Network services

Under the Electricity Market Act there may be only one company in Estonia that provides an electricity transmission service as a Transmission System Operator or TSO. The Estonian Competition Authority has issued the licence for this to Elering.

In its service area, Elering provides the following network services to consumers, producers, power line operators or other network companies:

  • on application, connection of properly configured equipment to the network in its service area;
  • on application, modification of consumption or production conditions;
  • use of the network connection from a connection point;
  • transmission of electricity through the Elering network to or from connection points;
  • installation of legally approved measurement equipment in the network;
  • collection and processing of measurement data.

A network connection is an electrical connection between a network and other electrical equipment.

Use of a network connection means using network services through the network connection.

Transmission means passing electricity through the main grid network.

Elering signs a contract with its clients for the sale of transmission services, which covers:

  • an electrical design plan, which shows the connection points and the ownership limits of electrical equipment;
  • terms of use, which set a maximum permitted consumption capacity, the maximum permitted duration of planned outages, and the expected repair times for other outages;
  • a list of measuring devices for the electricity transmitted;
  • relay protection and automation equipment and the secondary equipment that is most important for system reliability, and the conditions related to these;
  • an agreement on the switching operations of electrical installations, stating which party gives the order for switching, which administrates it, and which carries it out;
  • the standard terms and conditions.


From May 1, 2024, Elering implemented the updated price packages for the transmission service, which the Competition Authority approved with decision No. 7-3/2024-003 on 26.01.2024.

The standard conditions for the provision of network services are an integral part of the network contract and apply both to network contracts concluded from 01.01.2024 and to network contracts already in force, regardless of whether the standard conditions are attached to the network contract or not.

The Competition Authority approved the new standard conditions on November 14, 2023.

Under the Electricity Market Act, the Competition Authority oversees whether market participants are complying with the Electricity Market Act and related laws.

Regulation No. 42 of the Minister of Economic Affairs and Communications of 06.04.2005 confirmed the quality requirements for network services, which was amended by Regulation No 51 of 09.06.2006.

The requirements for security of the electricity supply set the time limits for repairs if there is an outage caused by a fault. In this case Elering should restore power after the outage within two hours if the power supply to the point of consumption is carried by two or more 110 kV transformers or lines, and within 120 hours if the power supply to the point of consumption is carried by only one 110 kV transformer or line.

Quality requirements for network services are set by Regulation No. 104 of the Minister of Economic Affairs and Communications:

  • The network operator is obliged to register and to keep a separate record of all the service operations listed in § 3 section 3 of the Quality Requirements for Network Services and of the time taken to carry out each operation.
  • The network operator must register and keep a separate record of all the outages noted regionally and for individual points of consumption and of their length, making a distinction between planned outages, failures, and disruptions caused by force majeure.
  • The network operator must register and keep a separate record of all complaints from consumers about the quality of the electricity supply, including complaints about the voltage quality. At the end of each financial year the network operator submits data to the Competition Authority on the number of points of consumption where the voltage quality did not meet the standards stated in the Quality Requirements for Network Services §6.
  • The network operator submits a separate explanation for each outage that is caused by force majeure.

The most important criterias of the quality of the network service are the number of outages and energy not served.
