German Green Power Brand Grüüün to Stop Supplying 200,000 Customers

Grüüün, the consumer electricity brand of the Bavarian company Münch Energie, announced on October 9, 2026, that it will stop supplying private households nationwide as of October 31, 2026. The company, based in Rugendorf in the Kulmbach district of Upper Franconia, gave customers roughly three weeks' notice, according to the trade outlet zfk.de and the business newspaper taz.

Around 200,000 households are affected, a figure reported consistently by topagrar.com, Deutsche Wirtschafts Nachrichten, zfk.de and taz. Grüüün had entered the residential electricity market at the end of 2024 and grew quickly by offering long-term price guarantees of up to ten years, sourced, according to the company, from its own renewable energy generation.

Why Grüüün says it is shutting down

According to taz and Deutsche Wirtschafts Nachrichten, Grüüün's management cited 'the current regulatory trend' and planned revisions to Germany's Renewable Energy Act (EEG 2027) together with a package of grid regulations. The company told customers the government is 'turning the energy transition in the wrong direction' and that, under the coming rules, it would never be able to generate the green electricity volumes it had promised under its fixed-price contracts.

Per zfk.de, Grüüün said it held months of talks with government representatives in an attempt to prevent the legislative changes before deciding to exit the consumer market entirely. The EEG 2027 reform and the so-called grid connection package were, as of the announcement, still under parliamentary review and had not been finalized, zfk.de reported.

Not everyone accepts that explanation. Energy broker Vahid Parma, quoted by zfk.de, argued the real cause was a flawed purchasing strategy: anyone promising fixed electricity prices for ten years needs to secure power at fixed costs for an equally long period. Taz reported that competitors in the sector likewise could not identify specific rule changes that would directly block residential electricity retail.

What happens to affected customers

Customers who do not sign a new contract before October 31 will be automatically transferred to their local utility's basic supply (Grundversorgung) starting November 1, a fallback that typically carries higher per-kilowatt-hour prices than a chosen contract, according to topagrar.com and taz. Grüüün itself is recommending customers switch to Naturwerke, a Check24 subsidiary, taz reported.

According to zfk.de, Germany's Federal Network Agency (Bundesnetzagentur) said energy suppliers generally must give three months' notice before fully ceasing operations, though individual contracts can be terminated earlier if the contract allows it; as of the announcement on October 9, no formal cessation notice from Grüüün had been publicly confirmed by the agency.

No insolvency filing reported

None of the sources reviewed reported an insolvency filing by Grüüün or Münch Energie. The company has described the move as a voluntary termination of its national consumer electricity offering rather than a bankruptcy, Deutsche Wirtschafts Nachrichten reported. Münch Energie continues to operate as a renewable energy project developer, according to zfk.de and taz.

Policy background

Taz linked the dispute to a broader standoff between the renewables industry and the federal government. Economy and Energy Minister Katherina Reiche of the CDU has proposed restricting subsidies for renewable generation, prompting an industry protest in Berlin under the slogan 'Expand instead of brake,' according to taz. Germany's state energy ministers had already voiced opposition to related federal plans in May 2026, zfk.de reported.
