Aurora Energy

Aurora Energy owns the distribution network carrying electricity from the national grid to more than 82,300 homes and businesses in Dunedin and Central Otago. Delta is the asset manager, operator and maintenance provider of the Aurora Energy network.

Corporatised in 1990, Aurora Energy carries on the business activities commenced in 1904, when the Waipori Falls Hydroelectric Company Ltd began construction of the Waipori power scheme. This company was acquired by the Dunedin City in 1907 and the city then commenced electricity distribution and, subsequently, appliance retailing; operating as an arm of local government.

Aurora Energy’s distribution system annually delivers around 1,320GWh of electricity, from five Transpower Grid Exit Points and seven local power generation supply points, to more than 82,300 homes and businesses.
