Argentina LNG (YPF, Eni and XRG)
The largest project ever submitted to the RIGI: USD 51,000 million to take Vaca Muerta gas to two floating liquefaction units in the San Matías Gulf, with 12 million tonnes of LNG a year for export from 2031. It announces USD 15,000 million in purchases from Argentine suppliers; the final investment decision is expected by the end of 2026.

How to become a supplier
Argentina LNG SAU, the company YPF set up as the project vehicle and which signed the agreement with Río Negro. A second company for the project or its expansion, still unnamed, may be added with the partners. ⚠️ In practice a small supplier does not invoice the project company: it invoices the contractor of each work package.
YPF runs gas production and buys through its own supplier registry; the large works are awarded by tender to contractors, and they are the ones who buy from small suppliers. According to the trade press, the Plaza Huincul treatment plant is led by the SACDE–Tecnimont joint venture and the two pipelines by Pumpco and Bonatti with Contreras Hermanos, which would be in charge of hiring Argentine suppliers; the floating units and the fractionation plant have no contractor. Two provincial authorities that are not the company also have a say over purchasing: in Río Negro, the Secretariat of Energy and Environment, with the Law 5805 registry, which covers this project and its contractors; in Neuquén, the Centro PyME-ADENEU, which certifies the Neuquén supplier under Law 3338.
The registration routes that exist today, with their status. The one that is up and running is not always the official one.

up and running todayIt is the door to the provincial 60 % floor. The application portal requires a login and publishes neither requirements nor fees in the open; the certificates already issued, by contrast, are public and carry company name, tax ID, city, date, band A or B and the services covered.

up and running todayThis is the platform created by article 9 of Ley 3338, and it publishes the full register: 1,002 certified companies counted one by one on 28 August 2026, with name, location, category and tax ID. It is good for two things before spending a peso: seeing how many competitors you have in your own category, and finding out which categories have almost no certified supply.
Go to the single windowabrirWhat they ask you for
Río Negro's local-purchasing law covers this project and all its contractors: they must give preference to registered Río Negro suppliers verif Sep 1, 2025 ↗Law 5805 applies to «all projects to be executed under the incentive regime of national law no. 27742» (art. 1), and the obligated parties are those authorized for the «transport, storage and treatment of energy resources» in the province and «their contractors and subcontractors» (art. 2).
Registering in the Río Negro Suppliers Register: that is what activates the right to match the best bid with up to an 8% price premium verif Sep 1, 2025 ↗Art. 7 of Ley 5805 requires the Obligated Party to grant the Río Negro Supplier «el derecho de igualar la mejor oferta y obtener la adjudicación», on two conditions: that its bid meets the essential quality, safety and operability requirements of the tender documents, and that its price «no supere la mejor oferta en más de ocho por ciento (8%)»
Being a direct supplier of the liquefaction works, the port, the gas pipeline or the liquids pipeline exempts that work from gross income tax. The fractionation plant is left out verif Mar 9, 2026 ↗The project's gross income tax exemption «extends to the direct suppliers of goods, works or services of the VPUs, exclusively for their participation in the infrastructure works needed to start up the LIQUEFACTION FACILITIES», including port facilities, the transport system and the liquids pipeline. «Infrastructure works related to the FRACTIONATION PLANT shall not be covered by that benefit».
Río Negro's local-purchasing floor can have exceptions: the agreement lets the Province grant them based on the profiles the project reports verif Mar 9, 2026 ↗The project vehicles «will inform the Province of Río Negro of the skills, competencies, training, certifications and experience required» and, with that information, «the Province of Río Negro may establish the corresponding exception measures» under Laws 5594, 2904 (replaced by 5804) and 5805. In parallel, the project promotes a technical and vocational training program with Fundación YPF.
In a joint venture, evidencing that at least 51% of the equity or of the decision-making bodies belongs to people domiciled in Río Negro verif Jun 22, 2026 ↗Decreto 618/26 sets the threshold at 51% of equity or of the decision-making bodies held by people domiciled in Río Negro for a joint venture to qualify as a Río Negro Supplier
In Neuquén, the project's agreements neither create their own local-purchasing rules nor exempt from them: Law 3338 applies as for any operator verif Jul 6, 2026 ↗Neither the GNL Agreement approved by Law 3566 nor the decrees for the five concessions (777, 778 and 779 of 2026) contain clauses on suppliers, local purchasing or local labor. The agreement does bind YPF to an infrastructure bond of USD 175,000,000 in works or cash, to be defined within 90 days of the final investment decision.
The service supplier's contract in the blocks pays Stamp Tax even though the project is exempt verif May 29, 2026 ↗The concession decrees exempt the project's structuring instruments from Stamp Tax, «instruments entered into for the provision of operational services in those Concessions not being included as acts required to structure the project».
Certified Neuquén Supplier status, and the rank decides what it is worth: A gives a 9% margin, B gives 6% verif May 20, 2022 ↗The preference is not a right to charge more: with a bid up to 9 % (band A) or 6 % (band B) above the best non-certified offer, the supplier wins the preference and, having won it, must match that price. What the rule delivers is awarded volume, not unit margin.
The anti-front-company lock: opening a Neuquén subsidiary of an outside firm does not count verif May 20, 2022 ↗«Purchases from controlling or controlled entities, or from members of the same economic group, shall not be treated as purchases from Neuquén companies» (art. 11 of Ley 3338). And a firm that pays most of its taxes in another jurisdiction is capped on the Company regime box. Establishing yourself has to be real and it takes years.
Certifying also gives you access to the operator's purchasing plan BEFORE the tender verif Dec 14, 2022 ↗The implementing decree requires the bound parties to report twice a year —on 15 February and 15 August— everything that will go out to tender, and that plan «shall be kept private and may only be viewed by the Enforcement Authority and Certified Neuquén Suppliers». It is not just 6 or 9 points of preference: it is seeing the purchasing pipeline by category before the market does.
The order you get in by
Register in YPF's supplier registry and pass qualification: it is the door to gas production and to whatever YPF buys directly. The project has no registry of its own. No published timeframe
If the company works in Río Negro: register in the Law 5805 Río Negro Supplier Registry and sign up to the Módulo Compre RN, where obligated parties publish their procurement. Free registration, valid for 12 months; notices are published 5 business days in advance
If it works in Neuquén: get certified as a Neuquén Supplier at the Centro PyME-ADENEU. Besides the price preference, it gives access to the operator's half-yearly purchasing plan before the call for bids.
Approach the contractor of each work package, not the consortium: the SACDE–Tecnimont joint venture for the Plaza Huincul treatment plant and Contreras Hermanos, the local partner of Pumpco and Bonatti, for the pipelines. Both are selected according to the press and subject to the final investment decision.
If you will invoice liquefaction, port, gas pipeline or liquids pipeline works: check with Río Negro's Tax Agency that the gross income tax exemption covers the contract, because it changes the price. It does not apply at the fractionation plant.
Attend the supplier meetings: YPF held one in Plaza Huincul on Aug 11, 2026 with more than 250 companies and another in San Antonio Oeste on Aug 25, 2026 with its procurement, engineering and supplier development teams.

How we verified this
the act, the gaps and the sources
The RIGI act, in detail
The project has been filed under the RIGI and has not been approved yet. The instrument is published in the Boletín Oficial once the Committee approves the accession.
What we could not confirm
There are 4 in this project. Each says why it could not be confirmed and what it would take to close it.
H-01Whether the project appears on the official list of projects under evaluation+
The Ministry of Economy publishes the projects under evaluation only as a total by sector, without names. On Aug 17, 2026 that total rose by USD 51,030 M with one more oil and gas project, four days after this application and by almost the same amount; on Sep 18 it fell by almost the same amount and on Sep 24 it rose again. The match in date and amount is strong, but it is an inference: the spreadsheet does not name it.
H-02How the consortium is split+
None of the three partners publishes its ownership percentage. The split circulating in the press refers to the production blocks, not to the project company.
H-03Who builds the floating units and the fractionation plant+
There is no award for the two floating units or for the fractionation plant. The contractors for the treatment plant and the pipelines are reported only by the trade press: neither YPF nor Eni announced the selection.
H-04How much of the USD 15,000 M for Argentine suppliers goes to each line of business+
The consortium's release gives the total with no breakdown by line of business or by stage, and the 2026-2030 demand that YPF presented in Plaza Huincul is not published.
