Germany’s natural gas storage facilities surpassed a fill level of more than 75% this month, two weeks ahead of schedule, as Europe’s largest economy scrambles to prepare for the coming winter.

The latest data compiled by industry group Gas Infrastructure Europe shows Germany’s gas storage facilities at slightly over 77% full.

Chancellor Olaf Scholz’s government initially planned for gas storage levels to reach 75% by Sept. 1. The next federally mandated targets are 85% by Oct. 1 and 95% by Nov. 1.

European governments are racing to fill underground storage facilities with natural gas supplies in order to have enough fuel to keep homes warm during the coming months.
