Through U.S. Agency for International Development's (USAID) Georgia Power and Gas Infrastructure Oversight Project (PGIOP), Tetra Tech is providing in-country professional engineering oversight and other technical services supporting power and gas transmission improvements in Georgia.

Tetra Tech’s PGIOP responsibilities complement and reinforce the activities, project management, and engineering expertise of USAID/Caucasus. The project continues our prior work on PGIOP, which concluded in 2012. Under the original project, Tetra Tech provided technical and advisory services related to grid upgrades, pipeline engineering, design, and construction management, preventative maintenance, as well as oversight of reliability improvements and enhanced emergency control system.

Tetra Tech is implementing PGIOP in collaboration with the Georgian Oil and Gas Company and the Georgia State Electrosystem to upgrade, replace, and install critical power and gas transmission infrastructure. These state-owned entities are charged with the import and transmission of electricity and natural gas throughout the country.

PGIOP is helping to build a viable and multi-functional energy sector in Georgia. Tetra Tech’s work is supporting USAID's objective of promoting energy security through greater access to electricity and natural gas supplies to households in Western Georgia. PGIOP is working towards securing power exports through in-country reliability-related infrastructure improvements and towards fostering sustainable development. 

PGIOP includes the following infrastructure projects:

  • Constructing a new 76 kilometer (km), 700 mm gas pipeline from Kutaisi to Senaki
  • Replacing 58 km of 220 kiloVolt (kV) transmission lines (Senaki I and II) dismantled in 1992 during Georgia’s civil war
  • Restoring power substations in Tskaltubo and Menji to support the Senaki I and II transmission lines
  • Constructing 43 km of a new 700 mm gas pipelines from Gori to Kareli and from Zestaphoni to Kutaisi

When the final phases of construction are complete, the Georgian Ministry of Energy will have the ability to provide enhanced power to customers throughout the country as well as natural gas to cities and towns from Gori to Poti.
