Quotes: "The successful start of the test is marked by a water vapour column about ten metres high, which has been standing above the plant since Saturday evening next to the B36 near Graben-Neudorf."

"For Deutsche Erdwärme GmbH, operator of the geothermal power plant in Graben-Neudorf, the successful test is a milestone."

"If the locability tests are successful, the next step will be to try to pump some of the water back into the subsurface. For this, however, the operating company needs a further permit from the competent mining office in Freiburg."

"The tests will examine, among other things, whether sufficient water is extracted from a depth of 4,000 meters to achieve the targeted thermal output of 40 megawatts."
