The Elering-managed electricity transmission network connects Estonian power plants, distribution networks and electricity consumers into a single whole.

The Estonian electricity system is part of the large synchronous operational united system BRELL, which comprises the AC power lines that connect Estonia with the neighbouring countries of Latvia and Russia and their neighbours Lithuania and Belarus. Estonia is connected to Russia via three 330kV lines – two of these run from Narva to St Petersburg and Kingisepp and the third from Tartu to Pskov. We are connected to the Latvian electricity system by two 330kV lines – Tartu-Valmiera and Tsirguliina-Valmiera.

Since the middle of the last decade, Estonia has become increasingly linked to the western European electricity system. In 2006, the EstLink 1 direct current interconnection between Estonia and Finland was completed, making it the first interconnection for Estonia and the Baltic states with Scandinavia. The second Estonia-Finland direct current interconnection, EstLink 2, was completed in 2014 and boosted the transmission capacity between the two countries to 1,000 megawatts. The Baltic states together with Finland, Sweden and Denmark make up a single electricity market.

In the long term, Elering’s strategic objective is the electricity system’s desynchronization from BRELL and switching to synchronised operations with the Nordic frequency area.

Elering as a system operator

Elering operates as the transmission system operator for the Estonian electricity network, with the task of planning the operation and managing the system in such a way that the network’s safe and reliable operation is always ensured. Besides enabling electrical energy transmission, Elering also has the task of balance handling to ensure a balance of consumption and production in the system at all times.

Estonia belongs to ENTSO-E, the European organisation for national transmission system operators. The organisation’s task, among others, is to improve transparency in the operation of the electricity market and system. The information system set up for this purpose is available at transparency.entsoe.eu.

The data archive includes all data regarding the Estonian electricity system since 2003. It is updated by the 7th day of each month. Data flows can also be followed on Elering Live.

Planned and actual data

The 2003-2009 files below include production/consumption data of the Estonian power system originating from SCADA; data about cross-border lines have been acquired from AMR (Automated Meter Reading).

The data files regarding the year 2010 and beyond also include the planned and actual data of the Estonian power system.

The planned data comes from the final balance plans of the power system, therefore the data also includes the intraday changes of balance providers. Actual data from Elering’s control and monitoring system SCADA is added for comparison. After every 5 minutes, the SCADA system saves the average measurement of the previous 5 minutes in its archive. In the files below for each hour the average of these 5-minute average measurements is calculated.
