Argentina LNG Consortium Files for RIGI Tax Incentives as $51 Billion Project Advances
Eni and partners applied on Friday (2026-08-14) for Argentina's investment stabilisation regime, seeking 30-year tax and currency protections for the 12 MMtpa two-FLNG project.
The Argentina LNG consortium filed an application on Friday (2026-08-14) for the country's Large Investment Incentive Regime, known as RIGI, co-owner Eni SpA confirmed. The move locks in the project's formal bid for a 30-year package of tax, customs, and foreign exchange benefits under rules President Javier Milei's government passed in 2024.6,7
Under the regime's oil and gas provisions, export production projects must clear at least $600 million in investment to qualify — a bar the Argentina LNG consortium clears by a wide margin, with total planned capital estimated at roughly $51 billion by the Buenos Aires Times. PAMPA Investment Advisory puts the stability floor for broader RIGI eligibility at $200 million, though the oil and gas-specific threshold is higher.6,7
The 30-year protection clause carries particular weight in Argentine context. Under Milei's government the guarantee holds even if later administrations enact more restrictive regulations, according to the government's own framing of the regime. Argentina's history of currency controls, windfall levies, and policy reversals makes that promise commercially significant, even if it remains politically untested over three decades.6
The project consists of two floating liquefaction units with a combined capacity of 12 million metric tons per annum. The partners announced the joint development agreement on February 12 (2026-02-12), describing upstream gas transportation, processing facilities, and export infrastructure alongside the two FLNG units. Eni described the same technical configuration in its statement accompanying the RIGI filing.6,7
Upstream feed gas supply runs through Vaca Muerta. Eni signed an agreement on June 29 (2026-06-29) to acquire a 32% stake in three unconventional gas blocks in the shale formation, entering alongside XRG, the international investment arm of Abu Dhabi's ADNOC. That upstream deal directly links the two companies' FLNG equity to feedstock access, reducing supply-side uncertainty for lenders and offtakers assessing project bankability.3,45
XRG's involvement reflects broader strategic targeting. The Abu Dhabi vehicle has set a public goal of building a top-five integrated gas and LNG business with capacity of 20 to 25 million MMtpa by 2035, a target announced on June 3, 2025. Argentina LNG represents one of several large-scale positions the company has accumulated as global LNG investment has accelerated.6
On the logistics side, Adani Ports and Special Economic Zone secured a 10-year marine services contract for the project in early June (2026-06-07), committing approximately $70 million to support operations. The fleet involves four high-specification tugboats, one anchor handling tug supply vessel, and one crew boat. Commercial operations are scheduled to begin in September 2027, with first-phase production expected at 2.45 million tonnes per year, around 28 cargoes annually.1,2
That 2027 start date sits alongside an ambition that deserves scrutiny. Separately cited forecasts suggest Argentina is targeting LNG exports of up to 10 million tonnes per year to India by 2027. The first-phase capacity of 2.45 MMtpa falls well short of that figure, and no source in this packet explains how the gap would be bridged within the timeline. The $51 billion total investment figure suggests the full build-out is a multi-decade programme, not a near-term delivery.1,7
Asian spot LNG, the JKM benchmark, was assessed at $21.41 per MMBtu at the August 15 close, according to market data. That level offers a meaningful netback to potential Argentine export economics, though project returns over a 30-year horizon will be shaped by contract structures and capital costs not yet made public.
The RIGI application is a procedural step, not a final investment decision. Financing terms and the path to FID remain unannounced. The 30-year stability guarantee becomes the key commercial assumption underwriting all of it — and Argentina's capacity to honour that guarantee across multiple election cycles is the variable no incentive regime can resolve on paper.6,7
