Significant Accounting Policies [Line Items]  
Property, Plant and Equipment, Impairment
GAAP requires that we test long-lived assets for impairment when indicators of impairment exist. If an asset is deemed to be impaired, we are required to write down the asset to its fair value with a charge to current earnings. The net book value of our property, plant, and equipment was $2,571.4 million and $2,221.0 million as of December 31, 2024 and 2023, respectively. We do not believe any of these assets are currently impaired. In making this assessment, we consider such factors as: the overall condition and distribution capacity of the assets; the expected ability to recover additional expenditures in the assets; and the anticipated demand and relative pricing of retail electricity in our service territory.
Debt, Policy [Policy Text Block]
Costs incurred in connection with the issuance of long-term debt are deferred and presented as a direct reduction from the face amount of that debt and amortized over the related financing period using the effective interest method. Debt issuance costs related to a line-of-credit or revolving credit facility are deferred and presented as an asset and amortized over the related financing period. Make-whole payments in connection with early debt retirements are classified as cash flows from financing activities.
Financial Statement Presentation DPL’s Consolidated Financial Statements include the accounts of DPL and its wholly-owned subsidiaries, except for DPL Capital Trust II, which is not consolidated consistent with the provisions of GAAP. All material intercompany accounts and transactions are eliminated in consolidation. We have evaluated subsequent events through the date this report was issued.
Reclassifications Certain amounts from prior periods have been reclassified to conform to the current period presentation.
Use of Estimates
The preparation of consolidated financial statements in conformity with GAAP requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities and the revenue and expenses of the periods reported. Actual results could differ from these estimates and assumptions. Significant items subject to such estimates and assumptions include: the carrying value of Property, plant and equipment; unbilled revenue; the valuation of allowances for receivables and deferred income taxes; regulatory assets and liabilities; reserves recorded for income tax exposures; litigation; contingencies; and assets and liabilities related to employee benefits.
Revenue Recognition
Revenue is recognized from retail and wholesale electricity sales and electricity transmission and distribution delivery services. Revenue is recognized upon transfer of control of promised goods or services to customers in an amount that reflects the consideration to which we expect to be entitled in exchange for those goods or services. Energy sales to customers are based on the reading of their meters that occurs on a systematic basis throughout the month. We recognize the revenue on our Consolidated Statements of Operations using an accrual method for retail and other energy sales that have not yet been billed, but where electricity has been consumed. This is termed “unbilled revenue” and is a widely recognized and accepted practice for utilities. At the end of each month, unbilled revenue is determined by the estimation of unbilled energy provided to customers since the date of the last meter reading, estimated line losses, the assignment of unbilled energy provided to customer classes and the average rate per customer class. For more information, see Note 13. Revenue.
Property, Plant and Equipment
New property, plant and equipment additions are stated at cost. For regulated transmission and distribution property, cost includes direct labor and material, allocable overhead expenses and AFUDC. AFUDC represents the cost of borrowed funds and equity used to finance regulated construction projects. Capitalization of AFUDC and interest ceases at either project completion or at the date specified by regulators.
For substantially all depreciable property, when a unit of property is retired, the original cost of that property, less any salvage value, is charged to Accumulated depreciation and amortization, consistent with composite depreciation practices.
Repairs and Maintenance
Costs associated with maintenance activities are recognized at the time the work is performed. These costs, which include labor, materials and supplies and outside services required to maintain equipment and facilities, are capitalized or expensed based on defined units of property.
Regulatory Accounting
As a regulated utility, AES Ohio applies the provisions of ASC 980 - Regulated Operations, which gives recognition to the ratemaking and accounting practices of the PUCO and the FERC. Regulatory assets generally represent incurred costs that have been deferred because such costs are probable of future recovery in customer rates. Regulatory assets can also represent performance incentives permitted by the regulator. Regulatory assets have been included as allowable costs for ratemaking purposes, as authorized by the PUCO or established regulatory practices. Regulatory liabilities generally represent obligations to make refunds or future rate reductions to customers for previous over collections or the deferral of revenue collected for costs that AES Ohio expects to incur in the future.

The deferral of costs (as regulatory assets) is appropriate only when the future recovery of such costs is probable. In assessing probability, we consider such factors as specific orders from the PUCO or the FERC, regulatory precedent and the current regulatory environment. To the extent recovery of costs is no longer deemed probable, related regulatory assets would be required to be expensed in current period earnings. Our regulatory assets and liabilities have been created pursuant to a specific order of the PUCO or the FERC or established regulatory practices, such as other utilities under the jurisdiction of the PUCO or the FERC being granted recovery of similar costs. It is probable, but not certain, that these regulatory assets will be recoverable, subject to approval by the PUCO or the FERC. Regulatory assets and liabilities are classified as current or non-current based on the term in which recovery is expected. See Note 2. Regulatory Matters for more information.
Inventories
Inventories are carried at average cost, net of reserves, and consist of materials and supplies used for utility operations.
Intangibles
Intangibles include software and renewable energy credits. Renewable energy credits are carried on a weighted average cost basis and amortized as they are used or retired. Finite-lived intangible assets include capitalized software amortized on a straight-line basis over their estimated useful lives. These capitalized software intangible assets have a 12.6 year-weighted average amortization period.

The following table presents information related to the Company's capitalized software balances, including the gross amount capitalized and related amortization:

Income Taxes
Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the consolidated financial statement carrying amounts of the existing assets and liabilities and their respective income tax bases. We establish an allowance when it is more likely than not that all or a portion of a deferred tax asset will not be realized. Our tax positions are evaluated under a more likely than not recognition threshold and measurement analysis before they are recognized for consolidated financial statement reporting. Uncertain tax positions have been classified as noncurrent income tax liabilities unless expected to be paid within one year. Our policy for interest and penalties is to recognize interest and penalties as a component of the provision for income taxes in the Consolidated Statements of Operations.

Income taxes payable, which are includable in allowable costs for ratemaking purposes in future years, are recorded as regulatory assets or liabilities with a corresponding deferred tax liability or asset. Investment tax credits that reduced federal income taxes in the years they arose have been deferred and are being amortized to income over the useful lives of the properties in accordance with regulatory treatment. See Note 2. Regulatory Matters for more information.

DPL and its subsidiaries file U.S. federal income tax returns as part of the consolidated U.S. income tax return filed by AES. The consolidated tax liability is allocated to each subsidiary based on the separate return method as specified in our tax allocation agreement, and which provides a consistent, systematic and rational approach. See Note 7. Income Taxes for more information.
Financial Instruments Our Master Trust investments in debt and equity financial instruments of publicly traded entities are classified as equity investments. These equity securities are carried at fair value and unrealized gains and losses on these securities are recorded in Other income. As these financial instruments are held to be used for the benefit of employees or former employees participating in employee benefit plans and are not used for general operating purposes, they are recorded within Other non-current assets on the accompanying Consolidated Balance Sheets. See
Accounting for Taxes Collected from Customers and Remitted to Governmental Authorities
AES Ohio collects certain excise taxes levied by state or local governments from its customers. AES Ohio’s excise taxes and certain other taxes are accounted for on a net basis and recorded as a reduction in revenue in the accompanying Consolidated Statements of Operations. The amounts of such taxes were as follows:
Cash and Cash Equivalents
Cash and Cash Equivalents
Cash and cash equivalents are stated at cost, which approximates fair value. All highly liquid short-term investments with original maturities of three months or less are considered cash equivalents.

Restricted Cash
Restricted cash includes cash which is restricted as to withdrawal or usage. The nature of the restrictions includes restrictions imposed by agreements related to deposits held as collateral.
Financial Derivatives
Financial Derivatives
We have contracts involving the physical delivery of energy. These contracts qualify for the normal purchases and normal sales scope exception in ASC 815 - Derivatives and Hedging, thus we have elected to account for them as accrual contracts, which are not adjusted for changes in fair value.

We have, in the past, used interest rate hedges to manage the interest rate risk of our variable rate debt. We used cash flow hedge accounting when the hedge or a portion of the hedge was deemed to be highly effective, which resulted in changes in fair value being recorded within accumulated other comprehensive loss, a component of shareholder’s equity / (deficit). We elected not to offset net derivative positions in the consolidated financial statements. Accordingly, we did not offset such derivative positions against the fair value of amounts recognized for the right to reclaim cash collateral or the obligation to return cash collateral under master netting agreements. See Note 5. Derivative Instruments and Hedging Activities for more information.
Insurance and Claims Costs
Insurance and Claims Costs
In addition to insurance obtained from third-party providers, MVIC, a wholly-owned captive subsidiary of DPL, provides insurance coverage solely to us and our subsidiaries for workers’ compensation, general liability and property damage on an ongoing basis. Estimates of the liabilities for insurance and claims costs associated with MVIC and the liabilities for medical, life, disability and other reserves for claims costs below certain coverage thresholds of third-party providers are as follows:
Balance SheetDecember 31,
$ in millionsClassification20242023
Estimated insurance and claims costsAccrued and other current liabilities$2.2 $1.8 
Estimated liabilities for medical, life, disability and other reserves
Accrued and other current liabilities and Other non-current liabilities
$7.3 $8.0 

The estimated liabilities for workers’ compensation, medical, life and disability costs at DPL are actuarially determined using certain assumptions. There is uncertainty associated with these loss estimates, and actual results may differ from the estimates. Modification of these loss estimates based on experience and changed circumstances is reflected in the period in which the estimate is re-evaluated.
Pension and Postretirement Benefits
We recognize in our Consolidated Balance Sheets an asset or liability reflecting the funded status of pension and other postretirement plans with current-year changes from actuarial gains or losses related to our regulated operations, which would otherwise be recognized in AOCL, recorded as a regulatory asset as this can be recovered through future rates. Such changes that are not related to our regulated operations are recognized in AOCL. All plan assets are recorded at fair value. We follow the measurement date provisions of the accounting guidance, which require a year-end measurement date of plan assets and obligations for all defined benefit plans.

We account for and disclose pension and postretirement benefits in accordance with the provisions of GAAP relating to the accounting for pension and other postretirement plans. These GAAP provisions require the use of assumptions, such as the discount rate for liabilities and long-term rate of return on assets, in determining the obligations, annual cost and funding requirements of the plans. Consistent with the requirements of ASC 715 - Compensation - Retirement Benefits, we apply a disaggregated discount rate approach for determining service cost and interest cost for our defined benefit pension plans and postretirement plans.

See Note 8. Benefit Plans for more information.
Related Party Transactions
In the normal course of business, DPL enters into transactions with related parties. All material intercompany accounts and transactions are eliminated in DPL’s Consolidated Financial Statements. See Note 11. Related Party Transactions for more information.

ASU Number and NameDescriptionDate of AdoptionEffect on the financial statements upon adoption
2023-06 Disclosure Improvements: Codification Amendments in Response to the SEC’s Disclosure Update and Simplification Initiative
In U.S. Securities and Exchange Commission (SEC) Release No. 33-10532, Disclosure Update and Simplification, issued August 17, 2018, the SEC referred certain of its disclosure requirements that overlap with, but require incremental information to, generally accepted accounting principles (GAAP) to the FASB for potential incorporation into the Codification. The amendments in this Update are the result of the Board’s decision to incorporate into the Codification 14 of the 27 disclosures referred by the SEC.

The amendments in this Update represent changes to clarify or improve disclosure and presentation requirements of a variety of Topics. Many of the amendments allow users to more easily compare entities subject to the SEC’s existing disclosures with those entities that were not previously subject to the SEC’s requirements. Also, the amendments align the requirements in the Codification with the SEC’s regulations.
The effective date for each amendment will be the date on which the SEC's removal of that related disclosure becomes effective, with early adoption prohibited. The amendments in this Update should be applied prospectivelyWe will provide the required disclosures on a prospective basis on the date each amendment becomes effective. We do not expect ASU 2023-06 will have any impact on our Consolidated Financial Statements.
2023-09 Income Taxes (Topic 740): Improvements to Income Tax DisclosuresThe amendments in this Update require that public business entities on an annual basis (1) disclose specific categories in the rate reconciliation and (2) provide additional information for reconciling items that meet a quantitative threshold. Furthermore, companies are required to disclose a disaggregated amount of income taxes paid at a federal, state, and foreign level as well as a break down of income taxes paid in a jurisdiction that comprises 5% of a company's total income taxes paid. Lastly, this ASU requires that companies disclose income (loss) from continuing operations before income tax at a domestic and foreign level and that companies disclose income tax expense from continuing operations on a federal, state, and foreign level.The amendments in this Update are effective for fiscal years beginning after December 15, 2024We are currently evaluating the impact of adopting the standard on our Consolidated Financial Statements.
2024-03: Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40)The amendments in this Update require disclosure, in the notes to financial statements, of specified information about certain costs and expenses. The amendments require that at each interim and annual reporting period an entity:

1. Disclose the amounts of (a) purchases of inventory, (b) employee compensation, (c) depreciation, (d) intangible asset amortization, and (e) depreciation, depletion, and amortization recognized as part of oil- and gas-producing activities (DD&A) (or other amounts of depletion expense) included in each relevant expense caption. A relevant expense caption is an expense caption presented on the face of the income statement within continuing operations that contains any of the expense categories listed in (a)–(e).

2. Include certain amounts that are already required to be disclosed under current generally accepted accounting principles (GAAP) in the same disclosure as the other disaggregation requirements.

3. Disclose a qualitative description of the amounts remaining in relevant expense captions that are not separately disaggregated quantitatively.

4. Disclose the total amount of selling expenses and, in annual reporting periods, an entity’s definition of selling expenses.
The date for each amendment in this Update is effective for fiscal years beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027. Early adoption is permittedWe are currently evaluating the impact of adopting the standard on our Consolidated Financial Statements.
Commitments and Contingencies, Policy
DPL accrues for loss contingencies when the amount of the loss is probable and estimable. We are subject to various environmental regulations and are involved in certain legal proceedings. If DPL’s actual environmental and/or legal obligations are different from our estimates, the recognition of the actual amounts may have a material impact on our results of operations, financial condition and cash flows; although that has not been the case during the periods covered by this report. Accruals for loss contingencies were not material as of December 31, 2024 and 2023. See Note 10. Contractual Obligations, Commercial Commitments and Contingencies for additional information.
Lessee, Leases
We have operating leases primarily for office space in which we are the lessee. Operating leases with an initial term of 12 months or less are not recorded on the balance sheet, but are expensed on a straight-line basis over the lease term. Our leases do not contain any material residual value guarantees, restrictive covenants or subleases.

Right-of-use assets represent our right to use an underlying asset for the lease term while lease liabilities represent our obligation to make lease payments arising from the lease. Right-of-use assets and lease liabilities are recognized on commencement of the lease based on the present value of lease payments over the lease term. Generally, the rate implicit in the lease is not readily determinable; as such, we use the incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. We determine discount rates based on the existing credit rates of our borrowings which are then adjusted for the appropriate lease term. The right-of-use asset also includes any lease payments made and excludes lease
incentives that are paid or payable to the lessee at commencement. The lease term includes periods covered by the option to extend if it is reasonably certain that the option will be exercised and periods covered by an option to terminate if it is reasonably certain that the option will not be exercised.

Property, Plant and Equipment, Impairment
GAAP requires that we test long-lived assets for impairment when indicators of impairment exist. If an asset is deemed to be impaired, we are required to write down the asset to its fair value with a charge to current earnings. The net book value of our property, plant, and equipment was $2,546.2 million and $2,195.9 million as of December 31, 2024 and 2023, respectively. We do not believe any of these assets are currently impaired. In making this assessment, we consider such factors as: the overall condition and distribution capacity of the assets; the expected ability to recover additional expenditures in the assets; and the anticipated demand and relative pricing of retail electricity in our service territory.
Debt, Policy [Policy Text Block]
Costs incurred in connection with the issuance of long-term debt are deferred and presented as a direct reduction from the face amount of that debt and amortized over the related financing period using the effective interest
method. Debt issuance costs related to a line-of-credit or revolving credit facility are deferred and presented as an asset and amortized over the related financing period. Make-whole payments in connection with early debt retirements are classified as cash flows from financing activities.
Financial Statement Presentation

Use of Estimates
The preparation of financial statements in conformity with GAAP requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities and the revenue and expenses of the periods reported. Actual results could differ from these estimates and assumptions. Significant items subject to such estimates and assumptions include: the carrying value of Property, plant and equipment; unbilled revenue; the valuation of allowances for receivables and deferred income taxes; regulatory assets and liabilities; reserves recorded for income tax exposures; litigation; contingencies; and assets and liabilities related to employee benefits.
Property, Plant and Equipment
New property, plant and equipment additions are stated at cost. For regulated transmission and distribution property, cost includes direct labor and material, allocable overhead expenses and AFUDC. AFUDC represents the cost of borrowed funds and equity used to finance regulated construction projects. Capitalization of AFUDC and interest ceases at either project completion or at the date specified by regulators.

For substantially all depreciable property, when a unit of property is retired, the original cost of that property, less any salvage value, is charged to Accumulated depreciation and amortization, consistent with composite depreciation practices. Depreciation expense is calculated using the straight-line method, which allocates the cost of property over its estimated useful life. For AES Ohio’s transmission and distribution assets, straight-line depreciation is applied monthly on an average composite basis using group rates. Depreciation and amortization expense in the Statements of Operations is presented net of regulatory deferrals of depreciation expense and also includes amortization of intangible assets and amortization of previously deferred regulatory costs. The following table presents average composite group rates and depreciation expense for each respective period.

AES Ohio may receive contributions in aid of construction ("CIAC") from customers that are intended to defray all or a portion of the costs for certain capital projects, to the extent the project does not benefit regulated customers in general. AES Ohio accounts for CIAC as a reduction to property, plant and equipment.
AFUDC
In accordance with the Uniform System of Accounts prescribed by FERC, AES Ohio capitalizes an allowance for the net cost of funds (interest on borrowed funds and a reasonable rate of return on equity funds) used for construction purposes during the period of construction with a corresponding credit to income. AFUDC equity and AFUDC debt were as follows for the years ended December 31, 2024, 2023 and 2022:

Regulatory assets and liabilities are classified as current or non-current based on the term in which recovery is expected. See Note 2. Regulatory Matters for more information.
Inventories nventories are carried at average cost, net of reserves, and include materials and supplies used for utility operations.
Intangibles
Intangibles include software and renewable energy credits. Renewable energy credits are carried on a weighted average cost basis and amortized as they are used or retired. Finite-lived intangible assets include capitalized software amortized on a straight-line basis over their estimated useful lives. These capitalized software intangible assets have a 12.6 year-weighted average amortization period.

Income Taxes
Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of the existing assets and liabilities and their respective income tax bases. We establish an allowance when it is more likely than not that all or a portion of a deferred tax asset will not be realized. Our tax positions are evaluated under a more likely than not recognition threshold and measurement analysis before they are recognized for financial statement reporting. Uncertain tax positions have been classified as noncurrent income tax liabilities unless expected to be paid within one year. Our policy for interest and penalties is to recognize interest and penalties as a component of the provision for income taxes in the Statements of Operations.

Income taxes payable, which are includable in allowable costs for ratemaking purposes in future years, are recorded as regulatory assets or liabilities with a corresponding deferred tax liability or asset. Investment tax credits that reduced federal income taxes in the years they arose have been deferred and are being amortized to income over the useful lives of the properties in accordance with regulatory treatment. See Note 2. Regulatory Matters for more information.

AES Ohio files U.S. federal income tax returns as part of the consolidated U.S. income tax return filed by AES. The consolidated tax liability is allocated to each subsidiary based on the separate return method as specified in our tax allocation agreement, and which provides a consistent, systematic and rational approach. See Note 6. Income Taxes for more information.

Commitments and Contingencies, Policy AES Ohio accrues for loss contingencies when the amount of the loss is probable and estimable. We are subject to various environmental regulations and are involved in certain legal proceedings. If AES Ohio’s actual environmental and/or legal obligations are different from our estimates, the recognition of the actual amounts may have a material impact on our results of operations, financial condition and cash flows; although that has not been the case during the periods covered by this report. Accruals for loss contingencies were not material as of December 31, 2024 and 2023. See Note 9. Contractual Obligations, Commercial Commitments and Contingencies for additional information
Credit Loss, Financial Instrument
The allowance for credit losses primarily relates to utility customer receivables, including unbilled amounts. Expected credit loss estimates are developed by disaggregating customers into those with similar credit risk characteristics and using historical credit loss experience. In addition, we also consider how current and future economic conditions are expected to impact collectability, as applicable, of our receivables balance. Amounts are written off when reasonable collections efforts have been exhausted. During 2024, the current period provision and allowance for credit losses increased due to a temporary pause of customer disconnections and certain collection efforts and write-off processes after the implementation of our customer billing system upgrade in the third quarter of 2024. We currently anticipate reinstituting the customer disconnections process and collection efforts and write-off processes by the end of the third quarter of 2025.
