Organization, Consolidation and Presentation of Financial Statements [Abstract] | |
Basis of Presentation | Basis of Presentation Boardwalk Pipeline Partners, LP (the Company) is a Delaware limited partnership formed in 2005 to own and operate the business conducted by its primary subsidiary Boardwalk Pipelines, LP (Boardwalk Pipelines) and its operating subsidiaries, which consists of integrated pipeline and storage systems for natural gas and natural gas liquids and other hydrocarbons (herein referred to together as NGLs). As of September 30, 2024, Boardwalk Pipelines Holding Corp. (BPHC), a wholly owned subsidiary of Loews Corporation (Loews), owned directly or indirectly, 100% of the Company's capital. The accompanying unaudited condensed consolidated financial statements of the Company have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission. Certain information and footnote disclosures normally included in annual financial statements prepared in accordance with accounting principles generally accepted in the United States of America (U.S.) (GAAP) have been condensed or omitted pursuant to such rules and regulations. In the opinion of management, the accompanying unaudited condensed consolidated financial statements reflect all adjustments (consisting of only normal recurring accruals) necessary to present fairly the Company's financial position as of September 30, 2024, and December 31, 2023, its results of operations, comprehensive income and changes in partners' capital for the three and nine months ended September 30, 2024 and 2023, and its changes in cash flows for the nine months ended September 30, 2024 and 2023, in each case in accordance with GAAP. Reference is made to the Notes to the Consolidated Financial Statements in the Company's Annual Report on Form 10-K for the year ended December 31, 2023 (2023 Annual Report on Form 10-K), which should be read in conjunction with these unaudited condensed consolidated financial statements. The accounting policies described in Note 2 of Part II, Item 8. of the Company's 2023 Annual Report on Form 10-K are the same policies that were used in preparing the accompanying unaudited condensed consolidated financial statements. Results of operations for interim periods may not necessarily be indicative of results for the full year. Certain amounts reported in Other revenues were reclassified to Product sales to conform to the current presentation in connection with the acquisition discussed in Note 2. The amounts reclassified represent NGL product sales that occurred during 2023. Costs associated with these product sales were immaterial. The effect of the reclassification was a decrease in Other revenues and an increase in Product sales of $0.8 million for 2023. This reclassification had no impact on Total operating revenues, Operating income or Net income. Short-Term Investment Accounting Policy The Company has invested in short-term investments that have been classified as held-to-maturity as the Company has the intent and the ability to hold the short-term investments until they mature. As of September 30, 2024, the Company had recorded $603.1 million of U.S. treasury bills on its Condensed Consolidated Balance Sheets, maturing in December 2024, at amortized cost. The carrying amount of the U.S. treasury bills was adjusted for the accretion of discounts over the remaining life of the investment. Income related to the U.S. treasury bills was recorded in Interest Income on the Condensed Consolidated Statements of Income. As of September 30, 2024, the U.S. treasury bills had unrecognized gains of $0.6 million.

Revenues | Revenues The Company operates in one reportable segment. It contracts directly with end-use customers, including electric power generators, local distribution companies, industrial users and exporters of liquefied natural gas. The Company also contracts with other customers, including producers and marketers of natural gas and interstate and intrastate pipelines, who, in turn, provide transportation and storage services for end-users. The following table presents the Company's revenues disaggregated by type of service (in millions):
(1)Revenues earned from contracts with minimum volume commitments (MVCs) are included in firm service given the stand-ready nature of the performance obligation and the guaranteed nature of the fees over the contract term. (2)For the three and nine months ended September 30, 2024, revenues attributable to Bayou Ethane were $53.9 million and $150.0 million included in firm service from product sales earned from contracts with MVCs; $20.6 million and $91.4 million included in other revenues from product sales earned from contracts with no MVCs; and $1.5 million and $3.8 million included in other operating revenues. (3)Other operating revenues include certain revenues earned from operating leases, pipeline management fees and other activities that are not considered central and ongoing major business operations of the Company and do not represent revenues earned from contracts with customers. Contract Balances As of September 30, 2024, and December 31, 2023, the Company had receivables recorded in Trade Receivables, net from contracts with customers of $161.2 million and $204.6 million, contract assets recorded in Other Assets from contracts with a customer of $10.8 million and $6.2 million, and contract liabilities recorded in Other Current Liabilities (current portion) and Other Liabilities (noncurrent portion) from contracts with customers of $19.8 million and $21.4 million. As of September 30, 2024, contract liabilities are expected to be recognized through 2040. Significant changes in the contract liability balances during the nine months ended September 30, 2024, were as follows (in millions):
(1)As of September 30, 2024, and December 31, 2023, $3.3 million and $3.5 million were recorded in Other Current Liabilities (current portion), and $16.5 million and $17.9 million were recorded in Other Liabilities (noncurrent portion). Significant changes in the contract liability balances during the nine months ended September 30, 2023, were as follows (in millions):
(1)As of September 30, 2023, and December 31, 2022, $3.7 million and $3.6 million were recorded in Other Current Liabilities (current portion), and $18.5 million and $19.4 million were recorded in Other Liabilities (noncurrent portion). Performance Obligations The following table includes estimated operating revenues expected to be recognized in the future related to agreements that contain performance obligations that were unsatisfied as of September 30, 2024. The amounts presented primarily consist of fixed fees or MVCs which are typically recognized over time as the performance obligation is satisfied, in accordance with firm service contracts, or at a point in time as guaranteed minimum fees associated with the performance obligation are satisfied under certain ethane supply contracts. For the Company's customers that are charged maximum tariff rates related to its Federal Energy Regulatory Commission (FERC) regulated operating subsidiaries, the amounts below reflect the current tariff rate for such services for the term of the agreements; however, the tariff rates may be subject to future adjustment. The Company has elected to exclude the following from the table: (a) unsatisfied performance obligations from usage fees associated with its firm services because of the variable nature of such services; (b) unsatisfied performance obligations from the ethane commodity indexed portion of ethane supply contracts because of the variable nature of ethane prices, and (c) consideration in contracts that is recognized in revenue as invoiced, such as for interruptible services. The estimated revenues reflected in the table may include estimated revenues that are anticipated under executed precedent transportation agreements for projects that are subject to regulatory approvals.
(1)The 2024 period is for the remaining three months ending December 31, 2024. For the nine months ended September 30, 2024, the Company recognized $1,084.5 million of fixed fee revenues for the fulfillment of performance obligations. (2)In March 2024, the Company executed a 108-year firm storage agreement with a customer. The estimated annual revenue from this contract is $3.1 million, with $331.6 million of unsatisfied performance obligations included in the “Thereafter” column. Per the tariff provisions, this customer was required to provide 90 days of collateral and the Company can suspend services due to non-payment.

Oil and Gas, Gas-Balancing Arrangement [Abstract] | |
Gas and liquids stored underground and gas and NGLs receivables and payables | Gas and Liquids Stored Underground and Gas and NGLs Receivables and Payables The operating subsidiaries of the Company provide storage services whereby they store natural gas or NGLs on behalf of customers and also periodically hold customer gas under parking and lending (PAL) services. Since the customers retain title to the gas or NGLs held by the Company in providing these services, the Company does not record the related gas or NGLs on its Condensed Consolidated Balance Sheets. The operating subsidiaries of the Company also periodically lend gas to customers under PAL and certain firm services, and lend ethylene to customers under exchange agreements, and gas or NGLs may be owed to the Company's operating subsidiaries as a result of transportation imbalances. As of September 30, 2024, the amount of gas owed to the Company's operating subsidiaries due to gas imbalances and gas loaned under PAL and certain firm service agreements was approximately 6.7 trillion British thermal units (TBtu). Assuming an average market price during September 2024 of $2.17 per million British thermal unit (MMBtu), the market value of that gas was approximately $14.5 million. As of September 30, 2024, the amount of ethylene owed to the Company’s operating subsidiaries from ethylene loaned under exchange agreements was approximately 34.0 million pounds. Assuming an average market price during September 2024 of $0.21 per pound, the market value of that ethylene was approximately $7.1 million. As of December 31, 2023, the amount of gas owed to the Company's operating subsidiaries due to gas imbalances and gas loaned under PAL and certain firm service agreements was approximately 11.2 TBtu. Assuming an average market price during December 2023 of $2.33 per MMBtu, the market value of that gas was approximately $26.1 million. There were no amounts of ethylene owed to the Company's operating subsidiaries under exchange agreements as of December 31, 2023. As of September 30, 2024, and December 31, 2023, there were no outstanding NGL imbalances owed to the Company's operating subsidiaries.

Commitments and Contingencies Disclosure [Abstract] | |
Commitments and Contingencies | Commitments and Contingencies Legal Proceedings and Settlements The Company and its subsidiaries are parties to various legal actions arising in the normal course of business. Management believes the disposition of these outstanding legal actions, including the legal actions identified below, will not have a material impact on the Company's financial condition, results of operations or cash flows. Mishal and Berger Litigation On May 25, 2018, plaintiffs Tsemach Mishal and Paul Berger (on behalf of themselves and the purported class, Plaintiffs) initiated a purported class action in the Court of Chancery of the State of Delaware (the Trial Court) against the following defendants: the Company, Boardwalk GP, LP (Boardwalk GP), Boardwalk GP, LLC and BPHC (together, Defendants), regarding the potential exercise by Boardwalk GP of its right to purchase the issued and outstanding common units of the Company not already owned by Boardwalk GP or its affiliates (Purchase Right). On June 25, 2018, Plaintiffs and Defendants entered into a Stipulation and Agreement of Compromise and Settlement, subject to the approval of the Trial Court (the Proposed Settlement). Under the terms of the Proposed Settlement, the lawsuit would be dismissed, and related claims against the Defendants would be released by the Plaintiffs, if BPHC, the sole member of the general partner of Boardwalk GP, elected to cause Boardwalk GP to exercise its Purchase Right for a cash purchase price, as determined by the Company's Third Amended and Restated Agreement of Limited Partnership, as amended (the Limited Partnership Agreement), and gave notice of such election as provided in the Limited Partnership Agreement within a period specified by the Proposed Settlement. On June 29, 2018, Boardwalk GP elected to exercise the Purchase Right and gave notice within the period specified by the Proposed Settlement. On July 18, 2018, Boardwalk GP completed the purchase of the Company's common units pursuant to the Purchase Right. On September 28, 2018, the Trial Court denied approval of the Proposed Settlement. On February 11, 2019, a substitute verified class action complaint was filed in this proceeding, which, among other things, added Loews as a Defendant. The Defendants filed a motion to dismiss, which was heard by the Trial Court in July 2019. In October 2019, the Trial Court ruled on the motion and granted a partial dismissal, with certain aspects of the case proceeding to trial. A trial was held the week of February 22, 2021, and post-trial oral arguments were held on July 14, 2021. On November 12, 2021, the Trial Court issued a ruling in the case. The Trial Court held that Boardwalk GP breached the Limited Partnership Agreement and found that Boardwalk GP was liable to the Plaintiffs for approximately $690.0 million in damages, plus pre-judgment interest (approximately $166.0 million), post-judgment interest and attorneys' fees. The Trial Court's ruling and damages award was against Boardwalk GP, and not the Company or its subsidiaries. The Defendants believed that the Trial Court ruling included factual and legal errors. Therefore, on January 3, 2022, the Defendants appealed the Trial Court's ruling to the Supreme Court of the State of Delaware (the Supreme Court). On January 17, 2022, the Plaintiffs filed a cross-appeal to the Supreme Court contesting the calculation of damages by the Trial Court. Oral arguments were held on September 14, 2022, and on December 19, 2022, the Supreme Court reversed the Trial Court's ruling and remanded the case to the Trial Court for further proceedings related to claims not decided by the Trial Court's ruling. Briefing by the parties at the Trial Court on the remanded issues was completed in September 2023. A hearing on the remanded issues was held at the Trial Court in April 2024. In September 2024, the Trial Court ruled in favor of the Defendants on all of the remanded issues. On October 21, 2024, the Plaintiffs appealed the Trial Court's ruling on the remanded issues to the Supreme Court. City of New Orleans Litigation Gulf South Pipeline Company, LLC (Gulf South), along with several other energy companies operating in Southern Louisiana, has been named as a defendant in a petition for damages and injunctive relief in state district court for Orleans Parish, Louisiana, (Case No. 19-3466) by the City of New Orleans. The case was filed on March 29, 2019. The lawsuit claims include, among other things, negligence, strict liability, nuisance and breach of contract, alleging that the defendants' drilling, dredging, pipeline and industrial operations since the 1930s have caused increased storm surge risk, increased flood protection costs and unspecified damages to the City of New Orleans. In October 2020, this case was stayed pending the outcome of a consolidated appeal to the Fifth Circuit Court of Appeals in a similar case. On August 5, 2021, the Fifth Circuit Court of Appeals ruled in favor of the oil-and-gas defendants in that consolidated appeal, finding that the two cases being appealed should be re-examined in federal district court since they involve operations that were federally overseen at the time. The ruling reverses a previous decision that allowed the cases to be heard in state court, which the plaintiffs had sought. As a result of the Fifth Circuit Court of Appeals' decision, it is anticipated that this case will be reviewed in federal district court to determine whether the case should be heard in that court. Discovery has been initiated. Gulf South and Texas Gas Transmission, LLC (Texas Gas) have been named as defendants in several suits in the State of Louisiana that are similar in nature to the City of New Orleans Litigation discussed above. These cases were filed in Louisiana state courts and discovery is ongoing. One of these cases was settled in the second quarter 2024 and it did not have a material impact to the Company's results of operations or equity. Regulatory Cost Recovery Mechanism On May 1, 2024, Gulf South filed with the FERC a regulatory cost recovery mechanism, to be included in Gulf South's tariff, that would allow Gulf South to track and recover, via a surcharge, the costs of complying with certain new environmental regulatory requirements and regulatory requirements imposed by the Pipeline and Hazardous Materials Safety Administration. Gulf South requested that the regulatory cost recovery mechanism have an initial term of five years beginning on November 1, 2024. On October 31, 2024, Gulf South received an order from the FERC rejecting the cost recovery mechanism. Commitments for Construction The Company's future capital commitments are comprised of binding commitments under purchase orders for materials ordered but not received and firm commitments under binding construction service agreements. As of September 30, 2024, the commitments were approximately $141.3 million, all of which are expected to be settled within the next twelve months.
