Argentina Commissions 360 MW El Quemado Solar Park as Country's Largest Photovoltaic Plant

The province of Mendoza has inaugurated the 360 megawatt El Quemado Solar Park in the department of Las Heras, making it the largest photovoltaic plant in Argentina and surpassing the 315 megawatt Cauchari complex as the country's biggest solar facility. The $220 million project was originally developed by provincial utility Empresa Mendocina de Energia Sociedad Anonima before being acquired and built by YPF Luz, with the first 100 megawatt unit entering commercial operation in December 2025. Officials highlighted that El Quemado is the first renewable energy project approved under Argentina's Large Investment Incentive Regime, a framework designed to attract investments through fiscal, customs and foreign exchange incentives, positioning it as a flagship reference for the country's broader renewable energy investment push.

 

Project Specifications and Construction

 

El Quemado spans approximately 620 hectares and comprises more than 511,000 bifacial solar modules, 5,800 trackers, 1,170 inverters and 40 transformer stations. The facility has an estimated capacity factor of 31.4 percent, reflecting the strong solar resources available in Argentina's sunny Cuyo region. Annual generation is projected to be sufficient to cover residential electricity demand in the city of Mendoza alongside the departments of Las Heras and Lavalle, providing a meaningful contribution to regional clean energy supply.

Construction lasted 18 months and peaked at more than 350 workers, with 87 percent of labour sourced locally to maximise economic benefits for surrounding communities. Key technology suppliers included JinkoSolar, Arctech Solar and Huawei, reflecting the deep involvement of leading global suppliers in Latin American utility-scale solar deployments. The grid connection works included a new transformer station linked to the Argentine Interconnection System, alongside a substation equipped with GIS technology and 180 kilometres of fibre-optic cabling for control and protection systems.

Power Purchase Agreements and Offtake Profile

 

YPF Luz has secured several power purchase agreements that anchor the commercial viability of El Quemado and complementary projects across its portfolio. In December 2025, the company signed an agreement with Molinos Rio de la Plata to extend a renewable supply contract to 2030, raising the food producer's clean energy share to as much as 80 percent with potential to reach 100 percent in the future. The agreement builds on a prior contract from September 2023 that included the 100 megawatt Zonda Solar Park in San Juan and now incorporates generation from El Quemado.

In March 2026, YPF Luz signed a three-year agreement with Argentine digital infrastructure company Skyonline to supply approximately 7,200 megawatt hours annually, covering 85 percent of the electricity demand of Skyonline's data centre in downtown Buenos Aires. The contract draws supply from both El Quemado and the General Levalle Solar Park in Cordoba. In April, the company also announced an agreement with Molinos Basile covering 50 percent of the food company's electricity demand, equivalent to around 2,200 megawatt hours per year.

 

Strategic Significance for Mendoza and Argentina

 

With El Quemado now online, Mendoza province exceeds 700 megawatts of installed solar capacity and is moving toward a provincial pipeline projected to surpass 1 gigawatt. Upcoming developments include the Anchoris and San Rafael projects, each with 180 megawatts of capacity, which would further consolidate Mendoza's position as one of Argentina's leading renewable energy provinces. The province benefits from strong solar irradiance combined with available land and supportive provincial policy frameworks, creating favourable conditions for continued project development.

The completion of El Quemado under the Large Investment Incentive Regime also establishes an important precedent for future renewable energy investment in Argentina. The framework provides fiscal, customs and foreign exchange incentives that are intended to attract international capital into long-term infrastructure projects despite the country's broader macroeconomic challenges. Successful execution of El Quemado validates the regime's effectiveness and may encourage further large-scale renewable energy commitments in the coming years.

Outlook for Argentine Solar Development

 

The El Quemado commissioning reflects a broader pattern in which Latin American countries are accelerating utility-scale solar deployment to support domestic electricity demand and economic development. Argentina is positioned to benefit from strong solar resources combined with rising commercial and industrial demand for renewable power, particularly from corporate buyers seeking to reduce emissions and lock in long-term electricity costs. Continued expansion of corporate PPA volumes would provide the offtake foundation needed to support further project development.

Whether Argentina can sustain its renewable energy growth trajectory will depend on continued policy stability, macroeconomic conditions and the success of frameworks such as the Large Investment Incentive Regime in attracting international capital. Sustained execution would position the country as one of the more dynamic renewable energy markets in Latin America. The completion of El Quemado at scale establishes a meaningful reference point that could support further investment as developers and lenders evaluate the country's evolving project finance environment.
