NOTICE OF FILING Application of Duke Energy Progress, LLC to Establish a New Cost Recovery and Incentive Mechanism for Demand-Side Management and Energy Efficiency Programs (See Docket No. 2024-303-E) - Docket No. 2015-163-E Application of Duke Energy Progress, LLC for Approval of a Modification to Its Existing EnergyWise for Business Program (See Docket No. 2024-303-E) Docket No. 2022-299-E Why is this Notice Important? • This Notice is for electric customers of Duke Energy Progress, LLC (“DEP” or the “Company”) and interested persons. The Company filed an Application on October 13, 2025, seeking approval of two new demand response (“DR”) programs and related administrative modifications to two other programs with the Public Service Commission of South Carolina (“Commission”). The Commission decides whether these proposals will be approved. What is the Company asking the Commission to approve? • The Company’s Application requests that the Commission approve the following: o New DR Programs: o The Company is requesting approval of a new DR program entitled NonResidential Storage Demand Response Program (the “Storage DR Program”). o The Company is requesting approval of a new DR program entitled PowerShare® Nonresidential Load Curtailment Program (the “PowerShare Program”). • Administrative Modifications: o The Company seeks to terminate its Demand Response Automation Rider (“Rider DRA”) offering upon implementation of the PowerShare Program. • The Company is requesting limited modifications to its EnergyWise for Business Rider (the “Rider EWB”). Why is the Company Requesting These Approvals? • This suite of proposals is directly responsive to stakeholder feedback. An overview of each proposal is outlined below. Additional details are included in the Company’s Application. o Storage DR Program: • The Company designed the Storage DR Program to increase participation in, and expand the benefits of, energy dispatch across commercial, industrial, governmental, and other non- residential customer groups. • This program offers incentives to non-residential customers that make their energy storage system available for the Company to control (i.e., charge, discharge, or store energy) during certain DR events (a minimum level of 30 control events a year and a maximum of 36 control events annually for up to 4 hours during each event). • In return, customers will be paid certain incentives, including a monthly capacity credit and an energy credit, for the energy dispatched from their installed equipment during such event(s). o PowerShare Program: • The PowerShare Program offers incentives to non-residential customers that effectively manage their energy consumption, thereby providing the Company with a source of capacity across the entire year through load reduction. • The program provides tiered notification windows along with corresponding tiered incentive levels. The Company also proposes to incorporate an automatic control option, which would allow customers to automatically curtail their load upon notification from the Company. o PubAlicd Smervinicies Ctormatmivisesi oMn oof dSoiufithc aCatirolninsa: • Attention: Clerk’s Office • 101 Executive Center Drive, Suite 100 • Columbia, SC 29210 • The Company is requesting to terminate its Rider DRA offering upon full implementation of the PowerShare Program because Rider DRA does not effectively address the Company’s need for more DR resources in the winter season that would reduce the Company’s system peak. The Company believes that the PowerShare Program would effectively address that need and would attract many of the same customers participating in the Rider DRA. • Finally, the Company is requesting a limited modification to Rider EWB to reflect closure of Rider DRA. The Company is proposing no other changes to Rider EWB. The Company’s Application states that the Storage DR Program and the PowerShare Program are cost- effective under the Utility Cost Test, Total Resource Cost Test, and the Ratepayer Impact Measure Test. The Company is not seeking an increase in rates at this time. These requests were filed according to S.C. Code Ann. Section 58-27-820, S.C. Code Ann. Sections 58-37-10 et seq. and S.C. Code Ann. Regs. 103-823, Order No. 2024-445, Order No. 2021-33, Order No. 2025-669 and the Rules of Practice and Procedure of the Commission.
