Litgrid launches tender for Gižai substation contractor

Litgrid, the Lithuanian electricity transmission system operator, has launched a tender to select a contractor for the construction of the Gižai substation. This facility is set to become a crucial element of the Harmony Link project, an ambitious initiative designed to bolster the electricity interconnection between Lithuania and Poland.

The selected contractor will be responsible for developing the detailed technical project and executing all construction work for the substation. Once completed, the Gižai substation will be the largest facility managed by Litgrid within Lithuania. It will serve as the primary connection point for the Harmony Link project to the Lithuanian national power grid.

A significant technical aspect of the Gižai substation will be its operation at a 220 kV voltage, a first for Litgrid. This voltage will then be transformed to 330 kV and 110 kV to integrate seamlessly with existing grid infrastructure. Both Lithuanian and international contractors with prior experience in electrical projects are eligible to participate in the tender.

Litgrid plans to sign the contract in the third quarter of 2027. Following the contract award, the construction work is expected to span 54 months, with the entire project slated for completion by the end of 2030. This development marks a significant step towards enhancing regional energy security and market integration.
