In 2021, limited injections to gas storage led to unacceptably low inventories being in place at the beginning of November. Whilst the European Union and National governments were aware of the limited amount of gas in store, there was little that could be done about it from a legal and regulatory point of view. Most countries carrying significant storage capacity have historically “left it to the market” since the implementation of various gas directives in the 2000s. However, it has become clear that “leaving it to the market” is no longer an option for the EU, with new legislation being rushed through the European parliament to guarantee a minimum fill at Europe’s storage facilities. In this piece we delve deeper into the last provisional political agreement after a trialogue between the Council, European Parliament, and European Commission; and discuss about the key elements of this proposal, their unintended consequences, and commercial considerations of this new legislation.
