ABB has received an order from the
electric co-operative Great River Energy.
The contract, worth around $130 million,
is to upgrade an existing high voltage
direct current connection in the USA.
The 700km ±400kV HVDC transmission
system will provide a significant link
for transferring 1,000MW between
Underwood, North Dakota, and Buffalo,
Minnesota.
Within the project scope, ABB will
upgrade the converter valves, valve
cooling systems, control and protection
systems, and other related equipment at
the converter stations. The modernization
is intended to improve grid reliability and
efficiency.
