Meridian Energy Limited is a New Zealand electricity generator and retailer. The company generates the largest proportion of New Zealand's electricity, generating 35 percent of the country's electricity in the year ending December 2014, and is the fourth largest retailer, with 14 percent of market share in terms of customers as of December 2015. [3] [4]
Meridian was one of three electricity companies formed from the break-up of the Electricity Corporation of New Zealand (ECNZ) in 1998–99, taking over the Waitaki River and the Manapouri hydro schemes. Originally a state-owned enterprise wholly owned by the New Zealand Government, the company was partially privatised in October 2013 by the Fifth National Government, with the government retaining a 51.02% shareholding.
Today, Meridian operates seven hydroelectric power stations and one wind farm in the South Island of New Zealand, and four wind farms in the North Island.
Meridian originated from the break-up of the Electricity Corporation of New Zealand (ECNZ) in 1999 as a result of the reforms of the New Zealand Electricity Market. Meridian's share of ECNZ was corporatised as a state-owned enterprise with its own board of directors and with two Ministerial shareholders: the Minister of Finance and the Minister of State-Owned Enterprises. In 2013 it was partially privatised by the fifth National Government of New Zealand. [5]
As part of reforms, local electricity companies were split into lines and retail and the retail portion sold off. Meridian initially acquired the retail base of Northpower, Centralines, Scanpower, and Network Waitaki, and later acquired Orion's retail base from NGC.
Meridian Energy owns and operates seven hydroelectric power stations in the South Island – six on the Waitaki River and at Manapouri. It also owns and operates five wind farms in New Zealand, and a single turbine in Brooklyn, Wellington. In total, Meridian has a total installed capacity of 2,754 MW in New Zealand and 201 MW overseas.

In 2006, Greenpeace judged Meridian as the only "green" electricity company in New Zealand. [22] In 2007, Meridian announced that it had received CarboNZero certification from Landcare Research confirming that the generation and retailing of its electricity was carbon neutral. [23] [24]
In 2008, Meridian issued and sold the first carbon credits issued and sold under the JI program of the Kyoto Protocol.[ citation needed ]
In June 2008, National's Climate Change spokesman Nick Smith complained to the Commerce Commission that Meridian's claim of carbon neutrality in its advertising was misleading as Smith considered that Meridian had to buy thermally generated power during dry years to supply its customers. A spokesman for Meridian said they stood by the validity of the certification of their carbon-neutral status. [25] In July 2009, the Commerce Commission concluded that Meridian's statements of carbon neutrality were not misleading. [26]
In 2015 Meridian began converting its business fleet to electric vehicles in an effort to reduce carbon emissions. [27] In early 2019 Meridian joined the EV100 initiative, it has committed to its light passenger vehicle business fleet becoming 100% electric by 2030. [28] In August 2019 the company won the Deloitte Energy Award for a Low Carbon Initiative for its work on electric business fleet conversion. [29]
Meridian Energy are National Partners of the Department of Conservation Kākāpō Recovery Programme since 2016. Kākāpō are an endangered New Zealand native parrot.

In 1990 Meridian established Project River Recovery, [31] recognising the impacts of hydroelectric development from the 1930s to the 1980s on the Waitaki's braided rivers and wetlands. [32] Project River Recovery's work is run by the New Zealand Department of Conservation and includes intensive weed control, predator control, construction of wetlands, and research and monitoring programmes. When Tekapo A and Tekapo B were sold to Genesis Energy in 2011, the electricity company joined the compensatory funding agreement. [33]
In 1996 the Waiau Fisheries and Wildlife Enhancement Trust was formed to mitigate and improve the Waiau River from impacts by the Manapouri Hydro Station. The trust was established in partnership with the Waiau Working Party and ECNZ (now Meridian Energy Limited). [34] The area covered is from Te Wae Wae Bay in the south to Lake Te Anau in the north. The work focuses on enhancing wetlands, waterways and riparian plantings.
Wellington, New Zealand's capital city, is well known for wind and the Meridian Energy Wind Sculpture walkway celebrates this. In 2007 the four sculptures won Best Public Art [35] and the final piece was opened in May 2010. [36] The five sculptures are the 'Zephyrometer' by Phil Price, 'Urban Forest' by Leon van den Eijkel (in collaboration with Allan Brown), 'Akau Tangi' by Phil Dadson, 'Tower of Light' by Andrew Drummond and 'Pacific Grass' by Kon Dimopoulos. The sculptures are managed by the Wellington Sculpture Trust [37]
In 2013 Meridian became the principle partner of the KidsCan Charity. [38] In April 2019 the company committed to a further three years of support, helping provide lunches, raincoats, shoes and warm clothing to kids in need. [39]
Meridian supports communities near its generation assets through the Power Up fund. [40] This includes promoting conservation, community and educational efforts in seven communities around New Zealand.
In 2019, Meridian was found to mislead consumers when they implied the electricity they retailed was 100% renewable after a complaint was brought to the Advertising Standards Authority by rival retailer Electric Kiwi. [41] Additionally, Meridian Energy was found to have pushed up power prices in December 2019 by unnecessarily spilling water from its South Island dams that could have been used for generation, according to a preliminary ruling from New Zealand's Electricity Authority. [42]

Manapōuri Power Station is an underground hydroelectric power station on the western arm of Lake Manapouri in Fiordland National Park, in the South Island of New Zealand. At 854 MW installed capacity, it is the largest hydroelectric power station in New Zealand, and the second largest power station in New Zealand. The station is noted for the controversy and environmental protests by the Save Manapouri Campaign against raising the level of Lake Manapouri to increase the station's hydraulic head, which galvanised New Zealanders and was one of the foundations of the New Zealand environmental movement.
The Waitaki River is a large braided river on the South Island of New Zealand. It drains the Mackenzie Basin and runs 209 kilometres (130 mi) south-east to enter the Pacific Ocean between Timaru and Oamaru on the east coast. It starts at the confluence of the Ōhau and Tekapo rivers, now at the head of the artificial Lake Benmore, these rivers being fed by three large glacial lakes, Pukaki, Tekapo, and Ōhau at the base of the Southern Alps. The Waitaki flows through Lake Benmore, Lake Aviemore and Lake Waitaki, these lakes being contained by hydroelectric dams, Benmore Dam, Aviemore Dam and Waitaki Dam. The Waitaki has several tributaries, notably the Ahuriri River and the Hakataramea River. It passes Kurow and Glenavy before entering the Pacific Ocean. The River lends its name the Waitaki District on the south side of the river bank.
Lake Benmore is New Zealand's largest artificial lake. Located in the South Island of New Zealand and part of the Waitaki River, it was created in the 1960s by construction of Benmore Dam.

The electricity sector in New Zealand uses mainly renewable energy, such as hydropower, geothermal power and increasingly wind energy. As of 2021, the country generated 81.2% of its electricity from renewable sources. The strategy of electrification is being pursued to enhance the penetration of renewable energy sources and to reduce greenhouse gas (GHG) emissions across all sectors of the economy. In 2021, electricity consumption reached 40 Terawatt-hours (TWh), representing a 0.2% increase compared to the consumption levels in 2010.
Hydroelectric power in New Zealand has been a part of the country's energy system for over 100 years and continues to provide more than half of the country's electricity needs. Hydroelectricity is the primary source of renewable energy in New Zealand. Power is generated the most in the South Island and is used most in the North Island.
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.

The Waitaki Dam is one of eight hydroelectric power stations which form the Waitaki hydroelectric scheme on the Waitaki River in the Canterbury Region of New Zealand. The dam was the first of three to be built on the Waitaki River and was constructed without earthmoving machinery; over half a million cubic metres of material was excavated, almost entirely by pick-and-shovel. The Waitaki Dam's construction was followed by the development of Aviemore Dam and Benmore Dam, and importantly, every dam built in New Zealand since the Waitaki has benefited from lessons learned during its construction.
