Background

In April 2022, Elpedison announced it was planning to install a floating storage and regasification unit (FSRU) offshore of Thessaloniki, and had submitted an application for a new independent natural gas system (INGS) license to Greece’s Regulatory Authority for Energy (RAE). The Thessaloniki FSRU would connect to onshore and underwater pipelines with Elpedison’s power plants in Thessaloniki, one existing and one under design, as well as with existing pipelines in the area. Elpedison said it was targeting a 2025 start date, subject to approvals and a final investment decision, and the FSRU would be able to deliver up to 20 million cubic meters per day, which equates to 7.3 bcm/y.

In December 2023, Elpedison tested market interest for the project, inviting parties to express interest in booking capacities and services from the terminal. Members of environmental organizations and scientists expressed concerns over the project's environmental impacts at an event in Thessaloniki in May 2025.

Ownership

Greece's energy regulator RAAEY published a notice in April 2026 that Enerwave AE (formerly Elpedison AE) had requested a modification of the project's Independent Natural Gas System (ASFA) license — specifically covering the change in company name and the change in its shareholder composition. The new company name was defined as "Enerwave S.A." with the distinctive title "Enerwave AE", while its shareholding structure is as follows: HELLENiQ ENERGY INTERNATIONAL GmbH ( headquarters Austria) - 45% and HELLENiQ ENERGY Holdings AE - 55%.

FSRU and Related Infrastructure

The company, based on the design, will develop the floating station with two ships, one for gas storage only (FSU) and one for storage and regasification (FSRU) that will have a total capacity of 270-280,000 cubic meters of LNG. The floating dock will consist of two ships moored to an artificial island, on an area of ​​approximately 80 acres (395 m X 204 m). It will be located 3.45 kilometers south-southwest of Pier 6 of the Port of Thessaloniki and approximately 3.12 kilometers east of the nearest western coastline. The liquefied natural gas will be brought to a temperature of -160 degrees Celsius and will be gasified using warmer seawater. The gasified natural gas will then be transported via a long submarine pipeline to land and via an onshore pipeline to Elpedison's facilities in Diavata, while quantities will also be channeled to the NNGS (National Gas Transmission System). The terminal will have a nominal LNG gasification capacity of 6,378 MWh/h (5.16 bcm/year) and a maximum capacity of 9,567 MWh/h (7.74 bcm/year).

Recent Developments

As of July 2026, the Thessaloniki FSRU project is approaching a decisive juncture, with parent company HELLENiQ Energy was expected to make a final investment decision — estimated at around EUR 150 million — within the first half of 2026. According to Enerwave's own timeline, as published on DESFA's website, the project's environmental licensing process is expected to conclude by April 2026, followed by a market test in July 2026 to gauge commercial demand and help determine whether the investment ultimately proceeds. If the project moves forward, the FSRU would enter trial operation in November 2028, with commercial operations beginning in January 2029.
