- Increase in domestic natural gas consumption by 28.61% compared to the corresponding period last year, with natural gas steadily strengthening its role in the energy mix.
- Power generation leads the country’s gas consumption surge with a 48.11% year-on-year increase, accounting for 64% of domestic demand.
- Revithoussa plays a key role in the country’s energy system with more than doubling of cargoes compared to the first quarter of 2024 and dominance of LNG that covered about 44% of total imports, with the U.S. as the main supplier.
- Rapid growth for the LNG Truck Loading service, with the loading of 144 LNG trucks at Revithoussa in Q1 2025, offering an efficient and flexible solution for supplying remote users.
- Increase in gas exports through strengthened interconnections with the regional energy market.
According to DESFA’s data for the first quarter of 2025, domestic gas consumption is significantly increased compared to last year, underlining once again the key role of natural gas in the country’s energy transformation, allowing the safe integration of RES and contributing to the export character of the system in a flexible and reliable way.
Specifically, during the period of January – March 2025, 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% year-on-year growth recorded in 2024, domestic demand for natural gas strengthened significantly in Q1 2025, increasing by 28.61% year-on-year to 20.86 TWh. This development reflects the decisive contribution of natural gas to meeting the growing energy demand in the country in this period. It is reminded that, on 24 February 2025, a record high of 357 GWh of natural gas demand in Greece was recorded. 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 to the previous year, demand from power producers increased by 48.11%, reaching 13.33 TWh from 9.00 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 fueling 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.
LNG continues to play a leading role in gas imports. 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 to approximately 6.93 TWh by 9 carriers in the corresponding period of the previous year. The largest percentage of these LNG quantities came from the USA, reaching 8.65 TWh, compared to 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.
In terms of the contribution of the other entry points, Sidirokastro was the second gas entry gateway in the country, covering about 38.8% of imports (8.66 TWh), with an increase of 19.45% compared to Q1 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 liberalization 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.
