Ideona Delivers Its Second Hybrid Solar Power Plant

The Ideona consulting group has handed over another solar power plant integrated with an electrochemical energy storage system in Söpte, Vas County, according to a statement by Ideona Plc. to MTI.

The energy is produced by 4,123 solar panels with a capacity of 3,300 megawatts per hour, which are capable of meeting the total annual electricity demand of a settlement the size of Söpte, with a population of about 800, the company said.

The HUF 2.3 billion investment was financed from mixed sources, with 60% of the costs secured by a bank loan and the remaining 40% covered by Ideona Plc. The investment was carried out as a project development by Ideona, with WHB ELEKTRO Ltd. acting as the main contractor for the solar power plant and NRG Services Ltd. carrying out the construction. Their first such installation was commissioned last year in Öskün as a result of a research and development project.

Both plants used Vanadium Redox Flow technology, a pioneer on the Hungarian market, for long-term energy storage. The system uses liquid electrolytes that circulate in two separate tanks and store and return energy through chemical reactions. This technology can supply energy for about four times longer than conventional batteries, reduces the risk of fire and explosion in the energy storage because much of it is water, they said.
