Industrial Customers
Santee Cooper completed a months-long public comment process so that customers and others could review and provide input on the proposed changes.
On Oct. 30, 2026, the Santee Cooper Board of Directors approved an average 3.3% increase across its retail customer classes in 2027, paired with rate structure updates shaped by customer feedback. Another overall average increase of 3.1% will take effect in 2028.
Industrial Rate Changes
The 2027 adjustment for industrial customers is a 2.6% increase, and the 2028 adjustment is a 2.1% increase. Santee Cooper held several customer focus groups earlier this year, and these rates incorporate customer feedback from those sessions.
Revised industrial customer rates also include a High Impact Load Rate, which builds on and transitions the 2025 Experimental Large Load Rate Santee Cooper into a standard offering. This rate will collect payment up front from high impact load customers, such as data centers, for upgrades to our system necessary to power these loads. Front-loading these payments means the entities causing the expenses will also be the entities paying for the expenses, which protects our other customers from the cost impacts caused by large loads.
