We are Ray Energy, supplier of electricity and gas.


Ray Energy began to operate on the energy market in 2016. Since then, it has been supplying electricity and gas to households throughout the Czech Republic.

It is our goal to make the customers satisfied. It is also why we provide support in the area of energy supplies in the English language so that we can help all who prefer communication in English deal with such a basic even if relatively complicated service.

We pride ourselves in a fair approach and simplicity, in particular in that we offer one of the lowest prices on the market and contract for an indefinite term.

Don't worry, we speak English!
