High North Island prices coinciding with HVDC test on 3 October 2013
We initiated an enquiry into the reasons for unusually high North Island prices on 3 October 2013.
|Stage: 1 (Enquiry)||Status: On-going||Date commenced: 4 October 2013|
The grid owner (Transpower) was undertaking a commissioning test of Pole 2 at the time of the high prices. The test restricted HVDC transfer to 350MW South to North. This test also necessitated Pole 2 being classified as a secondary risk by the System Operator (also Transpower) which in turn increased the reserve requirements in the North Island.
We're interested in actions that coincided with the start of the test which included changes to offer prices and quantities of reserves and energy.
