Liezen-Leoben Line

The existing 220 kV Liezen-Leoben line between the substations Weissenbach and Hessenberg was put into operation in 1958. After almost 70 years of operation, a general overhaul of the line is planned to make it fit for the future and thus ensure a reliable power supply in the region for the next decades.

In planning

General Overhaul Liezen-Leoben Line

The modernized line will increase the efficiency in the APG grid and ensure a secure power supply in the region. It is a prerequisite for future projects such as grid support for the Styrian grid operator Energienetze Steiermark and also plays a major role with regard to developments in the energy industry. This includes the further integration of renewable energies or new connections for industrial operations and power plant projects.

As important part of the east-west connection in the central APG grid, the modernized line will be a significant contribution to achieving the energy transition. It will facilitate the distribution of electricity from renewable energies across Austria to make it available wherever it is needed. The general overhaul of the Liezen-Leoben line creates the basis for sustainable development and the progressive electrification of businesses, industry and society in the region - now and for generations to come.

Frequently asked questions - FAQ

When will the line be generally overhauled?

The scheduled construction phase will start in 2028 and end in 2030.

What measures does the general overhaul include?

The Liezen-Leoben line will be generally overhauled to ensure the security of electricity supply in the region also for future generations.

This includes:

  • Retention of the voltage level of 220 kilovolt
  • Modernization of all components (pylons, foundations, grounding, fittings and cabling)
  • Replacement of the existing single rope by a so-called 2-rope bundle: to increase the transmission capacity and at the same time reduce the corona noise
  • Installation of new pylons at the same locations with identical pylon basis
  • Increasing the height of the pylons by up to 15 meters: to optimize environmental impact and increase the clearance height e.g. for agricultural equipment
How much is APG investing in the general overhaul of the Liezen-Leoben line?

The investment volume is approximately 160 million euros.

The indicated sum is a planning figure. Due to the long implementation period until 2030 this figure can be subject to price changes on the world market exacerbated by events such as the Corona pandemic or the Ukraine war.

Which approval procedure applies to the general overhaul?

A procedure initiated by APG in January 2022 with the provincial government of Styria to determine whether an EIA is necessary resulted in the decision that the general overhaul of the Liezen-Leoben line does not require an EIA and is therefore to be approved according to the Austrian High Voltage Lines Act (Starkstromwegegesetz, StWG).

How can my property be claimed?

A plot of land can be claimed for the following purposes:

  • By a pylon position
  • By transmission line crossing land (in this case only the transmission cables and the associated easement pass over or within the vicinity of the property)
  • By pylon position in or transmission line crossing forestry land

How the claimed agricultural and forestry areas are to be compensated is to be determined in a framework agreement, which will be drawn up together with the Styrian Chamber of Agriculture and Forestry. It is to regulate the calculation of the compensation payments payable to the landowners for the easement grants that are to be concluded conjointly under private law. This agreement also regulates a variety of general conditions regarding the construction and operation of the transmission line.

The framework agreement applies equally to all plots of land used and zoned for agricultural activities and/or forestry. This ensures a uniform and fair approach. APG attaches great importance to the equal treatment of all landowners.

For land not zoned for agriculture or forestry separate expert opinions will determine the amount of compensation.

How long is the Liezen-Leoben line and how many pylons does it comprise?

Total line length: 71.3 km

Number of pylons: 244
