The state&rsquo;s main 2026 change is Dominion Energy South Carolina&rsquo;s rate increase, which regulators approved and which took effect in July.</p> <p>This article covers Dominion Energy South Carolina, which serves more than 820,000 households. It does not cover Duke Energy&rsquo;s two South Carolina utilities, Santee Cooper or the electric cooperatives.</p> <h2 id="quick-summary">Quick Summary</h2> <table> <thead> <tr> <th></th> <th>Original request</th> <th>Settlement (May 8, 2026)</th> </tr> </thead> <tbody> <tr> <td>Increase</td> <td>12.7%</td> <td>7.6%</td> </tr> <tr> <td>Annual revenue</td> <td>$322 million</td> <td>$207 million</td> </tr> <tr> <td>Bill change at 1,000 kWh</td> <td>About +$20 a month</td> <td>About +$12 a month</td> </tr> <tr> <td>Return on equity</td> <td>10.5%</td> <td>9.9%</td> </tr> <tr> <td>Start</td> <td>July 2026</td> <td>First billing cycle of July 2026 (approved)</td> </tr> </tbody> </table> <h2 id="what-the-settlement-says">What the Settlement Says</h2> <ul> <li><strong>Bills:</strong> a residential bill at 1,000 kWh would go from about $157 to about $169.</li> <li><strong>Revenue:</strong> $207 million a year, $115 million less than requested.</li> <li><strong>Return on equity:</strong> 9.9%. It was 9.94% before the case, and Dominion asked for 10.5%.</li> <li><strong>Relief:</strong> $3 million from shareholders to reduce bills in the first year, and $1 million a year for three years for low-income assistance and weatherization.</li> </ul> <p><strong>Our math:</strong> $12 ÷ $157 = 7.6%, which matches the reported percentage.</p>
