The consortium, called Sao Paulo Energia, will pay 14.6 reais per Cesp share, a 2.09 percent premium over the minimum sale price at the auction. Considering Sao Paulo's government stake of 40.6 percent, the consortium will pay a total of 1.7 billion reais ($458.25 million).

Shares of Cesp, or Companhia Energética de Sao Paulo SA, rose more than 12 percent after the auction to 17.07 reais each.

The consortium was the only bidder at the auction, which ends a privatization process that started last year and faced postponements due to legal disputes.

CPPIB and Votorantim Energia already have a joint venture in Brazil that plans invest in renewable power sources.
