Austria provides a comprehensive overview of hosting capacity through regularly updated publications by the Austrian TSO (APG) and the Austrian DSOs.  

At the TSO level, hosting capacity is calculated and published monthly on the APG website in accordance with legal requirements. The published information reflects the available capacity across the entire APG transmission grid and is detailed at the substation level. Additionally, APG publishes the cumulative power of open connection requests, broken down by federal region (Bundesland), and indicates whether a substation offers a flexible connection possibility. 

In both datasets, a distinction is made between generation and consumption. A hosting capacity of 0 MW indicates that for at least one hour of the year, no power can be injected or consumed without (possible) congestion-related constraints imposed by the TSO. The calculation is based on grid simulations aligned with the Ten-Year Network Development Plan (TYNDP) and uses market simulations based on indicative market prices for the year 2030 (status 2025). The published hosting capacity is independent of switching bay availability and dynamic aspects like short-circuit currents. 

At the DSO level, the capacity map is designed to provide grid users, project developers, etc., with an indicative (although not legally binding) overview of available and reserved grid hosting capacities on the busbar of the medium voltage (MV) level of each primary substation. The calculation is done by DSOs based on a uniform methodology defined in a regulation by the National Regulatory Authority (NRA).
