A total of 104 electric power projects are under construction in Chile with a combined installed capacity of 5,316MW.

According to data from energy regulator CNE, 38% of the projects are solar, 27% wind, 21% run-of-the river hydroelectric plants, 10% diesel, 3% geothermal and 1% natural gas. 

The figures include projects up until November 20 last year and roughly 4,000MW of new capacity is expected to come online this year, of which the vast majority are renewable plants.

In December, 28 new energy projects were submitted to environmental evaluation service SEA, including 21 generation projects, three transmission projects and four mining and O&G development projects.

Total installed capacity in the national grid (SEN) reached 23,861MW in December, while total capacity in Chile, including the regional grids of Aysén and Magallanes, was 24,029MW.
