How does electricity supply work in New Zealand?
Supplying electricity to homes and businesses across New Zealand involves three key elements: generating electricity, transporting electricity to distribution companies, and then selling it to customers.
How is electricity transported in New Zealand?
Electricity is transported at high voltage (up to 220,000 volts) through a high‑voltage alternating current system around New Zealand. To transfer electricity between the North and South Island, there is a high‑voltage direct current (HVDC) inter‑island cable with a transmission line under the Cook Strait.
How many new generation projects are delivering in New Zealand?
We're working hard to make these all these connections faster and reduce wait times. We are delivering 15 new generation projects right now which will collectively add 2,252 MW to New Zealand's electricity supply. The graphic above is an overview of our progress in connecting new generation and batteries to the national grid.
Why should New Zealand increase electricity production?
Increasing electricity production will also enable the decarbonisation of the economy – which is needed to meet New Zealand’s climate goals. Despite the building of more renewable generation plants, future prices 1 for winter , and remain high (see figure 1).
Will Bess become a cog in New Zealand's energy landscape?
We expect that BESS will also become an increasingly important cog in New Zealand’s broader energy landscape and that we will see utility-scale solar projects incorporating batteries as a means of providing dispatchable generation during peak demand and enhancing grid stability.
How do New Zealand generators make money?
The energy margins the New Zealand generators are making when selling into the wholesale electricity market. The transmission system or national grid transports electricity at high‑voltage from power stations, where it is generated, to large industrial users and local substations.
