Common use of Labrador - Island Overland HVdc Transmission Clause in Contracts

Labrador - Island Overland HVdc Transmission.  An HVdc overhead transmission line, ±350 kV bi-pole, to connect the Muskrat Falls Converter Station to the Labrador Transition Compound at the Strait of Belle Isle and then to connect the Northern Peninsula Transition Compound at the Strait of Belle Isle to the Soldiers Pond Converter Station.  Transmission line to carry both poles (single conductor per pole) and one OPGW. The Labrador section is to carry two electrode conductors from the Muskrat Falls Converter Station to Xxxxxxx Xxxxx (xxx 0000 Xxxxxxxxx Xxxx - Xxxxxxxx).  The HVdc transmission line is to have a designed nominal power capacity of 900 MW; however, given the mono-polar operation criteria, each pole is to have a nominal rating of 450 MW with 100% overload capacity for ten minutes and 50% overload capacity for continuous operation.  Counterpoise installed from station-to-station.  Towers are to be galvanized lattice steel, with self-supported angles and dead ends, and guyed suspension towers.  50 year Reliability Level Return Period of loads, with respect to Nalcor Energy operating experience and LCP specific modeling and test programs.
