E.ON Hungária has developed the Flex.ON program as part of a tender by the Ministry of Energy to address the challenges of the energy market through the development and integration of smart devices into the grid. Of the HUF 2.1 billion (EUR 5.2 million) development series, 39% was funded by the state, while 61% was financed by E.ON.
The investment aims to meet the growing energy demand of customers and connect more solar power plants to the grid. As part of the three-year R&D program, E.ON has installed around 200 devices in its network, including 19 voltage regulators, 63 smart measurement sensors, the battery energy storage system in Aszófő, 3 low- and medium-voltage transformers, and 100 decentralized battery storage units for households.
Additionally, E.ON is collaborating with eleven private solar power plants to regulate their production in case of grid congestion.
Furthermore, the company has created a unique flexibility platform in Europe for the Transdanubian region, enabling optimal operation of the electricity network.
