About New Zealand nortmar power system
The National Grid is the nationwide system of electric power transmission in New Zealand. The grid is owned, operated and maintained by Transpower New Zealand, a state-owned enterprise, although some lines are owned by local distribution companies and leased to Transpower. In total, the national grid contains 11,803 kilometres (7,334 mi) of high-voltage lines and 178 su. The National Grid is the nationwide system of electric power transmission in New Zealand. The grid is owned, operated and maintained by Transpower New Zealand, a state-owned enterprise, although some lines are owned by local distribution companies and leased to Transpower. In total, the national grid contains 11,803 kilometres (7,334 mi) of high-voltage lines and 178 substations.Much of New Zealand’s electricity generation is hydroelectric, the majority of which is from power stations on lakes and rivers in the lower half of the South Island, while most of the electricity demand is in the North Island, in particular, the Auckland region. Consequently, large amounts of electricity need to be transmitted long distances from power stations to electricity users, including transmission across Cook Strait through the HVDC Inter-Island link. Investments in new transmission are regulated by the Electricity Commission and the Commerce Commission.In a news release in January 2012, the Commerce Commission reported that Transpower was planning to invest $5 billion over the next 10 years in upgrades of critical infrastructure.

There was a two-mile-long (3.2 km) from the generating station to the stamping battery.The first transmission line constructed by the government was associated with the near Rotorua.Electricity was transmitted at 3.3 kV over a 13-mile (21 km) route to Rotorua, and was used to drive sewage pumps, and some public buildings including five thermal baths.The first major transmission line in the North Island was constructed in 1913-14, connecting thetoto meet the power requirements of the stamp battery 5 miles (8.0 km) further on at the gold mine.The line length between Horahora and Waikino was 45 miles (72 km), and the transmission voltage was 50 kV, which was to set a precedent for North Island transmission voltage for many years.The first major transmission line in the South Island was constructed by the government as part of thedevelopment and was commissioned in 1914.Two transmission lines operating at 66 kV carried the power from Coleridge over a distance of 65 miles (105 km) to .
The backbone of New Zealand's national grid is the network of 220 kV transmission lines in each of the North and South Islands, which links the major power stations and the country's major cities. Supplementing this are 110 kV, 66 kV and 50 kV transmission lines, which supply provincial towns and cities with electricity from the 220 kV grid, and also connect smaller power st.

Auckland and NorthlandAuckland's power grid has suffered several famous , such as the 5-week long caused by failure of cables in the Mercury Energy distribution network. Because of the location of the major load centres in Auckland city, the geography of the , and the historical development of the grid, all but one of the transmission lines from the south converge on Otahuhu substation creating limited in the network.A major transmission failure occurred at Otahuhu substation on 12 June 2006, leading to the . It started at 8:30 am local time, with most areas of Auckland regaining power by 2:45 pm local time. It affected so.

From here, it crosses theviafor 40 km to Oteranga Bay, west of . At Oteranga Bay, the HVDC line converts back to overhead lines to cover the last 35 km, with the line terminating and connecting to the North Island's 220 kV grid atin . The main reason for a power system connection between the two islands is due to New Zealand's geography and demographics. The South Island has a large number of rivers suitable for hydroelectricity generation, however 75% of New Zealand's population lives in the North Island. HVDC was chosen for the inter-island connection because it is a more practical and economical solution for long distance transmission, particularly where significant lengths of cable are required.
