Georgian electricity distribution company Telasi, a member of the Group Inter RAO UES, has constructed two-transformer 35/6 kV substation Chugureti which replaces the outdated TPP substation. The commissioning of a new power facility will substantially improve the quality and reliability of electricity supply for about 25 thousand customers in two central districts of Tbilisi: Chugureti and Mtatsminda.
Telasi launched the construction of the substation at the grounds of the former 'Teploelectrotsentral' (thermal power plant) in summer 2017. Under the project, a new substation building was constructed and electric equipment of modern standards installed. Two ABB power transformers with voltage of 35kV and capacity of 25 MW, 12 ABB distribution cells of 35 kV and 52 INVENT-electro distribution cells of 6 kV were installed at the substation. Relay protection, secondary and power supply circuits, switchgear and controlgear were also assembled.
In addition, Telasi began to lay a new double-circuit reserve cable line with overall length of 4.7 km which will connect Chugureti substation with Ortachala HPP. The reserve cable line will provide reliable energy supply for the substation and its customers.
Telasi's investments into substation construction and laying of a reserve cable line projects amounted to GEL 14 million.
The old TPP substation was commissioned in 1950. Due to its deterioration and unsafe condition, in 2016 the Georgian National Energy and Water Supply Regulatory Commission decided to construct a new two-transformer 35 kV substation. Pursuant to the Government of Georgia order No. 2618 of December 22, 2016, a sale agreement for a non-agricultural land plot of 1,200 square metres for construction of Chugureti substation was concluded between JSC Telasi and the National Agency of State Property. In accordance with the decision of a regulatory commission, the construction of the substation was to be completed before April 1, 2018.
'Despite the fact that relatively little time had been scheduled for the construction of the substation, the project was carried out within the stipulated time frame, thanks to the efforts of Telasi's employees,' Sergei Kobtsev, Director General of JSC Telasi said. 'Let me assure you that Telasi will continue its work on further development of the electricity grid of Tbilisi which will undoubtedly improve the quality and reliability of energy supply service for our customers.'
