SIMM Soluciones, a Brazilian engineering, procurement, and construction (EPC) company, is strengthening its presence in Argentina with a clear objective: to become a leading contractor in renewable energy and battery energy storage systems (BESS) projects.
With more than 8 GW of renewable capacity delivered across Latin America, the company sees a significant opportunity in Argentina, where it identifies a shortage of experienced firms capable of executing energy infrastructure projects at scale.
According to Jorge Andri, SIMM’s regional experience includes over 1,500 wind turbines installed, more than 20 substations of up to 500 kV, and approximately 1,800 km of transmission lines. While it has previously participated in wind projects across the region, the firm is now prioritizing local operations in Argentina and Chile, with plans to expand into Peru.
For 2026, SIMM aims to build one solar PV project, develop two to three BESS initiatives, and continue executing electromechanical assembly of wind turbines. This push is driven by what the company describes as a structural gap in Argentina’s energy construction market: large contractors often overlook mid-sized renewable projects, while smaller firms may lack the technical and financial capacity to deliver them.
To address this, SIMM is deploying an integrated model covering engineering, construction, and maintenance, while also incorporating energy storage and digital infrastructure such as data centers into its growth strategy. The company entered the BESS segment in 2025 with a 40 MW, 4-hour battery system in Chile linked to a wind farm, and has since advanced engineering for several storage projects across Brazil, Chile, and Argentina, including one in northern Greater Buenos Aires.
SIMM is also targeting upcoming opportunities under the AlmaSADI tender, a government-backed initiative launched in March to procure 700 MW of stand-alone BESS projects ranging from 10 MW to 150 MW, with contracts of up to 15 years. The tender is expected to support grid flexibility, renewable integration, and long-term investment in storage capacity.
In Argentina, the company is offering a full-service portfolio that includes solar plant construction, wind turbine installation, electrical balance of plant (BOP), asset maintenance, and engineering supervision. Its competitive positioning, according to Andri, lies in execution reliability and the ability to deliver projects on time in emerging markets.
SIMM’s expansion takes place in a context of sustained growth in Argentina’s power sector, which currently has շուրջ 7,980 MW of installed renewable capacity, largely driven by wind and solar. At the same time, rising electricity demand—particularly from the mining sector—is increasing pressure on the system, especially in regions with high solar potential such as the Andes.
However, transmission infrastructure remains a key bottleneck for further expansion. The national government is advancing regulatory frameworks to enable private investment in medium- and high-voltage networks, which could unlock new opportunities for companies involved in substation and grid construction.
With more than 15 years of experience, SIMM aims to consolidate its position as a strategic partner for developers and investors, aligning its capabilities with Argentina’s evolving needs in renewable energy, energy storage, and grid infrastructure modernization.
