total length of 430 km and one 1,000 kV substation. One of the two lines, called the North-South
Line, is 190 km long and starts from the nuclear
power plants along the north-west coast to the
Tokyo region further south. The second line, the
East-West Line, is 240 km long and connects
power plants along the east coast of the Pacific
Ocean This line has been operating at reduced
voltage because of lower load requirements.
Italy started to build a 1,050 kV UHV
experimental line of 3 km in 1984 at the Suvereto experiment station. It was completed in
October 1995 and operated until December 1997
at a rated voltage of 1,050 kV, providing some
operational experience.
Second, practical deployment in projects.
Countries in Europe, Africa, Asia and the
Americas have constructed long-distance power
transmission projects and developed long-term
plans for them in recent years. These plans
include the European Ten-Year Network Development Plan, US Grid 2030, and EHV/UHV
power transmission projects in India, Brazil and
countries within China’s Belt and Road Initiative
for global development.
The European Network of Transmission System Operators for Electricity (ENTSO-E) published the draft of a new pan-European Ten-Year
Network Development Plan (TYNDP) in July
2014. TYNDP sets 2030 as the milestone for
Europe to achieve its energy targets and it
describes the coming investment programmes for
the European power transmission network. Its
guidance is mandatory and ensured by legislation. According to TYNDP 2014, Europe needs
to invest EUR 150 billion in the construction and
upgrading of about 48,000 km of high voltage
power transmission lines for the pan-European
grid. This investment is needed to transfer
renewable energy from around the North Sea to
other parts of Europe. The large-scale development of renewables will require the construction
of more long-distance and large-capacity transmission projects to interconnect countries in a
pan-European power grid. TYNDP 2014 expects
the average transmission capacity of the European grid to be doubled by 2030.
In Brazil, the Belo Monte UHVDC transmission project
56 connects vast hydropower resources along the Amazon River and branches in the
north with the Rio de Janeiro and Sao Paulo load
centres in the south-east, up to 2,500 km away.
Long-distance, large-capacity UHV power
transmission is the only way to harness these
hydropower resources and transport the energy to
where it is needed.
The joint venture between the State Grid
Corporation of China and the Brazilian utility
Electrobras won the order for the ±800 kV
UHVDC power link in 2014. The line, 2,092 km
long, starts from the Belo Monte hydropower
plant on the Xingu River and ends at the Estreito
converter station in Iberaci. It is the first
±800 kV UHVDC power transmission line in
the Americas. It was inaugurated in 2017.
In 2015, State Grid Corporation of China won
a 30-year concession to build and operate a
second ±800 kV UHVDC transmission link
from the Belo Monte hydropower station. Belo
Monte has an installed capacity of 11.2 GW, the
second largest in Brazil. The transmission project
includes one ±800 kV UHVDC power transmission line of 2,518 km, a converter station at
each end and auxiliary projects. The link has a
power transmission capacity of 4 GW and is
scheduled to start commercial operation in 2020
(Fig. 42).

: to transmit hydropower
from the north-east and thermal power from central
regions, India has built two ±800 kV UHVDC
links: Biswanath Chariali–Agra (1,728 km) and
Champa–Kurukshetra (1,365 km). The two links
transmit surplus power from eight states in the
north-east to the north, where there is a shortage of
electricity. This not only powers industrial development in the north, but delivers economic benefits
to the north-east, where the economy needs
development.
