  The Greek Energy Forum - GEF

The Greek Energy Forum (Ελληνικό Ενεργειακό Forum) – founded and headquartered in London since 2013 and currently featuring branch offices in BrusselsAthensNicosiaDubai and Washington DC – is an international energy think tank consisting of Greek energy professionals holding international corporate posts, and sharing a common interest in the broader energy industry in Greece and Southeastern Europe. The members of the  Greek Energy Forum hold international corporate posts and their expertise spans across the energy industry spectrum, benefiting the Greek Energy Forum with a multi-disciplinary skill-set and a holistic approach to its field. The main objectives of the Greek Energy Forum are:

–To establish an international platform of ideas and dialogue amongst energy professionals to enable Change in the energy setting of SE Europe/East Med

–To inform investors and public opinion on latest energy developments and “best practice” examples successfully applied abroad respectively

–To propose and communicate energy policy proposals and reforms to governments and decision makers

The Greek Energy Forum holds regular meetings across different international locations in the form of networking events and round-table sessions, panel discussions or presentations, hosting guest speakers who share their views on targeted energy topics and contribute to the open discussion among its members. Additionally, the formation of working groups within its member structure, results in the publication of articles and opinions papers which are published across multiple media platforms. 

Provided the recent and ever progressing developments around energy and hydrocarbons in Greece and Southeastern Europe, the Greek Energy Forum aims at utilising the know-how and invaluable expertise of its members to contribute with innovative proposals and hence catalyse the growth of the energy industry in the region. We welcome all the energy professionals of Hellenic origin that would like to support that cause and who are willing to enhance their network, exchange ideas and promote the development of the energy and hydrocarbons industry in our region.


The Greek Energy Forum, which takes the form a non-for-profit volunteer association registered in Greece, acknowledges the fact that its members are employed by companies and/or organisations that might be market competitors. As a consequence we are serious about preventing anti-competitive conduct in all our activities.

All individuals involved in the Greek Energy Forum - including the Management Committee, Focus Group Heads/Deputy Heads, Steering Committee, as well as standard members - are serving under their personal capacity. The analysis and opinions they express through the Greek Energy Forum are their own and do not reflect the view of their respective employers. 

What is more, we require that our members never discuss the following topics within the Forum:

-Commodity prices/Freight rates/Costs

-Production numbers and production plans

-Industrial capacity or commodity inventories

-Sales/purchase contracts that have not been announced publicly

-Future business plans
