Pfalz, Germany, will receive approval for its special operating plan for "the construction and upgrade for the facilities of the geothermal power plant Landau for the production of geothermal energy" this month according to a release by the responsible regulator, the Rheinland-Pfalz state authority for geology and mining (LGB)

The special operating plan documents the extensive refurbishment work, particularly on the injection well as well as the plant's newly installed safety systems. As a result of these improvements individual tests of the plant's components and a trial operation of the entire plant will be conducted to check the installed safety technology in coordination with the LGB and the Structure and Approval Management South authority (SGD).
