Grid reinforcement east

Initial information sessions for property owners in the project area

The Netzverstärkung Ost project, one of APG’s largest and most important current initiatives, was presented for the first time in May 2026 to affected property owners in the host communities in Lower Austria and Burgenland. On Monday, May 11, the first information session with property owners took place in the municipalities where the Netzverstärkung Ost project is located. The sessions began in the municipalities of Münchendorf and Moosbrunn in Lower Austria, followed by Himberg on May 12. In total, over 30 sessions were subsequently scheduled in 14 municipalities.

During these sessions, the project team explained the project, addressed the individual situations of the property owners, and answered specific questions. The focus was on open dialogue and active exchange on an equal footing. In Burgenland, Netz BURGENLAND is a project partner and was present at the information events in Parndorf and Neusiedl. The next step in public relations will take place in September 2026 with twelve public information fairs in the region.

The Netzverstärkung Ost project is part of the ÖNIP. The goal is to increase the east-west transmission capacities of the grid in order to make electricity generated from renewable energy sources in eastern Austria available throughout the country and to strengthen long-term supply security. The project involves the dismantling and construction of new overhead lines as well as the construction and expansion of substations, for example in Parndorf. In total, the construction of approximately 75 km is offset by the dismantling of approximately 70 km. In addition, a higher-capacity carbon cable will be installed on 16 km of the existing line.

Start of subsoil investigations

Austrian Power Grid (APG) starts on-site ground investigations in November as part of the Grid Reinforcement East project. The background to this is the planned construction and expansion of the 380 kV transmission grid in Lower Austria and Burgenland. The Grid Reinforcement East project comprises the conversion and new construction of a 380 kV overhead line in eastern Lower Austria and northern Burgenland, between Trumau (Lower Austria) and Zurndorf (Burgenland). A new high-performance connection is being planned over a length of just over 60 kilometers. The construction, expansion and conversion of local substations is also planned.In Burgenland, the project will be carried out in cooperation with Netz Burgenland and adjustments will be made to the 110 kV distribution grid. The new 380 kV line, most of which will run alongside or instead of existing lines, will increase the reliability of the region's electricity supply.

In order to be able to plan the project in detail, APG employees and experts commissioned by APG will be carrying out ground investigations on properties in the affected municipalities - in the districts of Baden, Mödling, Bruck an der Leitha and Neusiedl am See - over the coming months. The sole purpose of this work is to explore the conditions for an optimal route. The exploration campaign consisting of 22 core drillings and 40 excavator trenches with dynamic probing will start in November and is expected to last until the end of February 2026. The affected municipalities and property owners have already been personally informed about the work.

Information on the planned grid expansion in Lower Austria and Burgenland

The Grid Reinforcement East project comprises the conversion and new construction of a 380 kV overhead line in eastern Lower Austria and northern Burgenland, between Trumau (Lower Austria) and Zurndorf (Burgenland). A new high-performance connection is planned over a length of around 60 kilometers. In addition, the expansion and conversion of local substations is planned. In Burgenland, the project will be carried out in cooperation with Netz Burgenland and adjustments will be made to the 110 kV distribution grid.
