Ok-power is a quality seal for renewable electricity products managed by the independent nonprofit organization EnergieVision e.V., established in 2000. The seal certifies electricity tariffs that source 100% from renewable energy and demonstrate measurable contribution to the energy transition. Certification requires strict transparency criteria reviewed annually, covering renewable energy sources including solar, wind, hydro, geothermal, biogas, and biomass. The scheme enforces consumer protections prohibiting advance payments, minimum purchase volumes, and unfair contract terms. Certified providers must either source at least 33% of supply from newly developed renewable installations or demonstrate exceptional engagement in project development, financing, and operation of new renewable facilities. A funding contribution of 0.3 cent per kilowatt-hour supports innovative projects advancing energy transition. The organization is jointly supported by Öko-Institut and HIR Hamburg Institut Research.
