Germany: Switching to Renewables

Germany Explores Using Train Lines as a Power Grid

04/22/2011 - Germany's increased emphasis on renewable energies requires an all-new power grid. Now, many in Berlin are wondering if the grid powering the country's train system could be used to transport wind power from the north to the south. Some say it could save up to 75 percent of expected costs.

One of the biggest question marks surrounding Germany's now-accelerated plans to dramatically increase its reliance on renewable energies has been the need to modernize its energy grid. Plans call for much of the country's wind power is to come from offshore wind parks in the north in the future, but sufficient high-voltage power lines necessary to deliver that power to the south do not yet exist.

The German Energy Agency anticipates that fully 3,600 kilometers (2,237 miles) of such lines will be required by 2020. So far, a mere 100 kilometers have been installed.

Now, though, an attractive alternative appears to be in the making. According to German Transport Minister Peter Ramsauer, the government in Berlin is looking into the possibility of using the already existing network belonging to Germany's federal railways. Deutsche Bahn's grid of high-voltage power lines, at 7,800 kilometers, is the second largest in the country behind that belonging to energy giant RWE. The network, the government hopes, could be modified to transport energy to the south and plug other holes in the grid.

"A close cooperation with Deutsche Bahn relating to the expansion of the power grid is something that I find attractive," said German Economics Minister Rainer Brüderle. {continued}
