Available energy

Free capacity provides an overview of unused resources in regional substations. The interactive map shows which substations in the neighbourhood do not require costly construction work, such as changing the capacity of Elering's main network.

How to join

In the case of an energy-intensive electricity producer and a medium-voltage subscriber, the connection fee is formed according to the actual costs necessary to build a connection with the desired capacity. In the absence of sufficient capacity, it must be borne in mind that the network operator and the transmission system operator will have to agree on new conditions of consumption and/or production, which may take a long time and lead to costly upgrades to the transmission system.

To find the available capacities, check out the map application below. To find out the exact connection fee and connection deadline, submit a connection application.

Available capacities in substations

Clicking on the substation icon opens an information window with the substation name and free power value. At the top right of the map, the search can be narrowed down to indicate whether spare capacity is displayed in the direction of consumption or production. The capacities shown are for information only.

Elering's interactive map application

The transmission system operator Elering has also developed an interactive map application that shows available connection capacities at transmission system substations. As Elektrilevi's connection points within the transmission system are located at the same substations, Elektrilevi and Elering map applications both show the same substations.

Elering's interactive map application

Any differences between the resources shown on the Elering and Elektrilevi maps are due to the fact that Elering's map shows available capacities at 110 kV that apply to customers who are joining the transmission system and need a new network connection.

Eleketrilevi's map shows the available capacity on the low voltage side of the substation (at 6, 10, 15 or 20 kV depending on the substation) and takes into account the network contract with the transmission network, the capacity of the substation's equipment, and the network and connection contracts signed with existing customers.

If the customer connecting to the transmission network wants access to higher capacity than that displayed on the map, then the actual work volume and time cost required for connection will be determined in the process of preparing a connection offer.
