TABLE OF CONTENTS
I. INTRODUCTION AND QUALIFICATIONS
A. Witness Identification
Q. Please state your full name, title, and business address.
A. My name is Angela Moretti. I am Vice President, Finance & Treasurer of Ridgeline Midstream Services LLC ("Ridgeline" or "RMS"). My principal office is located at 700 Kanawha Boulevard East, Suite 1400, Charleston, West Virginia 25301. I am testifying in this proceeding on behalf of Ridgeline Midstream Services LLC, the applicant in the above-captioned dockets.
Q. On whose behalf are you testifying?
A. I am testifying on behalf of Ridgeline Midstream Services LLC, the applicant in Docket Nos. RP22-847-000 and RP22-847-001. Ridgeline is an interstate natural gas pipeline company subject to the jurisdiction of the Federal Energy Regulatory Commission ("FERC" or the "Commission") under the Natural Gas Act ("NGA"), 15 U.S.C. §§ 717 et seq.
B. Professional Background and Qualifications
Q. Please describe your educational background.
A. I hold a Bachelor of Science degree in Accounting from the University of Virginia, which I received in 2001. I also hold a Master of Business Administration degree with a concentration in Corporate Finance from the Wharton School of the University of Pennsylvania, which I received in 2005. I am a Certified Public Accountant licensed in the Commonwealth of Virginia and the State of West Virginia. I have maintained my CPA certifications through continuing professional education throughout my career.
Q. Please describe your professional experience.
A. I have over twenty years of experience in energy industry finance, regulatory accounting, and financial management. My career has been devoted almost exclusively to the midstream natural gas and oil pipeline sector, with extensive experience in FERC-jurisdictional cost-of-service filings, rate proceedings, and regulatory financial reporting.
From 2001 to 2005, prior to attending business school, I served as a Staff Accountant and subsequently Senior Accountant at Penrose Group in Clarksburg, West Virginia, where I was responsible for the preparation of FERC Form No. 2 annual reports, regulatory accounting entries, and supporting workpapers for rate case filings before this Commission.
Following the completion of my MBA in 2005, I joined Larkspur Holdings (now Hollowell Corporation) in Charleston, West Virginia, where I served in progressively responsible positions within the finance and regulatory accounting departments. From 2005 to 2008, I served as Manager, Regulatory Accounting. From 2008 to 2012, I served as Director, Financial Planning & Analysis. During my tenure at Harborline Group, I was directly involved in two general rate case filings before FERC, including the preparation of cost-of-service studies, rate base calculations, capital structure presentations, and supporting testimony workpapers.
From 2012 to 2017, I served as Vice President, Finance at Mountaineer Pipeline Company, LLC, a privately held interstate natural gas pipeline company operating in the Appalachian Basin. At Mountaineer Pipeline, I was responsible for all aspects of financial operations, including treasury management, capital budgeting, debt issuance and management, tax planning, and regulatory financial reporting. I was the lead financial witness in Mountaineer Pipeline's 2015 rate case filing before this Commission in Docket No. RP15-312-000, where I presented testimony on cost of service, rate base, capital structure, and cost of capital.
In 2017, I joined Ridgeline Midstream Services LLC in my current position as Vice President, Finance & Treasurer. In this role, I have overall responsibility for all of Ridgeline's financial operations, including treasury, accounting, tax, financial planning and analysis, and regulatory financial reporting. I report directly to James K. Winfield, Chief Executive Officer and President of Ridgeline Midstream Services LLC.
Q. What are your current responsibilities at Ridgeline?
A. As Vice President, Finance & Treasurer, I am responsible for the oversight and management of all financial operations of Ridgeline Midstream Services LLC. My responsibilities include, but are not limited to:
• Oversight of the corporate treasury function, including cash management, banking relationships, and liquidity planning;
• Management of all debt financing activities, including the Senior Secured Credit Facility and the Second Lien Senior Secured Notes;
• Oversight of the accounting function, including the maintenance of books and records in accordance with the FERC Uniform System of Accounts prescribed in 18 C.F.R. Part 201;
• Preparation and filing of FERC Form No. 2 annual reports;
• Tax planning and compliance, including coordination with outside tax advisors;
• Financial planning, budgeting, and forecasting;
• Regulatory financial reporting and support for rate proceedings before FERC; and
• Coordination with our parent company, Dunmore Energy Holdings Ltd. ("DEH"), on financial matters, capital allocation, and intercompany transactions.
I supervise a team of twelve professionals in the finance, accounting, and treasury departments at Ridgeline. I also serve as the primary liaison with Ridgeline's outside auditors at Ashford & McBride LLP, and with our banking syndicate led by Pinnacle National Bank, N.A.
Q. Have you previously testified before the Federal Energy Regulatory Commission or any other regulatory body?
A. Yes. As noted above, I served as the lead financial witness in the general rate case filing of Mountaineer Pipeline Company, LLC, before this Commission in Docket No. RP15-312-000. In that proceeding, I presented pre-filed direct testimony and rebuttal testimony on cost of service, rate base, capital structure, and cost of capital. I was cross-examined at the evidentiary hearing and my testimony was accepted into the record. The Commission's order in that proceeding approved a cost of service and rate base substantially consistent with the amounts I presented. I have also presented testimony before the Public Service Commission of West Virginia on two occasions in connection with intrastate pipeline rate matters.
C. Purpose of Testimony
Q. What is the purpose of your testimony in this proceeding?
A. The purpose of my testimony is to present and support the cost-of-service and rate base components of Ridgeline's initial rate filing in this proceeding. Specifically, my testimony addresses the following:
1. The test-year cost of service of $97.36 million that forms the basis for Ridgeline's proposed recourse rates;
2. The rate base of $612.40 million as of the test year ended March 31, 2022;
3. The proposed capital structure of 55% equity and 45% debt;
4. The weighted average cost of debt of 5.25%;
5. The proposed return on rate base, computed using a weighted average cost of capital of 10.0625%;
6. The annual depreciation expense of $14.68 million;
7. The operating expenses of $17.26 million, consisting of operations and maintenance ("O&M") expense and administrative and general ("A&G") expense;
8. Taxes, including taxes other than income taxes and the income tax allowance;
9. Revenue credits of $16.10 million; and
10. The identification of supporting exhibits and workpapers (Exhibits A through P filed with the application) that document and support the figures presented in my testimony.
I note that the return on equity ("ROE") of 14.00% that is incorporated into my cost-of-service calculation is addressed separately and in detail in the pre-filed direct testimony of Dr. Raymond Braswell, Ridgeline's expert witness on cost of equity. Dr. Braswell presents a discounted cash flow ("DCF") proxy group analysis supporting the proposed 14.00% ROE. My testimony takes the 14.00% ROE as given and incorporates it into the overall cost-of-service calculation.
Additionally, the detailed rate design methodology, including the reservation/usage rate split, is addressed in the pre-filed direct testimony of Dr. Natasha Orlov. My testimony presents the total cost of service and provides summary rate calculations for informational purposes, but the rate design details are properly within the scope of Dr. Orlov's testimony.
D. Summary of Conclusions
Q. Please summarize the principal conclusions of your testimony.
A. My testimony supports the following principal conclusions:
1. Ridgeline's total rate base, as filed, is $612.40 million. This figure is derived from Ridgeline's books and records, is computed in accordance with the FERC Uniform System of Accounts, and reflects the historical cost of the Ridgeline Pipeline System less accumulated depreciation, adjusted for accumulated deferred income taxes ("ADIT") and other rate base items including working capital allowance.
2. The proposed weighted average cost of capital ("WACC") is 10.0625%, computed using a capital structure of 55% equity and 45% debt, a return on equity of 14.00%, and a weighted average cost of debt of 5.25%.
3. The total cost of service is $97.36 million. This amount includes the return on rate base, depreciation expense, operating expenses, taxes, income tax allowance, and is net of revenue credits.
4. These figures are just and reasonable within the meaning of Sections 4 and 5 of the Natural Gas Act and are supported by Ridgeline's audited books and records, FERC Form No. 2 data, and the detailed workpapers filed as Exhibits A through P to the application.

The founder, Chairperson, and controlling shareholder of DEH is Patricia Dunmore, who holds a 72% equity interest in DEH. The remaining 28% equity interest is held by a group of institutional investors and family trusts. Ms. Dunmore serves as Chairperson of the Board of Directors of DEH and has served in that capacity since the company's founding in 2009.
B. The Ridgeline Pipeline System
Q. Please describe the Ridgeline Pipeline System.
A. The Ridgeline Pipeline System is a 187-mile, 24-inch-diameter, high-pressure natural gas transmission pipeline extending from Wetzel County, West Virginia to Greene County, Pennsylvania. The pipeline was designed and constructed to provide reliable, high-volume natural gas transportation service from production areas in the prolific Marcellus and Utica shale formations in northern West Virginia to market delivery points in southwestern Pennsylvania.
The pipeline's receipt point is the Wetzel County Interconnect, located in Wetzel County, West Virginia, at approximate coordinates 39.6120° N, 80.7540° W. The delivery point is the Waynesburg Compressor Station, located in Greene County, Pennsylvania, at approximate coordinates 39.8965° N, 80.1810° W.
The Ridgeline Pipeline System has a design capacity of 1.2 billion cubic feet per day ("Bcf/d"), which is equivalent to 1,200,000 dekatherms per day ("Dth/d") at an assumed BTU content of 1,000 BTU per cubic foot. Current throughput is approximately 680 million cubic feet per day ("MMcf/d"), representing approximately 56.67% utilization of design capacity. I note that throughput has been steadily increasing since the pipeline's in-service date as additional shippers have contracted for capacity and as upstream production volumes in the receipt area have grown.
The pipeline system includes three compressor stations:
1. Wetzel Station, located near the receipt point in Wetzel County, West Virginia, with installed compression of 15,000 horsepower ("HP");
2. Mannington Station, located at approximately milepost 78 near Mannington, Marion County, West Virginia, with installed compression of 15,000 HP; and
3. Waynesburg Station, located at the delivery point in Greene County, Pennsylvania, with installed compression of 15,000 HP.
The aggregate installed compression across the three stations is 45,000 HP.
The Ridgeline Pipeline System was placed in service on October 1, 2021. The original construction cost of the pipeline system was $587.2 million, as recorded on Ridgeline's books and records. The system was constructed over a period of approximately twenty-four months, commencing in November 2019, following the receipt of a certificate of public convenience and necessity from this Commission in Docket No. CP19-258-000, issued on September 12, 2019.
Ridgeline provides open-access transportation service under its FERC Gas Tariff, Original Volume No. 1, filed pursuant to Section 284.221 of the Commission's regulations (18 C.F.R. § 284.221) and Part 284, Subpart G. The pipeline is subject to the Commission's regulatory authority under Sections 4, 5, and 7 of the Natural Gas Act, 15 U.S.C. §§ 717c, 717d, and 717f, and the Commission's implementing regulations at 18 C.F.R. Parts 154, 157, and 284.
III. TEST YEAR AND ACCOUNTING BASIS
A. Selection of Test Year
Q. What test year has Ridgeline selected for purposes of this rate filing?
A. Ridgeline has selected the twelve-month period ended March 31, 2022 as the test year for this rate filing. I will refer to this period as the "test year" or "test period" throughout my testimony.
Q. Why did Ridgeline select this particular test year?
A. The selection of the test year ended March 31, 2022 is appropriate for several reasons. First, this test year captures the first full six months of pipeline operations following the Ridgeline Pipeline System's in-service date of October 1, 2021. The period from October 1, 2021 through March 31, 2022 represents the initial operational period of the pipeline, during which time the system's cost structure stabilized and recurring operational costs became identifiable and measurable.
Second, because the Ridgeline Pipeline System was not in service for the entirety of the twelve-month test year, Ridgeline has annualized certain test-year costs where appropriate to reflect a full year of operations. This annualization methodology is consistent with the Commission's longstanding policy of permitting pipelines to annualize costs that are subject to partial-year distortions, particularly in the context of newly constructed facilities. The specific annualization adjustments are documented in the workpapers filed as Exhibit N.
Third, the test year ended March 31, 2022 was the most recent twelve-month period for which complete, audited financial data was available at the time Ridgeline prepared and filed its application in this proceeding. Ridgeline's financial statements for the period ended March 31, 2022 have been audited by Ashford & McBride LLP, and the workpapers supporting this filing are derived from those audited financial records.
Q. Are the test-year data consistent with FERC accounting requirements?
A. Yes. The test-year data presented in my testimony and supporting exhibits are maintained in accordance with the Uniform System of Accounts prescribed by this Commission under 18 C.F.R. Part 201. Ridgeline maintains its books and records on an accrual basis in conformity with generally accepted accounting principles ("GAAP") as modified by the FERC Uniform System of Accounts. The data are also consistent with the information reported in Ridgeline's FERC Form No. 2 annual report for the relevant period, extracts of which are included in Exhibit P.
B. Adjustments to Test-Year Data
Q. Has Ridgeline made any adjustments to the actual test-year data?
A. Yes. Ridgeline has made certain adjustments to the actual test-year data to derive the adjusted test-year cost of service. These adjustments are of two principal types:
First, Ridgeline has applied known and measurable adjustments consistent with the Commission's longstanding policy. Known and measurable adjustments reflect changes in costs or revenues that are certain to occur and that are capable of reasonable quantification. These adjustments ensure that the test-year cost of service reflects the costs that the pipeline will actually incur on a going-forward basis. Examples of known and measurable adjustments in this filing include adjustments to reflect contractual escalations in lease and service agreements that took effect after the test-year end, and adjustments to reflect changes in staffing levels that were implemented and are now ongoing.
Second, Ridgeline has applied normalization adjustments to account for the partial-year nature of pipeline operations during the test year. As noted above, the Ridgeline Pipeline System was placed in service on October 1, 2021, which means that only six months of operational data fall within the twelve-month test year. To avoid understating costs that will recur on an annual basis, Ridgeline has annualized the six months of operational data to derive twelve-month equivalents for certain cost categories, including O&M expense and compressor station fuel and power costs. These annualization adjustments are documented in Exhibit N.
Q. Has Ridgeline excluded any non-recurring or extraordinary items from the test-year data?
A. Yes. Consistent with Commission policy, Ridgeline has identified and excluded certain non-recurring and extraordinary items from the test-year cost of service. Non-recurring items are costs that are not expected to recur in the normal course of business, and their inclusion would distort the ongoing cost of service. Specifically, Ridgeline has excluded $1.24 million in one-time startup and commissioning costs associated with the initial in-service of the pipeline system that were incurred during October and November 2021. Ridgeline has also excluded $0.38 million in costs associated with a non-recurring environmental remediation at the Mannington Station site that was completed in January 2022. These exclusions are detailed in Exhibit N.
Q. Are all test-year adjustments documented in the supporting workpapers?
A. Yes. All adjustments to the test-year data, including known and measurable adjustments, normalization adjustments, and exclusions of non-recurring items, are fully documented in the supporting workpapers filed as Exhibit N. Each adjustment is identified, explained, quantified, and supported with source documentation.
IV. RATE BASE
A. Overview
Q. What is Ridgeline's total rate base as filed in this proceeding?
A. Ridgeline's total rate base as filed is $612.40 million. The rate base represents the total investment on which Ridgeline is entitled to earn a reasonable return, computed in accordance with the Commission's regulations and established precedent.
Q. What are the principal components of the rate base?
A. The rate base consists of the following principal components: (1) Net Plant in Service, which is Gross Plant in Service less Accumulated Depreciation; (2) Working Capital Allowance; (3) Accumulated Deferred Income Taxes ("ADIT"), which reduces the rate base; and (4) Other Rate Base Items, including gas stored underground, prepayments, and materials and supplies. Each of these components is discussed in detail below.
B. Gross Plant in Service
Q. What is the Gross Plant in Service included in Ridgeline's rate base?
A. Gross Plant in Service is $587.20 million. This amount represents the original construction cost of the Ridgeline Pipeline System as recorded on Ridgeline's books and records. The $587.20 million includes all costs that are properly capitalizable under the FERC Uniform System of Accounts and that were incurred in connection with the design, engineering, procurement, construction, and commissioning of the pipeline system.
Q. What are the major components of the Gross Plant in Service?
A. The Gross Plant in Service of $587.20 million consists of the following major functional categories of plant:
• Pipeline Facilities — This category includes the 187 miles of 24-inch-diameter, high-pressure natural gas transmission pipeline, including all pipe, fittings, valves, cathodic protection systems, pipeline coating, and associated construction costs. Pipeline facilities represent the largest single component of Gross Plant in Service.
• Compressor Station Facilities — This category includes the three compressor stations (Wetzel Station, Mannington Station, and Waynesburg Station), comprising 45,000 HP of aggregate installed compression. The compressor station costs include the compressor units, gas turbine drivers, station piping, buildings, electrical systems, and all associated construction costs.
• Metering and Regulation Equipment — This category includes the metering and regulation facilities at the receipt and delivery points, including ultrasonic flow meters, gas chromatographs, pressure regulation equipment, and associated control systems.
• SCADA and Communications Systems — This category includes the Supervisory Control and Data Acquisition system, fiber optic communication lines, remote terminal units, and the central control facility.
• Rights-of-Way — This category includes the costs of acquiring permanent and temporary easements along the 187-mile pipeline route traversing Wetzel, Marion, and Monongalia Counties in West Virginia and Greene County in Pennsylvania.
• Land — This category includes the cost of land acquired in fee simple for the three compressor station sites and for the metering and regulation facilities.
A detailed breakdown of Gross Plant in Service by functional account is provided in Exhibit L.
Q. What is the basis for the plant values?
A. The plant values are recorded at historical cost, which is the actual cost incurred by Ridgeline to construct the pipeline system. Historical cost is the standard basis for plant valuation under the FERC Uniform System of Accounts and under the Commission's rate-setting methodology. The construction costs have been audited by Ashford & McBride LLP and are reconciled to Ridgeline's books and records and to the amounts reported in Ridgeline's FERC Form No. 2 annual report.
C. Accumulated Depreciation
Q. What is the Accumulated Depreciation included in the rate base calculation?
A. Accumulated Depreciation as of the test year ended March 31, 2022 is $23.49 million.
Q. How was the Accumulated Depreciation computed?
A. Accumulated Depreciation is computed using the straight-line method at an annual depreciation rate of 2.5%, applied to the Gross Plant in Service of $587.20 million. The Ridgeline Pipeline System was placed in service on October 1, 2021. For the period from the in-service date through the end of the test year on March 31, 2022, which represents six months of operation, the depreciation provision would be calculated as $587.20 million × 2.5% × (6/12) = $7.34 million for the partial year.
The total Accumulated Depreciation of $23.49 million as filed includes this partial-year provision along with prior period adjustments that are detailed in the supporting workpapers. These prior period adjustments reflect certain reclassifications and corrections to the depreciation accounts that were identified during the audit process and that are documented in Exhibit D. The depreciation rate of 2.5% is discussed further in Section VI of my testimony.
D. Net Plant in Service
Q. What is the Net Plant in Service?
A. Net Plant in Service is $563.71 million, computed as Gross Plant in Service of $587.20 million less Accumulated Depreciation of $23.49 million. Net Plant in Service represents the undepreciated original cost of the pipeline system and is the largest component of Ridgeline's rate base.
E. Working Capital Allowance
Q. What is the Working Capital Allowance included in Ridgeline's rate base?
A. The Working Capital Allowance included in Ridgeline's rate base is $18.64 million.
Q. How was the Working Capital Allowance derived?
A. The Working Capital Allowance is derived from multiple components. As a starting point, the Commission's traditional formula provides for a working capital allowance equal to one-eighth (1/8) of annual O&M expense plus A&G expense. Under this formula, the basic working capital allowance would be computed as follows:
1/8 × ($12.44 million O&M + $4.82 million A&G) = 1/8 × $17.26 million = $2.16 million (rounded)
However, the total Working Capital Allowance of $18.64 million includes additional working capital components beyond the basic 1/8 formula. These additional components include:
• Cash working capital — computed on the basis of a lead-lag study that examines the timing differences between when Ridgeline receives revenues from its shippers and when it must pay its operating expenses, including fuel, power, labor, materials, and other costs. The cash working capital study results are detailed in Exhibit J.
• Prepaid expenses — including prepaid insurance premiums, prepaid property taxes, and other prepaid items that represent amounts paid by Ridgeline in advance of the period to which they relate.
• Other working capital items — including deposits and other current asset balances that support pipeline operations.
The detailed computation of the Working Capital Allowance, including the cash working capital study methodology and results, is set forth in Exhibit J.
F. Accumulated Deferred Income Taxes (ADIT)
Q. What is the Accumulated Deferred Income Taxes amount included in the rate base?
A. The Accumulated Deferred Income Taxes, or ADIT, balance is negative $12.45 million, which serves to reduce the rate base. This deduction from rate base is appropriate and required under the Commission's regulatory framework.
Q. What does the ADIT balance represent?
A. The ADIT balance represents the cumulative timing differences between book depreciation (straight-line at 2.5%) and tax depreciation (accelerated under the Modified Accelerated Cost Recovery System, or "MACRS," as applicable under the Internal Revenue Code). Because Ridgeline claims accelerated depreciation for income tax purposes, the pipeline system generates larger tax deductions in the early years of its life than are reflected in the book depreciation expense. This creates a timing difference that results in deferred income taxes.
Under the Commission's normalization requirements and well-established precedent, ADIT is deducted from rate base because it represents cost-free capital provided by ratepayers through the tax timing differences. The deduction of ADIT from rate base ensures that ratepayers receive the benefit of the tax deferral and that the pipeline does not earn a return on capital that is effectively provided at no cost.
The ADIT balance has been computed in accordance with the Commission's normalization requirements, consistent with IRS normalization rules, and is detailed in Exhibit K. I also discuss the relationship between ADIT and the income tax allowance in Section VIII of my testimony.
G. Other Rate Base Items
Q. What Other Rate Base Items are included in the rate base?
A. Other Rate Base Items total $42.50 million. These items are properly includable in rate base because they represent investments that are necessary for the provision of jurisdictional transportation service. The Other Rate Base Items consist of the following components:
• Gas Stored Underground — $28.75 million. This amount represents the cost of gas held in underground storage facilities that is necessary for operational purposes, including line pack and system balancing. The gas stored underground is valued at the weighted average cost of acquisition, consistent with Commission policy.
• Prepayments — $6.30 million. This amount represents prepaid expenses that are not already captured in the Working Capital Allowance, including long-term prepayments for rights-of-way maintenance, multi-year service contracts, and other advance payments.
• Materials and Supplies — $7.45 million. This amount represents the cost of spare parts, pipe, fittings, valves, and other materials held in inventory for use in the operations and maintenance of the Ridgeline Pipeline System. These materials are necessary to ensure the reliable and safe operation of the system and to support timely repairs and planned maintenance activities.
Each of these components is supported by documentation in Exhibit B.
H. Rate Base Summary Table
Q. Please summarize the components of Ridgeline's rate base.
A. The following table summarizes the components of Ridgeline's rate base as filed:
The total rate base of $612.40 million represents the investment on which Ridgeline seeks to earn a just and reasonable return. Each component is supported by Ridgeline's books and records, has been prepared in accordance with the FERC Uniform System of Accounts, and is documented in the exhibits and workpapers filed with the application.
V. CAPITAL STRUCTURE AND COST OF CAPITAL
A. Proposed Capital Structure
Q. What capital structure is Ridgeline proposing for purposes of this rate filing?
A. Ridgeline proposes a capital structure of 55% equity and 45% debt for purposes of computing the weighted average cost of capital and the return on rate base.
Q. What is the basis for the proposed 55% equity / 45% debt capital structure?
A. The proposed capital structure is based on the actual capitalization of Ridgeline and its parent, DEH, adjusted to reflect a reasonable hypothetical capital structure that is consistent with Commission precedent for new pipeline facilities.
The actual financing of the Ridgeline Pipeline System, which I describe in detail below, involved a combination of debt and equity. The total construction cost of $587.20 million was funded through a Senior Secured Credit Facility providing $400 million in term loan borrowings, $150 million in Second Lien Senior Secured Notes, and an equity contribution of $37.20 million from DEH. On a gross basis, this financing mix represents approximately 93.7% debt and 6.3% equity, which is substantially more leveraged than would be appropriate for rate-setting purposes.
However, the Commission has long recognized that the actual financing of a particular pipeline project does not necessarily dictate the capital structure used for rate-setting purposes. The Commission has permitted pipelines to use a hypothetical capital structure when the pipeline's actual capital structure does not reflect the overall financial posture of the pipeline and its parent, or when the actual structure is not representative of the capital structure that a pipeline of similar risk would maintain on a standalone basis. See, e.g., Vireo Industries., 84 FERC ¶ 61,084 (1998); Northwest Pipeline Corp., 87 FERC ¶ 61,266 (1999).
In this case, the 55%/45% equity-to-debt ratio reflects the consolidated capital structure of DEH, which maintains an enterprise-level capital structure of approximately 55% equity and 45% debt. Ridgeline relies on the financial strength and creditworthiness of DEH for its ability to access capital markets and maintain favorable borrowing terms. The Commission has recognized that it is appropriate to look to the parent company's capital structure when the subsidiary's actual structure is heavily leveraged due to project financing arrangements. The proposed 55%/45% structure is also within the range of capital structures maintained by the proxy group of comparable pipeline companies analyzed by Dr. Braswell in his testimony on return on equity.
B. Financing of the Ridgeline Pipeline System
Q. Please describe the financing of the Ridgeline Pipeline System in detail.
A. The total construction cost of the Ridgeline Pipeline System was $587.20 million. This cost was financed through the following sources:
Senior Secured Credit Facility. On September 15, 2021, Ridgeline entered into a Senior Secured Credit Facility Agreement (the "Credit Agreement") providing for a $400 million term loan and a $75 million revolving credit facility.
