Transformer Upgrade by E.ON Enhances Hungary’s Grid Reliability
E.ON Hungária Group has inaugurated a new HUF 2.2 billion (USD 6.5 million) remote-controlled transformer substation in Veszprémvarsány, designed to modernize the region's power grid and support increased renewable energy integration.
The fully automated 132/22 kV facility replaces an older 35/22 kV switching station, boosting capacity and operational efficiency. Described as upgrading from a "single-lane access road to a multi-lane highway," the station supports stable service for up to 16,000 households and enables the integration of 1,000 solar systems.
"This investment strengthens both residential and industrial energy supply while paving the way for future green energy connections," said Balázs Lehoczki, CEO of E.ON Észak-Dunántúli Ãramhálózati Zrt.
Part of the Danube InGrid cross-border EU-supported project, the station is among 12 being built or expanded across Hungary. It connects to a 64-km 132 kV transmission line linking Kisbér, Zirc, and Litér. Two-thirds of the funding came from E.ON's own resources, with one-third from the European Union.
Márk Alföldy-Boruss, Deputy State Secretary for Energy Policy, highlighted the development's role in achieving energy sovereignty and carbon neutrality, calling it a step toward a cleaner, smarter energy economy.
The substation is expected to help attract energy-intensive industries and reduce downtime by enabling faster fault detection and remote management.
