4. 2014.10.12. "Kurzemes loks" 4 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 )

6. Benefits from project realization 2014.10.12. "Kurzemes loks" 6 Increased power supply reliability in Kurzeme region; Removed limitations for power demand development and new powerful consumers connection; Improvement of Baltic power supply reliability providing Latvia – Estonia and Lithuania – Sweden interconnection efficiency; Extension of power trade between Baltic Sea region countries.

7. 2014.10.12. "Kurzemes loks" 7 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.

8. Finance sources of the project 1 st stage Project “Kurzemes loks” is realized in framework of European Union financial support: Project environmental impact assessment and power line right-of-way study - 50% ("2009 Annual Work Programme for Grants in the field of trans – European energy networks") Project Stage Grobiņa - Ventspils construction - 50% (“European Programme for Energy Recovery”) 2014.10.12.8 "Kurzemes loks"
