Weighing Alabama against another state or a Canadian province with a different rate and interconnection picture entirely? Run both sides of the comparison through our licensed AI data centre cost configurator — it applies each jurisdiction's actual power rate, tax treatment and large-load tariff rules to the same seven build configurations.

Frequently Asked Questions

What is Alabama Power's Modified Rate BTAL?

Customers larger than 30 MW can be required by Alabama Power to take service under a special contract under the modified Rate BTAL (Business Time Advantage – Large), approved by the Alabama Public Service Commission on January 7, 2025. Special contracts can include minimum billing demand, financial assurance and exit-fee terms.

Why did Alabama Power (Southern Company) 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 Alabama?

Alabama's large-load pipeline includes a $1.5 billion Meta data centre in Montgomery County and, through the Tennessee Valley Authority, a Google data centre expansion in Jackson County backed by up to 50 MW of advanced nuclear generation.

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

No. Alabama Power's Modified Rate BTAL sits above Alabama Power (Southern Company)'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 Alabama data centre build against this tariff and other states?

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