Duke Energy Florida large-load tariff

Duke filed revised large-load tariff and contract protections after withdrawing its earlier proposal.

Open proceeding

Why it matters

The proposed 50 MW framework is not effective unless and until the FPSC approves it.

Proposed terms

Key requirements

Eligibility threshold

50 MW firm load

The April 2026 petition proposes coverage when firm load reaches 50 MW at any time during the contract term.

Minimum payment

75%–85% of contract demand plus a 60% load-factor floor

The proposed LLCA combines a take-or-pay demand percentage with a minimum billing-energy volume.

Minimum contract term

20 years

The proposed initial contract term is twenty years, with the customer-specific ramp schedule documented in the agreement.

Service structure: Existing general-service rate plus mandatory LLCP and LLCAProposedLarge-load customers would remain on GSD-1 or GSDT-1 until a dedicated rate is considered in Duke's next rate case.
Credit and collateral: Letter of credit, cash, or parent guarantyProposedSecurity is risk-based; a letter-of-credit issuer must meet A-/A3 standards, and at least 10% security applies when the relevant obligation exceeds $100 million.
Exit protection: Two-year notice plus make-whole obligationsProposedAfter service begins, termination exposure includes three years of minimum monthly bills and the net book value of customer-specific facilities, adjusted for refundable contributions.
Grid infrastructure: Full CIAC paid before constructionProposedThe proposal requires upfront customer funding of customer-caused facilities, refundable over up to five years based on base revenues.
Reporting and true-up: Security, cost, and CIAC obligations reconcile to actual exposureProposedThe agreement updates the security percentage and refundable contribution as project risk and delivered revenues change.
