ROCK TUNNELLING | PROJECT - HYDROPOWER CONVERSION


FORBACH HYDRO CONVERSION ADVANCES


In Germany, major underground works are underway at energy utility EnBW’s Forbach hydropower plant to give rapid response pumped storage capability to support the electricity market and grid


The Rudolph Fettweis power plant in Forbach, Baden, Germany, is a hydropower facility of many parts and the complex is being expanded further, with more tunnels and new generation technology. More than 100-years old, the power plant has played


a key role in energy supplies and the economy of the region. The plant owner, EnBW Energie Baden- Wurttemberg, is now stepping up the facility’s pumped storage capability with further tunnels and caverns. The strategy is in response to the growing and varied demands upon the electricity grid.
