Approximately 97% of San Juan’s surface is covered by desert and mountains relying on scant precipitation; water in the province is mostly limited to what results from snow melt high up in the Andes. As such, sustaining an ever-growing population, agricultural activities, as well as local and rural industries have long made the storage, care and rationing of water in San Juan an important issue.
For more than ten years, San Juan has given priority to renewable energies, given in part by the need to store water for the aforementioned residential, agricultural and industrial sectors; and to furthermore generate hydropower that will help reduce the province’s energy dependence on other regions.
This project over the San Juan river adds itself alongside that of Quebrada de Ullum and Los Caracoles, with the end goal being to store water for everyday use and generate hydropower.
El Tambolar is a project containing a certain degree of advanced design, as well as the prospect of regulating the San Juan river while simultaneously converting energy from it.
Located on the La Palca river in the northeastern provincial department of Iglesia, this project is made attractive due to the intense mining activities found in the province, as it will place a standalone energy source near several major mining activities
At the toe of the Cuesta del Viento Dam lies the power plant owing to the same name. In June, 2007, repair work on the dam was finished and the power plant became active, remaining in production to this day
The reservoir dam Quebrada de Ullum was inaugurated in December of 1980, and the hydropower plant initially became active in August of 1989. This complex regulates the San Juan river, a water source vital to the local economy
The primary goals for this project are economic and social development for the province of San Juan, sustainability for irrigation and drainage systems in Valles de Tulúm and Ullúm-Zonda, and sustainability for the national power grid
