Denne uformelle koordination viste sig dog at være utilstrækkelig til at imødegå de alvorlige forsinkelser, der er opstået hidtil. Interesserne hos gasvirksomheder i forskellige lande og den fordelagtige stilling, som mange gasforsyningsvirksomheder fortsat nyder godt af, skabte faktisk stor usikkerhed om, hvorvidt det var muligt at gennemføre det indre marked inden for gasforsyningssektoren.
Nevertheless, this informal coordination has proved to be inadequate to address the severe delays which have built up until now; indeed, the interests in undertakings of various countries and the privileges of position which many gas supply undertakings continue to gain from, have seriously jeopardised the possibility of completing a single market in the gas supply sector.
