Greece's privatisation agency TAIPED said on Monday it had extended the deadline for submission of expressions of interest in natural gas grid operator DESFA to August 7.
Greece is seeking a buyer for a 66 percent stake in the grid under a privatisation scheme it has agreed with international lenders.
Monday had been the deadline.
TAIPED said its board decided to postpone the deadline after a request by a potential investor.
Greek authorities relaunched the privatisation process for DESFA after a deal with Azerbaijan's SOCAR fell through in 2016.
That deal collapsed after Athens passed legislation raising DESFA's gas tariffs by a lower amount than SOCAR had expected.
The agency is selling its 31 percent stake in DESFA and Greece's biggest oil refiner, Hellenic Petroleum, is divesting the rest. [Reuters]
