Top energy and fuel supply

Oest supplies commercial customers with the entire range of modern heating and motor fuels. Private households can also purchase natural gas, electricity and green electricity directly from Oest. As one of the major shareholders of AVIA Deutschland, Oest has been involved in the continuous expansion of its own wind farms and climate-friendly energy from hydropower for many years.

Research into synthetic fuels and e-fuels is also a high priority for the company. In addition to all conventional fuels, Oest already supplies synthetic fuels based on HVO (Hydrotreated Vegetable Oils), GTL (Gas-to-Liquid) and regenerative blue diesel with significantly reduced CO2 emissions.
