Reuters News reported the Czech government agreed to sell their majority share stakes in two coal operators last week.
The two separate companies to be sold seperately include Severoceske, who supply a major Czech power producer, and Sokolovska.
Rules of the tender state the bidders have at least five-year experience in exploration, keep coal production going for at least 15 years and hold their stake in the operations for 10 years.
Reuters said energy firms operating oil and natural gas assets will not be allowed to enter the tender, which ruled out prospective German bidders E.ON and RWE. No minimum price has been set for the assets.
