Sustainability: CNN Chooses Ollagüe

Published on Monday, 15 June 2015

The full-round sustainability that characterises the Ollagüe project starts from electricity generation, involves distribution grids and ends up with consumer relations. In fact, in the Chilean town EGP is completing a wide-ranging hybridisation technological formula, by means of renewable energy plants (small wind and solar PV) that will be combined to the existing cogeneration system and integrated into an autonomous and self-sufficient network thanks to storage devices that complete and smarten up the project.

EGP’s project fulfils a dream of the local population that up to now has lacked stable and constant access to electricity, having to rely on a diesel generator. Thanks to the integration of renewable plants into a cogeneration system, the project will attain an installed capacity of 232 kW and will generate around 460 MWh per year, making energy available around-the-clock for the inhabitants of the Chilean township. Renewable sources will meet consumption needs 85 percent of the time, thus limiting the use of the existing generator only to specific cases and during the winter.

Ollagüe is an innovation laboratory at different levels: on the one hand it enables the testing of the performance of various materials and technologies at high altitudes and with strong temperature fluctuations and on the other it offers a unique reference for assessing the performance of the technological mix that has been used to meet the needs of isolated communities lacking access to electricity.
