Domestic Gas Consumption on Rise in Greece During Q1-2025

Underlining the key role of natural gas in Greece’s energy transformation, domestic gas consumption has significantly increased in the first quarter of 2025 compared with last year, the country’s gas transmission system operator DESFA said.

DESFA’s data said that between Specifically, January and February this year, total gas demand increased by 35.07%, reaching 22.30 terawatt hours (TWh), up from 16.51 TWh in the same period last year.

Following the 30.03% y-o-y growth recorded in 2024, domestic demand for natural gas strengthened significantly in Q1 of 2025, increasing by 28.61% y-o-y to 20.86 TWh, thus reflecting the decisive contribution of natural gas to meeting the growing energy demand in the country during this period, DESFA said.

In fact, on 24 February 2025, a record high of 357 GWh of natural gas demand was recorded in the country and a rapid increase was also recorded in natural gas exports (+396.55%), which reached 1.44 TWh during this period from 0.29 TWh in the first quarter of 2024.

Regarding the categories of natural gas consumers, electricity producers continue to represent the largest consumption, covering 64% of domestic demand. Compared with the previous year, demand from power producers increased by 48.11%, reaching 13.33 TWh from nine TWh.

On the contrary, a decrease of 14.80%, compared to the first quarter of 2024, was recorded in the consumption of natural gas by the industries and CNG fuelling stations directly connected to the NNGS, reaching 2.13 TWh, a quantity that corresponds to almost 10% of domestic demand. Consumption from the distribution networks in the first quarter of 2025 reached the level of 5.40 TWh, increased by 14.41% compared to last year, covering 26% of total demand.

The Revithoussa LNG terminal (Agia Triada Entry Point) returned as the main gateway for the country, covering approximately 44.5% of total imports. In particular, in the period January- March 2025, approximately 10.65 TWh of LNG were unloaded by 20 LNG carriers compared with 6.93 TWh by 9 carriers in the corresponding period of the previous year.

US Largest Exporter

The largest percentage of these LNG quantities came from the US, reaching 8.65 TWh, compared with 4.54 TWh in the same period last year. In second place were imports from Nigeria (1.12 TWh), followed by Norway (0.93 TWh). The strategic role of Revithoussa was recently highlighted in the auctions for LNG unloading slots, where almost all slots were sold until 2030.

With regard to other entry points, Sidirokastro was the second gas entry gateway, covering about 38.8% of imports (8.66 TWh), with an increase of 19.45% compared with Q1 of 2024. The Nea Messimvria entry point, through which gas transported via the TAP pipeline is delivered, covered 12.05% of imports (2.69 TWh), while the remaining approximately 4.6% was imported through the Amfitriti entry point (Alexandroupolis FSRU).

Finally, DESFA’s LNG Truck Loading service at Revithoussa has recorded rapid growth, with 144 LNG trucks loaded in Q1, compared to 39 LNG trucks last year, thus transferring approximately 43,5 GWh This 270% increase confirms that the service offers an efficient and flexible solution to meet the energy needs of remote distribution networks and industrial consumers both in Greece and the wider region. DESFA’s infrastructure contributed substantially to the diversification of natural gas supply sources and to the strengthening of the security of supply level both in Greece and in the wider region.

The liberalisation of the energy market and the regulated Third-Party Access TPA, under which DESFA provides access to the NNGS, strengthens competition among natural gas suppliers to the benefit of end consumers. Third Party Access (TPA) is governed by the provisions of European Union and national law, ensuring open access to any interested party.
