The energy industry is on the move: Traditional electricity suppliers are looking for new business models and try to maintain their market position. On the other hand, new providers are edging into the market that have focused themselves on renewable energies, such as wind, solar or biogas. It shows that a consolidation of the market takes place between the providers as the feed-in tariff is decreasing and competition is growing. On the one hand, economies of scale effects and learning curve effects in the production of solar plants, wind power stations and biogas plants lead to less start-up investments while, on the other hand, the growing competition for resources (biomass) and sites (wind use, solar irradiation) causes increasing costs. Therefore, survival in this consolidation phase requires long-term oriented financing, securing of the terms and conditions of sales and purchases and an optimisation of the cost structure.
