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.

Since 1 August 2025 (HB 7031), the data centre sales tax exemption requires at least 100 MW of critical IT load and US$150 million of investment, and smaller existing sites lose it at their next five-year review. SB 484, the Hyperscale Data Center Act (2025), sets the utility connection and cost-allocation rules for large loads, and a 2026 law preserves local authority to reject facilities and adds water safeguards.
Figures compiled from the Edison Electric Institute's "Large Load Projects and Tariffs" (September 2026) member-company summary and public regulatory filings. Confirm current tariff terms directly with Florida Power & Light and the relevant state public utility commission before relying on any figure for a capital decision.
