Bulgarian Socialist Party (BSP) will bring to the prosecutor the deal with the US investor AES, for TPP Maritza-East 1. Last week the Cabinet approved the finalization of the deals for TPPs Maritsa-East 1 and 3 with US companies Entergy and AES. The contracts will be signed soon; the investment amount expected is $1,4 Bln. BSP claims against the `darkness` and lack of transparency in the deal, high electricity prices (AES will sell electricity initially on $0,044), 12% suspected offshore capital in AES, that is $120,000. King`s party also appealed to the Kostov`s government not to signed the contracts before the General Election June 17, because the deals are disadvantageous for both parties.
