substations, underground stations, anonymous stations in load centers,
and introducing smart grids in power transmission.
Regarding interconnections with neighboring countries, the roadmap
specifies four goals. First, it calls for continuing to collaboratively study
power connection development with neighboring countries in ASEAN
and the Greater Mekong Subregion. Second, it advocates connecting to
Laos’ power grid through 220 kV transmission lines to import electricity
from hydropower plants in Southern and Central Laos. Third, it specifies
maintaining the connection with Cambodia through the existing 220 kV
transmission lines and conducting research on improving the existing
interconnection between Vietnam and Cambodia through multilateral
and bilateral programs. Fourth, it advocates maintaining the connection
with China through the existing 220 and 110 kV transmission lines,
conducting research on asynchronously harmonizing the power system
through single and alternative substations, and conducting research on
exchanging power with China through 500 kV transmission lines.
Electricity Import and Export
Vietnam currently imports electricity from Laos, especially from Xekaman
1 and 3 hydropower plants, which have a capacity of 540 MW. It is
expected that by 2020, Vietnam will import electricity from Xekaman
plants 1, 3, and 4, and the Xekaman Sanxay hydropower plant, which
comprises a total installed capacity of 635 MW, and annual electricity
generation of 2 billion kWh. By 2030, Vietnam expects to import electricity from hydropower plants with a capacity of approximately 2000 MW
at Xekong 1 and 2, plus from some small hydropower plants.
Vietnam also imports electricity from China at a maximum capacity of
700 MW. By 2020, the total electricity generation of 3.5 billion kWh will
be annually imported through the 220 kV transmission line in the North.
By 2025, Vietnam starts importing electricity from China through 500 kV
transmission lines, and by 2030, the power will be directly transmitted to
the South at a maximum capacity of 3000 MW. Vietnam exports electricity to Cambodia through 220 kV transmission lines with a maximum
capacity of 200 MW. Vietnam continues to export through 220 kV transmission lines. There is no plan to import electricity from Cambodia in the
near future.
