Duke Energy Seeks NC Rate Hikes to Fund Reliability, Growth Investments

Duke Energy filed with the North Carolina Utilities Commission for rate hikes to recoup about $800 million in fuel and purchased power costs from an extreme cold snap in late January and early February. The filing seeks $500 million for its Duke Energy Carolinas division and $309 million for Duke Energy Progress, driven by a record winter peak of 37,308 megawatt-hours on Jan. 27—the highest ever on Duke's Carolinas system. To meet surging demand, the utility bought electricity from neighboring providers at sky-high market prices, passing through costs without markup.[1] Residential customers face an average monthly bill increase of just under $7 starting June 1, pending approval, as Duke cites rising energy costs amid prolonged cold weather that spiked usage far beyond rate adjustments. While a prior small rate bump added only about $4 to a 1,000 kWh bill for Duke Energy Carolinas users and less than $1 for Progress customers, winter bills soared primarily from higher consumption.[1][2] Duke notes over $95 million in 2025 assistance reached nearly 110,800 North Carolina households via programs like Share the Light Fund and federal LIHEAP.[2] Beyond recovery, Duke proposes multi-year investments to enhance reliability and fuel North Carolina's growth, including phased hikes like $6.59 monthly for residential users on Jan. 1, 2028, after an initial jump effective Jan. 1, 2027. Commercial customers could see 9.2% and 4.6% average increases over 2027-2028, targeting grid upgrades for booming regions from the Research Triangle to Charlotte's tech corridor.[3] The push aligns with state mandates for cleaner energy, though specifics on solar and wind tie-ins remain tied to broader carbon reduction goals.
