Every figure above comes from the same power-cost and tariff dataset behind the SCR AI Build Configurator — a licensed, embeddable widget that models seven data centre build configurations against all nine Canadian provinces and all 50 US states plus DC, returning capital expenditure by line item, energy cost, revenue by commercial structure, EBITDA and payback.

Frequently Asked Questions

What is KU/LG&E's Extremely High Load Factor Service Tariff?

Customers with an extremely high, continuous load factor qualify for a new Extremely High Load Factor Service tariff, approved in February 2026 as part of KU and LG&E's larger rate reviews. Kentucky Power separately received approval in March 2025 for changes to its industrial general service tariff (Case No. 2024-00305).

Why did Kentucky Utilities and Louisville Gas and Electric (PPL) introduce this large-load structure?

To ensure the cost of new generation, transmission and distribution infrastructure built to serve very large customers, chiefly hyperscale data centres, is paid for by those customers rather than spread across the general rate base of residential and small commercial ratepayers.

What large data centre projects are already active in Kentucky?

Kentucky's live pipeline includes a 1 GW TeraWulf data centre project at the Muskie Data Campus in eastern Kentucky and a 400 MW PowerHouse Data Centers campus in Louisville.

Does this tariff replace Kentucky's standard commercial and industrial rates?

No. KU/LG&E's Extremely High Load Factor Service Tariff sits above Kentucky Utilities and Louisville Gas and Electric (PPL)'s standard commercial and industrial rate schedules and applies specifically to customers that meet or exceed the large-load threshold described above. Smaller commercial and industrial loads continue to be billed under existing rate schedules.

How can I model a Kentucky data centre build against this tariff and other states?

The SCR AI Build Configurator applies Kentucky's power cost, tax treatment and large-load tariff rules alongside all other US states and Canadian provinces, so a Kentucky scenario can be compared line-by-line against any alternative site.
