APG controlcenter indoor
The backbone of Austria's electricity supply.
Power generation is based on an essential principle: in every second, exactly the same amount of electricity must be generated as is being consumed. Unless the balance between electricity supply and demand is kept within precise parameters, the system will fail and no power can be supplied.

As Austria's independent transmission system operator (TSO), APG’s primary responsibility is to maintain the supply-demand balance at all times.

About Us

Grid system operation 

Highly qualified experts make sure that all APG systems function smoothly and maintain the control and safety systems which are becoming increasingly complex as digitalisation advances. When malfunctions do occur, the APG line team works to quickly resolve the issue so that any interruptions to the power supply are as brief as possible.


Electricity market

As the operator of the trans-regional electricity transport network, APG is also responsible for the exchange of electricity with neighbouring countries. APG’s electricity market experts make sure that all national and international market participants have equal access to the electricity market.

Power Grid Control, APG’s control centre, was commissioned in the southeast of Vienna in 2009. This is the nerve centre for the Austrian transmission grid, and the centre’s equipment is just as modern and high-tech as the building’s architecture is striking.

As a crucial actor in the Austrian energy market, we play a key role in making Austria’s secure and clean energy future a reality. Our power grid supplies the platform for the future expansion of renewable energy sources. Without a high-performance, flexible electricity grid, new developments such as electromobility would be unthinkable.

In awareness of our great responsibility for ensuring a secure supply of electricity in Austria, we subject ourselves to the highest compliance standards.
