What Central Puerto does

Central Puerto S.A. is Argentina's largest private power generation company, operating a diversified portfolio of approximately 6.94 GW of installed capacity across 16 plants and accounting for roughly 17% of the Argentine Interconnection System (SADI) market. The portfolio spans thermal generation (Central Costanera at 2,305 MW, San Lorenzo cogeneration at 330 MW, Central Térmica Mendoza at 562 MW, Brigadier López combined cycle), hydroelectric (Piedra del Águila at 1,440 MW under a 30-year concession renewed in December 2025 for $245 million), wind (La Genoveva I & II, CP Manque, CP Los Olivos totaling approximately 210+ MW), solar (Guañizuil II A, plus the 140 MW Hunuc I and 300 MW Centenario projects under development in San Juan), and battery storage (the 150 MW Puerto Nuevo/AlmaGBA project, with 205 MW total under construction). The company generated 18,603 GWh annually and reported FY 2024 revenue of $782.60 million with net income of $249.40 million.

The business operates across four primary revenue streams: (1) wholesale electricity sales to CAMMESA under regulated capacity payments and energy dispatch; (2) bilateral corporate power purchase agreements under the MATER program and direct long-term contracts with industrial buyers (e.g., Cervecería y Malteria Quilmes, Terminal 6, AXION energy); (3) industrial steam and cogeneration services sold under 15-year contracts from San Lorenzo and Luján de Cuyo; and (4) emerging revenue from oil & gas production (Vaca Muerta via the April 2026 acquisition of Patagonia Energy S.A., covering ~110 km² in the Neuquén Basin) and equity returns from minority mining stakes (AbraSilver Resource Corp. at 9.9% and 3C Lithium's Tres Cruces lithium project). The company's customer base spans industrial consumers, mining operators, beverage and food processors, and — via a new partnership with Sur Energy and OpenAI — hyperscale AI data center developers.

Central Puerto's competitive position rests on regulatory concessions, scale-driven cost economics, and an increasingly integrated energy platform that now spans electricity generation, oil & gas, mining, forestry (160,000+ hectares acquired via Masisa and EVASA), and transmission infrastructure development. The company is controlled by national Argentine shareholders (Guillermo Reca, the Miguens-Bemberg family, Eduardo Escassany), has been listed on the NYSE (CEPU) and BYMA since 2018, and relies on multilateral financing partners (notably IFC, with $300 million committed in December 2025) to fund its expansion pipeline. Strategic direction is captured under the corporate tagline "Energía con Futuro" (Energy with Future), reflecting its diversification across conventional, renewable, storage, and hydrocarbons assets.

Revenue model

1. Electric Power Generation and Sales: Central Puerto generates and sells electricity through the Argentine wholesale electricity market (CAMMESA), under regulated capacity payments, and through bilateral PPAs with corporate clients. Revenue is driven by energy volume dispatched, capacity availability payments, and spot/contract prices. The company holds 17% national market share with 6.94 GW of installed capacity.
2. Industrial Steam and Cogeneration Services: Cogeneration plants (San Lorenzo, Luján de Cuyo) sell both electricity and industrial steam to private clients under 15-year contracts. Steam revenue provides stable, contracted income alongside electricity generation.
3. Mining and Critical Minerals Investments: Through subsidiaries Proener S.A.U. and other holdings, Central Puerto holds equity stakes in mining companies (AbraSilver Resource Corp. at 9.9%, 3C Lithium / Tres Cruces project) and is developing power supply for lithium mining operations, diversifying into metals production and energy-for-mining services.
4. Oil & Gas Production (Vaca Muerta): Following the April 2026 acquisition of Patagonia Energy S.A. (PESA) and Patagonia Assets Limited, Central Puerto entered the hydrocarbons sector with approximately 110 km² of assets in the Aguada del Chivato and Aguada Bocarey areas in the Neuquén Basin, marking its first oil & gas revenue stream.
