KG, a subsidiary of the drilling technology and geothermal specialist Daldrup & Söhne AG (ISIN DE0007830572), has started electricity production in Taufkirchen. The first feed-in was preceded by successfully completed system tests of the components of the power generation plant in recent days. This means that, for the first time and in parallel to the district heating supplied to the communities of Taufkirchen and Oberhaching, environmentally friendly electricity generated at the power plant will now be fed into the public grid. With the weather-related decline in district heating production, the power production of the plant is being ramped up further. A further heat exchanger will be connected in the second half of 2018. Thus, from today's perspective electricity production will then gradually switch to full load operation. For the further planning of the 2018 financial year, the management board assumes that corresponding feed-in revenues can be generated from power generation.
