    BRASILIA, Nov. 11 (Xinhua) -- The Brazilian Ministry of Mines and Energy said on Wednesday that the blackout which affected the country on Tuesday night had been caused by the collapse of three transmission lines carrying power generated by the Itaipu Dam.

    Two of the fallen lines are located between the towns of Ivaipora (Parana) and Itabera (Sao Paulo), and a third one between Tijuco and Itabera Petro (Sao Paulo).

    According to the ministry's executive secretary, Marcio Zimmerman, the transmission lines had fallen due to adverse weather conditions.

    "There is no equipment damage. Very strong winds and heavy rains have concentrated in Itabera," he said.

    Zimmerman said the system is now back to normal operation, while the blackout, which began shortly after 10 p.m. local time (zero hour GMT Wednesday), lasted two hours.

    Through Twitter, the binational power plant of Itaipu, jointly run by Brazil and Paraguay, had previously said it was suspicious that transmission problems between the Brazilian states of Parana and Sao Paulo would cause energy breakdown.

    Itaipu stressed on Twitter that their responsibility is to generate power, not transmission, and that they had registered no problems at their facilities.

    The transmission is controlled by Furnas Central Electric, a Brazilian state company based in Rio de Janeiro, which has a substation in Foz de Iguazu near the plant.
