Dennis Barnes to join Mercury Board

20 July 2021 - Senior Australasian energy sector leader, Dennis Barnes, has been appointed to the Mercury Board effective 1 September 2021. Mr Barnes joins the Board as a replacement for Keith Smith, who retires at the 2021 Annual Shareholders' Meeting in September after more than 12 years' service. Mr Barnes was most recently Chief Executive of Contact Energy, a nine year role during which he led that company's investment in renewable energy and flexible generation (including construction of the Te Mihi geothermal power station, the development of the Tauhara field and the introduction in 2011 of the Ahuroa gas storage facility and Stratford peaking plant). Before this role, Mr Barnes managed Origin Energy's significant portfolio of wholesale markets activities. Mr Barnes holds an MBA from Sheffield University Management School and a BSc (Hons) in Metallurgy and Microstructural Engineering from Sheffield Hallam University. Mercury Chair, Prue Flacks, said she was delighted to be welcoming Mr Barnes to the Mercury Board. "We have been working carefully towards an appointment that would ensure the Board added operational experience at the highest level in the New Zealand energy industry" Ms Flacks said. "Mercury is entering a development phase, with the construction of our first wind farm and the potential for further development of assets currently held by Mercury and assets to be acquired from Tilt Renewables. Mercury is well placed to make a significant contribution to the decarbonisation of New Zealand, but it is critical that we have a Board with the necessary skills, knowledge and expertise to ensure we deliver this strategic objective for the benefit of New Zealand and all our stakeholders," said Ms Flacks. Mercury's Chief Executive, Vince Hawksworth, welcomed the appointment. "Dennis has a deep understanding of New Zealand's energy markets, large scale asset investment and delivery experience, as well as much to contribute to Mercury in a broader sense including Health and Safety and people leadership". "I know Dennis is looking forward to making an ongoing contribution to the decarbonisation of New Zealand and continuing his personal connection to Aotearoa," Mr Hawksworth said. Under Mercury's constitution, Mr Barnes is required to retire before the next Annual Shareholders' Meeting in September 2021 and stand for election by shareholders at that meeting. The Board has determined that Mr Barnes is an independent director for the purposes of the NZX Listing Rules.
