Manolis Panagiotakis has been CEO of PPC since 2015 and his term, which ended in April, has been extended until a shareholders meeting due to take place on June 7.

PPC said on Monday that Panagiotakis was the sole nomination for the post.

The country's state assets fund - Hellenic Corporation of Assets and Participations, is in charge of nominating PPC's CEO as the state holds a 51 percent stake in the utility.

Panagiotakis, a mechanical engineer, has held several senior posts at PPC in the last 20 years and had a key role in concluding the spin-off of the country's power grid last year, a condition of Greece's latest international bailout.

PPC has also launched a series of payment schemes in a bid to collect bills of more than 2.5 billion euros (2.19 billion pounds) left unpaid by Greeks hit by years of austerity and a protracted recession.
