FPL's Large Load Contract Service (LLCS-1 / LLCS-2): What It Means for AI Data Centre Siting in Florida

New or incremental load of 50 MW or more with an 85 percent load factor qualifies for Large Load Contract Service-1 or -2, approved as part of FPL's larger rate review and effective January 1, 2026. Both schedules carry minimum-term, take-or-pay and exit-fee provisions and collateral requirements. Duke Energy Florida has separately filed an updated large-load proposal in response to state law SB 484.

Also active in Florida: Florida's approach is notable for pairing a hard load-factor test (85 percent) with the minimum-term structure, meaning intermittent or highly variable large loads may not qualify for the standard large-load rate at all.

Weighing Florida 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.

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 FPL's Large Load Contract Service (LLCS-1 / LLCS-2)?

New or incremental load of 50 MW or more with an 85 percent load factor qualifies for Large Load Contract Service-1 or -2, approved as part of FPL's larger rate review and effective January 1, 2026. Both schedules carry minimum-term, take-or-pay and exit-fee provisions and collateral requirements. Duke Energy Florida has separately filed an updated large-load proposal in response to state law SB 484.

Why did Florida Power & Light 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 Florida?

Florida's approach is notable for pairing a hard load-factor test (85 percent) with the minimum-term structure, meaning intermittent or highly variable large loads may not qualify for the standard large-load rate at all.

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

No. FPL's Large Load Contract Service (LLCS-1 / LLCS-2) sits above Florida Power & Light'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 Florida data centre build against this tariff and other states?

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