Thorough reconstruction and rehabilitation was carried out to 18 GSE substations in 2010-2015. Within the scope of the USAID-funded projects, reconstruction and installation of 35/10/6 kV primary and secondary switchgears was carried out in 13 GSE substations: Fero 220, Rustavi 220, Zestafoni 500, Batumi 220, Gori 200, Khashuri 220, Marneuli 220, Menji 220, Tskaltubo 220, Zugdidi 220, Gardabani 500, Gurjaani 220, Kutaisi 220.

In addition, the protection and control equipment was procured and installed through USAID funding, in terms of both primary and secondary equipment, in the following GSE substations: Batumi 220/110, Gldani 220/110, Khashuri 220/110/10, Gori 220/110, Kutaisi 220/110/10, Marneuli 220/110, Menji 220/110/35, Rustavi 220/110, Tskaltubo 220/110 and Zugdidi 220/110.
