Map of Austria with one dot per substation and the power lines between them. Red dots, 0 MVA free, dominate the east and south. Green dots, 10 MVA or more, dominate Tyrol, Vorarlberg, Vienna and the Linz area. Grey dots have some room but less than 10 MVA.

Voltplot Grid is a map of the substations in Austria that still have feed-in capacity. Click your plot on the map to see the ones nearby, or search a substation by name.

You see a substation near you with 10 MVA or more free, its distance and its operator. Closer substations that are full show too.

FAQ

Where can I see free grid capacity at Austrian substations?

Austrian grid operators must publish the permissible, available and booked capacity of each substation on a shared online platform and update it every quarter; transformer stations must follow by December 2028 at the latest (§ 99 (1) ElWG). Voltplot Grid is a map of the substations in Austria that still have feed-in capacity. Click your site on the map and see which nearby substation still has 10 MVA or more free feed-in capacity.

Does free capacity on the list mean my plant gets connected?

No. § 99 ElWG gives no legal right to the published capacity. Vorarlberg Netz calls its figures non-binding and judges each request on its own. A request alone books nothing: for generation plants, only capacity reserved with a deposit or agreed by contract counts as booked (KBM-V §§ 3, 7). Requests can far exceed what is listed free: on 8 November, Netz Niederösterreich listed 494 MVA free, yet it received requests for 10,630 MW of large batteries between April 2024 and May 2026, almost seven times its peak load (grid development plan 2026, p. 31).

Is there any free capacity at all?

Transmission operator APG lists no unrestricted free capacity at any of its substations, but you can ask for flexible access (APG). Distribution operators must in principle connect you at a suitable point, even if they first have to reinforce or expand the grid, and must check flexible access when full feed-in access is not possible (§ 95 (2) and § 102 (2) ElWG).

What if the operator refuses access?

It must give transparent, traceable reasons and say which grid measures are needed and by when. On request, E-Control decides within a month whether the refusal was justified (§ 102 ElWG).

How are grid connection requests ranked?

Requests are ranked by the date all required permits are in hand. For a plant that needs no permit, the date of the request counts, if you own the land or prove the owner's consent (§ 99 (4) ElWG).

Does the publication duty cover battery storage?

Yes. § 99 ElWG requires operators to publish capacity for generation, consumption and storage plants. Generation capacity must be listed by technology. Voltplot Grid shows free feed-in capacity. Whether a storage plant can also draw power there, only the operator can say.
