Chile Says No to $8bn Hydroelectric Project in Patagonia

Chilean ministers unanimously voted Tuesday to revoke the environmental permit of the HidroAysen mega-dam in Patagonia, which would have tamed two of the world's wildest rivers and built more than 1,600 kilometers of power lines to supply energy to central Chile.

After a three-hour meeting, the country's ministers of agriculture, energy, mining, economy and health decided to “side with complaints presented by the community” and pull the plug on the hydroelectric project, environment minister Pablo Badenier was quoted as saying by local newspaper La Tercera (in Spanish).

The decision handed a victory to environmentalists who praised it as a landmark moment. The companies behind the project, Spain’s Endesa and Chile’s Colbun have 30 days from the moment they are officially notified of the decision to appeal the ruling, but experts believe it would be a very difficult obstacle to overcome.

"This project has many aspects that were poorly thought out, especially aspects related to local communities," Energy Minister Maximo Pacheco told reporters after the meeting (in Spanish).

Endesa and Colbun can still tweak the project or take its case to courts, which suggest more legal battling over the fate of the controversial project, which has triggered worldwide protests, may still be ahead.

Chile, the world’s top copper producer, suffers from a chronic energy shortfall that has begun affecting the competitiveness of its mining sector and cramping economic growth.

Experts say Chile needs to triple its current 18,000-megawatt capacity in the next 15 years, but the nation lacks domestic oil or natural gas resources. The dams were planned to generate a total of 2,750 megawatts, almost a third of central Chile's current needs, within 12 years.

    Chile may now have a major energy shortfall. But Chile also has what may be the best set of large sites for major solar energy projects on the planet. The Chilean Altiplano, which has plains as high as 18,000 to 20,000 feet (5-6 km) above sea level and is desert to boot (perhaps also having Lithium deposits like Bolivia's for battery storage as we have seen in another of today's articles) gets what may be the largest single density of solar radiation on Earth between it's height and thin atmosphere, lack of clouds to refract solar energy and nearness to the Equator leading to sunlight travelling closer to straight down to the surface, and few if any local communities. And the altiplano is far closer to the copper deposits and their smelters (which are the biggest single users of energy in Chile) than Patagonian hydroelectric sites leading to much less loss of electrical energy in transmission. So maybe Chile has a viable alternative to those hydro plants that may even produce cheaper energy than the hydro power would have. Chile certainly tells us what the best solar power sites look like.
