The structure of this report is as follows: • A timeline of the development of the wind industry in New Zealand. • An outline of the characteristics of New Zealand’s electricity system. Wind needs to be integrated into an electricity system. When considering how wind developed in New Zealand and the issues that have been addressed it is important to have a broad understanding of the electricity system. • Understanding how wind became recognised as being an effective source of generation in New Zealand. • Grid integration. The issue of integrating wind has been a focus of considerable study in New Zealand because of the electrically weak nature of the power system. • Consenting1 issues, such as managing noise, impacts on wildlife etc. • Operations and maintenance. New Zealand’s wind resource is extreme potentially placing significant stress on turbines. • The important role of the New Zealand Wind Energy Association (NZWEA) in helping the industry develop. 1 The term “consenting” means all aspects of environmental planning for windfarms. 1 Timeline of the wind industry in New Zealand • 1970s: University researchers explore New Zealand’s wind resources, including details such as understanding turbulence. • 1970s: Research programme is established

  • Meridian Energy
    NEW ZEALAND Meridian Energy Performance evaluation Meridian Energy equity valuation Macquarie Research’s discounted cashflow-based equity valuation for Meridian Energy (MER) is $6,531m (nominal WACC 8.6%, asset beta 0.60, TGR 3.0%). Forecast financial model A detailed financial model with explicit forecasts out to 2030 has been completed and is summarised in this report. Inside Financial model assumptions and commentary Performance evaluation 2 We discuss a number of key model input assumptions in the report including: Valuation summary 6 Wholesale and retail electricity price paths; Financial model assumptions 8 Electricity purchase to sales price ratio pre and post the HVDC link upgrade; Financial statements summary 18 HVDC link charging regime; Financial flexibility and generation Electricity demand growth by customer type; development 21 The impact of the Electricity Industry Act (EIA) asset transfer and VAS’; Sensitivities 22 The New Zealand Aluminium Smelters (NZAS) supply contract; Alternative valuation methodologies 23 Relative disclosure 24 MER’s generation development pipeline. Appendix – Valuation Bridge 26 Equity valuation sensitivities are provided on key variables. Alternative valuation methodology We have assessed a comparable company equity valuation for the company of $5,179m-$5,844m. This is based on the current earnings multiples of listed comparable generator/retailers globally. This valuation provides a cross-check of the equity valuation based on our primary methodology, discounted cashflow. This valuation range lies below our primary valuation due, in part to the positive net present value of modelled development projects included in our primary valuation. Relative disclosure We have assessed the disclosure levels of MER’s financial reports and presentations over the last financial period against listed and non-listed companies operating in the electricity generation and energy retailing sector in New Zealand.

  • Wind Farm Update April 2008.Pdf
    April 2008 W NNDDFAARMRM ByUUPDATE Dr Julian Elder PDATE he decision on WEL Networks’ proposed wind farm at Te Uku is expected to be Tannounced by the Waikato District Council in the near future. Like you, we keenly await the outcome. I’m sending you this UPDATE to provide important background information as part of WEL’s commitment to on-going consultation with the greater Raglan community. The UPDATE forms no part of the resource consent process. The business case for the wind farm is strong and financially sound. Otherwise, we would not be risking an investment of $200 million, particularly when we are owned by the community. The Te Uku wind farm project will only go ahead if it is profitable. But we do acknowledge that there are residents with mixed feelings about the wind farm, and those who oppose it. The proposed wind farm is among the smaller of the wind farms either in operation or planned elsewhere in New Zealand. The generation of power to meet the growing demands of consumers and industry always presents a dilemma. New Zealanders are demanding renewable energy resources, yet at the same time they are demanding more supply. In the Waikato region, 55 percent more power will be needed in the next 10 years to meet the growth of both residential and business consumers. NO TO NUCLEAR POWER Coal fired power stations are being rejected and no-one supports nuclear power. Other ways to deliver power, such as bio mass, tidal and solar, are not currently realistic in commercial terms. Wind, as an energy resource, continues globally as the most widely accepted form of renewable and sustainable generation.

  • Te Uku Wind Farm, Near Raglan, Are Finding Out
    new zealand wind energy association ›› www.windenergy.org.nz Wind Energy Case Study Business and community opportunities There is more to wind energy than wind turbines and renewable energy. A new wind farm can become a catalyst for business and community renewal, as the people involved with Te Uku wind farm, near Raglan, are finding out. Earthworks at Te Uku wind farm Out towards Raglan, Meridian Energy is developing a new wind “I was just a one-man band but I had to employ staff and learn all farm at Te Uku. This high and windy site has become an important about how to do that. It was a real eye opener but I had lots of help community asset. The wind farm has added a new, positive dynamic from the managers of the construction firms Hick Bros and Spartan to this isolated farming site. Construction,” says Jim. It was a very wet winter, which did not help, but Jim is proud of Business opportunities his contribution. “We all need power at the end of the day.” An important aspect of the construction and ongoing management Local Hamilton firm Spartan Construction together with Hick of the wind farm was that the existing farm operations had to Bros from Silverdale formed Hick Spartan Joint Venture and continue with little or no disruption. That meant that stock and won the contract to supply infrastructure roading, foundations pasture had to be managed along with heavy construction, quarrying and erosion and sediment control at Te Uku. They won the and new roading. Jim Munns, a local fencer played an integral role.

New Zealand purports to protect threatened species primarily with the Wildlife Act 1953, a statute whose purpose is more concerned with wildlife management than implementing a legal framework to protect threatened species. The consensus is that the Wildlife Act 1953 and other applicable legislation such as the Resource Management Act 1991 is not up to the task of protection and recovery of threatened species in New Zealand. In this article we explore how dedicated threatened species legislation in New Zealand might improve on the existing legal framework, and in particular with respect to the designation and planning on threatened species, recovery programmes and habitat protection. For an illustration of how these components may contribute to the threatened species problem we look to Canada as a nation which enacted dedicated threatened species legislation in 2002. The story thus far in Canada suggests legal rules are not a panacea for species decline, but nonetheless dedicated legislation can offer substantial benefits such as transparency and a systematic approach to species planning, better integration with resource development, and a measure of accountability in law to hold public officials to their promises on threatened species protection.
