CHMC constructs the first transmission substation in the Tbong Khmum province of Cambodia

by Jan 19, 2021

Electricite du Cambodge (EDC) inaugurated a new substation and a 230 kV HV transmission line on 14th January in Tbong Khmum province as part of the government’s efforts to promote power grid stability for the local population as well as the industries.

This is the first substation to be operational in Tbong Khmum province. Previously, the electricity supply in this province was brought from Kampong Cham, Prey Veng and was also imported from Vietnam. The substation will supply Tbong Khmum province as a whole and also distribute to Prey Veng province through the 230 kV transmission line, which will conduct first-phase operations at 115 kV. It will also connect to Svay Rieng province via existing 115 kV HV transmission lines. Moreover, the new substation was connected to all power plants in Preah Sihanouk province via the local grid.

To date, the government has commissioned 34 transmission substations across the country. Nationwide electricity consumption fell in 2020 by 10 to 12% due to interruptions of industries due to Covid-19. The greatest impact on consumption was seen in the garment sector where industrial production accounts for more than 40% of the total consumption. Prior to the pandemic, EDC had projected the electricity demand in Cambodia to reach a record high of 2.5 GW by 2021.

Supervision of this project was handled by EDC engineers with assistance from technical advisors sent by the French government from its French Development Agency. In addition, the primary construction of the 230 kV transmission line was realized by collaboration between Cambodia and China. Also, the substation was built by the China National Heavy Machinery Corporation (CHMC). Link to the news:
