Market Services Help Desk

About Market Services
The Market Services group is responsible for the day to day management of the electricity market services of the System Operator function. This includes provision of the System Operator service provider function under the Electricity Industry Participation Code (the 'Code').

These functions provide for:

  • the procurement and management of contracts for ancillary services (black start, frequency keeping, voltage support and instantaneous reserves) to meet grid security objectives
  • the support of the competitive wholesale market, in which individual generators and energy retailers compete to buy and sell energy
  • the ongoing development of frameworks, tools and systems to link the wholesale market to the physical generation and transmission equipment and systems
  • the monitoring and compliance of the System Operators obligations under the 'Code'.

The Market Services Team within the System Operator can assist with any market-related queries.

Please call our helpdesk phone on +64 4 494 7470 or email marketservices@transpower.co.nz during normal business hours with any market queries.
