Abdelatty reaffirmed Egypt's support for the project, which aims to transmit renewable electricity from Egypt to Greece and onward to other European markets through an undersea power cable.
He added that the grid would strengthen Europe's energy security and deepen the strategic partnership between Cairo and Athens.
Karydas briefed the Egyptian minister on the latest developments of the project's financing and implementation, according to a statement by the Egyptian foreign ministry.
The €3.5 billion GREGY project aims to transmit 3,000 MW of renewable electricity from northern Egypt to Greece via a subsea cable, allowing part of the power to be exported to other European countries.
The project was launched following a 2021 memorandum of understanding between Egypt and Greece to establish an electricity interconnection.
Developed by Greece's Copelouzos Group through its subsidiary ELICA Interconnector, the project has been backed by the European Union as a strategic energy infrastructure project.
During the meeting, Abdelatty also encouraged the Kopelouzos Group to expand its investments in Egypt beyond the GREGY project, particularly in the energy, natural gas, and airport development sectors.
He highlighted investment incentives offered by the Egyptian government as part of its efforts to attract foreign capital.
He also expressed hope that the Greek group would establish an office in Egypt to support broader cooperation in the coming period.
The meeting took place at the start of Abdelatty's visit to Brussels, where he is holding talks with European officials ahead of his participation in the 11th meeting of the Egypt-EU Association Council in Luxembourg on Monday.
