LITGRID AB Member

Litgrid, the Lithuanian electricity transmission system operator (the TSO), secures stable operation of the national electricity system, controls electricity flows, and creates conditions for competition in the open electricity market. 

Main activities of Litgrid: responsible for maintaining the balance between electricity consumed and produced in the system and reliable transmission of electricity, and implementing strategic national electricity projects. Its vision and strategic operating guidelines are based on the long-term goals identified in the National Energy Independence Strategy (the NEIS). 

The most important activity areas and responsibilities of the Lithuanian TSO include:

• Maintenance of the country’s electricity infrastructure and its integration with the Western and Northern European electricity infrastructure.
• Development of the electricity market and participation in the creation of a single electricity market for the Baltic and European countries.
• Integration of the electricity systems of Lithuania and continental Europe for synchronous operations.

In implementing the programme on the synchronisation with the European continental networks, the Company carries out 20 projects of strategic importance approved by the Government of the Republic of Lithuania.

By systematically carrying out its daily functions, ensuring uninterrupted and smooth operation of the electricity transmission system, and implementing projects of national importance, the Company aims to create value for its customers. 

Electricity transmission is an intermediate link between electricity generation and distribution to consumers. The voltage of transmission networks is high or very high (110-440 kV). Electricity transmission networks consist of electricity transmission lines with substations. Power lines are connected in power substations with higher and lower voltage switchgear and transformers connecting them. In substation transformers, the voltage is reduced to the voltage of the distribution networks.

Litgrid not only transmits electricity via high-voltage lines but also takes care of the reliability of the entire transmission network: it is essential for us that electricity is always supplied to electricity consumers and that any faults are rectified as soon as possible. Reliability of electricity supply is the key to economic growth.
