About

Duke Energy is one of the largest regulated utilities in the United States with approximately $29 billion in annual revenue, managing a generation fleet spanning nuclear, natural gas, coal (transitioning to retirement), solar, and wind across a 100,000-square-mile service territory. CEO Lynn Good, who has led Duke Energy since 2013, filed the company's 2025 Carolinas Resource Plan responding to unprecedented load growth — North Carolina attracted $19 billion in announced business investments and 25,000+ new jobs in 2025 alone, driven by semiconductor manufacturing, data center construction, and electric vehicle manufacturing — resulting in electricity demand growth projections 8x greater than the prior 15-year trend. The plan calls for 4,000 megawatts of solar capacity by 2034 and battery storage expansion to 5,600 megawatts by 2034 (+2,900 MW from current levels).
