Top energy and fuel supply
Oest supplies commercial customers with the entire range of modern heating and fuels. Natural gas, electricity and green electricity can also be purchased directly from Oest by private households. As one of the major shareholders of AVIA Deutschland, Oest has been involved in the continuous expansion of its own wind farms and climate-neutral energy from hydropower for many years.
Research into synthetic fuels and e-fuels also enjoys high priority in the company. In addition to all classic fuels, Oest already supplies synthetic fuels based on HVO (Hydrotreated Vegetable Oils), GTL (Gas-to-Liquid) and regenerative R33 Blue diesel with significantly reduced CO2 emissions.
