Minister Rene Tammist spent a day in Berlin at the Energy Transition Dialogue, this time focussing on energy markets reforms and supplemental business opportunities. The Minister took part in a panel discussion dedicated to cyber security in the de-centralisation of energy systems, shedding light on Estonia’s experiences and challenges in the digitalisation of the energy system. We exchanged some thoughts on digitalisation, particularly in the field of buildings, with the chairman of the German Energy Agency DENA, Mr Andreas Kuhlmann.
