Insights
Duke Energy proposes 7.7% rate increase in South Carolina to recover grid investments that have already improved reliability and storm resilience.
Duke Energy Carolinas has filed a request with South Carolina regulators seeking a $150.5 million annual revenue increase, representing a 7.7% increase over current revenues. This rate case comes approximately 18 months after their previous filing in early 2024, indicating a relatively aggressive rate case cadence that could support financial stability.
Breaking down the impact, residential customers using 1,000 kWh monthly would see bills increase by $10.38, from $136.82 to $147.19 – a 7.6% increase. Commercial and industrial customers face more modest increases of 5.4% and 5.2% respectively, suggesting a cost allocation that places somewhat heavier burden on residential ratepayers.
The proposed effective date of March 1, 2026 provides regulatory runway and predictability for investors. The filing focuses on recovering costs for completed investments rather than forward-looking expenditures, which typically faces less regulatory scrutiny and improves approval prospects.
The company highlights tangible benefits from previous grid investments, specifically noting that during Hurricane Helene, smart self-healing technology automatically restored over 35,000 customer outages and saved more than 153,000 hours of total outage time. This demonstrates concrete reliability improvements that regulators tend to view favorably when considering rate increases.
This rate case reinforces Duke's focus on grid modernization and reliability improvements while maintaining its regulated utility business model. The company serves nearly 680,000 retail electric customers across 18 counties in South Carolina, making this a significant component of Duke Energy Carolinas' overall business, which totals 2.9 million customers across both Carolinas.

$10.38 $136.82 $147.19 5.4% and industrial customers will see an average increase of around5.2% . The amount of increase per customer class can vary based upon how much more additional revenue is needed to ensure that the class is covering the cost to serve them.

- This proposal reflects the investments we have made to strengthen the grid, improve storm readiness, maintain and enhance our generating fleet and serve a growing customer base.
- It also reflects how the company is doing that work: with discipline, with a focus on operational excellence, and with a thoughtful approach to how and when we seek rate adjustments.
Investments in action: The company's grid investments have positioned it well for storm response.
- For example, as Hurricane Helene made its way across the Carolinas, grid improvements were already helping to combat power outages from the storm.
- Smart, self-healing technology installed across the Duke Energy Carolinas service territory helped to automatically restore more than 35,000 customer outages and saved more than 153,000 hours of total outage time, showing the value of the self-healing programs.

- "We know families and businesses are juggling a lot and we do not take a request to increase rates lightly but being upfront and timely with our request is the right thing to do and in the best interest of our customers." – Tim Pearson, Duke Energy's
South Carolina president
