Challenging points for Kurzeme loop reconstruction
Low power supply reliability due to bottlenecks in the Kurzeme network; emergency disconnections (internal or neighboring country network related disturbances);
Baltic region power network strong dependency from limited power suppliers and isolation from European power market;
Limited generating capacity development in Latvia (usage of renewable power )

Stages of the project implementation “Riga loop” – 330 kV cable line s/st. “Imanta” – s/st. Riga TPP-1
(commissioning 2012); Existing 110 kV power line reconstruction, by strengthening it with
a 330 kV overhead line in section Grobiņa - Ventspils (2011-2013); Construction of 330/110 kV substation in Ventspils (next to the
existing substation site) (2011-2013); Existing 110 kV power line reconstruction, by strengthening it with
a 330 kV overhead line in section Ventspils – Dundaga – Tume, new 330 kV overhead line construction in section Tume – Riga (2018);
Currently an environmental impact assessment procedure for power line section Grobiņa - Ventspils - Dundaga and easement agreements signing with landowners are taking place.
