In a semester marked by historic achievements, wind farms positioned themselves as the main growth engine of the Argentine renewable energy sector, surpassing all other green technologies.
Their performance not only consolidated leadership in sustainable production but also strengthened national energy coverage, reaching a 18% share of electric demand.
This progress is reflected in the latest report from the Compañía Administradora del Mercado Mayorista Eléctrico (Cammesa), which reported a cumulative generation of 12,440 GWh of clean energy in the first semester of 2025, marking a 17% year-on-year increase compared to the 10,630 GWh recorded during the same period the previous year.
As in previous years, wind energy led renewable production, followed by solar. In contrast, Small Hydroelectric Uses (SHU) were the only ones to experience a decline.
New projects and expansions accelerate wind energy installed capacity in Argentina
The growth of national wind generation was mainly driven by the expansion of installed infrastructure. During this semester, significant parks were inaugurated and expanded in Córdoba, Buenos Aires, and La Rioja, increasing total capacity and anticipating new records in the second half of the year.
In April, YPF Luz activated the General Lavalle wind farm, with 25 6.2 MW wind turbines each, reaching a total capacity of 155 MW. The project required an investment of US$260 million, boosting the company’s renewable capacity to 652 MW.
In May, Genneia, the main operator in the sector, added its eighth wind farm in Buenos Aires: La Elbita, with 162 MW of power and 36 wind turbines, after an investment of US$240 million.
At the beginning of June, the third phase of the Arauco Wind Farm (AWF III) was inaugurated in La Rioja. With 28 turbines and an investment of US$145 million, the complex reached 250 MW installed capacity, becoming the largest renewable hub in northern Argentina.
On the other hand, two significant ongoing developments were announced:
- AES reported the expansion of its Vientos Bonaerenses project, located between Bahía Blanca and Tornquist. With an investment of US$150 million, it will double its capacity to 102.4 MW within 18 months.
- Tenaris (Techint Group) presented its second wind farm, La Rinconada, with 94.5 MW of power and 21 4.5 MW wind turbines each. Civil works in Olavarría have already begun, with an investment exceeding US$200 million.
Wind energy grows in Argentina[/caption>
Performance by technology in the first semester
Out of the 1,800 additional GWh generated compared to the same period in 2024, 70% came from wind energy, accumulating 8,862 GWh, reflecting a 17% year-on-year increase compared to the 7,586 GWh from the previous semester.
Solar energy also showed remarkable performance, growing by 25%, with 2,175 GWh generated and 441 additional GWh, thanks to the incorporation of new installations in high irradiation regions.
On the other hand, bioenergies —although with a lower share in the energy mix— contributed to the increase: 144 GWh from biomass plants and 3 GWh from biogas.
The only segment with a negative performance was that of Small Hydroelectric Uses, which reduced its contribution by 7% year-on-year, remaining at low levels due to unfavorable hydrological conditions.
Projection: increased installed capacity and renewable leadership
With projects under construction and expansions in progress, the trend for the second semester and the end of 2025 anticipates sustained growth in the wind sector, which continues to set the pace for the country’s energy transition.
This momentum allows not only to expand electric demand coverage with clean sources, but also to consolidate Argentina as a regional benchmark in renewable energy. The priority dispatch for these technologies, combined with high social acceptance, contributes to strengthening the path towards a diversified and low-carbon energy matrix.
