Sentiment

Score: 4

Explanation: While a rate increase was secured, the final terms are substantially less favorable than the initial request, particularly regarding the revenue increase and return on equity. The settlement provides some certainty but at a lower financial benefit than sought.

Positives

• Secured an approximate $40 million annual customer rate increase, which will boost revenues.
• Support for increasing annual storm reserve funding from $3 million to $6 million, enhancing financial resilience against weather events.
• Support for a pension cost rider, which will help minimize future volatility in pension expenses.
• The settlement resolves all revenue requirement issues in the base rate proceeding, providing clarity and reducing uncertainty.

Negatives

• The approved annual revenue increase of $40 million is significantly lower than the originally requested $75 million.
• The agreed-upon return on equity (ROE) of 9.99% is lower than the initially requested 10.85%.
• The South Carolina retail rate base was settled at $2.2 billion, lower than the originally filed $2.3 billion.
• Agreement to flow back $10 million annually in Production Tax Credits (PTCs) to South Carolina retail customers, reducing immediate revenue.

Risks

• The Stipulation is subject to the review and approval of the Public Service Commission of South Carolina (PSCSC), meaning the terms are not yet final.
• Actual results may be materially different from suggested outcomes in forward-looking statements due to various factors.

Future Outlook

The Stipulation is subject to review and approval by the PSCSC, with new rates requested to go into effect no later than February 1, 2026. In 2028, the Production Tax Credit (PTC) rider will shift to a four-year amortization of PTCs actually earned and monetized, less costs to achieve and amounts already included in the rider.

Industry Context

This partial settlement reflects the ongoing regulatory environment for utility companies, where rate increases are subject to negotiation and approval by state public service commissions. The inclusion of Production Tax Credits (PTCs) and their flow-back to customers highlights the impact of federal incentives like the Inflation Reduction Act on utility rate structures and customer costs. The focus on storm reserves and pension cost riders indicates a broader industry trend towards managing operational risks and long-term financial stability within regulated frameworks.

Legal Proceedings

• The base rate proceeding filed with the Public Service Commission of South Carolina (PSCSC) on June 12, 2025, is an ongoing regulatory matter.
• An evidentiary hearing to review the Stipulation and remaining issues commenced on October 29, 2025.

Stakeholder Impact

• Shareholders: Will see a lower revenue increase and ROE than initially sought, potentially impacting future earnings and dividends, but the settlement provides regulatory certainty.
• Customers: Will face an average 6.5% rate increase, but this is lower than the initially proposed 12.1% increase, and they will benefit from $10 million in annual Production Tax Credit (PTC) flow-back.
• Regulators (PSCSC): Are actively involved in reviewing and approving the partial settlement, ensuring fair rates for customers while allowing the utility to recover costs and earn a reasonable return.

Next Steps

• The Public Service Commission of South Carolina (PSCSC) will review and approve the Stipulation.
• An evidentiary hearing to review the Stipulation and remaining issues commenced on October 29, 2025.
• New rates are requested to go into effect no later than February 1, 2026.
• In 2028, the Production Tax Credit (PTC) rider will shift to a four-year amortization of PTCs actually earned and monetized.

Key Dates

Recommendation

The partial settlement provides regulatory clarity for Duke Energy Progress, securing a rate increase and an approved return on equity. However, the terms are less favorable than the initial request, with a significantly lower revenue increase and ROE. While the settlement removes some uncertainty, the reduced financial upside compared to the original filing suggests a neutral to slightly negative short-term impact on earnings expectations. Investors should hold and monitor the final PSCSC approval and future financial guidance.
