Transmission

The transmission system (often called the national grid) exists to link electricity generation stations to locations where there is demand for electricity. The national grid is owned, operated, maintained and developed by Transpower, a state-owned enterprise.

In this section you will find:

• a brief overview of the transmission system
• transmission Code and Regulations
• transmission work programmes, projects and consultations
• transmission agreements, including the benchmark agreement and connection codes
• the interconnection rules
• grid reliability standards
• transmission pricing and the transmission pricing methodology

Transmission processes and responsibilities are set out in Part 12 of the Electricity Industry Participation Code 2010 (Code).

As the grid owner, Transpower has a number of roles in the part 12 processes related to transmission. Transpower is responsible for working with the Authority to ensure the grid meets the required reliability and service levels, and that there is sufficient grid investment to meet New Zealand's needs. Transpower is responsible for grid planning, including proposing transmission investments to the Commerce Commission, and reporting on asset management plans and forecast grid capabilities over time. It has contracts with those parties that connect to the grid, setting out the terms on which parties connect to the grid and use the grid services provided.

The Authority's Director of Modelling and Forecasting is Bruce Smith.
