Genesis Energy Limited
Genesis Energy Limited, formerly Genesis Power Limited, is a New Zealand publicly listed electricity generation and electricity, natural gas and LPG retailing company. It was formed as part of the 1998-99 reform of the New Zealand electricity sector, taking its generation capacity from the breakup of the Electricity Corporation of New Zealand and taking retail customers from three local power boards in the Lower North Island.
Genesis Energy is the largest electricity and natural gas retailer in New Zealand, with 26% and 39% market share respectively in the 2015-2016 financial year. In 2015, Genesis produced 14% of New Zealand's electricity, and is the third largest electricity generating company in New Zealand in terms of MW capacity, GWh generation and revenue.
History
Genesis Energy began business on 1 April 1999, after the reform of the New Zealand electricity market and the breakup of the Electricity Corporation of New Zealand. It took over the Huntly Power Station, Tongariro Power Scheme and Waikaremoana Hydro Scheme from ECNZ, and the Hau Nui Wind Farm and the Kourarau Hydro Scheme from Wairarapa Electricity. It also inherited the retail arms of Powerco, Central Power and Wairarapa Electricity, while Powerco and Central Power concentrated on electricity distribution.During 2000 to 2002 Genesis Energy purchased several electricity and gas retailing entities, following changes to laws governing the electricity industry. These included electricity retail businesses of Todd Energy, and electricity and gas customers from NGC and Energy Online.
In September 2013, the company announced a change of name from Genesis Power Limited to Genesis Energy Limited.
On 17 April 2014, the National Government sold a 49% stake in Genesis Energy through an Initial Public Offering at NZ$1.55 per share.
In February 2018, Genesis Energy announced a pathway to a coal-free electricity future for New Zealand by 2030.
Power stations
Genesis Energy owns and operates a diverse portfolio of assets that includes hydroelectric, thermal and wind generation.Genesis Energy operates three hydroelectric generating stations on the Tongariro Power Scheme - Rangipo Tokaanu and Mangaio. The company also operates the Lake Waikaremoana hydro scheme including the Tuai, Kaitawa and Piripaua stations.
On 1 June 2011, Genesis Energy purchased Tekapo A and B hydroelectric power stations from Meridian Energy.
Genesis Energy operates the Huntly Power Station, a coal- and gas-fired thermal plant on the Waikato River. In addition to two gas/coal-fired generating units, Huntly has a 50 MW open-cycle gas turbine unit which runs as base load, and a combined cycle gas turbine commissioned in June 2007 as a NZ$500 million project. In addition to these units Huntly also has a third coal unit which can be taken out of storage within 90 days. The coal units are mainly used as hydro firming when NZ is in a dry winter.
The first of the four coal-fired units at the Huntly Power Station was taken out of service in late 2012. A second unit was placed into long-term storage in December 2013 and permanently retired in June 2015.
The company also operates the Hau Nui windfarm in the North Island.

School-gen
Genesis Energy began its School-gen programme in 2006 to teach students about solar power, renewable energy and energy efficiency. The School-gen program has created extensive teaching resources, including Maker Projects and eBooks that are free for any school in New Zealand. It has also provided 92 New Zealand schools with either a 2, 4 or 6 kilowatt photovoltaic solar panel system, at no cost to the schools. The largest solar array on a School-gen school is 16 kilowatts on Vauxhall School in Auckland. The PV system allows these schools to generate a portion of their electricity from the sun while also teaching students about solar energy.Whio Forever Project
Genesis Energy has partnered with the New Zealand Department of Conservation to help save the endangered native whio or blue duck. The Whio Forever Project includes a national recovery plan that will double the number of fully operational secure breeding sites throughout New Zealand and boost pest control efforts.Graeme Dingle Foundation
Genesis Energy has teamed up with the Graeme Dingle Foundation to support the roll out of their Kiwi Can programme in three Huntly primary schools. The foundation's Kiwi Can programme teaches primary school children life skills, values, and self-confidence so they can grow up with a positive outlook.Curtain Bank
Genesis Energy is the major sponsor of the Wellington Curtain Bank and the Christchurch Curtain Bank. The curtain banks take donated second-hand curtains or fabric and re-cut and line them for distribution to households in need. This helps households in saving money on their energy bills and to create warmer, healthier homes. Some retailers offer a service in which they take down and donate your old curtains when installing new ones.Other developments
