Natural Gas Supply

DEPA is the main importer of pipeline natural gas and liquefied natural gas (LNG) in Greece. The company’s over15-year experience in the domestic market ensures the optimal coupling between international supply and indigenous demand.

DEPA’s strategic goal is to ensure to its customers sufficient natural gas volumes from reliable and diversified resources in competitive prices, ensuring country’s security of supply. DEPA is the only company in Greece that has signed long term contracts with the Russian Gazprom, the Turkish BOTASand the Algerian Sonatrach.

DEPA’s contract with Gazprom ensures the supply of Greek market up to 2026. The natural gas volumes are injected into the NNGS at Strimnochori Sidirokastrou, near the Greek – Bulgarian borders. The contract with the Turkish BOTAS concerns supply of natural gas up to 2021. Natural gas is injected into the NNGS at Kipoi Evrou, through the existing Interconnector Turkey-Greece.

Likewise, the contract with Sonatrach (LNG) ensures supply of LNG in the Greek market up to 2021. Algerian LNG enters the NNGS at the re-gasification terminal on Revithousa Island, in the gulf of Megara.

Furthermore, DEPA is supplied with LNG from the global spot market, when this will mean better prices for its clients and/or coverage of increased demand.

Finally, DEPA has recently entered into a long term supply contract with the Azeri AGSC for gas to be produced at the Shah Deniz II reserve.

DEPA continuously monitors and evaluates global trends in the natural gas market and is in contact with potential new suppliers, whose own production may contribute to secure supply in the Greek market at competitive prices.

DEPA’s contribution to security of supply


DEPA has long safeguarded the uninterrupted supply of gas to the Greek market through its long-term gas supply contracts, intentional diversification of sources and routes and trustworthy co-operation with some of the largest producers of natural gas in the world.

DEPA monitors and participates actively in the developments of the global gas market, in order to exploit them for the benefit of its customers. In this framework the company is in constant contact with its international suppliers to ensure that the terms of its long-term contracts correspond to its customers’ economic reality, thus supporting actively their sustainability.

Moreover, DEPA is being present in the global spot market, in order to ensure profitability for its clients, and also to ensure the sufficient supply of the Greek market in case of increased demand.

DEPA strives constantly to improve security of supply though diversification of sources and routes of importing gas. Thus DEPA develops significant projects like pipelines like IGI Poseidon (offshore connection between Greece- Italy), IGB (Interconnector Greece-Bulgaria) and East Med (offshore connection of East Mediterranean gas fins with Greece) and a new LNG terminal in Northern Greece. These projects improve the security of supply in Greece and in wider region, in full alignment with European Union directives.


The Portfolio Management, Risk & Commercial Transactions Division is entrusted with the comprehensive management of the gas portfolio and of the operational management risks of DEPA.

A broader objective of the Division is to provide added value to the commercial activities of the company, thus enhancing the returns of the corporate portfolio and minimizing, to the utmost degree possible, risks that may arise from each transaction. Practically, portfolio management contributes to the enhancement of the decision making process in matters of supply, the transport of gas and of commercial transactions.

The utilization of available information and technical forecasts forms a major characteristic of Portfolio Management, with the employment of advanced analytical instruments and assessment, analysis and risk hedge techniques, as to achieve a better return from a widely diversified portfolio.


Natural gas penetration in power generation is accelerating, following the deregulation of electricity and natural gas markets. Natural Gas Combined-Cycle power plants and the Co-generation Systems are the optimal choices both in terms of cost and energy saving and environmental impact.

The Public Power Corporation (PPC) was the first customer of DEPA, as the supply of the first power plant using natural gas took place in Greece in June 1997, at Agios Georgios, Keratsini. Today, natural gas is also used at PPC combined-cycle plants in Lavrio, Komotini, Aliveri and Megalopoli.

During the summer of 2004 the first private open-cycle power plant of 148 MWe (peak unit), owned by HERON THERMOELECTRIC SA was connected to the National Natural Gas Transmission System.

ELPEDISON POWER SA has been operating since May 2005 a Combined Cycle Power Plant of 390 MWe at Echedorou municipality, in the Prefecture of Thessaloniki.

In May 2008, a 334MWe Power Co-generation plant started operating to meet the needs of “ALUMINIUM SA”.

In early 2010, the operation of a combined cycle power plant of “HERON II THERMOELECTRIC STATION VIOTIA SA” with installed power of 435 MWe, started operating using natural gas as a fuel in the area of Thebes in Viotia.

In April 2010, the second combined cycle power plant of ELPEDISON POWER SA came into operation in the Industrial Area of Thisvi, Viotia, with 421.6 MWe installed power.

In November of the same year, the combined cycle power plant “PROTERGIA” started operating in the region of Agios Nikolaos, Viotia, with 444 MWe installed power.

The combined cycle power plant of 436.6 MWe of “KORINTHOS POWER SA” started operating in October 2011 at the area of Agii Theodoroi, in the Prefecture of Korinthia.

The industrial sector includes consumers with an annual consumption equal to or more than 2,200,000 KWh Gross Calorific Value of natural gas (approximately 200,000 Nm3 annually), whose activity is either production or manufacturing.

Natural gas offers industry increased efficiency, with fewer emissions, while a large number of small and large businesses using natural gas can effectively cut operational costs and upgrade their production procedures, eventually leading to improved quality of their final products.

Natural gas can be for thermal or chemical use (as a raw material for the industry), as well as in Co-generation systems, which simultaneously generate usable electric power and thermal energy. The energy generated can be used both for thermal and cooling or air-conditioning needs.

Natural gas is currently used for combined heat and power in industrial sectors, such as food, metallurgy and textiles, in large greenhouses, as well as in major commercial sectors (hospitals, hotels, etc).

Currently, the total industrial use of natural gas in regions where a network is available is around or more than 90%. DEPA has entered into natural gas sales contracts with approximately 150 industrial units, 10 out of which have an annual consumption more than 100 GWh).

Dispersion of Industrial and Commercial Customers of DEPA per region

Natural gas capabilities are apparent in the commercial sector, through the variety of its uses: heating and cooling of spaces to hot water, preparing meals and Combined Heat & Power (CHP).

It is worth noting that today six (6) General Hospitals in Lamia, Serres, Evros, Xanthi, Drama and Thebes and four (4) big hotels in Serres and Alexandroupoli are supplied with natural gas.


The benefits of natural gas, both environmental and economic, are worldwide recognized. According to recent estimations, natural gas vehicles on a global scale are 11.5 million, while in Europe, over 1.5 million vehicles use natural gas.

The European Union proposes governments to offer incentives for natural gas to be used as fuel, to reduce dependence on oil and protect the environment.

DEPA has recently been developing the necessary infrastructure for the refueling of gas-powered vehicles, and today 600 public transportation buses (former ETHEL) (20% of the OASA [Athens Urban Transport Organisation] buses) and 102 municipality garbage collection vehicles use natural gas as fuel.

DEPA has two refueling stations in Attica, in the areas of Anthousa and Ano Liosia. Their capacity reaches 5,000 cubic meters/hour (Nm3/h), ranking them among the largest in Europe. Both, Anthousa and Ano Liosia Stations are operating as retail stations for the refueling of professional and private use vehicles with natural gas or dual fuel motor. Below you can see the price of natural gas which is updated every week.

Retail stations for the refueling of professional and private use vehicles with natural gas or dual fuel motor are operating in Attica: Kifisia (264, Kifisias Avenue); Nea Philadelphia (8th km of Athens – Thessaloniki National Road, direction towards Lamia), in Thessaloniki at Pylaia (128, Georgikis Scholis Avenue) and Nea Magnisia (136, Konstantinou Karamanli Street, Ionia), in Larisa (Volos Street 65) and Volos (Larissa Street 202).

DEPA’s future plans for further penetration of natural gas as a fuel in Greece include the installation of Compressed Natural Gas (CNG) Pumps in Stations in the big cities. Also, there is a collaboration with the Municipality of Thessaloniki to promote the use of natural gas as a fuel for the vehicles in Thessaloniki by entering into a Memorandum of Collaboration signed between the Municipality and DEPA.
