About

Founded in 1999, BLOCH3 is a limited company headquartered in Krumbach, Austria specializing in Wind, Solar, Biogas.

BLOCH3 is an Austrian family-run company that plans, develops and operates wind parks, photovoltaic plants and biogas plants. It traces its origins to the 1999 storm Lothar, which led founder Franz Blochberger to pursue alternative energy, and it was formerly known as the VENTUREAL group. The company focuses on the Austrian home market and sells electricity to local communities through its own Heimwatt tariff. Its biogas plants in Ziersdorf, Retz and Gars am Kamp process biomass and bio-waste into green energy and biomethane, and its projects are developed with attention to nature and local interests. The company also runs a permaculture-based orchard and forestry initiative in Krumbach.
