Interview with ees Award finalist
„Electricity can be the major energy to run all known electric applications“ | INTERVIEW with ees Award finalist FENECON GmbH
All our platforms use the FEMS energy management system. As being an energy storage system manufacturer almost mainly means to be a software company, we have quite a lot software architects and developers in our team and we are involved in many research projects with renowned universities and institutes. Together we initiated the OpenEMS energy management system, which is now the leading European EMS software. The code value meanwhile is more than 9 mn USD, which means that anybody developing this himself, would have to invest this sum and several years of time – while OpenEMS is open source and freely available to anybody including hardware manufacturers, utilities or grid operators. For this powerful contribution to a fast and decentral energy transition we were honored with different awards already.
