Edison Delmi investors give mandate on stakes-Enia CEO

MILAN, June 19 (Reuters) - The members of Edison (EDN.MI) investor Delmi have mandated advisers to study options on their stakes in the Italian energy company, Enia's (EN.MI) CEO told Reuters on Friday.

Delmi, of which Enia owns 15 percent, holds a 50 percent stake in Edison's biggest shareholder, Transalpina di Energia, while the remainder is held by France's EDF (EDF.PA).

"We Delmi shareholders have given a mandate to a financial adviser and an industrial adviser, Bain Cuneo, to study the situation and have some plans on how to overcome the impasse on Edison," Enia Chief Executive Andrea Viero said.

"We expect proposals before the summer pause," he told Reuters by telephone. "All scenarios are open."

Other Delmi shareholders are Italian regional utility A2A (A2.MI), which holds 51 percent, and smaller utilities Sel and Dolomiti Energia.
