North Carolina Regulators Reject Duke Energy's $584 Million Gas Turbine Plan

North Carolina regulators have formally denied Duke Energy’s proposal to construct a $584 million natural gas turbine near Hamlet. The North Carolina Utilities Commission concluded that the utility failed to demonstrate that the project is currently needed or to adequately explain how existing customers would be shielded from the associated costs. This decision halts the proposed expansion of the Sherwood H. Smith Energy Complex, forcing Duke to gather more evidence before it can reapply.

The rejected plan involved adding a turbine capable of generating approximately 255 megawatts of electricity by 2030. The site is adjacent to the location of Amazon’s planned $10 billion data center campus in Richmond County. While the commission did not explicitly rule that the turbine would serve Amazon, it noted that much of the anticipated demand growth is linked to future data centers. The regulators emphasized that approving such an expensive infrastructure project before establishing clear necessity would expose ratepayers to significant financial risk.

Regulatory Cautions on Data Center Demand

The commission’s order highlights uncertainty regarding Duke’s demand forecasts. Regulators stated that their review of the utility’s projections is incomplete and that approving the turbine prematurely could lead to customers paying for capacity that may not deliver sufficient value. This stance reflects a broader scrutiny of large-scale data center expansions and their impact on regional grid reliability and cost structures.

Duke Energy has previously asserted that large customers, including data centers, bear the direct costs of connecting to the grid. However, the company acknowledged that power plant costs are shared among customers based on usage and capacity. The utility pointed to contractual protections, such as minimum bills and termination penalties, as safeguards for ratepayers. Despite these assurances, the commission found that Duke did not sufficiently demonstrate how these protections would apply specifically to the new turbine project.

Internal Disagreements and Customer Advocacy

The decision was not unanimous. The Public Staff, which represents customer interests in utility proceedings, recommended approving the turbine despite describing its cost as staggering. One commissioner dissented from the denial, arguing that the project is necessary to maintain grid reliability as electricity demand grows. This divergence underscores the tension between ensuring adequate power supply and protecting consumers from potentially unjustified infrastructure expenditures.

Duke Energy retains the option to reapply for the project. In any future filing, the commission will require detailed explanations on how the project will be financed, the specific proportion of demand tied to data centers, and an analysis of whether alternative resources could provide reliable power at a lower cost. The outcome will likely influence how utilities approach capital investments in regions with rapidly growing data center loads.

Implications for Regional Energy Strategy

This ruling sets a precedent for utility projects in North Carolina, emphasizing the need for robust justification of demand forecasts and cost allocation models. As data centers continue to drive electricity consumption, regulators are likely to demand greater transparency from utilities regarding the economic viability of new generation assets. The focus remains on ensuring that ratepayers are not burdened by speculative infrastructure investments.

For Duke Energy, the denial represents a significant setback in its expansion plans near the Amazon campus. The company must now refine its projections and strengthen its cost-protection arguments to meet the commission’s heightened standards. This episode highlights the evolving regulatory landscape for energy providers serving high-demand industrial customers.
