the costs to serve our customers.
  • We work hard every day to keep costs reasonable for our customers and to avoid an increase to customer bills whenever possible. Recent work to modernize power plants, generate cleaner power, modernize  how we manage coal ash and improve reliability while enabling more options for customers has made it necessary for Duke Energy to seek a change to customer bills to pay for these important investments.
  • For decades, reliable, affordable electricity in this state was made possible by coal. With coal came coal ash – the byproduct of decades of generating electricity from this resource. It’s a waste that was produced each time we turned on a light switch, watched a television or charged a mobile phone. In fact, a typical residential family today will generate several hundred pounds of coal ash each year from consuming electricity to meet its household needs. 

    But like any waste, we must ensure that coal ash is responsibly managed. As your local electric provider, it’s our job to take care of the waste, and we will do it responsibly. But the cost of that service is a responsibility we all share as consumers of electricity, so that the public and the environment are protected now and in the future.
  • Duke Energy Kentucky is obligated to provide every customer in our service area with reliable electricity at rates approved by the KYPSC. In exchange, the utility is allowed the opportunity to earn a fair return for investors. Even though our regulators will ultimately determine any changes to customer bills, we pledge to do our part to keep rates as reasonable as possible.
  • First, Duke Energy Kentucky must demonstrate to the KYPSC why the rate increase is needed. The Kentucky Attorney General and other interested stakeholders audit our filings and vet the company’s request. The commission then thoroughly reviews our request. Later this year, or early next year, the commission will conduct a hearing and consider our written and oral testimony, along with viewpoints from others representing customer groups and other stakeholders. We expect a decision by spring 2018. Duke Energy Kentucky has requested that new rates, as approved by the KYPSC, go into effect spring 2018.
  • It’s important to us to give our customers more options to help them better manage energy and ultimately save money – so we’re connecting with our customers through new tools like usage updates, free home energy audits and a menu of energy-saving tips, programs and incentives for every budget.

    We’re also proud to provide support to those customers who need it most through initiatives like the Neighborhood Energy Saver Program, which provides energy-saving upgrades at no cost to income-qualified homeowners.
  • Smart meters give customers more control and information about their daily energy use. This will enable automated meter reading, remote connects/disconnects and quicker outage detection. Additionally, smart meters are the one piece of technology necessary to enable more energy-saving, bill-lowering tools for customers. Deployment in Kentucky is beginning late summer and should be complete by December 2018.
