Few electricity providers meet sustainability criteria
A new comparison reveals that only a small fraction of electricity providers meet strict sustainability requirements. Four key criteria help consumers distinguish genuine green offers from marketing claims.
A mere handful of electricity providers in Germany fully meet sustainability criteria, according to a new comparison. The analysis, which focuses on four key factors – certification, pricing model, proof of origin, and company transparency – shows that most offers marketed as "eco-power" do not adhere to independent standards.
The term "eco-power" is not legally protected in Germany, allowing any provider to use it regardless of its actual contribution to the energy transition. Marketing terms like "green," "carbon-neutral," or "sustainable" alone do not guarantee that a tariff meets stringent sustainability requirements. This necessitates a systematic verification of underlying criteria, rather than relying on providers' claims.
Regarding certification, recognized eco-labels like ok-power and Grüner Strom-Label are crucial. Both require 100 percent renewable generation and an independently verified contribution to the energy transition, with annual checks. The ok-power-plus level is awarded to providers who certify their entire electricity sales volume.
The pricing model analysis involves comparing the price per kilowatt-hour, the monthly base fee, the minimum contract duration, and the notice period. A fixed-price tariff without price adjustment clauses offers the most planning security. The absence of mandatory advance payments, minimum purchase quantities, or bundled sales also indirectly indicates a provider's adherence to sustainability prerequisites.
Proof of origin (Herkunftsnachweis) is mandatory for all eco-power sold in Germany, but it does not alone confirm if the electricity comes from new installations or if the provider makes an additional contribution. Consumers are advised to directly inquire with providers about the specific origin of the electricity and any additional contributions made beyond certificate procurement. Company transparency, including a clear corporate structure, publicly accessible sustainability reports, and independent evaluations, is also a key indicator.
