(Bloomberg) -- Germany’s gas storage facilities have reached a fill level of 75%, two weeks ahead of schedule, the country’s top regulator said, as Europe’s biggest economy tries to shore up supplies cut by Russia.  

“The first stage goal has been reached”, Klaus Mueller, president of the Federal Network Agency, said on Twitter. “Gas storage facilities are 75.43% full, the next target is now 85% by Oct. 1.”

German regulations stipulate that storage facilities must be at least 75% full on Sept. 1, rising to 85% on Oct. 1 and 95% on Nov. 1.
