Argentina extends the Emergency in the Energy Sector

On June 2nd, 2025, the Government of Argentina released Decree 370/2025 (“Decree 370”), that extends the emergency of the energy sector previously declared by Decree 55/2023 and extended by Decree 1023/2024 (please see our comments here and here), until July 9th 2026.

Decree 307 is applicable to the segments of power generation, transmission and distribution of electric energy, as well as to transport and distribution of natural gas under federal jurisdiction.

Moreover, Decree 307:

  1. Extends the transition towards focalized energy subsidies period until July 9th, 2026 for the Secretary of Energy to continue implementing the necessary acts for the implementation of the measure, to advance in the restructuring of the subsidy regime, and to establish the specific mechanisms to assign and collect them by the users.
  2. Extends the intervention of gas and power regulators –ENRE and ENARGAS– until the new entity established by Foundations Law is constituted or July 9th, 2026, whichever occurs first.

New framework for power transmission system expansions

On June 2, 2025, the Ministry of Economy published Resolution 715/2025 (the “Resolution 715”) which defines the execution of certain expansions of the power transmission system as a priority and indicates that such expansions shall be carried out under the terms of the Public Works Concession Law No. 17,520, a legal framework recently amended by the Foundations Law (Ley Bases) with a strong emphasis on bankability, as described here.

This measure is framed within Decree 55/2023 (as extended by Decree 1023/2024), which declared the emergency of the national energy sector (see our comments on these regulations here and here), and takes into account the high risk of electricity shortages and transmission limitations in Argentina’s federal network.

Resolution 715 establishes that the Secretary of Energy (“SE”) shall approve regulations to include public works concessions within the alternatives for transmission system expansions. Such regulations shall include, among others, that the contractor may finance the expansions by means of a monthly payment to be funded by a rate collected from end-users of the service identified as beneficiaries, as well as that the operation and maintenance of the expansion shall be done by the concessionaire, acting as an Independent Transmission Carrier.

As a result, public works concessions will become a new mechanism for carrying out expansions of the transmission system through private investment and financing. This is a significant measure aimed not only to address the current situation of the system, but also to enable and remove barriers to other industries and projects that are currently limited by the lack of transmission capacity.

Argentina Ratifies the OECD Multilateral Instrument (MLI): Key Changes to Double Taxation Treaties

On May 28, 2025, the National Executive Branch enacted and published Law No. 27,788 in the Official Gazette, thereby formally approving the Multilateral Convention to Implement Tax Treaty Related Measures to Prevent Base Erosion and Profit Shifting (commonly referred to as the Multilateral Instrument, the “MLI”), signed in Paris, France, on November 24, 2016.

Regarding the legislative process that led to its approval, it is worth noting that Argentina was one of the original signatories of the MLI on June 7, 2017, in alignment with its commitment to international standards on transparency and the fight against tax avoidance. The bill was submitted to the Senate in October 2024, following initial approval by the Chamber of Deputies. The National Congress gave final approval on May 7, 2025. With its enactment by the Executive on May 28, 2025, and publication in the Official Gazette, the constitutional process required for the MLI’s incorporation into domestic law was completed, granting it full legal effect in Argentina.

Pursuant to Article 34 of the MLI, the Convention will enter into force at the international level, and with respect to Argentina, on the first day of the month following the expiration of a three-month period from the date the country deposits its instrument of ratification with the OECD Secretariat.

Once effective, the provisions of the MLI will apply in accordance with Article 35 as follows:

  • With respect to withholding taxes (e.g., on dividends, interest, and royalties), the MLI will apply from January 1 of the calendar year following the latest date on which the MLI enters into force for both Contracting Jurisdictions. If such date occurs during 2025, the provisions will become applicable as of January 1, 2026.
  • With respect to other taxes (such as income taxes assessed by means of tax returns, e.g., Corporate Income Tax), the MLI will apply to taxable periods beginning six months after the latest date of entry into force between the two jurisdictions, unless an alternative date is notified in accordance with Article 35.

Domestic Implications of the MLI

Argentina’s adoption of the MLI is part of a global initiative led by over 100 jurisdictions under the OECD/G20 BEPS Project, aimed at rapidly and consistently updating the network of international tax treaties and minimizing opportunities for tax avoidance by multinational groups.

The MLI is designed to counteract aggressive tax planning strategies that erode tax bases and shift profits artificially to low or no-tax jurisdictions. Its implementation enables Argentina to simultaneously update its existing Double Tax Treaties (“DTTs”) without having to renegotiate each agreement bilaterally.

The MLI will modify Argentina’s DTTs with jurisdictions such as Spain, Italy, Mexico, the Netherlands, Switzerland, and the United Kingdom, among others, in order to curb treaty abuse by arrangements lacking economic substance, consistent with Argentina’s international commitments to tax transparency and anti-avoidance measures.

Key Anti-Abuse Provision: Principal Purpose Test (PPT)

One of the main reforms introduced by the MLI is the Principal Purpose Test (“PPT”).

The PPT provides that treaty benefits—such as reduced withholding tax rates—may be denied if, considering all facts and circumstances, it is reasonable to conclude that one of the principal purposes of an arrangement or transaction was to obtain that tax benefit, unless it is established that granting such benefit would be consistent with the object and purpose of the treaty.

The MLI also amends the preambles of Covered Tax Agreements to reinforce their anti-abuse objective. Article 6 mandates the inclusion of the following text:

"Intending to eliminate double taxation with respect to the taxes covered by this agreement without creating opportunities for non-taxation or reduced taxation through tax evasion or avoidance (including through treaty-shopping arrangements aimed at obtaining reliefs provided in this agreement for the indirect benefit of residents of third jurisdictions)".

Such wording will be added in the absence of an equivalent preamble or will replace an existing one that does not sufficiently express this objective. Jurisdictions that already include a substantially equivalent preamble may opt out of this modification.

Practical Implications of the PPT

  • The PPT will apply automatically unless a jurisdiction makes a reservation (which Argentina has not done).
  • It does not require proof of fraud or tax evasion—only the existence of a principal tax purpose.
  • Tax authorities may deny treaty benefits where aggressive tax planning or artificial structures without substance are detected.
  • The burden of proof shifts to the taxpayer, who must demonstrate valid economic reasons for cross-border transactions.

Alternative to the PPT: Simplified Limitation on Benefits (S-LOB)

In addition to the PPT, the MLI allows jurisdictions to apply a supplementary rule known as the Simplified Limitation on Benefits (“S-LOB”).

This provision restricts treaty benefits to specific “qualified residents,” including:

  • Individuals;
  • Governments, political subdivisions, local authorities, and their wholly owned agencies or instrumentalities;
  • Companies whose shares are regularly traded on recognised stock exchanges;
  • Pension funds and non-profit entities that are regulated and recognized as such by the contracting jurisdictions.

However, Argentina has not yet adopted the S-LOB clause, making the PPT the sole anti-abuse rule applicable under the MLI.

Privatization of Energía Argentina S.A. – Sale of shares in CITELEC

On April 25, 2025, Decree No. 286/2025 (“Decree 286”) was published in the Official Gazette, authorizing the full privatization of Energía Argentina S.A. (“EA”) and the sale of its equity interest in CITELEC.

Decree 286 foresees that EA will be privatized in stages, through the separation of the activities and assets of its different business units, ensuring that the performance of services and works currently under EA’s scope is not interrupted.

Thus, with the approval of the sale of EA’s shares in CITELEC, the first stage of EA’s privatization has begun.

EA holds 50% of the shares of CITELEC, a company that is the controlling shareholder of TRANSENER, which in turn holds 99.9% of the shares in TRANSBA (the remaining 0.1% is held by CITELEC).

TRANSENER is the extra-high voltage power transmission utility operating nationwide; TRANSBA, in turn, is the utility for trunk power transmission in the Province of Buenos Aires.

The sale of EA’s shares in CITELEC will be carried out through an international and national public bidding process, pursuant to Articles 17(2) and 18(2) of the State Reform Law No. 23,696, as amended.

The Ministry of Economy, with the involvement of the Special Temporary Executive Unit for the Transformation of State-Owned Companies (ATEP), will issue the necessary regulations to implement  Decree 286.

Privatization of Hydropower facilities

On April 10, 2025, the Government of Argentina published Decree 263/2025 (“Decree 263”), which advances the sale process of the following companies: (i) Alicurá Hidroeléctrica Argentina S.A., (ii) Chocón Hidroeléctrica Argentina S.A., (iii) Cerros Colorados Hidroeléctrica Argentina S.A., (iv) Piedra Del Águila Hidroeléctrica Argentina S.A., (v) Cerros Colorados Hidroeléctrica Argentina S.A. and (vi) Piedra Del Águila Hidroeléctrica Argentina S.A. (the “Companies”). These Companies are currently owned by Energía Argentina S.A. (“EA”) (98%) and Nucleoeléctrica Argentina S.A. (“NASA”) (2%). Both EA and NASA have been subject to privatization pursuant to Article 7 and Annex I of Foundations Law.

Decree 263 establishes a period of fifteen (15) days since its publication to launch a National and International Public Bidding process for the sale of the controlling shareholding in the Companies (the “Call for Bids”), currently held by EA and NASA.

The Call for Bids will be carried out by both the Agency for the Transformation of State-Owned Companies (Agencia de Transformación de Empresas Públicas) and the Secretary of Energy.

Decree 263 builds upon Decrees 718/2024 and 895/2024, which had initiated the privatization process of the Companies.

Approval of LNG Export Procedure

On April 4, 2025, the Secretary of Energy published Resolution 145/2025, which approved the Liquefied Natural Gas Export Procedure (the “Procedure” and “LNG,” respectively). This measure was implemented in the framework of article 2 of Annex II of Decree 1057/2024 (see our comments on the decree here), which established that the Secretary of Energy would regulate the applicable procedure for LNG exports.

1. LNG export notification

According to the Procedure, companies interested in exporting LNG must submit an application, providing information regarding projected availability, reserves and production capacity for at least five (5) years as of the submission, maximum export LNG volumes, proof of filing with the Large Investments Incentive Regime (“RIGI”, for its acronym in Spanish) -if applicable-, and technical feasibility of the project. The Liquid Fuels Undersecretary shall analyze the information and issued observations or request additional information within ten (10) business days as of the date of submission. The Secretary of Energy may issue observations on the application -within one hundred and twenty (120) business days-, based on insufficient natural gas availability for the country or inaccuracies in the filing. The applicant shall have thirty (30) business days to rectify its application and once the observations are resolved, the Secretary of Energy will issue the certificate of “LNG Free Export Authorization”.

2. LNG export authorization

This authorization shall indicate the term of the exports, the LNG volumes and the frequency of reports to be required by the authority. The authorized company shall report, no less than ninety (90) days prior the first export, the volumes and prices, the registration as a storage operator with the Natural Gas Storage Registry of the Republic of Argentina (“RAGNar”) and submit proof of authorization with the Customs Registry System.

LNG exports will be authorized on a firm basis -non-interruptible- for a period of thirty (30) years as of the commissioning date of the liquefaction plant (including expansions or later stages). Provided that the required availability is periodically confirmed, the exporter shall have the right to export LNG on a continuous basis, without interruptions, restrictions or reductions, and shall have access to production, transport, processing and storage of natural gas to carry out LNG exports.

3. Exporter's duties

LNG exporters must ensure ongoing gas availability and prove within six (6) months prior to the current availability accreditation expires, that they have sufficient gas to cover the following five (5) years. Exporters must also report any changes regarding the information submitted in the application.

4. Term and assignment of authorization

Lastly, according to the Procedure, the export authorization expires automatically on the date established therein, though it can be revoked for exporter’s non-compliance with its obligations. The export authorization may be transferred to another party with prior approval of the Liquid Fuels Undersecretary, provided the assignee meets all the requirements of the Procedure.
