The four-year program encompasses approximately 25,000-30,000 network investments and upgrades of varying sizes. New substations, network expansion and digital improvements will increase the electricity grid’s capacity, flexibility and operational reliability.
E.ON said modernizing the network is fundamental to Hungary’s energy transition, electrification and ability to meet rising electricity demand.
The electricity system is changing rapidly. According to the company, the combined installed capacity of industrial and household solar installations and market-based producers in Hungary approached 9,000 MW by mid-2026, representing an almost fortyfold increase over a decade.
The expansion of renewable generation, energy storage, heat pumps, electric vehicle chargers and new industrial investments requires a more flexible electricity network with greater capacity.
Building on HUF 690 bln in Network Investment
E.ON Hungária Group operates Hungary’s largest electricity distribution network, serving Budapest, Pest County and Transdanubia. Since 2022, it has spent approximately HUF 690 bln on energy network investments.
The new program builds on that work, with European Union support allowing development to proceed more quickly, the company said.
Investments will cover E.ON’s entire service area. New substations will be built, while existing facilities will be expanded and modernized, including in the areas around Pécel, Veresegyház and Pilisvörösvár.
The program also includes upgrades to high-, medium- and low-voltage networks, new power supply points, and digital and control-system improvements.
These measures are intended to increase network capacity and flexibility, improve operational reliability, ease local bottlenecks and provide a more dependable electricity supply.
Additional Capacity for Consumers and Producers
The program will create 2,323 MW of additional grid connection capacity by 2030. This represents the network’s ability to accommodate additional connections rather than new electricity generation.
The expanded capacity will allow the grid to safely serve significantly more residential and business customers, industrial investments, and solar and wind power plants simultaneously.
Customers could eventually benefit from faster connections and easier integration of renewable energy producers, alongside stronger security of supply for households and businesses.
E.ON said the investments would provide long-term infrastructure to support Hungary’s energy transition, economic development and investment over the coming decades.
The project, titled “Ensuring a Flexible and Secure Electricity Network to Integrate Weather-Dependent Renewable Energy Sources,” carries the code RRF–GS–6.6.1-26. It is financed partly through EU Recovery and Resilience Facility resources under the Széchenyi Terv Plusz program and partly through E.ON Hungária Group’s own funds.
