SANTIAGO (AFP) – A $3.2 1000000000 hydroelectric send in Chile -- seen as a key to new utilization in the South dweller nation but questioned for its environmental impact -- faces a key effort this week.

An environmental commission was due to vote weekday on the HidroAysen project, but appeals and challenges are widely expected.

The send would call for the construction of fivesome hydroelectric noesis stations, digit along the Baker River and threesome on the Pascua River, in an area some 1,600 kilometers (1,000 miles southward of Santiago).

A send under consideration for 50 years, it would create 2.7 gigawatts of forcefulness to support foregather Chile's ontogeny forcefulness needs.

Approval by the regional environmental commission is widely expected, but the organisation faces contestant from environmental groups seeking to protect the Patagonia region.

Moreover, the paths utilised for some 2,000 kilometers (1,200 miles) of noesis cables and towers would be subject to further review.

A coalition called "Chilean Patagonia Without Dams" contends the send is not needed and would threaten pristine forests in a region that includes widely admired glaciers and lakes.

The opponents claim that the send would impair wilderness areas of Patagonia, with the high of some 5,900 hectares (14,000 acres). They feature the environmental analyse has been inadequate, and that Chile would do meliorate with inferior damaging forcefulness sources much as solar and wind.

One poll in Apr showed 61 proportionality of Chileans opposed the project, but the association of Chile's Endesa and the land concern Colbun SA has launched its possess public relations effort, claiming the send would be clean, renewable forcefulness that would turn obligation for imported fossil fuels.

Opponents organisation marches against the send and haw enter appeals if it wins approval, a spokesman said.

But President Sebastian Pinera said the country, which is seeing scheme growth estimated at 6.5 proportionality and has had to apportion electricity, has few meliorate alternatives, especially with thermonuclear noesis existence reconsidered in the wake of the hardship in Japan.

"If HidroAysen is authorised it would be 100 proportionality in compliance with environmental legislation," Pinera said over the weekend.

"If we don't hit hydroelectric energy, there will be more coal-fired noesis plants."
