Argentina Adds 810 MW of Solar in 2025, Total Capacity Reaches 2.48 GW

Argentina’s installed solar capacity climbed to 2,483 MW in 2025, following the addition of approximately 810 MW of new projects during the year, according to data from Compañía Administradora del Mercado Mayorista Eléctrico (CAMMESA).

The 2025 result marks a sharp increase compared with 2024, when the country installed 307 MW of new PV capacity.

Renewables Mix: Wind Leads, Solar Second

Total installed renewable energy capacity in Argentina now stands at 7,879 MW, excluding hydropower plants larger than 50 MW, which account for an additional 9,640 MW.

According to CAMMESA, wind power represents the largest share of renewable capacity at 4,559 MW, followed by:

· Solar: 2,483 MW

· Small hydropower (<50 MW): 501 MW

· Biomass: 336 MW

Solar energy remains the country’s second-largest renewable source by installed capacity.

Cuyo and Northwest Drive Solar Growth

Solar capacity in Argentina is heavily concentrated in the Cuyo and Northwest (NOA) regions.

The Cuyo region — comprising Mendoza and San Juan — accounts for 1,095 MW of installed solar capacity. At least 510 MW was connected in 2025 following the commissioning of several projects in Mendoza, including:

· Malargüe I (90 MW)

· Anchoris (180 MW)

· The first 100 MW phase of El Quemado (planned total capacity: 305 MW)

· 140 MW of the 180 MW San Rafael project

Meanwhile, Northwest Argentina (NOA) — including Jujuy, Salta, Tucumán, Catamarca, Santiago del Estero and La Rioja — holds 869 MW of installed solar capacity.

Other Regional Contributions

The remaining solar capacity is distributed across other regions:

· Northeast Argentina (NEA) — Chaco, Misiones, Corrientes and Formosa: 310 MW

· Central Argentina — Córdoba and San Luis: 198 MW

· Comahue — La Pampa, Neuquén and Río Negro: 10 MW

· Litoral region — including Santa Fe and Corrientes: 1 MW

With annual additions more than doubling year-on-year, Argentina’s solar sector is showing renewed momentum, strengthening its position within the country’s evolving renewable energy mix.
