The European Public Prosecutor’s Office confirmed to international news agency Reuters that it has opened an inquiry for “possible criminal offences” for the Great Sea Interconnector project (GSI).

“The EPPO can confirm that it has an ongoing investigation,” the agency said in a written response to Reuters. “No further details can be made public at this time, in order not to endanger the outcome of the investigation.”

In Athens, IPTO, the Independent Power Transmission Operator ADMHE , declined to comment, Reuters noted, adding that “a government spokesperson in Greece, which has been actively supporting the project, said Greece had not received any advisory on the probe.”

The Greek operator took over the GSI project in 2023, replacing a Cyprus-based project manager.

Piotr Serafin, the EU budgetary affairs and anti-fraud commissioner in Cyprus, declined to comment on Thursday, citing EPPO’s independence. He said he was not aware of any concerns expressed by his office over the project.

On completion, project promoters say the link would be “the world’s longest” high-voltage cable at 1,240 km (770.5 miles) and also the deepest at 3,000 metres.

The EPPO probe was revealed by Cypriot President Nikos Christodoulides late on Wednesday.
