APG guarantees a secure power supply in Austria.

The power grid operated by Austrian Power Grid is the backbone of Austria's electricity supply. Power generation is based on a basic physical 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 the Austrian transmission system operator, APG’s primary responsibility is to maintain the supply-demand balance at all times.
