Argentina achieved new renewable energy records in the Argentine Interconnection System (SADI) after reaching historic highs in wind power generation, variable renewable energy and total renewable energy in less than 24 hours.
According to CAMMESA , on April 28 at 23:10, national wind power generation reached 4064 MW , out of an enabled capacity of 4559 MW , equivalent to a load factor close to 89% .
Subsequently, on April 29 at 12:10, variable renewable generation —considering wind and solar— reached a new record of 5,954 MW , out of an installed capacity of 7,214 MW , with a load factor of 82% .
Simultaneously, also considering bioenergy and small hydroelectric plants, the system recorded a record high of 6308 MW of total renewable generation .

In fact, at different times during the day, renewable energies supplied more than 55% of the national electricity demand .

Furthermore, the integrated operation between Argentina and Uruguay set a joint record of 6981 MW of renewables .
These records occur in a context of expansion of installed capacity in the Wholesale Electricity Market (MEM), which currently totals 17,692 MW of renewable energy, including wind, solar, bioenergy and hydropower.
Wind energy continues to lead among the technologies of Law 26.190 with 4559 MW installed , while solar photovoltaic has already reached 2655 MW .
Patagonia currently has 1,662 MW of wind power capacity, while Buenos Aires and its metropolitan area account for another 1,999 MW . Meanwhile, the Cuyo region has 1,255 MW of solar power and the Northwest region (NOA) another 875 MW of photovoltaic capacity , consolidating their positions as the country's main solar power generation hubs.
In bioenergy, the system already has 337 MW installed , while small hydroelectric plants reach 501 MW .
CAMMESA highlights that these milestones demonstrate "the sustained progress of renewable energies in the electricity matrix and the challenges associated with their real-time operation within increasingly dynamic and interconnected systems."
Renewable energy growth also increases the operational complexity of the SADI (Argentine Interconnected System). The greater participation of variable energy sources requires strengthening real-time dispatch, weather forecasting, regional coordination, and the management of electricity transmission constraints.
In this scenario, energy integration with Uruguay gains strategic relevance to provide flexibility to the system and improve operational management during periods of high renewable generation.
At the same time, the sector continues to face infrastructure limitations, mainly related to transmission capacity in regions with strong renewable potential such as Patagonia and the NOA.
The new highs recorded again show that Argentina continues to increase the share of clean energy within its electricity mix, in parallel with the growth of installed renewable capacity throughout the country.
