Chile had more than 38,193 MW of installed capacity in operation in March, 51% of which came from non-conventional renewable energy sources, according to the Ministry of Energy’s March Energy Sector Construction and Investment Projects Report. The report also identifies 138 energy projects under construction, including power plants, transmission facilities and storage infrastructure, representing a combined investment of $11.7 billion.
In energy storage, there are 38 systems under construction, with a total of 4,597 MW / 18,780 MWh and an investment of $4.1 billion. In addition, 13 systems are being tested, with a capacity of 2,119 MW / 9,708 MWh. Two new systems were commissioned in March: the 200 MW / 1,000 MWh BESS Víctor Jara in Tarapacá, and the 171 MW / 514 MWh BESS Andes III – Phase I in Antofagasta .
In terms of power generation, the report records 53 power stations under construction, with a total capacity of 3,325 MW and an investment of US$4.605 billion. Solar technology accounts for 69% of capacity, with 2,294 MW, and 51% of investments, with $2.340 billion. Wind energy follows, with 793 MW and $1.561 billion.
The largest generation projects under construction are in Antofagasta: PFV + BESS Cristales, with 400 MW of solar energy and a 340 MW / 1,360 MWh system, and the Pampas Hybrid Project, with 348 MW of generation and 340 MW / 1,360 MWh of storageboth from AES Andes.
The ministry indicates that the target of 2,000 MW of storage for 2030 has been achieved on March 31, 2026 with the commissioning of the above projects. The report adds that, given the projects currently underway, the 2050 target of 6,000 MW would be achieved by the end of 2026 or early 2027.
According to the Environmental Impact Assessment System (SEIA), the energy sector ended March with 141 projects under environmental assessment, totaling $51.664 billion. Of that total, 105 correspond to power plants, representing 13,123 MW and $19.691 billion; 21 to standalone storage, which amounts to 4,625 MW / 23,493 MWh and $4.666 billion; 13 to transmission lines, covering 63 km and worth $307 million; and two for green hydrogen, both in Magallanes, worth $27 billion.
Currently, 47 projects for the national and zonal systems are under construction, representing 2,096 km of new lines and an investment of USD 3 billion. The largest investment project is the Kimal – Lo Aguirre HVDC electrical transmission line, a 500 kV, 1,342 km line with an investment of $2 billion.
