Brazil finally entered the solar power sector on Friday, granting contracts for the construction of 31 solar parks as it tries to diversify its sources of generation amid an energy crisis caused by the worst drought in eight decades.

 

Brazil's energy regulator, Aneel, concluded its first exclusive solar power auction on Friday, clinching 20-year energy supply contracts with companies that will invest 4.14 billion reais ($1.67 billion) and start to feed the national grid in 2017.

 

The 31 solar parks, the first large-scale solar projects to be constructed in Brazil, will have a combined installed capacity of 1,048 megawatts (MW). Market expectations were for projected total awards of 500 MW.

 

The auction lasted more than eight hours. The final price for solar power came at around 220 reais ($89) per megawatt-hour, against an initial price of 262 reais ($106), an 18 percent discount.

 

"This is one of the lowest prices for solar energy in the world," Mauricio Tolmasquim, head of the government's energy research company, EPE said.

 

According to Tolmasquim, costs were reduced because of the strong solar radiation factor in Brazil and because many solar parks would be installed in areas that already have wind farms, reducing the amount developers would spend on land and transmission lines.

 

The government allocated a specific amount of energy to be produced by solar parks, trying to spur development of a local industry and in the long term reduce costs for projects, as it did with wind power some years ago.

 

Brazil's power system has traditionally been composed by a network of large hydro power plants, but almost three years of well below-average rains have depleted reservoirs and sent the country scrambling to diversify its energy matrix.
