Estonia –Latvia third power transmission network interconnectionis important future infrastructure Project for the whole Baltic Sea region, providing security of power supply in the region, effective operation of energy market in the Baltics as well as market competitiveness both within the Baltic States and between Baltic States and Nordic countries.
Project is a serious step towards elimination of bottlenecks and increase of transfer cross-border capacity between Estonia and Latvia as well as prerogative for effective cross-border power trade and creation of competitive energy market. After commissioning project will provide transfer capacity increase for 500/600 MW in both directions.
Under the framework of the project it is planned to construct 330 kV high voltage power transmission line with the total length in the territories of Latvia and Estonia of approx.200 km between substation Kilingi-Nōmme in Estonia and Riga CHP-2 in Latvia. New power transmission line will be built mainly along existing right-of-ways of power transmission lines.
Project is to be completed by year 2020 and it is included in the Latvian and European transmission system development plans. Project costs in the Latvian territory are expected to be c.a. 100 mil. EUR.
Estonia-Latvia 3rd interconnection costs will be partially covered by European Commission from Connecting Europe Facility financial instruments.
On April, 2013 right of way and environmental impact studies has been started in the Latvian territory with co-financing from European Union TEN-E grants.
Latvian transmission system operator “Augstsprieguma tikls” AS is responsible for Estonia-Latvia 3rd electricity interconnection project realization in the Latvian territory.
