About Us
Rabot Energy is an independent supplier of 100 % renewable energy, offering dynamic electricity tariffs to private and business customers. By passing on exchange buying prices to our customers, we can save them up to 35 % on their electricity bills. Electric vehicle owners particularly benefit from our dynamic electricity tariff, as we have developed a smart system that signals the car when to automatically charge during periods of low electricity prices. And this is just the beginning!

Through our provision of 100% renewable energy and comprehensive smart charging and energy management solutions for homes, RABOT Energy actively contributes to increasing the real green power share in Germany's electricity consumption, thus driving the energy transition forward.
