The power utility ČEZ has been asked to issue a stance on an accusation by Bulgaria’s antimonopoly office charging the company abused its dominant position on the local market, the company’s spokeswoman Barbora Pulpanová told the Czech News Agency. She stressed that there was no new accusation but that it was related to an inquiry from last March. The spokewoman repeated that ČEZ rejected it as unfounded. Besides ČEZ, Bulgaria's anti-monopoly office on Friday also accused Czech energy company Energo-Pro and Austrian firm EVN of abuse of their dominant position on the market. The companies have been accused of making it difficult for corporate clients to switch electricity supplier or buy electricity on the free market.
