New APG-Weinviertel Line

With the replacement of the more than 70-year-old Weinviertel line APG ensures now and in the future an efficient grid connection and thus the security of supply in the region and in all of Lower Austria. The new line is the precondition for further integrating wind and solar energy and distributing this energy in the region and all over Austria. With its completion in the summer of 2022 the power line will provide an essential contribution to a successful energy transition and the electrification of the economy, industry and society.

The Weinviertel line is currently one of the largest and most important APG projects for Austria. This line will facilitate the feed-in of the increasing production of wind power in the Weinviertel region in APG’s trans-regional transmission grid, which is thus made available and usable all over Austria. APG invests approximately 200 million euros in the business and residential area of Lower Austria.

The security of supply in the region and of Lower Austria as a whole is sustainably improved with the new line. Through the continuing integration of wind and solar energy from the Weinviertel region it will also play an important role for achieving the goals defined in the Lower Austrian Climate and Energy Strategy 2030 as well as the Austrian climate and energy targets.

The existing APG power line in the Waldviertel region was already more than 70 years old and due to its long operating time in need of renovation. In addition, it was no longer suited to handle the challenges of the future. Therefore it was necessary to develop a new routing for the line which takes into account the geographical development on the production side: the new APG Weinviertel line will run as 380 kV line from Seyring to the substation Zaya, which is being newly built within the scope of the project. At the substation Zaya a new connection to the Lower Austrian 110 kV grid and a 220 kV connection to the Czech border are being established. Mid-2022 both, the new Weinviertel line and the substation Zaya are scheduled to go on line.

Investment Volume
  • Approx. 200 million euros overall investment volume (Weinviertel line + substation Zaya)
  • In 2021 APG invests approx. 375 million euros in the Austrian grid infrastructure, until 2031 3.5 billion euros.
Facilitation of energy transition and electrification of society, economy and industry
  • With its completion mid-2022 the Weinviertel line will provide a considerable contribution to facilitating a secure and sustainable energy supply of the region and all of Austria.
  • It will facilitate the feed-in of wind and solar power from the Weinviertel region in the trans-regional grid of APG, thus making it available and usable all over Austria.
  • In the next decade many aspects of our life will depend on electricity. In particular, production processes in business and industry that to date have been powered with fossil fuels will converted and become electricity-based processes. The availability of enough electricity for Lower Austria is ensured by the new capacities of the Weinviertel line.
Boost for the national economy
  • In addition to improving the security of supply and facilitating the electrification of the economy, industry and society, the construction of the new Weinviertel line launches a whole value-added chain.
  • The 200 million investment will generate an added value of 132 million euros for Austria, with a share of 31 million euros for Lower Austria.
  • In total 2,100 jobs are created through the project, 600 of which in Lower Austria alone.
Line length
  • The new APG Weinviertel line will comprise 202 pylons and a total length of 63 km.
  • This is 53 pylons & 15 km line length less than the old.
Start of operation
Mid-2022 both, the new Weinviertel line and the substation Zaya are scheduled to go on line.
Line routing
The new APG Weinviertel line will run as 380 kV line from Seyring to the substation Zaya, which is being newly built within the scope of the project. At the substation Zaya a new connection to the Lower Austrian 110 kV grid and a 220 kV connection to the Czech border are being established.

With huge steps the construction works of the new Weinviertel line are approaching the finishing line.

“In project unit 1 and 3 all pylons have already been successfully assembled. In project unit 2 the final assembly works will be completed in the next few weeks”, confirms project manager Andreas Pischel. With the section method a pylon is assembled vertically by erecting the bottom section and then lifting and bolting the next section on the first aso. Overall the Weinviertel line will comprise 202 pylons, each of which with a height of approx. 60 meters.

Also the wire stringing works are well under way. This means that the transmission cables are being pulled into position along the route with a cable winch puller. Wherever possible and expedient the auxiliary rope – which is used to pull the actual cable wire through the winch – is being lifted up to the top of the pylon with a helicopter. This is faster and protects the ground along the transmission line route.

Once the Weinviertel line can go on line mid-2022, dismantlement of the pylons of the old Weinviertel line will start. In comparison with the existing line the new line will need 53 pylons and 15 km line less. With the construction of the new Weinviertel line APG invests approximately 200 million euros in the secure and sustainable energy future of Lower Austria and Austria as a whole. This investment will not only create necessary capacities in the power industry but also launch a value-added chain of 132 million euros for Austria, with a share of 31 million euros for Lower Austria.

Transformers are the heart of each substation. They convert the voltage of APG’s high-voltage grid to the voltages of the regional distribution system operators and vice versa.

Mid-May 2021 the first transformer arrived at its new place of work. Like its colleagues – which were delivered in June and September, respectively – the 300-ton colossus had to travel quite a long way: first, from the Siemens plant in Weiz by train to Hohenau an der March. There it had to be lifted with a special lift frame on a heavy-load vehicle which took it right to its foundations at the substation Zaya, a journey that took several days.

A transformer called "Carlo"

In July 2021 an old tradition was revived at the substation Neusiedl a. d. Zaya: the christening of the transformer. The president of the Lower Austrian provincial parliament, Karl Wilfing, took on the godparenthood. In the presence of APG’s CTO, Gerhard Christiner, the supervisory chairpersons of EVN, Stefan Szyszkowitz and Franz Mittermayer, Mayor Andreas Keller, the Captain of the fire brigade, OBI Roman Stur, and various media representatives he named the approximately 300-ton transformer “Carlo”, according to his own nickname.

“Like I am fired up to support the positive development of our country, the new transformer ‘Carlo’ will be fired up to contribute to a successful energy transition and a secure and sustainable energy supply. Therefore I am very pleased to take on the godparenthood for the 300-ton giant ‘Carlos’. It is part of the Lower Austrian Climate and Energy Strategy and shows how important it is to translate set goals into action”, states the president of the Lower Austrian provincial parliament, Karl Wilfing, happily.
