Gas grid operator DESFA’s annual gas auctions, taking place today to offer capacities at the grid’s entry and exit points, will play a pivotal role in clarifying and determining to what extent Greece could reduce gas quantities that will need to be stored away at Italian and Bulgarian facilities between November and March for energy security next winter.

The outcome of the auctions will shape Greece’s negotiating position in talks with the European Commission for the country’s gas storage needs.

If the vacant grid capacity left over from today’s auction process is small, then Greece will seek a smaller gas-storage requirement from Brussels authorities.

Greece’s gas storage requirement last winter was limited to 1.14 TWh, based on the country’s vacant capacity at the Nea Mesimvria grid entry point, in the north.

An exception offered by the European Commission to EU member states with a shortage of gas storage facilities, such as Greece, enables storage requirements to be kept at 15 percent of the average consumption level over the past five years.
