Having spent heavily to make the world's third-biggest hydroelectric project greener, Brazil risks getting a poor return on its $14 billion investment
THE biggest building site in Brazil is neither in the concrete jungle of São Paulo nor in beachside Rio de Janeiro, which is being revamped to host the 2016 Olympics. It lies 3,000km (1,900 miles) north in the state of Pará, deep in the Amazon basin. Some 20,000 labourers are working around the clock at Belo Monte on the Xingu river, the biggest hydropower plant under construction anywhere. When complete, its installed capacity, or theoretical maximum output, of 11,233MW will make it the world's third-largest, behind China's Three Gorges and Itaipu, on the border between Brazil and Paraguay.
Everything about Belo Monte is outsized, from the budget (28.9 billion reais, or $14.4 billion), to the earthworks—a Panama Canal-worth of soil and rock is being excavated—to the controversy surrounding it. In 2008 a public hearing in Altamira, the nearest town, saw a government engineer cut with a machete. In 2010 court orders threatened to stop the auction for the project. The private-sector bidders pulled out a week before. When officials from Norte Energia, the winning consortium of state-controlled firms and pension funds, left the auction room, they were greeted by protesters—and three tonnes of pig muck.
Since then construction has twice been halted briefly by legal challenges. Greens and Amerindians often stage protests. Xingu Vivo ("Living Xingu"), an anti-Belo Monte campaign group, displays notes from supporters all over the world in its Altamira office. James Cameron, a Hollywood film-maker, has chimed in to compare Brazil's dam-builders to the villains in "Avatar", one of his blockbusters.
But visit the site and Belo Monte now looks both unstoppable and much less damaging to the environment than some of its foes claim. The project has made it through Brazil's labyrinth of planning and environmental rules. Norte Energia has hired a second consortium comprising a roll-call of Brazil's big construction companies, which expects to finish work by 2019. Protected by a temporary cofferdam holding back the river's flow, labourers are digging a 20km canal to funnel water from the river to the site of the main power plant, where dozens of excavators are digging down through 70 metres of rock.

The appeal of hydropower
With tens of millions of its citizens moving out of poverty, Brazil can satisfy demand only if it adds around 6,000MW each year for the next decade to its installed generating capacity of 121,000MW. It has plenty of choices. Apart from huge deposits of offshore oil and gas, Brazil has the world's third-biggest hydropower potential (behind China and Russia), and its potential for solar and wind energy is probably among the three biggest, too. The world's largest sugarcane crop provides bagasse, a fibrous residue which burns in high-pressure boilers. The country may also have shale gas. "Brazil is very lucky: it has many choices about how to expand its electricity supply," says Claudio Sales of Acende Brasil, an energy-research institute. "But they are choices, and they need to be made."
These choices will be watched closely elsewhere. In half a dozen other South American countries Brazil is planning joint dams or offering financing for hydropower projects. Countries in Africa and Asia are also looking to hydropower. Lenders such as the World Bank are once again keen.
Brazil's energy ministry has ranked the various sources of energy according to availability, cheapness, renewability and whether Brazil has the necessary technology, says Altino Ventura, its secretary of planning and development. Hydropower comes top, followed by windpower and biomass (mostly bagasse). To spread risks, it decided to generate 50% of new supply from hydropower, 30% from wind and biomass, and most of the rest from gas.
