By 2020, 30% of Germany's power will have to be generated from renewable energy sources. In order to obtain this goal and to be able to transport this carbon-free power, the existing electricity transmission grids have to be expanded with society's approval. As a leading transmission system operator, 50Hertz is committed to the total integration of renewables. That is why we have joined organisations throughout Europa to further the expansion of transmission grids to bring about the full and complete integration of renewable energy.Furthermore, 50Hertz has made it its aim to consistently reduce the emission of greenhouse gases produced during grid operation, maintenance or repairs. That is why we support eco-friendly technology and continue to adapt to new developments.
