Commercial Customers
On May 1, 2026, the Santee Cooper Board of Directors received proposed base rate changes for 2027 and 2028 and approved a public comment process, giving customers several months to review the proposed changes and provide input.
Proposed Commercial Rate Changes
For commercial customers, the proposed 2027 base rate adjustment is a 2.9% increase, and the proposed 2028 adjustment is an 2.9% increase. Santee Cooper held several customer focus groups earlier this year, and the proposed rates incorporate feedback from those sessions. Revised rates for small commercial customers change how demand charges are calculated to reduce the impact of isolated spikes in electricity usage on customer bills. Instead of billing demand on a single highest-hour charge regardless of time of day, the new Balanced Demand Billing would include a charge for the average of a customer’s maximum hourly use during the four highest peak periods each month. Additionally, the commercial peak window has been shortened from four hours to three, aligning business peak hours with residential and giving customers more flexibility to manage costs.
Additional Commercial Rate Information
- GA Demand charges are based on the customers’ usage from 6am-9am November-March and 3pm-6pm April-October.
- On-Peak Energy Charges for GA-LL, GB, TP, GV, GT and GT demand are 6am-9am November-March and 3pm-6pm April-October. Off-peak is all other hours.
How You Can Get Involved
Santee Cooper’s residential, commercial, industrial, municipal light and power, and certain wholesale customers have the right to review the proposed rate schedules; appear and speak in person concerning the proposed rates at public meetings or the specified meetings of the Board of Directors; and submit written comments.
