Duke Energy Carolinas SC Rate Case

DE Carolinas Rate Case

Building a cleaner, smarter energy future for South Carolina

Rate Case Update

On May 1, 2019, the Public Service Commission of South Carolina (PSCSC) conducted a verbal vote on the Duke Energy Carolinas rate increase request during their regular agenda meeting. On May 21, the PSCSC issued a detailed written order explaining their decisions in the case. New rates will be effective beginning June 1, 2019.

The changes in customer rates come after a lengthy and very public process evaluating a request that is at the heart of the company's ability to build a smarter energy infrastructure for South Carolina. The changes also reflect the company's efforts to deliver electricity that is cleaner than ever, and ensure the best customer service possible. The changes also include savings from recent federal tax reform.

The PSCSC approved an average rate increase of 3.7% for all residential customers. Commercial and industrial customers will see an average increase of around 1.6% (actual rates vary by customer class and size).

Beginning June 1, a typical residential customer who uses 1,000 kilowatt-hours (kWh) of electricity monthly would pay about $122.45 per month, an increase of about $4.71.
