Special conditions for start-ups

The idea is good, the business plan is complete, and the work can begin, but every young business with innovative ideas starts small. In order to help young businesses in the energy sector get off the ground, OLEC decided at its last general meeting that special conditions are possible as of now. This applies to businesses in their first 3 years of operation. Start-ups need stable networks and partners by their side to promote their ideas and innovations – and thereby the energy revolution.
OLEC is the only cross-technological network that offers everything you need for your start in the world of renewable energies.
