Florida rejects Duke’s large-load tariff as filed
Contract protections still need a cost-supported rate.

The quick read
The Florida Public Service Commission rejected Duke Energy Florida’s proposed large-load tariff as filed November 3. Its approved recommendation says the plan excluded some qualifying customers and did not adequately show that existing rates plus contract safeguards would make each large user pay its full service cost. Duke argued a base-rate freeze and shareholder commitments protected other customers. The commission required a new filing with cost support. This is a decision about proposed payment rules—not an observed household saving, a statewide construction ban or proof every data center shifts costs.
Protecting neighbors is only half the test
Duke’s position, as reproduced in the staff record, was that its existing base-rate freeze through 2027 and proposed contract safeguards protected other customers. Staff agreed that shareholder absorption of unrecovered costs offered protection during that period. But protecting neighbors temporarily does not itself show that each large-load customer pays its full service cost. The approved recommendation found that showing inadequate. This is a finding about the proposal’s evidence, not a measured subsidy assigned to every facility. (Sources 1–2)
Interruptible demand still counts
Staff read the new law’s large-load definition as covering qualifying customers with anticipated monthly peaks of at least 50 megawatts, whether their service is firm or interruptible. Duke argued that different service profiles carry different planning and investment risks. The approved recommendation rejected excluding qualifying non-firm customers and required a filing covering all customers within the statutory definition, with a proposed large-load rate schedule and adequate cost support. The October 29 modification changed permission to refile into a requirement for commission approval. (Sources 1–3)
A different decision is not a household-bill comparison
Oregon’s separately dated PGE decision approved class-average rate changes effective July 8; Florida rejected this proposed framework. Those are different regulatory outcomes, not matched observations of what identical households paid. The Oregon package also changed power costs and other charges, so it cannot isolate data centers’ contribution to a bill change. (Sources 4)
The practical question is who must pay which costs under the next approved terms. Contract assurances matter. The cost evidence has to arrive too.
What this record cannot settle
A tariff-compliance decision, not legal advice, a new operating-data census or a calculated household benefit. Complete utility/intervenor briefs and individual contracts were not independently audited. Florida and Oregon differ in utility, service territory, timing and rate components; no matched or causal household-bill comparison is established.
