Nature of the business [Abstract]
Nature of the business	Note 1. - Nature of the business Atlantica Yield plc (“Atlantica” or the “Company”) was incorporated in England and Wales as a private limited company on December 17, 2013 under the name Abengoa Yield Limited. On March 19, 2014, the Company was re-registered as a public limited company, under the name Abengoa Yield plc. On May 13, 2016, the change of the Company´s registered name to Atlantica Yield plc was filed with the Registrar of Companies in the United Kingdom. Atlantica is a sustainable total return infrastructure company that owns, manages and acquires renewable energy, efficient natural gas, electric transmission lines and water assets focused on North America (the United States, Mexico and Canada), South America (Peru, Chile and Uruguay) and EMEA (Spain, Algeria and South Africa). Atlantica’s shares began trading on the NASDAQ Global Select Market under the symbol “ABY” on June 13, 2014. The symbol changed to “AY” on November 11, 2017. Algonquin Power & Utilities (“Algonquin”) is the largest shareholder of the Company and currently owns a 44.2% stake in Atlantica. Algonquin’s shareholding in Atlantica may be increased up to a 48.5% without any change in corporate governance. Algonquin’s voting rights and rights to appoint directors are limited to a 41.5% and the additional 7% would vote replicating non-Algonquin’s shareholders vote. Algonquin does not consolidate the Company in its consolidated financial statements. During the year 2019, the Company completed the following acquisitions: - In January 2019, the Company entered into an agreement with Abengoa under the Abengoa ROFO Agreement for the acquisition of Befesa Agua Tenes, a holding company which owns a 51% stake in Tenes, a water desalination plant in Algeria. The price agreed for the equity value was $24.5 million, of which $19.9 million were paid in January 2019 as an advanced payment. Closing of the acquisition was subject to conditions precedent, including approval by the Algerian administration. The conditions precedent set forth in the share purchase agreement were not fulfilled as of September 30, 2019. Therefore, in accordance with the terms of the share purchase agreement the advanced payment has been converted into a secured loan to be reimbursed by Befesa Agua Tenes, together with 12% per annum interest, through a full cash-sweep of all the dividends generated to be received from the asset. These dividends would be guaranteed by a right of usufruct over the economic rights and certain political rights and a pledge over the shares of Befesa Agua Tenes, granted by Abengoa to the Company. The share purchase agreement requires that the repayment occurs no later than September 30, 2031. In October 2019 the Company received a first payment of $7.8 million through the cash sweep mechanism. - On April 15, 2019, the Company entered into an agreement to acquire a 30% stake in Monterrey, a 142 MW gas-fired engine facility (“Monterrey”). The acquisition was closed on August 2, 2019, after conditions precedent were fulfilled, and the Company paid $42 million for the total investment. - On May 9, 2019, the Company entered into a partnership agreement with Algonquin, investing $4.9 million in the equity of a wind farm, Amherst Island, with a 75 MW installed capacity, owned and operated by Algonquin in Canada. - - - The following table provides an overview of the main concessional assets the Company owned or had an interest in as of March 31, 2020: Assets Type Ownership Location Currency (8) Capacity (Gross) Counterparty Credit Ratings (9) COD* Contract Years Left (13) Solana Renewable (Solar) 100% Class B (1) Arizona (USA) USD 280 MW A-/A2/A- 2013 24 Mojave Renewable (Solar) 100% California (USA) USD 280 MW NR/WR/WD 2014 20 Solaben 2 & 3 Renewable (Solar) 70% (2) Spain Euro 2x50 MW A/Baa1/A- 2012 18/17 Solacor 1 & 2 Renewable (Solar) 87% (3) Spain Euro 2x50 MW A/Baa1/A- 2012 17/17 PS10/PS20 Renewable (Solar) 100% Spain Euro 31 MW A/Baa1/A- 2007& 2009 12/14 Helioenergy 1 & 2 Renewable (Solar) 100% Spain Euro 2x50 MW A/Baa1/A- 2011 17/17 Helios 1 & 2 Renewable (Solar) 100% Spain Euro 2x50 MW A/Baa1/A- 2012 18/18 Solnova 1, 3 & 4 Renewable (Solar) 100% Spain Euro 3x50 MW A/Baa1/A- 2010 15/15/16 Solaben 1 & 6 Renewable (Solar) 100% Spain Euro 2x50 MW A/Baa1/A- 2013 19/19 Kaxu Renewable (Solar) 51% (4) South Africa Rand 100 MW BB/Ba1/ BB (10) 2015 15 Palmatir Renewable (Wind) 100% Uruguay USD 50 MW BBB/Baa2/BBB- (11) 2014 14 Cadonal Renewable (Wind) 100% Uruguay USD 50 MW BBB/Baa2/BBB- (11) 2014 15 ACT Efficient natural gas 100% Mexico USD 300 MW BBB/ Ba2/ BB- 2013 13 Monterrey Efficient natural gas 30% Mexico USD 142 MW Not rated 2018 19 ATN (12) Transmission line 100% Peru USD 379 miles BBB+/A3/BBB+ 2011 21 ATS Transmission line 100% Peru USD 569 miles BBB+/A3/BBB+ 2014 24 ATN 2 Transmission line 100% Peru USD 81 miles Not rated 2015 13 Quadra 1 Transmission line 100% Chile USD 49 miles Not rated 2014 15 Quadra 2 Transmission line 100% Chile USD 32 miles Not rated 2014 15 Palmucho Transmission line 100% Chile USD 6 miles BBB+/Baa1/ A- 2007 18 Chile TL3 Transmission line 100% Chile USD 50 miles A+/A1/A 1993 Regulated Skikda Water 34.2%(5) Algeria USD 3.5 M ft3/day Not rated 2009 14 Honaine Water 25.5%(6) Algeria USD 7 M ft3/ day Not rated 2012 18 Seville PV Renewable (Solar) 80%(7) Spain Euro 1 MW A/Baa1/A- 2006 16 Melowind Renewable (Wind) 100% Uruguay USD 50MW BBB/Baa2/BBB- 2015 16 Mini-Hydro Renewable (Hydraulic) 100% Peru USD 4 MW BBB+/A3/BBB+ 2012 13 (1) On September 30, 2013, Liberty Interactive Corporation agreed to invest $300 million in Class A shares of ASO Holdings Company LLC, the holding company of Solana, in exchange for a share of the dividends and the taxable losses generated by Solana (Note 16).

The project financing arrangement of Kaxu contains cross-default provisions related to Abengoa such that debt defaults by Abengoa, subject to certain threshold amounts and/or a restructuring process, could trigger a default under the Kaxu project financing arrangement. In March 2017, Atlantica obtained a waiver in its Kaxu project financing arrangement which waives any potential cross-defaults with Abengoa up to that date, but it does not cover potential future cross-default events. As of March 31, 2020, the Company is not aware of the existence of any cross-default events with Abengoa. Outbreak of the COVID-19 The outbreak of the COVID-19 coronavirus disease (“COVID-19”) has been declared a pandemic by the World Health Organization and continues to spread in some of the key markets of the Company. The COVID-19 virus continues to evolve rapidly, and its ultimate impact is uncertain and subject to change. Governmental authorities have imposed or recommended measures or responsive actions, including quarantines of certain geographic areas and travel restrictions. Main risks and uncertainties identified by the Company, which may result in a material adverse effect on its business, financial condition, results of operations and cash flows, are: - The COVID-19 may affect the operation and maintenance employees of the Company as well as suppliers of operation and maintenance. Furthermore, COVID-19 has caused travel restrictions and significant disruptions to global supply chains. A prolonged disruption could limit the availability of certain parts required to operate the facilities of the Company and adversely impact the ability of its operation and maintenance suppliers. If the Company were to experience a shortage of or inability to acquire critical spare parts, it could incur significant delays in returning facilities to full operation. - Slowdown of broad sectors of the economy, a general reduction in demand, including demand for commodities and a negative impact on prices of commodities, including electricity, oil and gas. The global outbreak has also caused significant disruption and volatility in the global financial markets, including the market price of the shares of the Company. Debt and equity markets have also been affected and there have been weeks with a very low number of new debt and equity issuance transactions. Interest rates for new issuances and spreads with respect to treasury yields have increased significantly. Although all the revenues of the Company are contracted or regulated, clients may be affected by a reduced demand, lower commodity prices and the turmoil in the credit markets. A reduced demand and low prices persisting over time could cause delays in collections, a deterioration in the financial situation of the clients of the Company or their bankruptcy. Measures taken by the Company so far have been to reinforce safety measures in all its assets while it continues to provide a reliable service to its clients. For example, the Company has implemented the use of additional protection equipment, reinforced access control to its plants, reduced contact between employees, changed shifts and taken additional measures to increase safety measures for its employees and operation and maintenance suppliers’ employees working at its assets. Furthermore, the Company has adopted additional precautionary measures intended to mitigate potential risks to its employees, including temporarily requiring all employees to work remotely where their work can be done from home, and suspending all non-essential travel which could negatively affect the business of the Company. The Company has also reinforced its physical and cyber-security measures to ensure that its systems remain functional in order to both serve operational needs with a remote workforce and keep them running to ensure uninterrupted service to its customers. The COVID-19 did not have any material impact on these condensed interim financial statements.

Basis of preparation [Abstract]
Basis of preparation	Note 2. - Basis of preparation The accompanying consolidated condensed interim financial statements represent the consolidated results of the Company and its subsidiaries. The company´s annual consolidated financial statements as of December 31, 2019, were approved by the Board of Directors on February 26, 2020. These consolidated condensed interim financial statements are presented in accordance with International Accounting Standards (“IAS”) 34, “Interim Financial Reporting”. In accordance with IAS 34, interim financial information is prepared solely in order to update the most recent annual consolidated financial statements prepared by the Company, placing emphasis on new activities, occurrences and circumstances that have taken place during the three-month period ended March 31, 2020, and not duplicating the information previously published in the annual consolidated financial statements for the year ended December 31, 2019. Therefore, the consolidated condensed interim financial statements do not include all the information that would be required in a complete set of consolidated financial statements prepared in accordance with the IFRS-IASB (“International Financial Reporting Standards-International Accounting Standards Board”). In view of the above, for an adequate understanding of the information, these consolidated condensed interim financial statements must be read together with Atlantica’s consolidated financial statements for the year ended December 31, 2019 included in the 2019 20-F. In determining the information to be disclosed in the notes to the consolidated condensed interim financial statements, Atlantica, in accordance with IAS 34, has taken into account its materiality in relation to the consolidated condensed interim financial statements. The consolidated condensed interim financial statements are presented in U.S. dollars, which is the Company’s functional and presentation currency. Amounts included in these consolidated condensed interim financial statements are all expressed in thousands of U.S. dollars, unless otherwise indicated. These consolidated condensed interim financial statements were approved by the Board of Directors of the Company on May 6, 2020. Application of new accounting standards a) Standards, interpretations and amendments effective from January 1, 2020 under IFRS-IASB, applied by the Company in the preparation of these condensed interim financial statements: - IFRS 3 (Amendment). Definition of Business. This amendment is mandatory for annual periods beginning on or after January 1, 2020 under IFRS-IASB, earlier application is permitted. - IAS 1 and IAS 8 (Amendment). Definition of Material. This amendment is mandatory for annual periods beginning on or after January 1, 2020 under IFRS-IASB, earlier application is permitted. - IFRS 7 and IFRS 9. Amendments regarding pre-replacement issues in the context of the IBOR reform. These amendments are mandatory for annual periods beginning on or after January 1, 2020 under IFRS-IASB. - Amendments to References to the Conceptual Frameworks in IFRS Standards. This Standard is applicable for annual periods beginning on or after January 1, 2020 under IFRS-IASB. The applications of these amendments have not had any material impact on these condensed interim financial statements. b) Standards, interpretations and amendments published by the IASB that will be effective for periods beginning on or after January 1, 2021: - IFRS 17 ‘Insurance Contracts’. This Standard is applicable for annual periods beginning on or after January 1, 2021 under IFRS-IASB, earlier application is permitted. - IAS 1 (Amendment). Classification of liabilities. This amendment is mandatory for annual periods beginning on or after January 1, 2022 under IFRS-IASB. The Company does not anticipate any significant impact on the consolidated condensed financial statements derived from the application of the new standards and amendments that will be effective for annual periods beginning on or after January 1, 2021, although it is currently still in the process of evaluating such application. Use of estimates Some of the accounting policies applied require the application of significant judgment by management to select the appropriate assumptions to determine these estimates. These assumptions and estimates are based on the Company´s historical experience, advice from experienced consultants, forecasts and other circumstances and expectations as of the close of the financial period. The assessment is considered in relation to the global economic situation of the industries and regions where the Company operates, taking into account future development of our businesses. By their nature, these judgments are subject to an inherent degree of uncertainty; therefore, actual results could materially differ from the estimates and assumptions used. In such cases, the carrying values of assets and liabilities are adjusted. The most critical accounting policies, which reflect significant management estimates and judgment to determine amounts in these consolidated condensed interim financial statements, are as follows: • Contracted concessional agreements. • Impairment of intangible assets and property, plant and equipment. • Assessment of control. • Derivative financial instruments and fair value estimates. • Income taxes and recoverable amount of deferred tax assets. As of the date of preparation of these consolidated condensed interim financial statements, no relevant changes in the estimates made are anticipated and, therefore, no significant changes in the value of the assets and liabilities recognized at March 31, 2020 are expected. Although these estimates and assumptions are being made using all available facts and circumstances, it is possible that future events may require management to amend such estimates and assumptions in future periods. Changes in accounting estimates are recognized prospectively, in accordance with IAS 8, in the consolidated income statement of the period in which the change occurs.

Risk is managed by the Company’s Risk Finance and Compliance Departments, which are responsible for identifying and evaluating financial risks, quantifying them by project, region and company, in accordance with mandatory internal management rules. Written internal policies exist for global risk management, as well as for specific areas of risk. In addition, there are official written management regulations regarding key controls and control procedures for each company and the implementation of these controls is monitored through internal audit procedures. These consolidated condensed interim financial statements do not include all financial risk management information and disclosures required for annual financial statements and should be read together with the information included in Note 3 to Atlantica’s annual consolidated financial statements as of December 31, 2019.

Financial information by segment [Abstract]
Financial information by segment	Note 4. - Financial information by segment Atlantica’s segment structure reflects how management currently makes financial decisions and allocates resources. Its operating segments are based on the following geographies where the contracted concessional assets are located: • North America • South America • EMEA Based on the type of business, as of March 31, 2020, the Company had the following business sectors: Renewable energy: Efficient natural gas: Electric transmission lines Water: Atlantica’s Chief Operating Decision Maker (CODM) assesses the performance and assignment of resources according to the identified operating segments. The CODM considers the revenues as a measure of the business activity and the Adjusted EBITDA as a measure of the performance of each segment. Adjusted EBITDA is calculated as profit/(loss) for the period attributable to the parent company, after adding back loss/(profit) attributable to non-controlling interests from continued operations, income tax, share of profit/(loss) of associates carried under the equity method, finance expense net, depreciation, amortization and impairment charges of entities included in these consolidated condensed interim financial statements. In order to assess performance of the business, the CODM receives reports of each reportable segment using revenues and Adjusted EBITDA. Net interest expense evolution is assessed on a consolidated basis. Financial expense and amortization are not taken into consideration by the CODM for the allocation of resources. In the three-month period ended March 31, 2020, Atlantica had two customers with revenues representing more than 10% of the total revenues, one in the renewable energy and one in the efficient natural gas business sectors. In the three-month period ended March 31, 2019, Atlantica had three customers with revenues representing more than 10% of the total revenues, two in the renewable energy and one in the efficient natural gas business sectors. a) The following tables show Revenues and Adjusted EBITDA by operating segments and business sectors for the three-month periods ended March 31, 2020 and 2019: Revenue Adjusted EBITDA For the three-month period ended March 31, For the three-month period ended March 31, ($ in thousands) Geography 2020 2019 2020 2019 North America 59,283 60,441 51,176 50,870 South America 35,654 33,493 28,422 28,212 EMEA 115,466 127,518 82,811 100,007 Total 210,403 221,452 162,409 179,089 Revenue Adjusted EBITDA For the three-month period ended March 31, For the three-month period ended March 31, ($ in thousands) Business sector 2020 2019 2020 2019 Renewable energy 150,793 156,817 113,491 123,484 Efficient natural gas 26,403 34,009 23,540 30,476 Electric transmission lines 26,608 24,867 21,538 21,650 Water 6,599 5,759 3,840 3,479 Total 210,403 221,452 162,409 179,089 The reconciliation of segment Adjusted EBITDA with the profit/(loss) attributable to the Company is as follows: For the three-month period ended March 31, ($ in thousands) 2020 2019 Profit/(Loss) attributable to the Company $ (40,511 ) (8,957 ) (Loss)/Profit attributable to non-controlling interests 2,246 5,267 Income tax (10,147 ) 9,577 Share of (profits)/losses of associates 668 (1,823 ) Financial expense, net 100,534 99,289 Depreciation, amortization, and impairment charges 109,619 75,736 Total segment Adjusted EBITDA $ 162,409 179,089 b) The assets and liabilities by operating segments (and business sector) as of March 31, 2020 and December 31, 2019 are as follows: Assets and liabilities by geography as of March 31, 2020: North America South America EMEA Balance as of March 31, 2020 ($ in thousands) Assets allocated Contracted concessional assets 3,238,914 1,170,544 3,497,872 7,907,329 Investments carried under the equity method 79,526 -

Changes in the scope of the consolidated condensed interim financial statements [Abstract]
Changes in the scope of the consolidated condensed interim financial statements	Note 5. - Changes in the scope of the consolidated condensed interim financial statements For the three-month period ended March 31, 2020 There is no change in the scope of the consolidated condensed interim financial statement in the three-month period ended March 31, 2020. For the year ended December 31, 2019 On May 24, 2019, Atlantica and Algonquin formed Atlantica Yield Energy Solutions Canada Inc. (“AYES Canada”), a vehicle to channel co-investment opportunities in which Atlantica holds the majority of voting rights. The first investment was in Amherst Island, a 75 MW wind plant in Canada owned by the project company Windlectric, Inc. (“Windlectric”). Atlantica invested $4.9 million and Algonquin invested $92.3 million, both through AYES Canada, which in turn invested those funds in Amherst Island Partnership (“AIP”), the holding company of Windlectric. Atlantica accounts for the investment in AIP and ultimately Windlectric under the equity method as per IAS 28, Investments in Associates and Joint Ventures. Since Atlantica has control over AYES Canada under IFRS 10 “Consolidated Financial Statements”, its consolidated financial statements initially showed a total investment in the Amherst Island project of $97.2 million, accounted for as “Investments carried under the equity method” (Note 7) and Algonquin’s portion of that investment of $92.3 million as “Non-controlling interest”. On August 2, 2019, the Company closed the acquisition of a 30% stake in Monterrey, a 142 MW gas-fired engine facility with batteries. The total investment amounted to $42 million, out of which $17 million is an equity investment, and the rest is a shareholder loan classified as financial investments in these consolidated condensed interim financial statements. The acquisition has been accounted for in the consolidated accounts of Atlantica, in accordance with IAS 28, Investments in Associates. On August 2, 2019, the Company closed the acquisition of a 100% stake in ASI Operations LLC (“ASI Ops”), the company that performs the operation and maintenance services for the Solana and Mojave plants. The total equity investment amounted to $6 million. The acquisition has been accounted for in the consolidated financial statements of Atlantica, in accordance with IFRS 3, Business Combinations. On October 22, 2019, the Company closed the acquisition of ATN Expansion 2 from Enel Green Power Perú, for a total equity investment of $20 million, controlling the asset from this date. Transfer of the concession agreement is pending authorization from the Ministry of Energy in Peru. If this authorization were not to be obtained within an eight-month period from the acquisition date, the transaction would be reversed with no penalties to Atlantica. Enel Green Power Perú issued a bank guarantee to address this potential repayment obligation to Atlantica. The purchase has been accounted for in the consolidated accounts of Atlantica, in accordance with IFRS 3, Business Combinations. Impact of changes in the scope in the consolidated financial statements The amount of assets and liabilities integrated at the effective acquisition date for the aggregated change in scope is shown in the following table: Asset Acquisition for the year ended December 31, 2019 Concessional assets 28,738 Investments carried under the equity method 113,897 Other non-current assets 25,342 Current assets 1,503 Deferred tax liabilities (2,539 ) Other current and non-current liabilities (1,512 ) Non-controlling interests (92,303 ) Asset acquisition - purchase price (73,126 ) Net result of the asset acquisition -

Concessional assets recorded in accordance with IFRIC 12 are either intangible or financial assets. As of March 31, 2020, contracted concessional financial assets amount to $781,136 thousand ($819,146 thousand as of December 31, 2019). The decrease in the contracted concessional assets cost is primarily due to the lower value of assets denominated in Euro and South African Rand since the exchange rate of the Euro and South African Rand decreased against the U.S. dollar since December 31, 2019. No losses from impairment of contracted concessional assets, excluding any change in the provision for expected credit losses under IFRS 9, Financial instruments, were recorded during the three-month periods ended March 31, 2020 and 2019. The impairment provision based on the expected credit losses on contracted concessional financial assets increased by $30 million in the three-month period ended March 31, 2020 (reversal of $4 million in the three-month period ended March 31, 2019), primarily in ACT Other matters Abengoa maintains a number of obligations under O&M and other contracts, as well as indemnities covering certain potential risks. Additionally, Abengoa represented that further to the accession to the restructuring agreement, Atlantica would not be a guarantor of any obligation of Abengoa with respect to third parties and agreed to indemnify the Company for any penalty claimed by third parties resulting from any breach in such representations. The Company has contingent assets, which have not been recognized as of March 31, 2020, related to the obligations of Abengoa referred above, which results and amounts will depend on the occurrence of uncertain future events.

All are classified as non-current assets or non-current liabilities, as they hedge long-term financing agreements. Additionally, the Company owns currency options with leading international financial institutions, which guarantee minimum Euro-U.S. dollar exchange rates. The strategy of the Company is to hedge the exchange rate for the distributions from its Spanish assets after deducting euro-denominated interest payments and euro-denominated general and administrative expenses. Through currency options, the strategy of the Company is to hedge 100% of its euro-denominated net exposure for the next 12 months and 75% of its euro denominated net exposure for the following 12 months, on a rolling basis. Hedge accounting is not applied to these options. The net amount of the fair value of interest rate derivatives designated as cash flow hedges transferred to the consolidated condensed income statement is a loss of $14.5 million for the three-month period ended March 31, 2020 (loss of $14.2 million in the three-month period ended March 31, 2019) The after-tax results accumulated in equity in connection with derivatives designated as cash flow hedges as of March 31, 2020 and December 31, 2019 amount to a profit of $43.9 million and $73.8 million, respectively (included under the caption “Other reserves”).

Project debt [Abstract]
Project debt	Note 15. - Project debt The main purpose of the Company is the long-term ownership and management of contracted concessional assets, such as renewable energy, efficient natural gas, electric transmission line and water assets, which are financed through project debt. This note shows the project debt linked to the contracted concessional assets included in Note 6 of these consolidated condensed interim financial statements. Project debt is generally used to finance contracted assets, exclusively using as guarantee the assets and cash flows of the company or group of companies carrying out the activities financed. In most of the cases, the assets and/or contracts are set up as guarantee to ensure the repayment of the related financing. In addition, the cash of the Company´s projects includes funds held to satisfy the customary requirements of certain non-recourse debt agreements and other restricted cash for an amount of $332 million as of March 31, 2020 ($339 million as of December 31, 2019). Compared with corporate debt, project debt has certain key advantages, including a greater leverage and a clearly defined risk profile. The breakdown of project debt for both non-current and current liabilities as of March 31, 2020 and December 31, 2019 is as follows: Balance as of March 31, Balance as of December 31, 2020 2019 ($ in thousands) Non-current 3,953,432 4,069,909 Current 823,760 782,439 Total Project debt 4,777,192 4,852,348 The decrease in total project debt as of March 31, 2020 is primarily due to the lower value of debt denominated in Euro and South African Rand given the weakened exchange rate of the Euro and South African Rand against the U.S. dollar since December 31, 2019.

The amount recorded in Grants as a liability is progressively recorded as other income over the useful life of the asset. The remaining balance of the “Grants” account corresponds to loans with interest rates below market rates for Solana and Mojave for a total amount of $372 million ($379 million as of December 31, 2019). Loans with the Federal Financing Bank guaranteed by the Department of Energy for these projects bear interest at a rate below market rates for these types of projects and terms. The difference between proceeds received from these loans and its fair value, is initially recorded as “Grants” in the consolidated statement of financial position, and subsequently recorded in “Other operating income” starting at the entry into operation of the plants. Total amount of income for these two types of grants for Solana and Mojave is $14.7 million and $14.8 million for the three-month periods ended March 31, 2020 and 2019, respectively (Note 20). Other liabilities mainly relate to the investment from Liberty Interactive Corporation (”Liberty”) made on October 2, 2013 for an amount of $300 million. The investment was made in the parent company of the project entity, in exchange for the right to receive a large part of taxable losses and distributions until such time when Liberty reaches a certain rate of return, or the Flip Date. Given the underperformance of the asset in the last years, the Company cannot assure the Flip Date will occur or when it will occur. The company expects potential cash distributions from Solana to go mostly or entirely to Liberty in the upcoming years. If the Flip Date never occurs or if there is a delay longer than currently anticipated, this will adversely affect the cash flows the Company expected from that project. In addition, the Company signed an option to acquire, until August 31, 2020, Liberty’s equity interest in Solana. According to the stipulations of IAS 32 and in spite of the fact that the investment of Liberty is in shares, it does not qualify as equity and has been classified as a liability as of March 31, 2020 and as of December 31, 2019. The liability is recorded in Grants and other liabilities for a total amount of $387 million as of March 31, 2020 ($380 million as of December 31, 2019) and its current portion is recorded in other current liabilities for the remaining amount (Note 17). This liability has been initially valued at fair value, calculated as the present value of expected cash-flows during the useful life of the concession, and is then measured at amortized cost in accordance with the effective interest method, considering the most updated expected future cash-flows. Additionally, other liabilities include $51.7 million of non-current finance lease liabilities and $59.1 million of dismantling provision as of March 31, 2020 ($53.8 million and $59.7 million as of December 2019, respectively).

Basis of preparation [Abstract]
Basis of preparation	The accompanying consolidated condensed interim financial statements represent the consolidated results of the Company and its subsidiaries. The company´s annual consolidated financial statements as of December 31, 2019, were approved by the Board of Directors on February 26, 2020. These consolidated condensed interim financial statements are presented in accordance with International Accounting Standards (“IAS”) 34, “Interim Financial Reporting”. In accordance with IAS 34, interim financial information is prepared solely in order to update the most recent annual consolidated financial statements prepared by the Company, placing emphasis on new activities, occurrences and circumstances that have taken place during the three-month period ended March 31, 2020, and not duplicating the information previously published in the annual consolidated financial statements for the year ended December 31, 2019. Therefore, the consolidated condensed interim financial statements do not include all the information that would be required in a complete set of consolidated financial statements prepared in accordance with the IFRS-IASB (“International Financial Reporting Standards-International Accounting Standards Board”). In view of the above, for an adequate understanding of the information, these consolidated condensed interim financial statements must be read together with Atlantica’s consolidated financial statements for the year ended December 31, 2019 included in the 2019 20-F. In determining the information to be disclosed in the notes to the consolidated condensed interim financial statements, Atlantica, in accordance with IAS 34, has taken into account its materiality in relation to the consolidated condensed interim financial statements. The consolidated condensed interim financial statements are presented in U.S. dollars, which is the Company’s functional and presentation currency. Amounts included in these consolidated condensed interim financial statements are all expressed in thousands of U.S. dollars, unless otherwise indicated. These consolidated condensed interim financial statements were approved by the Board of Directors of the Company on May 6, 2020. Application of new accounting standards a) Standards, interpretations and amendments effective from January 1, 2020 under IFRS-IASB, applied by the Company in the preparation of these condensed interim financial statements: - IFRS 3 (Amendment). Definition of Business. This amendment is mandatory for annual periods beginning on or after January 1, 2020 under IFRS-IASB, earlier application is permitted. - IAS 1 and IAS 8 (Amendment). Definition of Material. This amendment is mandatory for annual periods beginning on or after January 1, 2020 under IFRS-IASB, earlier application is permitted. - IFRS 7 and IFRS 9. Amendments regarding pre-replacement issues in the context of the IBOR reform. These amendments are mandatory for annual periods beginning on or after January 1, 2020 under IFRS-IASB. - Amendments to References to the Conceptual Frameworks in IFRS Standards. This Standard is applicable for annual periods beginning on or after January 1, 2020 under IFRS-IASB. The applications of these amendments have not had any material impact on these condensed interim financial statements. b) Standards, interpretations and amendments published by the IASB that will be effective for periods beginning on or after January 1, 2021: - IFRS 17 ‘Insurance Contracts’. This Standard is applicable for annual periods beginning on or after January 1, 2021 under IFRS-IASB, earlier application is permitted. - IAS 1 (Amendment). Classification of liabilities. This amendment is mandatory for annual periods beginning on or after January 1, 2022 under IFRS-IASB. The Company does not anticipate any significant impact on the consolidated condensed financial statements derived from the application of the new standards and amendments that will be effective for annual periods beginning on or after January 1, 2021, although it is currently still in the process of evaluating such application.
Use of estimates	Use of estimates Some of the accounting policies applied require the application of significant judgment by management to select the appropriate assumptions to determine these estimates. These assumptions and estimates are based on the Company´s historical experience, advice from experienced consultants, forecasts and other circumstances and expectations as of the close of the financial period. The assessment is considered in relation to the global economic situation of the industries and regions where the Company operates, taking into account future development of our businesses. By their nature, these judgments are subject to an inherent degree of uncertainty; therefore, actual results could materially differ from the estimates and assumptions used. In such cases, the carrying values of assets and liabilities are adjusted. The most critical accounting policies, which reflect significant management estimates and judgment to determine amounts in these consolidated condensed interim financial statements, are as follows: • Contracted concessional agreements. • Impairment of intangible assets and property, plant and equipment. • Assessment of control. • Derivative financial instruments and fair value estimates. • Income taxes and recoverable amount of deferred tax assets. As of the date of preparation of these consolidated condensed interim financial statements, no relevant changes in the estimates made are anticipated and, therefore, no significant changes in the value of the assets and liabilities recognized at March 31, 2020 are expected. Although these estimates and assumptions are being made using all available facts and circumstances, it is possible that future events may require management to amend such estimates and assumptions in future periods. Changes in accounting estimates are recognized prospectively, in accordance with IAS 8, in the consolidated income statement of the period in which the change occurs.
