Electricity security

Long-term security and reliability of electricity supply requires regulatory certainty and effective and balanced rules.

Having a reliable electricity system means having enough generation to meet demand and having a diverse range of energy sources and locations.

A reliable electricity system also relies on an effective transmission and distribution system.

Who contributes to electricity security

The Electricity Authority has a statutory obligation, under the Electricity Industry Act 2010, to promote a reliable supply by the electricity industry for the long-term benefit of consumers (Electricity Industry Act s 15).

Details of the Electricity Authority’s role can be found on its website(external link).

A number of other agencies and organisations also contribute to the safe and secure supply of electricity in New Zealand. A selection of these agencies, and their respective roles, can be found through the following websites:

2009 review of the electricity market

The Government’s major electricity market review in 2009 resulted in a broad suite of proposals to increase security of supply.

New measures to promote secure electricity supply include phasing out the reserve energy scheme and ensuring that market participants have clear incentives to manage risk.
