A German regulator is examining whether Münch Energie GmbH & Co. KG gave required notice and customer information before ending grüüün’s nationwide household electricity offer Oct. 31.
The Federal Network Agency (BNetzA) opened its inquiry Oct. 20 and said it had received no notice of the plan by then. German rules require power suppliers to alert the agency three months before ending household service. The regulator is also checking whether Münch Energie’s customer information meets legal transparency requirements. It has not found that the company broke the rules.
The plan applies to grüüün’s nationwide household offer, rather than all of Münch Energie’s power activity. The company reported 200,000 electricity customers in Germany on June 30, 2026, but that figure does not establish how many contracts are covered by the Oct. 31 change.
On its website, grüüün tied its decision to proposed measures it calls “Erneuerbare Energien Gesetz 2027” and “Netzpaket 2027.” The company says the proposals would leave planned green power volumes unproduced, a forecast that is unverified. It also said other providers left as regulations changed but gave no examples. That claimed precedent is unverified.
grüüün says customers may accept an offer from Naturwerke or select another supplier. It warned that basic supply may cost more, while each household’s bill impact depends on its chosen tariff. The Oct. 31 announcement does not mean every customer’s existing supply ends that day. Under the Federal Network Agency’s general consumer guidance, a local default provider supplies a household if its existing supply ends before a new supplier takes over. Whether the household enters basic or replacement supply depends on how the current contract ends.
The company said it would prepare final bills in November. It plans to end nationwide household sales Oct. 31; BNetzA has not announced a date for concluding the inquiry.
