* Billionaire Tykac gains full control of Czech Coal
* Czech Coal in dispute with CEZ over supplies
(Adds details, background)
PRAGUE, Dec 17 (Reuters) - Privately-owned investment company Indoverse became the sole owner of Czech Coal, the second largest Czech lignite miner and a supplier for power Group CEZ.
Indoverse, controlled by Czech investor and billionaire Pavel Tykac, held a 50 percent stake in the coal company before saying on Friday it had bought the remaining 50 percent from two other shareholders, Petr Pudil and Vasil Bobela.
The value of the transaction was not disclosed but media reports, which earlier in the weak said the transaction was in the pipeline, estimated the deal could be worth more than 10 billion crowns ($528.8 million).
CEZ, which relies on Czech Coal supplies for some of its power plants, is in a dispute with Czech Coal over coal supplies.
CEZ, the largest listed company in central Europe, seeks 10 billion in damages and claims Czech Coal breached an agreement on long-term cooperation, which obstructed CEZ's plans to modernise or replace new units at its Pocerady coal-fired plant in the north of the country by 2016.
Czech Coal, which is also an energy commodities trader, mines 14 million tonnes of lignite yearly and has available reserves of about 365 million tonnes, according the its web site. Its net profit in 2009 was 3.3 billion Czech crowns on revenue of 12 billion crowns.
