This winter season’s Preventive Action Plan for natural gas supply security in Greece is expected to be significantly lower in cost as it will be limited to a basic set of milder precautionary measures, energypress sources have informed.

The Preventive Action Plan will be determined by the outcome of a risk study currently being conducted for the upcoming winter, deputy energy minister Alexandra Sdoukou recently informed.

Though the study’s results are not yet out, it has already become apparent that drastic energy security measures such as those taken for last winter – among them the rental of an additional FSU at the Revythoussa LNG terminal just off Athens – will not be necessary, well-informed sources have contended.

This winter, gas grid operator DESFA, running the Revythoussa LNG terminal, does not intend to hire an additional FSU, which, along with gas-storage facility rentals abroad last winter season by electricity producers operating gas-fueled power stations in Greece, ended up costing 160 million euros.

In the lead-up to last winter, Greece’s gas-fueled electricity producers were required to store natural gas at underground storage units of other EU member states, as domestic gas storage facilities did not suffice to cover precautionary-measure needs.

The country’s electricity producers have, this autumn, remained far more subdued on gas-storage action at facilities in fellow EU member states. Some of Greece’s major electricity producers have reached agreements to use gas storage facilities, primarily in Italy, if needed, sources informed.

Gas amounts involved in these agreements are believed to be well below levels foreseen by EU regulations and RAAEY, the the Regulatory Authority for Waste, Energy and Water.

Last winter, RAAEY, aligning itself with EU Regulations, which require all member states to store gas amounts equivalent to 15 percent of national annual consumption, set a 7.5 TWh storage requirement.

Market officials have expressed concerns as to whether this requirement still needs to be maintained, noting the Revythoussa LNG terminal could cover extraordinary needs through additional LNG shipments.
