HVDC Pole 3 Commissioning Update

19 April 2013

After considering the challenge of higher-powered testing in the present hydrology conditions, Transpower has confirmed that it will make Pole 3 available in the market upon completion of the medium power tests. Full power tests to 700 MW will be deferred to spring due to the continued unfavourable hydrology conditions.

Completion of the medium power tests will allow Pole 3 to be made available with a capacity not less than 350 MW, and possibly up to 450 MW. These tests will be challenging but feasible with the full cooperation of the market. The target date for completing them, assuming the required load flows can be attained, is 10 May. The bipole outage originally scheduled this month will not be required.
