German Regulator Probes grüüün’s Planned End to Nationwide Household Power Sales

Germany’s Federal Network Agency (BNetzA) opened an inquiry Oct. 20 into Münch Energie GmbH & Co. KG as its grüüün brand prepares to end its nationwide household electricity offering Oct. 31.

The proceeding examines whether the company gave the required advance notice and whether its customer communications met legal transparency requirements. BNetzA had received no notice of the planned end by Oct. 20. German rules require suppliers to notify the agency at least three months before ending operations. The inquiry has not established a violation.

The plan concerns grüüün’s nationwide household offering. Grüüün had 200,000 electricity customers on June 30, 2026. That June figure does not show how many customers the October plan affects. Customers who do not choose a new supplier will continue receiving electricity through Germany’s default supply system.

Separately, homee GmbH’s stromee brand has arranged to transfer some electricity and gas contracts to SWK ENERGIE GmbH. The transferred contracts cover a low five-digit number of customers. Other stromee customers were offered new SWK contracts; the transfer described covers only part of stromee’s portfolio.

Wholesale electricity prices provide market context but do not establish why either company made its plans. The Germany-Luxembourg day-ahead price averaged €95.21 per megawatt-hour in the second quarter of 2026, up 36.5% from €69.73 in the second quarter of 2025.
