Duke Energy Gains South Carolina Gas Plant Approval, Incremental to Capex but Core Thesis Unchanged Amid North Carolina Regulatory Overhang

What happened

South Carolina regulators have approved Duke Energy's proposal to build a new natural gas combined-cycle plant in Anderson County, with construction starting in summer 2027 and service by early 2031. This aligns with Duke's $103 billion five-year capital expenditure plan to meet growing energy demand, particularly from data centers, as outlined in the DeepValue report. However, the report emphasizes that Duke's equity value hinges critically on North Carolina's multi-year rate plan outcomes, which face regulatory and affordability challenges. The South Carolina approval, while positive for long-term rate base growth, does not address the imminent risks of delayed rate recovery or lower allowed returns in North Carolina that could strain financing. Thus, this news supports Duke's growth narrative but leaves the investment thesis dependent on unresolved regulatory milestones in its core Carolinas markets.

Implication

Investors should see this approval as a step in executing Duke's capital plan, adding future rate base in South Carolina post-2031. It reinforces Duke's ability to advance projects in supportive jurisdictions, contributing to earnings visibility. However, the DeepValue report highlights that near-term upside requires de-risking North Carolina's multi-year rate plan, where delays or unfavorable outcomes could impair cash flow and increase financing needs. This news does not alter the 'WAIT' rating, as the stock's valuation remains tied to regulatory clarity in North Carolina rather than isolated project approvals. Therefore, maintain a cautious stance, focusing on upcoming North Carolina regulatory events as key catalysts.

Thesis delta

No material shift in the investment thesis; the South Carolina approval is consistent with Duke's growth strategy but does not address the gating regulatory risks in North Carolina that drive the equity story. Investors should continue to prioritize monitoring the North Carolina MYRP timeline and data-center load growth, as these remain the primary determinants of value.
