E.ON brings its second large-scale mobile energy storage to Hungary

E.ON switched its second large-scale mobile and flexible battery storage system to the distribution grid in Hungary. With the help of the energy storage system more renewable energy can be connected to the grid faster and in a more affordable way.

The mobile energy storage systems were designed to tackle local challenges in the distribution grids, reduce grid overloads, promote decentralised generation, increase flexibility in the networks and eventually enable energy communities.

It’s an interim solution for local hotspots where new renewable plants, exceed the currently available connection capacities. The storage system ensures that energy from renewable sources can be flexibly aligned with consumer needs.

The mobile storage system is located in the village of Duzs and is expected to help for the further expansion of green energy in the region which offers great conditions for photovoltaics but the installation of more solar plants has slowed down due to insufficient grid capacities. Two large solar parks already in operation are located close to E.ON’s storage system.

“The expansion of renewables is a fundamental prerequisite for Europe to achieve its climate targets,” said Mark Ritzmann, Managing Director at E.ON Innovation. “Within the next decade, renewable energy capacities will grow as never before. However, existing networks have not been designed to meet these challenges when they were built. To bridge this gap, smart technologies for short-term flexibility are needed. In this respect, Dúzs and the other IElectrix sites, with their mobile storage units and use of digital technology, are real showcase projects for a sustainable energy future.”

This is the third storage system of this kind connected by E.ON to the grid following one in Mecklenburg-Western Pomerania, Germany and another one in Zanka, Western Hungary.

“The total installed capacity of solar power plants connected to the grid has increased 20-fold in the last four years in E.ON’s service area in Hungary alone,” added Attila Kiss, CEO of E.ON in Hungary. “In the future, new capacity will be created in many places. “With our solutions, we want to help households and businesses benefit from this development and use local green power where it is generated. This strengthens local value creation and makes the switch to renewables more attractive.”

The installed battery energy storage systems are two demo-sites of the project HELGA (Hungarian Energy Storage: Local Communities for Global Advantage) with a total budget of approximately 3.6 million euros. HELGA has been implemented as part of the EU-supported IElectrix program.
