Whether in the automotive industry, wind energy business, aerospace sector or in everyday use, components made of hardened steel are needed in many areas. As a leading service provider in the field of hardening and surface technology, the HÄRTHA GROUP improves the load capacity, wear properties and other characteristics of various components. The finishing processes used here are generally very energy-intensive.North Rhine-Westphalia based HÄRTHA GROUP has been purchasing part of the energy required for this purpose from EnBW’s Maßbach solar park since 1 October 2022. To this end, HÄRTHA and EnBW have signed a 15-year corporate power purchase agreement for the supply of 10 megawatts of solar energy.EnBW commissioned the 28-megawatt solar park in Bavaria one year ago. The company realized around two thirds of this, 18.3 megawatts, without funding under the Renewable Energies Act. The HÄRTHA GROUP GmbH secured part of this solar energy, which is freely available on the market.The HÄRTHA GROUP is a successful group of companies founded in 1990.
