German utility RWE has submitted a bid for a 67 percent stake in Polish peer Enea, German paper Financial Times Deutschland reported, citing unidentified people in the financial industry.

A spokesman for RWE declined to comment.

The Polish treasury ministry said on Friday Poland received two bids from unnamed entities for the 67 percent stake it still holds in Enea, the country's only listed utility.

Sweden's Vattenfall VATN.UL, which already owns 19 percent of Enea, was seen as the most likely company to acquire the stake, worth some $2.3 billion, but said on Friday it dropped out of the race, as did Czech utility CEZ.

France's GDF Suez had also shown interest.

Poland floated a 23.5 percent stake in Enea last year, with Vattenfall acquiring 19 percent for 1.7 billion zlotys ($588.2 million), but received little interest from others.
