Poland’s and the Czech Republic’s biggest power groups were among bidders Tuesday for 83% of Energa, the fourth-largest Polish power company, as the government sells utilities to cover its budget deficit. ČEZ is bidding for Energa, Petr Ivánek, the head of ČEZ’s Polish unit, said Tuesday. For investors, Energa is an “almost pure distribution player” that offers “long-term stability” because of its customer base, said Pawel Puchalski, head of equity research at Bank Zachodni WBK Brokerage in Warsaw.
