Organization, Consolidation and Presentation of Financial Statements [Abstract]
Description of Business and Basis of Presentation	Description of Business and Basis of Presentation Description of Business Enviva Partners, LP, together with its subsidiaries (“we,” “us,” “our” or the “Partnership”), supplies utility-grade wood pellets primarily to major power generators under long-term, take-or-pay off-take contracts. We procure wood fiber and process it into utility-grade wood pellets and load the finished wood pellets into railcars, trucks and barges for transportation to deep-water marine terminals, where they are received, stored and ultimately loaded onto oceangoing vessels for delivery to our principally European, and increasingly Japanese, customers under long-term, take-or-pay contracts. As of September 30, 2019 , we owned and operated seven industrial-scale wood pellet production plants located in the Mid-Atlantic and Gulf Coast regions of the United States. In addition to the volumes from our plants, we also procure wood pellets from third parties and Enviva Pellets Greenwood, LLC (“Greenwood”), a wholly owned subsidiary of Enviva JV Development Company, LLC (the “Second JV”), a limited liability company owned by Enviva Holdings, LP (together with its wholly owned subsidiaries Enviva MLP Holdco, LLC and Enviva Development Holdings, LLC, where applicable, the “sponsor”) and John Hancock Life Insurance Company (U.S.A.) and certain of its affiliates. Greenwood owns a wood pellet production plant in Greenwood, South Carolina (the “Greenwood plant”). Wood pellets are exported from our wholly owned dry-bulk, deep-water marine terminal in Chesapeake, Virginia (the “Chesapeake terminal”) and terminal assets in Wilmington, North Carolina (the “Wilmington terminal”), and from third-party deep-water marine terminals in Mobile, Alabama and Panama City, Florida, under a short-term and a long-term contract, respectively. Basis of Presentation The unaudited financial statements and notes have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X of the Securities Exchange Act of 1934. Accordingly, they do not include all of the information and notes required by GAAP for complete financial statements. In the opinion of management, all adjustments and accruals necessary for a fair presentation have been included. All such adjustments and accruals are of a normal and recurring nature unless disclosed otherwise. All intercompany balances and transactions have been eliminated in consolidation. The results reported in the financial statements are not necessarily indicative of the results that may be reported for the entire year. We entered into an agreement with our sponsor dated and effective as of September 30, 2019 pursuant to which the parties agreed to the right of set off of related-party accounts receivable and accounts payable; consequently, we intend to set off related-party receivables and payables, which are reflected net in related-party payables, in accordance with the agreement. As of December 31, 2018, related-party accounts receivable and accounts payable were not intended to be set off and were reflected separately in current assets and current liabilities. For the nine months ended September 30, 2018, certain amounts on the statements of cash flows have been reclassified from proceeds and payments on revolving credit commitments, net, to proceeds from senior secured revolving credit facility and payments on senior secured revolving credit facility to conform to current period presentation. The unaudited financial statements and notes should be read in conjunction with the audited financial statements and notes included in our Annual Report on Form 10-K for the year ended December 31, 2018 . Enviva Wilmington Holdings, LLC In April 2019, we acquired from the sponsor all of the issued and outstanding Class B Units in Enviva Wilmington Holdings, LLC (the “First JV”), a limited liability company owned by the sponsor and John Hancock Life Insurance Company (U.S.A.) and certain of its affiliates (collectively, the “Hancock Member”). As of April 2, 2019, we began to consolidate the First JV as a variable interest entity of which we are the primary beneficiary. As managing member, we have the sole power to direct the activities that most impact the economics of the First JV and substantially all of the activities are conducted on our behalf. Additionally, as the Class B Units represented a controlling interest in the First JV, we accounted for the First JV as a consolidated subsidiary, not as a joint venture. The First JV owns a plant in Hamlet, North Carolina (the “Hamlet plant”) and a firm, 15 -year take-or-pay off-take contract with nearly 1.0 million metric tons per year (“MTPY”) of wood pellets, following a ramp period. On the date of our acquisition of the sponsor’s Class B Units in the First JV (collectively, the “JV 1.0 Drop-Down”): • We commenced an associated terminal services agreement to handle contracted volumes from the Hamlet plant. • We entered into an agreement with the sponsor, pursuant to which (1) the sponsor will guarantee certain cash flows from the Hamlet plant until June 30, 2020, (2) the sponsor will reimburse us for construction cost overruns in excess of budgeted capital expenditures for the Hamlet plant, subject to certain exceptions, (3) we will pay to the sponsor quarterly incentive payments for any wood pellets produced by the Hamlet plant in excess of forecast production levels through June 30, 2020, and (4) the sponsor will retain liability for certain claims payable, if any, by the First JV (the “Make-Whole Agreement”). • The First JV entered into an agreement with Enviva Management Company, LLC, a Delaware limited liability company and wholly owned subsidiary of the sponsor (“Enviva Management”), to waive the obligation to pay an aggregate of approximately $2.7 million of management fees payable to Enviva Management under the management services agreement (the “First JV MSA”) between the First JV and Enviva Management with respect to the period from the date of acquisition of the Hamlet plant until July 1, 2019 (the “First JV MSA Fee Waiver”). • We entered into an agreement with Enviva Management to waive our obligation to pay an aggregate of approximately $13.0 million in fees payable under our management services agreement (the “EVA MSA,” and together with the First JV MSA, the “MSAs”) with Enviva Management with respect to the period from the date of the JV 1.0 Drop-Down through the second quarter of 2020 (the “First EVA MSA Fee Waiver”). • The sponsor assigned to us all of its rights and obligations under a credit agreement between the First JV, as borrower, and the sponsor, as lender (the “First JV Revolver”). On the date of assignment, $4.1 million was outstanding from the First JV to the sponsor. • The First JV entered into an interim services agreement (the “ISA”) with Enviva Hamlet Operator, LLC, a wholly-owned subsidiary of our sponsor (“Hamlet Operator”) pursuant to which Hamlet Operator, as an independent contractor, will manage, operate, maintain and repair the Hamlet plant and provide other services to the First JV for the period from July 1, 2019 through June 30, 2020 in exchange for a fixed fee per metric ton of wood pellets produced by the Hamlet plant during such period and delivered at place. Under and during the term of the ISA, Hamlet Operator will (1) pay all operating and maintenance expenses at the Hamlet plant, (2) cover all reimbursable general and administrative expenses associated with the Hamlet plant and (3) pay other costs and expenses incurred by the Hamlet plant to produce and sell the wood pellets delivered to the Wilmington terminal from the Hamlet plant. The sponsor guarantees all obligations of Hamlet Operator under the ISA. Fees to Enviva Management through the MSAs are expensed as incurred and, to the extent any amount is associated with the First JV MSA Fee Waiver and the First EVA MSA Fee Waiver, the related amount is recorded as an increase to partners’ capital. The $165.0 million purchase price for the JV 1.0 Drop-Down consisted of (1) a cash payment of $24.7 million , net of a purchase price adjustment of $0.3 million , (2) the issuance of 1,681,237 unregistered common units at a value of $29.74 per unit, or $50.0 million of common units, (3) $50.0 million in cash paid on June 28, 2019, (4) $40.0 million in cash to be paid on January 2, 2020 and (5) the elimination of $3.7 million of net related-party receivables and payables included in the net assets of the First JV on the date of acquisition. As the holder of the Class B Units, we became a member of the First JV (the “Enviva Member”) on the acquisition date. During the three and nine months ended September 30, 2019 , we incurred and expensed $0.1 million and $1.3 million , respectively, in acquisition costs to acquire the First JV which were recognized as general and administrative expenses. As the Enviva Member, we are the managing member and primary beneficiary of the First JV. We included all accounts of the First JV in our consolidated results as of April 2, 2019 as the Class B Units represent a controlling interest in the First JV and are generally unrestricted as it relates to the management of the assets and cash flows of the First JV; however, we cannot cause the First JV to incur indebtedness in excess of $60.0 million . The JV 1.0 Drop-Down was an asset acquisition of entities under common control and accounted for on the carryover basis of accounting. Pursuant to the First JV MSA, Enviva Management provides services to the First JV, including those necessary or incidental to the operation and management of the First JV’s business. We are responsible for managing the activities of the First JV, including the development, construction and operation of the Hamlet plant.

Accounting Policies [Abstract]
Significant Accounting Policies	Significant Accounting Policies During interim periods, we follow the accounting policies disclosed in our Annual Report on Form 10-K for the year ended December 31, 2018 except for our adoption on and as of January 1, 2019 of Financial Accounting Standards Board (“FASB”) Accounting Standards Update (“ASU”) 2016-02, Leases (Topic 842) and ASU 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities. Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make judgments, estimates and assumptions that affect the amounts reported in our unaudited financial statements and accompanying notes. Actual results could differ materially from those estimates. Accounting Standards Adopted Leases ASU 2016-02 established a right-of-use (“ROU”) model that requires lessees to recognize a ROU asset and corresponding lease liability on the balance sheet for all leases with a term of longer than 12 months and classify leases as operating or finance. Operating lease expense is recorded in a single financial statement line item on a straight-line basis over the lease term. Amortization of the ROU asset is the calculated difference between straight-line lease expense and the accretion of interest on the lease liability each period. We adopted ASU 2016-02 on and as of January 1, 2019 using the modified retrospective transition method, which we applied to all leases existing at the date of initial application of the ASU. We elected to use the effective date as the date of initial application, as opposed to the beginning of the earliest comparative period presented in the financial statements; consequently, financial information and disclosures are not presented under the new standard for periods prior to January 1, 2019. We elected the package of three practical expedients under the transition guidance within the new standard, which permitted us to reassess our prior conclusions under the previous guidance concerning lease identification, lease classification and initial direct leasing costs. We elected the practical expedient to not evaluate existing or expired land easements that were not accounted for as leases under previous guidance. We did not, however, elect the separate practical expedient pertaining to the use of hindsight in determining the lease term for existing leases. We have a significant contract containing both lease and nonlease components, which are accounted for separately. As this contract has fixed payments, the allocation of lease and nonlease components is based on relative standalone price. The adoption of the new standard as of January 1, 2019 resulted in the recognition of operating lease ROU assets of $27.4 million , net of $2.1 million of deferred rent liabilities existing as of December 31, 2018, and operating lease liabilities of $29.5 million for operating leases related to real estate, machinery and equipment and other operating leases with terms of longer than 12 months. The amounts recognized as of January 1, 2019 were based on the present value of the remaining minimum rental payments under previous leasing standards for existing operating leases. The classification of a lease affects the pattern and classification of expense recognition in the income statement, which is unchanged from under the previous accounting method. The adoption of the new standard did not change our accounting for finance leases (which were described as “capital leases” under the previous standard) or impact our results of operations and cash flows. See Note 9, Leases . Derivative Instruments We adopted ASU 2017-12 on and as of January 1, 2019 using the modified retrospective method, which requires the recognition of the cumulative effect of the change on the opening balance of each affected component of equity in the statement of changes in partner’s capital as of the date of adoption of the new standard. Upon adoption of ASU 2017-12, we no longer measure and recognize ineffectiveness related to designated and qualifying cash flow hedges in earnings; as a result, any ineffectiveness is included in accumulated other comprehensive income. On January 1, 2019, we recorded a nominal cumulative effect adjustment to accumulated other comprehensive income and common units in partners’ capital. See Note 10, Derivatives. Recently Issued Accounting Standards not yet Adopted Currently, there are no recently issued accounting standards not yet adopted by us that we expect to be reasonably likely to materially impact the financial position, results of operations or cash flows of the Partnership.

Transactions Between Entities Under Common Control
Transactions Between Entities Under Common Control	Transactions Between Entities Under Common Control The JV 1.0 Drop-Down was an asset acquisition of entities under common control and accounted for on the carryover basis of accounting. Accordingly, the consolidated financial statements for the period beginning April 2, 2019 reflect the acquisition. The purchase price for the JV 1.0 Drop-Down consisted of $165.0 million , which included an initial cash payment of $24.7 million , net of purchase price adjustment of $0.3 million , and the issuance of 1,681,237 unregistered common units at a value of $29.74 per unit, or $50.0 million of common units, $50.0 million in cash, paid on June 28, 2019, and $40.0 million in cash, which will be paid on January 2, 2020 as the third and final payment. The changes in net assets at carryover basis on April 2, 2019 included $121.6 million net assets of the First JV, net of the elimination of $3.7 million of net related-party receivables and payables. The following table outlines the changes in consolidated net assets resulting from the JV 1.0 Drop-Down on April 2, 2019. Assets: Cash and cash equivalents $ 3,426 Related-party receivables 945 Prepaid expenses and other current assets 22 Property, plant and equipment, net 140,446 Other long-term assets 8 Total assets 144,847 Liabilities: Accounts payable 6,395 Related-party payables 1,923 Accrued and other current liabilities 14,965 Finance lease obligations 3 Total liabilities 23,286 Net assets contributed to Partnership $ 121,561 Related-Party Transactions Related-party transaction amounts included on the unaudited condensed consolidated statements of operations were as follows: Three Months Ended Nine Months Ended 2019 2018 2019 2018 Other revenue $ 496 $ 1,042 $ 1,323 $ 3,346 Cost of goods sold 26,300 20,133 80,921 56,184 General and administrative expenses 6,486 4,113 19,488 11,628 Management Services Agreements Pursuant to the MSAs, Enviva Management provides us with operations, general administrative, management and other services. We are required to reimburse Enviva Management for the amount of all direct or indirect internal or third-party expenses incurred by Enviva Management in connection with the provision of such services. The MSAs include rent-related amounts for non-cancelable operating leases for office space in Maryland and North Carolina held by the sponsor. Under the First JV MSA, to the extent allocated costs exceed the annual management fee, the additional costs are recorded with an increase to partners’ capital. During the three and nine months ended September 30, 2019 , $17.8 million and $51.5 million , respectively, related to the MSAs was included in cost of goods sold and $6.5 million and $19.5 million , respectively, was included in general and administrative expenses. As of September 30, 2019 , $1.7 million incurred under the MSAs was included in finished goods inventory. During the three and nine months ended September 30, 2018 , $13.4 million and $35.9 million , respectively, related to the MSAs was included in cost of goods sold and $4.1 million and $11.6 million , respectively, was included in general and administrative expenses. During the three and nine months ended September 30, 2019 , $0.8 million and $1.7 million , respectively, of fees expensed under the First JV MSA were waived and recorded as an increase to partner’s capital. JV 1.0 Drop-Down Agreements The agreements we entered into on the date of acquisition of the First JV resulted in the following amounts being recorded in our financial statements since the date of acquisition. During the three and nine months ended September 30, 2019 , $11.6 million and $20.5 million , respectively, were recorded as an increase to partners’ capital and $0.1 million and $0.7 million , respectively, were recorded as a net reduction in cost of goods sold. These increases to partners’ capital are comprised of expenses waived under the EVA MSA Fee Waiver and the First JV MSA Fee Waiver and reimbursement of construction cost overruns in excess of budgeted capital expenditures for the Hamlet plant. The net reduction in cost of goods sold is comprised of the cost of cover deficiency fee from the Hamlet Operator under the ISA not producing enough pellets at Hamlet, offset by the agreed-upon price due to the Hamlet Operator for the pellets from Hamlet that we have sold. Second EVA MSA Fee Waiver In June 2019, we entered into an additional agreement (the “Second EVA MSA Fee Waiver”) with Enviva Management pursuant to which we received a $5.0 million waiver of EVA MSA fees through September 30, 2019, as consideration for an assignment of two shipping contracts to our sponsor to rebalance our and our sponsor’s respective shipping obligations under existing off-take contracts. During the three and nine months ended September 30, 2019 , $2.3 million and $5.0 million , respectively, of EVA MSA fees expensed were waived and recorded as an increase to partners’ capital pursuant to the Second EVA MSA Fee Waiver. During the three and nine months ended September 30, 2018 , no EVA MSA fees were waived pursuant to the Second EVA MSA Fee Waiver. Wilmington Drop-Down - Deferred Consideration In October 2017, we acquired from the First JV all of the issued and outstanding limited liability company interests in Enviva Port of Wilmington, LLC (“Wilmington”), which owns the Wilmington terminal assets (the “Wilmington Drop-Down”), for total consideration of $130.0 million , subject to certain conditions. The Wilmington Drop-Down included the Wilmington terminal assets and a long-term terminal services agreement with our sponsor (the “Holdings TSA”) to handle throughput volumes sourced from Greenwood. The purchase price included $74.0 million of deferred consideration, which was paid in full in April 2019 and consisted of $24.3 million in cash, of which $22.8 million was distributed to the Hancock Member and the issuance of 1,691,627 common units, or approximately $49.7 million in common units, which were distributed to the Hancock Member. The $74.0 million of deferred consideration was reflected on the condensed consolidated balance sheets as of December 31, 2018 . Greenwood Contract In February 2018, we entered into a contract with Greenwood to purchase wood pellets produced by the Greenwood plant through March 2022 (the “Greenwood contract”) and we have a take-or-pay obligation with respect to 550,000 MTPY of wood pellets from July 2019 through March 2022. In July 2019, we entered into an amendment whereby the commencement of the take-or-pay obligation date was deferred from July 2019 to January 2020. During the three and nine months ended September 30, 2019 , we purchased $11.3 million and $35.5 million , respectively, of wood pellets and recorded a cost of cover deficiency fee from Greenwood of approximately $1.0 million and $4.3 million , respectively, from Greenwood as Greenwood was unable to satisfy certain commitments. Of the net $8.6 million and $29.5 million , respectively, $9.7 million and $33.8 million , respectively, is included in cost of goods sold and $1.5 million is included in finished goods inventory as of September 30, 2019 . During the three and nine months ended September 30, 2018 , we purchased $8.5 million and $16.8 million , respectively, of wood pellets from Greenwood, which is included in cost of goods sold. Holdings TSA The Wilmington Drop-Down included a long-term terminal services agreement with our sponsor (the “Holdings TSA”). Pursuant to the Holdings TSA, our sponsor agreed to deliver a minimum of 125,000 MT of wood pellets per quarter for receipt, storage, handling and loading services by the Wilmington terminal and pay a fixed fee on a per-ton basis for such terminal services. The Holdings TSA remains in effect until September 1, 2026. We did no t record any terminal services revenue from our sponsor during the three months ended September 30, 2018 . During the nine months ended September 30, 2018 , we recorded $0.8 million as terminal services revenue from our sponsor, which is included in other revenue. In February 2018, our sponsor amended and assigned the Holdings TSA to Greenwood. Deficiency payments are due to Wilmington if quarterly minimum throughput requirements are not met. During the three and nine months ended September 30, 2019 and 2018 , we recorded $0.5 million and $1.3 million , respectively, and $0.5 million and $2.0 million , respectively, of deficiency fees from Greenwood, which is included in other revenue. In September 2018, Hurricane Florence impacted the rail line on which wood pellets are typically transported from the Greenwood plant to the Wilmington terminal. As a result, Greenwood was unable to satisfy certain commitments under the Holdings TSA and the Greenwood contract and agreed to pay $1.8 million to us as deficiency fees in consideration of these commitments. Consideration of $0.5 million related to the Holdings TSA was included in other revenue and $1.3 million related to the Greenwood contract was included as a reduction of cost of goods sold. Biomass Option Agreement – Enviva Holdings, LP Enviva, LP purchased none and $1.7 million of wood pellets from the sponsor during the three and nine months ended September 30, 2018 , respectively, pursuant to a biomass option agreement. The wood pellet purchase amounts are included in cost of goods sold. The biomass option agreement terminated in accordance with its terms in March 2018. Enviva FiberCo, LLC We purchase raw materials from Enviva FiberCo, LLC (“FiberCo”), a wholly owned subsidiary of our sponsor. During the three and nine months ended September 30, 2019 , purchased raw materials, net of cost of cover deficiency fees from FiberCo, were immaterial and $0.6 million , respectively. During the three and nine months ended September 30, 2018 , we purchased raw materials of $1.8 million and $3.5 million , respectively, from FiberCo. No cost of cover deficiency fees from FiberCo were recognized during the three and nine months ended September 30, 2018 . Long-Term Incentive Plan Vesting As of September 30, 2019 , we had an insignificant amount included in related-party payables related to withholding tax amounts due to Enviva Management associated with the vesting of time-based phantom units under the Enviva Partners, LP Long-Term Incentive Plan (“LTIP”).

Revenue from Contract with Customer [Abstract]
Revenue	Revenue We disaggregate our revenue into two categories: product sales and other revenue. Other revenue includes fees associated with customer requests to cancel, defer or accelerate shipments in satisfaction of the related performance obligation and third- and related-party terminal services fees. These categories best reflect the nature, amount, timing and uncertainty of our revenue and cash flows. Performance Obligations As of September 30, 2019 , the aggregate amount of revenues from contracts with customers allocated to performance obligations that were unsatisfied or partially satisfied was approximately $9.3 billion . This amount excludes forward prices related to variable consideration including inflation and foreign currency and commodity prices. Also, this amount excludes the effects of related foreign currency derivative contracts as they do not represent contracts with customers. As of October 1, 2019, we expect to recognize approximately 2.0% of our remaining performance obligations as revenue during the remainder of 2019, approximately 10.0% in 2020 and the balance thereafter. Our off-take contracts expire at various times through 2040 and our terminal services contracts extend into 2026. Variable Consideration Variable consideration from off-take contracts arises from several pricing features outlined in our off-take contracts, pursuant to which such contract pricing may be adjusted in respect of particular shipments to reflect differences between certain contractual quality specifications of the wood pellets as measured both when the wood pellets are loaded onto ships and unloaded at the discharge port as well as certain other contractual adjustments. Variable consideration from terminal services contracts, which was not material for the three and nine months ended September 30, 2019 and 2018, arises from price increases based on agreed inflation indices and from above-minimum throughput quantities or services. We allocate variable consideration under our off-take and terminal services contracts entirely to each performance obligation to which variable consideration relates. The estimate of variable consideration represents the amount that is not more likely than not to be reversed. For the three and nine months ended September 30, 2019 , we recognized $0.1 million and $0.5 million . respectively, of revenue related to performance obligations satisfied in previous periods. For the three and nine months ended September 30, 2018 , we recognized an insignificant amount of revenue related to performance obligations in previous periods. Contract Balances Accounts receivable related to product sales as of September 30, 2019 and December 31, 2018 were $47.8 million and $51.3 million , respectively. We had no deferred revenue as of September 30, 2019 for future performance obligations associated with off-take contracts. We had $0.3 million of deferred revenue as of December 31, 2018 for future performance obligations associated with off-take contracts.

Inventory Impairment and Asset Disposal	Inventory Impairment and Asset Disposal On February 27, 2018, a fire occurred at the Chesapeake terminal, causing damage to equipment and approximately 43,000 MT of wood pellets (the “Chesapeake Incident”). The Chesapeake terminal returned to operations on June 28, 2018. During the three and nine months ended September 30, 2018 , we incurred $9.7 million and $58.4 million , respectively, in costs as a result of the Chesapeake Incident related to asset impairment, inventory write-off and disposal costs, emergency response costs, asset repair costs and business continuity costs, the latter of which represented incremental costs to commission temporary wood pellet storage and handling and ship loading operations at nearby locations to meet our contractual obligations to our customers. As of September 30, 2018 , we had recovered $48.1 million related to the Chesapeake Incident, which included $1.1 million of lost profits. As of December 31, 2018 , $3.8 million of probable insurance recoveries for the then-remaining costs not yet recovered were included in insurance receivables; we received the $3.8 million in probable insurance recoveries (plus $0.5 million recognized as other income in 2019) in February 2019.

Leases [Abstract]
Leases	Leases We have operating and finance leases related to real estate, machinery, equipment and other assets where we are the lessee. Leases with an initial term of 12 months or less are not recorded on the balance sheet but are recognized as lease expense on a straight-line basis over the applicable lease terms. Amortization of the ROU asset is calculated as the difference between straight-line lease expense and the accretion of interest on the lease liability each period. In addition to fixed lease payments, we have contracts that incur variable lease expense related to usage (e.g. throughput fees, maintenance and repair and machine hours), which are expensed as incurred. Our leases have remaining terms of one to 28 years , some of which include options to extend the leases for up to 5 years . Our leases are generally noncancellable. Certain leases also include options to purchase the leased property. The depreciable life of assets and leasehold improvements are limited by the expected lease term, unless there is a transfer of title or purchase option reasonably certain of exercise. A discount rate is applied to our leases for balance sheet measurement. As rates are not explicitly defined in the operating and finance lease agreements, we use our incremental borrowing rate for purposes of measuring the ROU assets and lease liabilities for recognized leases. This is a secured interest rate which takes into account our credit rating, the term of our leases, as well as the economic environment in which we operate. Each lease uses a secured interest rate with a term commensurate to the identified lease term. Operating leases are included in operating lease ROU assets, accrued and other current liabilities and long-term operating lease liabilities on our condensed consolidated balance sheets. Finance leases are included in property, plant and equipment, current portion of long-term debt and finance lease obligations and long-term debt and finance lease obligations on our condensed consolidated balance sheets. Changes in ROU assets and operating lease liabilities are included net in change in operating lease liabilities on the condensed consolidated statement of cash flows. Operating lease ROU assets and liabilities and finance leases were as follows as of September 30, 2019 : Operating leases: Operating lease right-of-use assets, gross $ 36,964 Accumulated amortization (3,585 ) Operating lease right-of-use assets, net $ 33,379 Current portion of operating lease liabilities $ 1,577 Long-term operating lease liabilities 33,725 Total operating lease liabilities $ 35,302 Finance leases: Property, plant and equipment, gross $ 13,484 Accumulated depreciation (5,870 ) Property plant and equipment, net $ 7,614 Current portion of long-term finance lease obligations $ 4,482 Long-term finance lease obligations 3,237 Total finance lease liabilities $ 7,719 Operating and finance lease costs were as follows: Lease Cost Classification Three Months Ended Nine Months Ended Operating lease cost: Fixed lease cost Cost of goods sold $ 1,269 $ 3,546 Variable lease cost Cost of goods sold 3 29 Short-term lease costs Cost of goods sold 15 15 Total operating lease costs $ 1,287 $ 3,590 Finance lease cost: Amortization of leased assets Depreciation and amortization 1,094 2,578 Variable lease cost Cost of goods sold 4 4 Interest on lease liabilities Interest expense 70 179 Total finance lease costs $ 1,168 $ 2,761 Total lease costs $ 2,455 $ 6,351 Operating and finance lease cash flow information was as follows: Nine Months Ended Cash paid for amounts included in the measurement of lease liabilities: Operating cash flows from operating leases $ 3,715 Operating cash flows from financing leases 179 Financing cash flows from financing leases 2,020 Assets obtained in exchange for lease obligations: Operating leases $ 7,465 Financing leases 5,380 The future minimum lease payments and the aggregate maturities of operating and finance lease liabilities are as follows as of September 30, 2019 : Years Ending December 31, Operating Finance Total Remainder of 2019 $ 1,112 $ 1,415 $ 2,527 2020 4,140 4,358 8,498 2021 3,890 1,814 5,704 2022 3,719 279 3,998 2023 3,710 246 3,956 Thereafter 65,110 92 65,202 Total lease payments 81,681 8,204 89,885 Less: imputed interest (46,379 ) (485 ) (46,864 ) Total present value of lease liabilities $ 35,302 $ 7,719 $ 43,021 The future minimum lease payments as of December 31, 2018 for operating and finance lease liabilities were $73.8 million and $4.8 million , respectively.

Leases with an initial term of 12 months or less are not recorded on the balance sheet but are recognized as lease expense on a straight-line basis over the applicable lease terms. Amortization of the ROU asset is calculated as the difference between straight-line lease expense and the accretion of interest on the lease liability each period. In addition to fixed lease payments, we have contracts that incur variable lease expense related to usage (e.g. throughput fees, maintenance and repair and machine hours), which are expensed as incurred. Our leases have remaining terms of one to 28 years , some of which include options to extend the leases for up to 5 years . Our leases are generally noncancellable. Certain leases also include options to purchase the leased property. The depreciable life of assets and leasehold improvements are limited by the expected lease term, unless there is a transfer of title or purchase option reasonably certain of exercise. A discount rate is applied to our leases for balance sheet measurement. As rates are not explicitly defined in the operating and finance lease agreements, we use our incremental borrowing rate for purposes of measuring the ROU assets and lease liabilities for recognized leases. This is a secured interest rate which takes into account our credit rating, the term of our leases, as well as the economic environment in which we operate. Each lease uses a secured interest rate with a term commensurate to the identified lease term. Operating leases are included in operating lease ROU assets, accrued and other current liabilities and long-term operating lease liabilities on our condensed consolidated balance sheets. Finance leases are included in property, plant and equipment, current portion of long-term debt and finance lease obligations and long-term debt and finance lease obligations on our condensed consolidated balance sheets. Changes in ROU assets and operating lease liabilities are included net in change in operating lease liabilities on the condensed consolidated statement of cash flows. Operating lease ROU assets and liabilities and finance leases were as follows as of September 30, 2019 : Operating leases: Operating lease right-of-use assets, gross $ 36,964 Accumulated amortization (3,585 ) Operating lease right-of-use assets, net $ 33,379 Current portion of operating lease liabilities $ 1,577 Long-term operating lease liabilities 33,725 Total operating lease liabilities $ 35,302 Finance leases: Property, plant and equipment, gross $ 13,484 Accumulated depreciation (5,870 ) Property plant and equipment, net $ 7,614 Current portion of long-term finance lease obligations $ 4,482 Long-term finance lease obligations 3,237 Total finance lease liabilities $ 7,719 Operating and finance lease costs were as follows: Lease Cost Classification Three Months Ended Nine Months Ended Operating lease cost: Fixed lease cost Cost of goods sold $ 1,269 $ 3,546 Variable lease cost Cost of goods sold 3 29 Short-term lease costs Cost of goods sold 15 15 Total operating lease costs $ 1,287 $ 3,590 Finance lease cost: Amortization of leased assets Depreciation and amortization 1,094 2,578 Variable lease cost Cost of goods sold 4 4 Interest on lease liabilities Interest expense 70 179 Total finance lease costs $ 1,168 $ 2,761 Total lease costs $ 2,455 $ 6,351 Operating and finance lease cash flow information was as follows: Nine Months Ended Cash paid for amounts included in the measurement of lease liabilities: Operating cash flows from operating leases $ 3,715 Operating cash flows from financing leases 179 Financing cash flows from financing leases 2,020 Assets obtained in exchange for lease obligations: Operating leases $ 7,465 Financing leases 5,380 The future minimum lease payments and the aggregate maturities of operating and finance lease liabilities are as follows as of September 30, 2019 : Years Ending December 31, Operating Finance Total Remainder of 2019 $ 1,112 $ 1,415 $ 2,527 2020 4,140 4,358 8,498 2021 3,890 1,814 5,704 2022 3,719 279 3,998 2023 3,710 246 3,956 Thereafter 65,110 92 65,202 Total lease payments 81,681 8,204 89,885 Less: imputed interest (46,379 ) (485 ) (46,864 ) Total present value of lease liabilities $ 35,302 $ 7,719 $ 43,021 The future minimum lease payments as of December 31, 2018 for operating and finance lease liabilities were $73.8 million and $4.8 million , respectively.

Derivative Instruments

Derivative Instrument Detail [Abstract]
Derivative Instruments	Derivative Instruments We use derivative instruments to partially offset our business exposure to foreign currency exchange and interest rate risk. We may enter into foreign currency forward and option contracts to offset some of the foreign currency exchange risk on our expected future cash flows and interest rate swaps to offset some of the interest rate risk on our expected future cash flows from certain borrowings. Our derivative instruments expose us to credit risk to the extent that our hedge counterparties may be unable to meet the terms of the applicable derivative instrument. We seek to mitigate such risks by limiting our counterparties to major financial institutions. In addition, we monitor the potential risk of loss with any one counterparty resulting from credit risk. Management does not expect material losses as a result of defaults by counterparties. We use derivative instruments to manage cash flow and not for speculative or trading purposes. Cash Flow Hedges For qualifying cash flow hedges, the effective and ineffective portion of the gain or loss on the change in fair value is initially reported as a component of accumulated other comprehensive income in partners’ capital and subsequently reclassified into earnings when the hedged exposure affects earnings. Prior to January 1, 2019 and the adoption of ASU 2017-12 (see Note 2, Significant Accounting Policies ), the ineffective portion of the gain or loss, if any, was reported in earnings in the current period. We considered our cash flow hedges to be highly effective at inception. Changes in fair value for derivative instruments not designated as hedging instruments are recognized in earnings. Foreign Currency Exchange Risk We are primarily exposed to fluctuations in foreign currency exchange rates related to off-take contracts that require future deliveries of wood pellets to be settled in British Pound Sterling (“GBP”) and Euro (“EUR”). We have entered and may continue to enter into foreign currency forward contracts, purchased option contracts or other instruments to partially manage this risk and, prior to August 2018, had designated certain of these instruments as cash flow hedges. In August 2018, due to market changes, increases in demand for wood pellets and requests from customers to accommodate the acceleration or deferral of contracted deliveries, we determined that it was no longer probable that the timing of the forecasted revenues associated with the hedged transactions would occur as originally scheduled. As a result, we discontinued hedge accounting for all designated foreign currency cash flow hedges and recognized the full amount of unrealized net gains included in accumulated other comprehensive income of $1.9 million to earnings. As of September 30, 2018, none of our foreign currency derivative instruments were designated as cash flow hedging instruments. In connection with the discontinuation of cash flow hedge accounting, we have recorded the on-going changes in the fair value of foreign currency derivatives as product sales or cost of sales depending on the nature of the item being hedged. Interest Rate Risk We are exposed to fluctuations in interest rates on borrowings under our senior secured revolving credit facility. We have entered into a pay-fixed, receive-variable interest rate swap that expires in April 2020 to hedge the interest rate risk associated with our variable rate borrowings under our senior secured revolving credit facility. The interest rate swap is designated and qualifies as a cash flow hedge. Derivative instruments are classified as Level 2 assets or liabilities based on inputs such as spot and forward benchmark interest rates (such as LIBOR) and foreign exchange rates. The fair value of derivative instruments as of September 30, 2019 and December 31, 2018 was as follows: Asset (Liability) Balance Sheet Classification September 30, 2019 December 31, 2018 Designated as hedging instruments: Interest rate swap Other current assets $ 122 $ 508 Other long-term assets — 118 Total derivatives designated as hedging instruments $ 122 $ 626 Not designated as hedging instruments: Foreign currency exchange forward contracts: Other current assets $ 1,647 $ 794 Other long-term assets 1,290 1,810 Accrued and other current liabilities — (68 ) Other long-term liabilities — (179 ) Foreign currency purchased option contracts: Other current assets 286 22 Other long-term assets 3,369 3,348 Total derivatives not designated as hedging instruments $ 6,592 $ 5,727 Net unrealized gains related to the change in fair market value of derivative instruments not designated as hedging instruments were $1.1 million and $1.4 million , respectively, during the three and nine months ended September 30, 2019 and are included in product sales. Realized gains related to derivatives settled were $1.6 million and $1.7 million , respectively, during the three and nine months ended September 30, 2019 , and are included in product sales. During the three and nine months ended September 30, 2018, we recorded $2.3 million and $5.4 million , respectively, of unrealized net gains on derivative instruments in product sales. Included in the unrealized net gains for both the three and nine months ended September 30, 2018 was $1.9 million related to the reclassification of unrealized net gains previously included in accumulated other comprehensive income as described above. Net gains related to the change in fair market value of derivative instruments not designated as hedging instruments were $0.4 million and $3.5 million , respectively during the three and nine months ended September 30, 2018 and are included in product sales. During the three months ended September 30, 2018, we received $4.3 million on realized gains related to derivatives settled during the period. The effects of instruments that were designated as cash flow hedges and the related changes in accumulated other comprehensive loss and the gains and losses recognized in earnings for the three months ended September 30, 2019 were as follows: Amount of Gain in Other Location of Amount of Interest rate swap $ 13 Interest expense $ 59 The effects of instruments that were designated as cash flow hedges and the related changes in accumulated other comprehensive loss and the gains and losses recognized in earnings for the nine months ended September 30, 2019 were as follows: Amount of Loss in Other Location of Amount of Interest rate swap $ (148 ) Interest expense $ 252 The effects of instruments that were designated as cash flow hedges and the related changes in accumulated other comprehensive loss and the gains and losses recognized in earnings for the three months ended September 30, 2018 were as follows: Amount of Gain Location of Amount of Location of (Loss) Gain Amount of Gain Foreign currency exchange forward contracts $ 1,907 Product sales $ — Product sales $ 2,418 Foreign currency exchange purchased option contracts 765 Product sales — Product sales (470 ) Interest rate swap 41 Interest expense — Interest expense 67 The effects of instruments that were designated as cash flow hedges and the related changes in accumulated other comprehensive loss and the gains and losses recognized in earnings for the nine months ended September 30, 2018 were as follows: Amount of Gain Location of Amount of Location of Gain Amount of Gain Foreign currency exchange forward contracts $ 4,532 Product sales $ — Product sales $ 2,413 Foreign currency exchange purchased option contracts 749 Product sales — Product sales (470 ) Interest rate swap 469 Interest expense — Interest expense 131 We enter into master netting arrangements, which are designed to permit net settlement of derivative transactions among the respective counterparties. If we had settled all transactions with our respective counterparties at September 30, 2019 , we would have received a net settlement termination payment of $6.7 million , which differs insignificantly from the recorded fair value of the derivatives. We present our derivative assets and liabilities at their gross fair values. The notional amounts of outstanding derivative instruments associated with outstanding or unsettled derivative instruments as of September 30, 2019 and December 31, 2018 were as follows: September 30, December 31, Foreign exchange forward contracts in GBP £ 38,140 £ 42,170 Foreign exchange purchased option contracts in GBP £ 43,415 £ 39,365 Foreign exchange forward contracts in EUR € 7,300 € 14,300 Foreign exchange purchased option contracts in EUR € 1,675 € 1,675 Interest rate swap $ 35,723 $ 39,829

Fair Value Measurements	Fair Value Measurements The amounts reported in the unaudited condensed consolidated balance sheets as cash and cash equivalents, accounts receivable, insurance receivables, related-party receivables, prepaid expenses and other current assets, accounts payable, related-party payables and accrued liabilities, and accrued and other current liabilities approximate fair value because of the short-term nature of these instruments. Long-term debt and finance lease obligations, including the current portion, are classified as Level 2 instruments. The fair value of our senior notes (see Note 12, Long-Term Debt and Finance Lease Obligations – Senior Notes Due 2021 ) was determined based on observable market prices in a less active market and was categorized as Level 2 in the fair value hierarchy. The fair value of other long-term debt and finance lease obligations classified as Level 2 was determined based on the usage of market prices not quoted on active markets and other observable market data. The fair value of long-term debt and finance lease obligations are based upon rates currently available for debt and finance lease obligations with similar terms and remaining maturities. The carrying amount and estimated fair value of long-term debt and finance lease obligations as of September 30, 2019 and December 31, 2018 were as follows: September 30, 2019 December 31, 2018 Carrying Amount Fair Value Carrying Amount Fair Value Senior notes $ 353,352 $ 362,227 $ 352,843 $ 359,943 Other long-term debt and finance lease obligations 194,727 194,727 79,812 79,812 Total long-term debt and finance lease obligations $ 548,079 $ 556,954 $ 432,655 $ 439,755

These increases to partners’ capital are comprised of expenses waived under the EVA MSA Fee Waiver and the First JV MSA Fee Waiver and reimbursement of construction cost overruns in excess of budgeted capital expenditures for the Hamlet plant. The net reduction in cost of goods sold is comprised of the cost of cover deficiency fee from the Hamlet Operator under the ISA not producing enough pellets at Hamlet, offset by the agreed-upon price due to the Hamlet Operator for the pellets from Hamlet that we have sold. Second EVA MSA Fee Waiver In June 2019, we entered into an additional agreement (the “Second EVA MSA Fee Waiver”) with Enviva Management pursuant to which we received a $5.0 million waiver of EVA MSA fees through September 30, 2019, as consideration for an assignment of two shipping contracts to our sponsor to rebalance our and our sponsor’s respective shipping obligations under existing off-take contracts. During the three and nine months ended September 30, 2019 , $2.3 million and $5.0 million , respectively, of EVA MSA fees expensed were waived and recorded as an increase to partners’ capital pursuant to the Second EVA MSA Fee Waiver. During the three and nine months ended September 30, 2018 , no EVA MSA fees were waived pursuant to the Second EVA MSA Fee Waiver. Wilmington Drop-Down - Deferred Consideration In October 2017, we acquired from the First JV all of the issued and outstanding limited liability company interests in Enviva Port of Wilmington, LLC (“Wilmington”), which owns the Wilmington terminal assets (the “Wilmington Drop-Down”), for total consideration of $130.0 million , subject to certain conditions. The Wilmington Drop-Down included the Wilmington terminal assets and a long-term terminal services agreement with our sponsor (the “Holdings TSA”) to handle throughput volumes sourced from Greenwood. The purchase price included $74.0 million of deferred consideration, which was paid in full in April 2019 and consisted of $24.3 million in cash, of which $22.8 million was distributed to the Hancock Member and the issuance of 1,691,627 common units, or approximately $49.7 million in common units, which were distributed to the Hancock Member. The $74.0 million of deferred consideration was reflected on the condensed consolidated balance sheets as of December 31, 2018 . Greenwood Contract In February 2018, we entered into a contract with Greenwood to purchase wood pellets produced by the Greenwood plant through March 2022 (the “Greenwood contract”) and we have a take-or-pay obligation with respect to 550,000 MTPY of wood pellets from July 2019 through March 2022. In July 2019, we entered into an amendment whereby the commencement of the take-or-pay obligation date was deferred from July 2019 to January 2020. During the three and nine months ended September 30, 2019 , we purchased $11.3 million and $35.5 million , respectively, of wood pellets and recorded a cost of cover deficiency fee from Greenwood of approximately $1.0 million and $4.3 million , respectively, from Greenwood as Greenwood was unable to satisfy certain commitments. Of the net $8.6 million and $29.5 million , respectively, $9.7 million and $33.8 million , respectively, is included in cost of goods sold and $1.5 million is included in finished goods inventory as of September 30, 2019 .

Holdings TSA The Wilmington Drop-Down included a long-term terminal services agreement with our sponsor (the “Holdings TSA”). Pursuant to the Holdings TSA, our sponsor agreed to deliver a minimum of 125,000 MT of wood pellets per quarter for receipt, storage, handling and loading services by the Wilmington terminal and pay a fixed fee on a per-ton basis for such terminal services. The Holdings TSA remains in effect until September 1, 2026. We did no t record any terminal services revenue from our sponsor during the three months ended September 30, 2018 . During the nine months ended September 30, 2018 , we recorded $0.8 million as terminal services revenue from our sponsor, which is included in other revenue. In February 2018, our sponsor amended and assigned the Holdings TSA to Greenwood. Deficiency payments are due to Wilmington if quarterly minimum throughput requirements are not met. During the three and nine months ended September 30, 2019 and 2018 , we recorded $0.5 million and $1.3 million , respectively, and $0.5 million and $2.0 million , respectively, of deficiency fees from Greenwood, which is included in other revenue. In September 2018, Hurricane Florence impacted the rail line on which wood pellets are typically transported from the Greenwood plant to the Wilmington terminal. As a result, Greenwood was unable to satisfy certain commitments under the Holdings TSA and the Greenwood contract and agreed to pay $1.8 million to us as deficiency fees in consideration of these commitments. Consideration of $0.5 million related to the Holdings TSA was included in other revenue and $1.3 million related to the Greenwood contract was included as a reduction of cost of goods sold. Biomass Option Agreement – Enviva Holdings, LP Enviva, LP purchased none and $1.7 million of wood pellets from the sponsor during the three and nine months ended September 30, 2018 , respectively, pursuant to a biomass option agreement. The wood pellet purchase amounts are included in cost of goods sold. The biomass option agreement terminated in accordance with its terms in March 2018. Enviva FiberCo, LLC We purchase raw materials from Enviva FiberCo, LLC (“FiberCo”), a wholly owned subsidiary of our sponsor. During the three and nine months ended September 30, 2019 , purchased raw materials, net of cost of cover deficiency fees from FiberCo, were immaterial and $0.6 million , respectively. During the three and nine months ended September 30, 2018 , we purchased raw materials of $1.8 million and $3.5 million , respectively, from FiberCo. No cost of cover deficiency fees from FiberCo were recognized during the three and nine months ended September 30, 2018 . Long-Term Incentive Plan Vesting As of September 30, 2019 , we had an insignificant amount included in related-party payables related to withholding tax amounts due to Enviva Management associated with the vesting of time-based phantom units under the Enviva Partners, LP Long-Term Incentive Plan (“LTIP”).

Partners' Capital Notes [Abstract]
Partners' Capital	Partners’ Capital Common Units - Issuance During March 2019, we issued 3,508,778 common units in a registered direct offering for net proceeds of approximately $97.0 million , net of $3.0 million of issuance costs. On April 1, 2019, as deferred consideration for the Wilmington Drop-Down, we issued 1,691,627 common units, or $49.7 million in common units, to the First JV, which common units were distributed to the Hancock Member. On April 2, 2019, in connection with the JV 1.0 Drop-Down, we issued 1,681,237 common units, or $50.0 million in common units, to the sponsor. Allocations of Net Income The Partnership’s partnership agreement contains provisions for the allocation of net income and loss to the unitholders of the Partnership and the General Partner. For purposes of maintaining partner capital accounts, the partnership agreement specifies that items of income and loss shall be allocated among the partners of the Partnership in accordance with their respective percentage ownership interest. Such allocations are made after giving effect, if any, to priority income allocations in an amount equal to incentive cash distributions, which are allocated 100% to the General Partner. Incentive Distribution Rights Incentive distribution rights (“IDRs”) represent the right to receive increasing percentages (from 15.0% to 50.0% ) of quarterly distributions from operating surplus after distributions in amounts exceeding specified target distribution levels have been achieved by the Partnership. Our general partner (“General Partner”) currently holds the IDRs, but may transfer these rights at any time. At-the-Market Offering Program Pursuant to an equity distribution agreement dated August 8, 2016, we may offer and sell common units from time to time through a group of managers, subject to the terms and conditions set forth in such agreement, of up to an aggregate sales amount of $100.0 million (the “ATM Program”). During the three and nine months ended September 30, 2019 , we did no t sell common units under the ATM Program. During the three months ended September 30, 2018 , we did not sell common units under the ATM Program. During the nine months ended September 30, 2018 , we sold 8,408 common units under the ATM Program for net proceeds of $0.2 million , net of an insignificant amount of commissions. Net proceeds from sales under the ATM Program were used for general partnership purposes. First JV The capital of the First JV is divided into two classifications: (1) Class A Units and (2) Class B Units, issued at a price of $1.00 per unit for each class. Class A Units - Noncontrolling Interests Class A Units were issued to the Hancock Member in exchange for capital contributions at a price of $1.00 for each Class A Unit. The Hancock Member had a total capital commitment of $235.2 million and, as of September 30, 2019 , the Hancock Member held 227.0 million Class A Units with a remaining capital commitment amount of $8.2 million . Class B Units - Controlling Interests Class B Units were issued to the Enviva Member in exchange for capital contributions at a price of $1.00 for each Class B Unit. The Enviva Member had a total capital commitment of $232.2 million and, as of September 30, 2019 , the Enviva Member held 224.0 million Class B Units with a remaining commitment amount of $8.2 million . Pursuant to the limited liability company agreement of the First JV (the “First JV LLCA”), we are the managing member of the First JV and have the authority to manage the business and affairs of the First JV and take actions on its behalf, including adopting annual budgets, entering into agreements, effecting asset sales or biomass purchase agreements, making capital calls, incurring debt and taking other actions, subject to consent of the Hancock Member in certain circumstances. The First JV LLCA also sets forth the capital commitments and limitations thereon from each of the members, and provides for the allocation of sale proceeds and distributions among the holders of outstanding Class A Units and Class B Units. We included all accounts of the First JV in our consolidated results as of April 2, 2019 as the Class B Units represent a controlling interest in the First JV. Distribution Rights Distributions to the Hancock Member, and to the Enviva Member, are made in the reasonable discretion of the Enviva Member and are governed by the waterfall provisions of the First JV LLCA, which provides that distributions, after repayment of the First JV Revolver borrowings, are to be made as follows: • First: To the members in proportion to their relative unreturned capital contributions, then to the members in proportion to their relative unpaid preference amount. • Thereafter: 25% to the Hancock Member and 75% to the Enviva Member. Prior to the JV 1.0 Drop-Down, at the discretion of the Enviva Member, the Hancock Member had received all of its capital contributions and substantially all of its preference amount. Given that and the historical net losses of the First JV having been previously allocated to the Enviva Member and the Hancock Member in proportion to their unreturned capital contributions, the balance of the First JV members’ capital attributable to the Hancock Member had become negative as of the JV 1.0 Drop-Down. Additionally, given that and the extent to which the Enviva Member has yet to receive repayment of its revolver borrowings, capital contributions and preference amount as of September 30, 2019 , none of the net loss of the First JV has been allocated to the Hancock Member subsequent to the date of the JV 1.0 Drop-Down. Thus, no change has been recognized to the acquired negative noncontrolling interest balance attributable to the Hancock Member.

As of September 30, 2019 , an insignificant amount is included in related-party payables to Enviva Management to satisfy tax-withholding requirements associated with time-based phantom awards that vested under the LTIP during the nine months ended September 30, 2019 . During the nine months ended September 30, 2018 , we paid $2.3 million to the General Partner, which acquired common units from a wholly owned subsidiary of our sponsor for delivery to the recipients under the LTIP. We also paid $1.7 million during the nine months ended September 30, 2018 to Enviva Management to satisfy the tax-withholding requirements associated with such common units under the MSAs. The unrecognized estimated compensation cost relating to outstanding Affiliate Grants at September 30, 2019 was $14.2 million , which will be recognized over the remaining vesting period.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes Our operations are organized as limited partnerships and entities that are disregarded entities for federal and state income tax purposes. As a result, we are not subject to U.S. federal and most state income taxes. The unitholders of the Partnership are liable for these income taxes on their share of our taxable income. Some states impose franchise and capital taxes on the Partnership. Such taxes are not material to the condensed consolidated financial statements and have been included in other income (expense) as incurred. As of September 30, 2019 , the only periods subject to examination for federal and state income tax returns are 2015 through 2018 . We believe our income tax filing positions, including our status as a pass-through entity, would be sustained on audit and do not anticipate any adjustments that would result in a material change to our unaudited condensed consolidated balance sheet. Therefore, no reserves for uncertain tax positions or interest and penalties have been recorded. For the three and nine months ended September 30, 2019 and 2018 , no provision for federal or state income taxes has been recorded in the condensed consolidated financial statements.

Net Income (Loss) per Limited P

Earnings Per Share [Abstract]
Net Income (Loss) per Limited Partner Unit	Net Income (Loss) per Limited Partner Unit Net income (loss) per unit applicable to limited partners is computed by dividing limited partners’ interest in net income (loss), after deducting any incentive distributions, by the weighted-average number of outstanding common units. Our net income (loss) is allocated to the limited partners in accordance with their respective ownership percentages, after giving effect to priority income allocations for incentive distributions, if any, to the holder of the IDRs, which are declared and paid following the close of each quarter. Earnings in excess of distributions are allocated to the limited partners based on their respective ownership interests. Payments made to our unitholders are determined in relation to actual distributions declared and are not based on the net income (loss) allocations used in the calculation of earnings per unit. On May 30, 2018, the requirements under our partnership agreement for the conversion of all of our subordinated units into common units were satisfied and the subordination period for such subordinated units ended. As a result, all of our 11,905,138 outstanding subordinated units converted into common units on a one -for-one basis. The conversion did not impact the amount of the cash distribution paid or the total number of our outstanding units representing limited partner interests. Our net income (loss) was allocated to the General Partner and the limited partners, including the holders of the subordinated units and IDR holders, in accordance with our partnership agreement. In addition to the common units, we have also identified the IDRs and phantom units as participating securities and use the two-class method when calculating the net income (loss) per unit applicable to limited partners, which is based on the weighted-average number of common units and subordinated units outstanding during the period. Diluted net income per unit includes the effects of potentially dilutive time-based and performance-based phantom units on our common units. Basic and diluted earnings per unit previously applicable to subordinated limited partner units were the same because there are no potentially dilutive subordinated units outstanding. The following computation of net income (loss) per limited partner unit is as follows for the three and nine months ended September 30, 2019 and 2018 : Three Months Ended Common General Weighted-average common units outstanding—basic 33,457 — Effect of nonvested phantom units — — Weighted-average common units outstanding—diluted 33,457 — Three Months Ended September 30, 2019 Common Units General Partner Total Distributions declared $ 22,416 $ 3,107 $ 25,523 Earnings less than distributions (17,275 ) — (17,275 ) Net income available to partners $ 5,141 $ 3,107 $ 8,248 Weighted-average units outstanding—basic and diluted 33,457 Net income per limited partner unit—basic and diluted $ 0.15 Nine Months Ended Common General Weighted-average common units outstanding—basic 31,230 — Effect of nonvested phantom units — — Weighted-average common units outstanding—diluted 31,230 — Nine Months Ended September 30, 2019 Common General Total Distributions declared $ 66,077 $ 8,150 $ 74,227 Earnings less than distributions (79,925 ) — (79,925 ) Net (loss) income available to partners $ (13,848 ) $ 8,150 $ (5,698 ) Weighted-average units outstanding—basic and diluted 31,230 Net loss per limited partner unit—basic and diluted $ (0.44 ) Three Months Ended September 30, 2018 Common Subordinated General Weighted-average common units outstanding—basic 26,477 — — Effect of nonvested phantom units 1,001 — — Weighted-average common units outstanding—diluted 27,478 — — Three Months Ended September 30, 2018 Common Units General Partner Total Distributions declared $ 16,814 $ 1,532 $ 18,346 Earnings less than distributions (4,990 ) — (4,990 ) Net income available to partners $ 11,824 $ 1,532 $ 13,356 Weighted-average units outstanding—basic 26,477 Weighted-average units outstanding—diluted 27,478 Net income per limited partner unit—basic $ 0.45 Net income per limited partner unit—diluted $ 0.43 Nine Months Ended September 30, 2018 Common Subordinated General Weighted-average common units outstanding—basic 19,866 6,541 — Effect of nonvested phantom units — — — Weighted-average common units outstanding—diluted 19,866 6,541 — Nine Months Ended September 30, 2018 Common Subordinated General Total Distributions declared $ 37,618 $ 12,386 $ 4,197 $ 54,201 Earnings less than distributions (42,607 ) (14,029 ) — (56,636 ) Net (loss) income available to partners $ (4,989 ) $ (1,643 ) $ 4,197 $ (2,435 ) Weighted-average units outstanding—basic and diluted 19,866 6,541 Net loss per limited partner unit—basic and diluted $ (0.25 ) $ (0.25 ) Cash Distributions to Unitholders Distributions that have been paid or declared related to the reporting period are considered in the determination of earnings per unit.

Any unpaid cumulative distributions are allocated to the appropriate class of equity. We determine the amount of cash available for distribution for each quarter in accordance with our partnership agreement. The amount to be distributed to common unitholders and IDR holders is based on the distribution waterfall set forth in our partnership agreement. Net earnings for the quarter are allocated to each class of partnership interest based on the distributions to be made. On May 30, 2018, the subordination period ended in accordance with our partnership agreement and the subordinated units were converted into common units on a one -for-one basis.

Accounting Policies [Abstract]
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make judgments, estimates and assumptions that affect the amounts reported in our unaudited financial statements and accompanying notes. Actual results could differ materially from those estimates.
Accounting Standards Adopted and Recently Issued not yet Adopted	Accounting Standards Adopted Leases ASU 2016-02 established a right-of-use (“ROU”) model that requires lessees to recognize a ROU asset and corresponding lease liability on the balance sheet for all leases with a term of longer than 12 months and classify leases as operating or finance. Operating lease expense is recorded in a single financial statement line item on a straight-line basis over the lease term. Amortization of the ROU asset is the calculated difference between straight-line lease expense and the accretion of interest on the lease liability each period. We adopted ASU 2016-02 on and as of January 1, 2019 using the modified retrospective transition method, which we applied to all leases existing at the date of initial application of the ASU. We elected to use the effective date as the date of initial application, as opposed to the beginning of the earliest comparative period presented in the financial statements; consequently, financial information and disclosures are not presented under the new standard for periods prior to January 1, 2019. We elected the package of three practical expedients under the transition guidance within the new standard, which permitted us to reassess our prior conclusions under the previous guidance concerning lease identification, lease classification and initial direct leasing costs. We elected the practical expedient to not evaluate existing or expired land easements that were not accounted for as leases under previous guidance. We did not, however, elect the separate practical expedient pertaining to the use of hindsight in determining the lease term for existing leases. We have a significant contract containing both lease and nonlease components, which are accounted for separately. As this contract has fixed payments, the allocation of lease and nonlease components is based on relative standalone price. The adoption of the new standard as of January 1, 2019 resulted in the recognition of operating lease ROU assets of $27.4 million , net of $2.1 million of deferred rent liabilities existing as of December 31, 2018, and operating lease liabilities of $29.5 million for operating leases related to real estate, machinery and equipment and other operating leases with terms of longer than 12 months. The amounts recognized as of January 1, 2019 were based on the present value of the remaining minimum rental payments under previous leasing standards for existing operating leases. The classification of a lease affects the pattern and classification of expense recognition in the income statement, which is unchanged from under the previous accounting method. The adoption of the new standard did not change our accounting for finance leases (which were described as “capital leases” under the previous standard) or impact our results of operations and cash flows. See Note 9, Leases . Derivative Instruments We adopted ASU 2017-12 on and as of January 1, 2019 using the modified retrospective method, which requires the recognition of the cumulative effect of the change on the opening balance of each affected component of equity in the statement of changes in partner’s capital as of the date of adoption of the new standard. Upon adoption of ASU 2017-12, we no longer measure and recognize ineffectiveness related to designated and qualifying cash flow hedges in earnings; as a result, any ineffectiveness is included in accumulated other comprehensive income. On January 1, 2019, we recorded a nominal cumulative effect adjustment to accumulated other comprehensive income and common units in partners’ capital. See Note 10, Derivatives. Recently Issued Accounting Standards not yet Adopted Currently, there are no recently issued accounting standards not yet adopted by us that we expect to be reasonably likely to materially impact the financial position, results of operations or cash flows of the Partnership.
