Argentina RIGI investment commitments have climbed to approximately US$49 billion across 23 approved projects, Economy Minister Luis Caputo announced on July 31, 2026, following the admission of a US$2.7 billion urea megaplant by Pampa Energía and a US$360 million expansion by Compañía MEGA into the country’s flagship incentive regime.
Pampa Energía’s US$2.7 Billion Urea Megaplant
Pampa Energía’s board approved the final investment decision on July 17, 2026, for a US$2.7 billion granular urea plant to be built in Bahía Blanca, southern Buenos Aires Province. The facility will be developed by Fértil Pampa S.A.U., a wholly owned subsidiary, on an 80-hectare site inside the Bahía Blanca port area.
The company stated the plant will have an annual production capacity of 2.1 million tons of granular urea, which would make it the largest urea plant in Latin America by capacity. The project scope includes an ammonia plant, a two-train granular urea plant with a combined capacity of 6,000 tons per day, a desalination plant, storage silos, and logistics infrastructure at the Port of Bahía Blanca.
Pampa highlighted that the site has direct access to the Vaca Muerta natural gas pipeline system, noting that natural gas and electricity will account for roughly 70% of urea production costs. Construction is expected to take about three and a half years (~42 months), with production targeted to begin in 2029.
Compañía MEGA’s US$360 Million Expansion
On July 31, 2026, the government also admitted Compañía MEGA to the RIGI for an investment of US$360 million. Caputo said the project will increase production capacity of natural gas liquids by 1,500 tons per day.
The company had indicated in March that its broader expansion plan runs from 2023 to 2028 and totals US$650 million. The RIGI-covered stage focuses on new pumping stations and transport capacity toward Bahía Blanca, with works spanning four Argentine provinces and linked to Vaca Muerta development.
How the RIGI Mechanism Works
The RIGI, or Régimen de Incentivo para Grandes Inversiones (Incentive Regime for Large Investments), is a centerpiece of President Javier Milei’s economic strategy to attract foreign and domestic capital. The scheme offers a suite of tax, customs, and legal stability benefits designed to provide long-term certainty for projects exceeding a minimum investment threshold.
Key features include a reduced corporate income tax rate, accelerated depreciation, exemptions from export duties after a set period, and access to foreign exchange markets without certain restrictions that apply to other sectors. The regime also provides regulatory stability, meaning the rules in place at the time of a project’s approval cannot be altered to the investor’s detriment for a defined period.
Milei’s Broader Investment Push
The RIGI approvals form part of President Milei‘s broader push to deregulate Argentina’s economy and attract large-scale investment, particularly in energy and natural resources linked to the Vaca Muerta shale formation. The government has framed the regime as essential to unlocking Argentina’s potential as a global energy and commodities exporter.
Earlier official tallies had shown 16 approved projects worth US$29.892 billion as of June 2026, indicating substantial growth before the July 31 update. Some variation in reported totals has occurred because certain sources count only formally approved projects while others include submitted or under-review proposals.
What the Projects Mean for Argentina
The Pampa Energía urea plant represents a significant move into value-added industrial production using Vaca Muerta natural gas, rather than simply exporting the raw resource. Urea is a key fertilizer for global agriculture, and the plant positions Argentina as a major supplier to regional and international markets.
The Compañía MEGA expansion, meanwhile, strengthens midstream infrastructure for natural gas liquids, a critical component for petrochemical industries and energy exports. Together, the two projects highlight the government’s focus on leveraging Vaca Muerta to drive industrial development and export diversification.
