MEKH said the European Union Agency for the Cooperation of Energy Regulators (ACER) and the Council for European Energy Regulators (CEER) have proposed tying mandatory gas storage levels to demand, not capacity, affirming MEKH's own position.

The proposal prevents countries with big gas storage capacity, such as Hungary, from shouldering disproportionate costs, MEKH deputy chairman Pál Ságvári said.

The European Commission earlier proposed raising EU gas storage volume to 80% of capacity in 2022 and 90% thereafter in the interest of boosting security of supply.
