Accounting Policies [Abstract]
Basis of Accounting, Policy [Policy Text Block]	Resources is an energy services company primarily engaged in the sale and distribution of natural gas. The condensed consolidated financial statements include the accounts of Resources and its wholly owned subsidiaries: Roanoke Gas, Diversified Energy and Midstream. In the opinion of management, the accompanying unaudited condensed consolidated financial statements contain all adjustments (consisting of only normal recurring accruals) necessary to fairly present Resources' financial position as of June 30, 2024, cash flows for the nine months ended June 30, 2024 and 2023, and the results of its operations, comprehensive income, and changes in stockholders' equity for the three and nine months ended June 30, 2024 and 2023. The results of operations for the three and nine months ended June 30, 2024 are not indicative of the results to be expected for the fiscal year ending September 30, 2024 as quarterly earnings are affected by the highly seasonal nature of the business and weather conditions generally result in greater earnings during the winter months. The unaudited condensed consolidated financial statements and related notes are presented under the rules and regulations of the SEC. Pursuant to those rules, certain information and note disclosures normally included in the annual financial statements prepared in accordance with GAAP have been condensed or omitted. Although the Company believes that the disclosures are adequate, the unaudited condensed consolidated financial statements and the related notes should be read in conjunction with the financial statements and notes contained in the Company’s Form 10-K for the year ended September 30, 2023. The September 30, 2023 consolidated balance sheet was included in the Company’s audited financial statements included in Form 10-K. Roanoke Gas' line of credit is renewed annually in March, and there was $7.6 million outstanding under the line of credit at June 30, 2024. In March and May 2024, Midstream refinanced nearly $32 million of long-term debt that was scheduled to mature in fiscal 2024 and fiscal 2025. See Notes 6 and 7 for a discussion of these transactions. In the future, there may be circumstances where such refinancing is not entirely within the Company's control and disclosure under ASU 2014-15 is warranted. The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. The Company’s significant accounting policies are described in Note 1 to the consolidated financial statements contained in the Company's Form 10-K for the year ended September 30, 2023. Certain amounts previously disclosed have been reclassified to conform to current year presentations.
New Accounting Pronouncements, Policy [Policy Text Block]	Recently Issued or Adopted Accounting Standards In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848) - Facilitation of the Effects of Reference Rate Reform on Financial Reporting. In combination with ASU 2021-01 and ASU 2022-06, the ASU provides temporary optional guidance to ease the potential burden in accounting for and recognizing the effects of reference rate change on financial reporting. The new guidance applies specifically to contracts and hedging relationships that reference LIBOR, or any other referenced rate that is expected to be discontinued due to reference rate reform. The new guidance is effective for the Company through December 31, 2024. The Intercontinental Exchange Benchmark Administration, the administrator for LIBOR and other inter-bank offered rates, announced that the LIBOR rates for one-day, one-month, six-month and one-year would cease publication in June 2023 and that no new financial contracts may use LIBOR after December 31, 2021. Subsequent to June 30, 2023, the one-day, one-month, six-month, and one-year LIBOR settings will continue to be published under an unrepresentative synthetic methodology until the end of September 2024 in order to bridge the transition to other reference rates. The Company has transitioned all LIBOR-based variable rate notes to a new reference rate as of June 30, 2024. Each of the revised notes has a corresponding swap that was also transitioned to align with the related notes. See Note 7 and Note 9 for more information. In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280) - Improvements to Reportable Segment Disclosures. The new guidance is designed to provide users of financial statements with enhanced disclosures regarding the information provided to the chief operating decision maker (CODM) and how the CODM uses the information in assessing the performance of each segment. The Company is currently evaluating the new standard and determining the additional disclosure requirements. The new guidance is effective for fiscal years beginning after December 15, 2023 and interim periods within fiscal years beginning after December 31, 2024. In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. The new guidance requires that on an annual basis public business entities disclose specific categories in the rate reconciliation table and provide additional information for reconciling items that meet a quantitative threshold (items equal to or greater than 5 percent of the amount computed by multiplying pretax income or loss by the applicable statutory rate). The required disclosures will provide more granularity regarding the payment of income taxes to federal, state and foreign entities. The Company does not expect certain requirements of this ASU to have a significant impact to its current disclosures as all of its operations are domestic and reside in two states. Changes to the rate reconciliation table will result in additional disclosure. The new guidance is effective for public business entities for annual periods beginning after December 15, 2024. In March 2024, the SEC issued its final rule that requires registrants to provide climate disclosures in their annual reports and registration statements. The new guidance requires that registrants provide information about specified financial statement effects of severe weather events and other natural conditions, certain carbon offsets and renewable energy certificates, and material impacts on financial estimates and assumptions in the footnotes to financial statements. The rule also requires additional disclosures outside of the financial statements including governance and oversight of material climate-related risks, the material impact of climate risks on the company's strategy, business model and outlook, risk management processes for material climate-related risks and material climate targets and goals. The Company is currently evaluating the new rule and determining the impact of the additional disclosure requirements, as well as the data needed and the source of that data to comply with required disclosures. The new rule is currently effective for fiscal years beginning in 2027 for smaller reporting companies. The final rule was scheduled to become effective May 28, 2024; however, the SEC has voluntarily stayed the rule's effective date pending judicial review. Depending on when the legal challenges are resolved, the mandatory compliance date may be retained or delayed. Other accounting standards that have been issued by the FASB, SEC or other standard-setting bodies are not currently applicable to the Company or are not expected to have a material impact on the Company’s financial position, results of operations or cash flows.
