History

The history of electricity supply to Dunedin dates from 1907, when the Dunedin City Council developed New Zealand's first large hydro-electric generating station on the Waipori River. Power from the initial Waipori scheme was transmitted at 35 kV over a 45-kilometre (28 mi) route to Dunedin using duplicate lines. The Council continued with further hydro-electricity developments on the Waipori River for almost 80 years. The largest development on the river was the construction of a 34-metre (112 ft) high dam, forming Lake Mahinerangi. The Waipori scheme was interconnected with the Waitaki power station in 1935 as part of extending generating capacity in the South Island. [5]

As part of electricity industry reforms in 1990, the Dunedin City Council separated its lines and energy businesses. A new company Waipori Power Generation Limited, was formed to take over the energy business. In the same year, the Council established a utility contracting company that was eventually renamed as Delta Utility Services.[6] A further new company, Dunedin Electricity Limited was registered on 26 June 1990 to manage the Council's electricity lines business. Dunedin Electricity was subsequently re-registered and renamed as Aurora Energy on 1 July 2003.[7][8]

Distribution network

Aurora Energy's distribution network is supplied from Transpower's national grid at five grid exit points (GXPs): Halfway Bush and South Dunedin for the Dunedin network, and Clyde, Cromwell and Frankton for the Central Otago network. Most of the network's sub-transmission is at 33,000 volts with the major exception of the lines feeding Wanaka from Cromwell GXP, which operate at 66,000 volts. Distribution is at 6600 volts in the Dunedin urban area and the Clyde area, and at 11,000 volts elsewhere.

Regulation

As a natural monopoly lines business, Aurora Energy is subject to regulation under the Commerce Act 1986, including price-quality regulation, and Information Disclosure regulation.[10] The Commerce Commission publishes a wide range of Information Disclosure data provided by Aurora Energy.[11]

Criticisms and responses

In the period 2013 to 2020, there were multiple criticisms of Aurora Energy for poor network reliability, creating safety hazards for workers and the public, historic under-investment, and the need for large price increases to fund the renewal of ageing assets.

In 2013, the Commerce Commission published a report from Strata Energy Consulting that reviewed the Aurora network performance over the period 1 April 2010 to 31 March 2012. The review was commissioned because Aurora had not met the regulatory network reliability standards during that period. Strata concluded that although severe adverse weather had caused the poor performance, there were underlying factors that contributed, including increasing incidents of tree contact, and the poor condition of poles. Strata attributed these factors to insufficient investment in the network.[12]

In June 2014, the Commerce Commission warned several electricity distribution businesses, including Aurora, after they failed to comply with the service quality standards for electricity distributors in 2012. The Commission warned that these businesses were more likely to face penalties should they fail to comply with the standards in the future.[13]

In October 2016, Richard Healey, a former employee of Delta Utility Services, began raising concerns in the media about the state of the Aurora network assets, and the safety hazards they presented to workers and members of the public. At the time Delta Utility Services both managed the Aurora Energy network and was the primary contractor.[14][15][16] Following this criticism, a review of Delta Utility Services and Aurora was commissioned by Dunedin City Holdings Ltd and undertaken by Deloitte.[17] The report led to a restructuring of both Aurora and Delta, with the establishment of separate boards and chief executives.[18]

On 31 October 2016, Aurora announced a plan for fast-track replacement of several thousand power poles.[19] In May 2017, Aurora announced that it was planning a $720 million upgrade of the network over the next decade. This was a $300 million increase over the 10-year plan released the previous year. The revised 10-year plan included increased expenditure on asset renewal, extending to a total of 14,000 poles, the replacement of ageing sub-transmission cables and upgrading of overhead lines. Other major projects included a new substation at Carisbrook, to replace the 60-year-old Neville St substation by 2019, and a new Wanaka substation on Riverbank Rd, Wanaka.[20]

In June 2017, benchmarking data published by the Commerce Commission showed that on many of the measures used, Aurora was rated among the worst on both average age of its assets and their overall condition.[21] In October 2017, Aurora announced that it had appointed Dr Richard Fletcher as its new Chief Executive Officer, to replace the outgoing chief executive Grady Cameron. Dr Fletcher would take up the role in January 2018 after previously being a general manager at Powerco.[22]

In September 2018, the Commerce Commission announced that it had decided to file court proceedings against Aurora for breaching its regulated quality standards in 2016 and 2017.[23]

In 2018, the Commerce Commission published the results of an 8-months=long independent review of the Aurora network carried by WSP. In their summary of findings, WSP concluded that most assets pose a small risk to public safety, reliability or the environment, and that risks were no greater than they had observed in other networks in New Zealand and internationally. However, they reported that overhead conductors, poles and crossarm assets were causing more than 50% of the network outages that were attributed to asset deterioration, and that there was an upward trend in these failures.[24][25][26]

In May 2019, the Commerce Commission released a draft decision on the revenue regulation of electricity distribution businesses, and noted specifically that Aurora Energy required significant investment in its network.[27]

In March 2020, the Commerce Commission announced that Aurora Energy had been penalised with a fine in the High Court of almost $5 million for failing to meet regulated network reliability performance standards in the 2016–2019 years. In commenting on the High Court judgement, the Commission deputy chair Sue Begg, acknowledged that Aurora had taken a number of steps to improve service quality across its network since 2016, including appointing a new board and management and commencing a major capital works programme.[28]

Investment and revenue proposal 2021–24

In November 2019, Aurora commenced a consultation with the community about proposed investment for the period 2021 to 2024 and the likely impacts on lines charges. This consultation was part of preparations for an application to the Commerce Commission for a customised price-path.

The consultation documents indicated a three-year, $400 million programme to tackle ageing electricity infrastructure in Dunedin, Central Otago and Queenstown along with indicative price rises for its customers of up to $500 per annum. In one reaction to this announcement, the mayor of Queenstown-Lakes, Jim Boult, criticised the Dunedin City Council, as owner of Aurora, for taking high dividends that should have been spent on maintenance of the network.[29] The Member of Parliament for Dunedin South, Clare Curran, criticised Aurora for years of under-investment.[30]

In a response to an indicative increase of 23% in Aurora's line charges for Central Otago, members of the Queenstown-Lakes District Council and the Vincent Community Board claimed that the price increases were a direct result of on-going under-investment and the skimming of excessive dividends by Dunedin City Council. Russell Garbutt claimed that Dunedin City Council had required Aurora to borrow millions of dollars so it could pay dividends to help fund the building of Forsyth Barr Stadium. He called for the Dunedin City Council to repay excessive dividends that it had drawn from Aurora over many years. His claim was supported by University of Otago Associate Professor Mike Sam. who criticised the Dunedin City Council for funding the stadium from dividends from Aurora (thereby passing on the costs of the stadium to future electricity consumers), when the council had told the public that the stadium wasn't going to cost them anything.[31]

Aurora submitted its 3-year investment and revenue proposal to the Commerce Commission in June 2020. The proposal included investment of $383 million over the three-year period from 1 April 2021. In comments on the proposal, the Associate Commissioner John Crawford said that investment was undoubtedly needed in the Aurora network, and that the Commission's job was to decide the maximum revenue that Aurora should be allowed to recover from its consumers to carry out its plan and over what period.[32][33]
