Duke Energy Progress

Summary of Order Issued by the North Carolina Utilities Commission

(Docket E-2 Sub 1219)

Background on rate case filings

On October 30, 2019, Duke Energy Progress (“DEP”) filed a rate case (“2019 Rate Case”) with the North Carolina Utilities Commission (“NCUC”) to request an approximately $464 million net increase in annualized retail revenues. The rate case filing requested a 10.3% return on equity (“ROE”) and a 53% equity component of the capital structure.

An NCUC order in DEP’s prior rate case, filed in 2017, allowed DEP to recover deferred coal ash costs of $234 million (NC retail allocation) over 5 years with a weighted average cost of capital (“WACC”) return. The order was subsequently appealed to the North Carolina Supreme Court (the “Court”). On December 11, 2020, the Court issued an opinion on the consolidated appeals, which upheld the NCUC’s decision to include coal ash costs in the cost of service, and the NCUC’s discretion to allow a return on the unamortized balance of coal ash costs. The opinion also remanded to the NCUC a single issue – to consider the assessment of support for the North Carolina Public Staff’s (“Public Staff”) equitable sharing argument.

Background on settlements reached

On June 2, 2020, DEP and the Public Staff filed an Agreement and Stipulation of Partial Settlement (“First Partial Stipulation”) resolving certain issues in the base rate proceeding, the most significant of which would result in the removal of storm costs from the rate case and an agreement to file a petition seeking to securitize the costs.

On July 31, 2020, DEP and the Public Staff filed documents in support of an agreement in principle reached on additional issues related to the base rate proceeding (“Second Partial Stipulation”), primarily ROE, capital structure, deferral of grid projects, and tax reform.

On September 1, 2020, DEP implemented interim rates consistent with the Second Partial Stipulation. The incorporation of EDIT flowback in the interim rates kept most customers rates unchanged.

On January 22, 2021, DEP, Duke Energy Carolinas, the NC Attorney General’s Office (“AGO”), the Public Staff and Sierra Club entered into a Settlement Agreement (“Coal Ash Settlement”) which addresses all historical coal ash prudence and cost recovery issues, including the 2019 Rate Case, and provides clarity on coal ash cost recovery for the next decade in North Carolina.

On April 16, 2021, the NCUC issued an order approving the First Partial Stipulation, the Second Partial Stipulation and the Coal Ash Settlement without modification. The order also addresses other outstanding items in the case.

Major Components of the Order

Approves the First Partial Stipulation and the Second Partial Stipulation including:

·	ROE of 9.6% based upon a capital structure of 52% equity and 48% debt

·	Deferral treatment for approximately $0.4 billion of Grid Improvement Plan projects including a return

·	Unprotected Federal Excess Deferred Income Taxes (“EDIT”) flow back period of 5 years. See additional EDIT discussion below.

Determination of the reasonableness and prudence of $714 million of storm costs, which have been removed from the rate case. DEP filed a petition seeking to securitize the costs on October 26, 2020, and expects a financing order from the NCUC in May and the securitization transaction to close in Q3 2021.

·	Inclusion of plant in service and other revenue requirement updates through May 31, 2020

Approves the Coal Ash Settlement without modification:

The term of the Coal Ash Settlement goes through early 2030 and resolves all coal ash issues in: (1) the remand of the 2017 rate case; and (2) the 2019 rate case. It also provides much greater certainty on the recovery of coal ash costs incurred through Feb. 2030.

Limits the scope of future rate case proceedings in NC: for the term of the Coal Ash Settlement, the Parties waive all rights to (1) Assert that coal ash costs be shared between DEP and customers through “equitable sharing” or any other rate base or return adjustment, and (2) Challenge the reasonableness and prudence of DEP’s historical coal ash management practices and costs prior to Mar. 2020.

DEP agrees to not seek recovery of approximately $600 million of system-wide deferred coal ash expenditures, including $261 million related to the 2019 Rate Case. As a result of the Coal Ash Settlement, DEP incurred a pre-tax charge of approximately $600 million in Q4 2020, which was treated as a “special item” and excluded from adjusted earnings per share.

Affirms prudency and cost recovery of coal ash costs in the 2017 rate case, including 5-year amortization with a full WACC return and the previously assessed cost of service penalty.

Allows a return at a reduced ROE during the amortization period on coal ash costs in the 2019 Rate Case and through Feb. 2030. The reduced ROE will be 150 basis points lower than the prevailing ROE over the settlement period (e.g. coal ash costs in the 2019 Rate Case will earn a reduced ROE of 8.1%), with a capital structure composed of 48% debt and 52% equity.

DEP retains the ability to earn a full WACC return during the deferral period.

The amortization period for coal ash costs in the 2019 Rate Case will be 5 years. The amortization periods for future deferred costs will be set by the NCUC in future rate case proceedings.

Denies accelerated coal plant depreciation:

Denies DEP’s proposal to shorten the remaining depreciable lives of three coal-fired units. Instead, the Commission stated that the ongoing Integrated Resource Plan docket was the more appropriate venue to decide these issues.

Rate reductions as a result of federal and state tax reform as agreed to in the Second Partial Stipulation include:

Protected federal EDIT: $770 million returned to customers through base rates; annual rate reduction is in accordance with specific IRS requirements governing the flowback period (approximately 28 years)

Unprotected federal EDIT: $400 million returned to customers through the combination of interim rates and a levelized rider over a five-year period

N.C. state EDIT related to the reduction of the N.C. state income tax rate from 3% to 2.5%: $24 million returned to customers through a levelized rider over a two-year period

Deferred revenues from January through November 2018 related to the change in the federal statutory tax rate from 35% to 21%: $110 million returned to customers through a levelized rider over a two-year period

DEP reserves the ability to reflect a future increase or decrease in the federal tax rate during the five-year unprotected EDIT flow back period

Additional Information

The estimated rate base for DEP NC retail addressed in the case is approximately $10.7 billion

Once new tariff schedules are approved by the NCUC, a date will be set for new rates to go into effect. DEP expects new rates to go into effect by June 2021.

Reconciliation of Request to Order and Estimated Annual Rate Impacts to Customer Bills

Original request: $586 million base rate increase, less $122 million combined impact of EDIT and other rider give-backs, for a net requested increase of $464 million

Estimate per Order (Years 1-2): $311 million increase, less $131 million combined impact of EDIT other rider give-backs, for an estimated net increase of $180 million. Note that the net increase will be higher in Years 3-5 as certain federal and state tax reform rate reductions sunset.
