Large Load Tariff Filing
Caution Regarding Forward-Looking Information
Certain statements included on this website landing page are forward-looking. The words "will", "would", "expects", “aims”, “intends” (and grammatical variations of such terms) and similar expressions are often intended to identify forward-looking statements, although not all forward-looking statements contain these identifying words. Specific forward-looking statements in the information below include but are not limited to statements regarding customer protections, supporting responsible growth, financial safeguards, transparent rules, and cost-allocating principles. These statements are based on factors or assumptions that were applied in drawing a conclusion or making a forecast or projection, including assumptions based on historical trends, current conditions, and expected future developments. Since forward-looking statements relate to future events and conditions, by their very nature they require making assumptions and involve inherent risks and uncertainties. Liberty cautions that although it is believed that the assumptions are reasonable in the circumstances, these risks and uncertainties give rise to the possibility that actual results may differ materially from the expectations set out in the forward-looking statements. Given these risks, undue reliance should not be placed on these forward-looking statements, which apply only as of their dates. Other than specifically required by law, Liberty undertakes no obligation to update any forward-looking statements to reflect new information, subsequent or otherwise.
Protecting Existing Customers; Serving Large Energy Users
Liberty’s Large Load tariff, filed for review and approval by the Missouri Public Service Commission on September 11, 2026, aims to establish clear guardrails that protect existing customers, prioritize reliability, and support responsible growth through transparent rules and cost-allocation principles.
Key Protections for Existing Customers
Liberty’s proposed tariff includes key protections for existing customers. These safeguards are designed to help protect existing customers by making Large Load customers accountable for long-term obligations associated with service, even if plans change or service ends early.
Large Load customers pay their own way
- This includes the infrastructure and incremental generation, transmission, interconnection, energy, and related costs needed to serve them.
- Liberty proposes that these costs be directly assigned to Large Load customers rather than broadly allocated to other customer classes.
- This approach promotes transparent cost allocation and recovery while helping protect existing customers from costs associated with serving new Large Load facilities.
Financial safeguards and stability
Under the proposal, Large Load customers will be required to:
- Pay minimum monthly bills if they use less electricity than planned
- Meet strict credit requirements
- Enter into long-term service agreements with a minimum term and an obligation to pay an exit fee for any failure to fulfil such minimum term
Protecting reliability
- The proposed tariff preserves Liberty’s ability to curtail Large Load customers during regional or local reliability emergencies.
- Additional provisions, including contract capacity requirements, reserve margin considerations, and load forecasting obligations, are designed to help promote safe and reliable service for all customers.
Supporting Responsible Growth
The proposed tariff seeks to establish a transparent and consistent framework for evaluating and serving prospective Large Load customers. By clearly defining cost allocation responsibilities, recovery mechanisms, and existing customer safeguards, the proposal aims to support economic development opportunities while establishing requirements designed to protect existing customers and support reliable service.
“We believe our Large Load tariff filing appropriately balances our obligation as a regulated utility to serve both existing and future customers while establishing clear financial and reliability protections. When growth can be accomplished in a manner that is fair to existing customers and supportive of reliable electric service, we believe it can create meaningful benefits for the communities we serve.”
— Aaron Doll, Liberty Vice President, Energy Supply Services
