In a statement, made at the request of the Portuguese market authority CMVM, Engie said it "has not taken any decision in relation to EDPR and currently is not preparing the launching of any takeover bid over shares issued by EDP Renováveis".
However, the firm added: "As one of the major European utility companies with worldwide operations, we are constantly assessing investment opportunities".
The statement follows EDP’s denial of contact with Engie on 10 April.
Currently, EDP is considering an offer from China Three Gorges (CTG) to takeover the energy firm.
In May, Chinese state-owned electricity company CTG announced a €3.26/share offer to acquire 100% of the Portuguese generator, in which it is the largest shareholder with a 23.27% stake.
The offer, CTG said, represented a 10% premium on EDP shares’ six-month volume-weighted average price, valued EDP at over €11.8 billion.
CTG simultaneously published a €7.33/share offer for the 82.6% stake EDP has in its renewables subsidiary, EDP Renováveis.
The company has been the subject of regular takeover speculation in recent months, with both Spain’s Gas Natural and Italy’s Enel rumoured to have made separate approaches.
EDPR and Engie are currently partners in the Moray Offshore Renewables consortium developing the 950MW Moray East offshore wind project off eastern Scotland.
