Project type |
HVDC
interconnector |
|
Location |
Between Benmore
(on the Waitaki River near Otematata) and Haywards (near
Wellington) |
|
Capacity |
-350 kV, 700 MW
(present), upgrading to 1,000 MW in 2012 |
|
Year of
commissioning |
1965 - mercury
arc bipole (capacity +/- 250 kV, 600 MW)
1991 - mercury arc, thyristor valve hybrid link (capacity
increase to +270/-350 kV, 1,240 MW)
2012 - planned - decommissioning of mercury arc valves and
upgrading with a thyristor pole. +/- 350 kV, 1,000 MW |
|
Purpose |
To connect
significant South Island hydroelectric generation with major
North Island load centres. Half of the mercury arc valves in
Pole1 were decommissioned in 2008, and the remaining half of
Pole1 continues to be in service under limited operating
conditions in the northwards direction only
In 1991, the
link was upgraded by adding a thyristor converter, and
reconfigured to increase capacity. The hybrid configuration
comprises two
poles:
- Pole 1 rated 270 kV, 540 MW using mercury arc valve
groups, and
- Pole 2 rated 350 kV, 700 MW with thyristor valves
A new pole will
replace Pole 1, increasing the north flow capacity of the
HVDC bipolar link to 1,000 MW from 2012 (Stage 1) and to
1,200 MW from 2014 (Stage 2) by the addition of a Statcom at
Haywards. A third stage (involving the addition of a new
submarine cable) to increase the capacity to 1,400 MW will
be implemented at a later date subject to regulatory
approval |
