Modeled rates

Duke Energy Progress' South Carolina large-service schedule for the Florence–Sumter Pee Dee region: the cheap-energy/heavy-demand side of the Duke pair. Figures fold the June-2026 rider summary — a net credit — and the 6% electricity sales tax. Rates carry the currently effective leaf; a filed annual-review increase of about 6.2% for commercial classes takes effect August 2026, and the library re-derives the row at that date. A fixed monthly customer charge and two small filed adders are not modeled.
