Configuration of 220 kV Sataplia 1-2 OHL as Double-Circuit Transmission Line

The Rehabilitation Project – Configuration of 220 kV Sataplia OHL as Double-Circuit Transmission Line was implemented within the scope of Ten Year Network Development Plan approved by Order No 39 of 8 April 2015 of the Minister of Energy of Georgia as agreed with the Government of Georgia at the meeting held on 26 March 2015.

To this end, a decision was made to ensure the connection between Tskaltubo 220 substation and Kutaisi 220 substation by a new double-circuit section of 220 kV Sataplia OHL and a double-circuit section from No 53 support of 220 kV Derchi-Sataplia OHL to Tskaltubo substation (called Sataplia 1-2 OHL), ensuring the construction of a new right-of-way for 220 kV Derchi OHL instead of the above sections.

The 220 kV Sataplia Single-Circuit OHL Rehabilitation Project from No 53 support of double-circuit Derchi-Sataplia OHL to Kutaisi 220 substation was implemented on the basis of project works performed by the OHL Projects Department of JSC Georgian State Electrosystem.
