Kentucky report: Data centers could bring billions, but state must protect ratepayers
A new report from the Kentucky Energy Planning and Inventory Commission (EPIC) highlights Kentucky's strong position for data center investment due to low electricity rates and resources. However, it warns that the state must establish clear rules upfront to prevent existing utility customers from bearing the costs of necessary infrastructure upgrades for these energy-intensive facilities. The report emphasizes the need for proper cost allocation to ensure reliability and fair pricing.
A policy analysis by the Kentucky Energy Planning and Inventory Commission (EPIC) suggests that Kentucky is well-suited for data center investment, citing advantages such as low industrial electricity rates, available land, abundant water, and expanding fiber infrastructure. The report, however, issues a critical warning that without clear regulatory rules for cost allocation, existing electric customers could end up paying for the costly infrastructure upgrades required by large data centers.
EPIC's core concern is how to integrate data centers into the state's electric system without burdening other customers or compromising grid reliability. Data centers operate continuously and demand substantial amounts of electricity for servers, cooling, and redundancy. The commission notes a rapidly growing development pipeline across multiple utility territories, highlighting a planned hyperscale campus in southwest Louisville, announced for January 2025.
The Louisville project, served by LG&E, initially secured 335 MW, later expanding to 402 MW, with a projected lifetime investment of around $11 billion. The first 130 MW phase is targeted for late 2026. As a regulated, vertically integrated utility state, Kentucky utilities have an obligation to serve customers, which may necessitate building new generation, substations, or transmission upgrades for large loads.
EPIC stresses that if these investments enter the utility rate base, costs could be recovered from customers over decades through electric bills. To prevent this, tariffs and contracts must be structured to ensure the new data center loads pay for the infrastructure they trigger. The commission's repeated point is that cost allocation rules must be established before major investments are approved, as regulators have limited tools to reassign costs once projects are deemed "used and useful."
