UPDATE 1-CEZ buys stake in Dalkia Czech ops, heating plant

* CEZ gets 15 pct stake in Dalkia's Czech business

* Buys 85 pct in heating subsidiary

(Adds details, shares)

PRAGUE, Nov 9 (Reuters) - Czech power group CEZ (CEZPsp.PR) signed a deal to buy a stake in Dalkia's Czech operations in one of the biggest power deals in the country this decade.

Under the deal, CEZ will get a 15 percent stake in Dalkia's Czech subsidiary for 3.6 billion crowns ($210.2 million), CEZ said on Monday.

It will also buy an 85 percent stake in a Dalkia heating company in the north of the country for an undisclosed amount, although it said the plant was valued at 6.3 billion crowns.

CEZ will have an option on the remaining shares of the heating company, while Dalkia, a joint venture of France's EDF (EDF.PA) and Veolia (VIE.PA), also has a right to buy back the 85 percent stake.

Shares in CEZ, central Europe's largest listed company, rose 0.7 percent to 900 crowns by 0902 GMT, underperforming a 1.7 percent rise in Prague's main index .PX.

The deal, which still must go through competition regulators, confirms an earlier media report that valued the entire transaction at 9 billion crowns. [ID:nL9352075]
