Estonia to complete third Estonia–Latvia link’s substation in September [free access]

July 29, 2019

Reportedly, construction works for Elerings’—the Estonian transmission system operator—Kilingi-Nõmme substation is moving at a good pace, and it will be connected to the national grid by September 2019. The EUR3.1 million substation, being constructed by the local AS Merko Infra, is associated with the third electric power interconnection between Estonia and Latvia.


The interconnection aims to increase the security of supply and develop the electricity market in the Baltic region. The project is part of the European Union’s (EU) projects of common interest (PCI) list, and will provide a reliable transmission network corridor to improve interoperability among the Baltic States. It is also an important component of the Baltic Energy Market Interconnection Plan (BEMIP), which aims to connect Baltic countries to European electricity markets.


The Latvian TSO Augstsprieguma Tikls (AST) will undertake the construction of a 176-km-long, 330 kV line connecting the Riga second combined heat power plant in Latvia and the Estonian border. On the Estonian side, TSO Elering will construct another 28-km-long part of this line that falls in its territory, to the Kilingi-Nõmme substation. The EU’s Connecting Europe Facility (CEF) will cover 65 per cent of the contract's total cost, which is estimated at EUR74.6 million.


The design and construction of the link are performed by EE-LV Interconnection, a joint venture (JV) between Latvia-registered Elko, Poland's Selpol, and Estonia's Leonhard Weiss Energy.


The project is likely to be implemented by 2020.
