2013 NZ Wind Energy Conference 25-27 March, Wellington New wind farm for Wellington… In 2001 four landowners and a long time Ohariu Valley resident formed a plan to farm the wind on their land, west of Wellington. Over ten years on, their idea is coming to fruition as Meridian Energy begins construction of Mill Creek wind farm. The landowners chose wind farming to support the ongoing viability of their farms. They felt it would better preserve the lifestyle and rural character of the area than other options such as housing subdivision or forestry. The 60MW wind farm is located north of West Wind wind farm. Mill Creek shares West Wind’s geography and wind resource. It is expected to slightly outperform the existing wind farm, with a predicted capacity factor of 45% compared to West Wind's 43%. Between West Wind and Mill Creek, Wellington’s wind farms will produce enough electricity to power the equivalent of 100,000 average New Zealand homes – well over the number of houses in Wellington City. Mill Creek will have 26 Siemen’s 2.3 MW turbines. The project is expected to cost $169 million and take 30 months to construct. Full power is expected in mid 2014. Once the project is complete, New Zealand’s wind farms will have a combined capacity of 682 MW and generate 5% of our electricity. The alignment of a number of external factors enabled the project to go ahead - including the strong NZ dollar, an easing of steel prices and highly competitive turbine technology and construction industries.

The excess capacity myth and investment in new generation Eric Pyle, CEO Following Meridian’s Mill Creek announcement, market analysts commented that there is significant excess of electricity generating capacity in New Zealand. With demand flat, why build new generation? Markets should encourage innovation and drive least-cost solutions. In the electricity sector this means lower cost generation is used instead of higher cost generation. This happens on an hourly basis in New Zealand’s electricity market. This does mean there will be excess capacity as more expensive generation is replaced over time by lower cost generation. If wind is genuinely the most cost-effective form of new generation and has a lower cost of energy than some existing generation, then wind generation will be built. The more expensive generation will be used less and less until it is retired. In this light, the excess capacity is simply a shift to the most cost-effective generation at the time and a product of a well-functioning market. Analysis of 2010 data by Deloitte indicates that wind is being developed for as lows as $78/MWh in NZ, which is competitive with the costs of other forms of generation. The general view in the wind industry is that costs have reduced since that analysis was completed, and will continue to do so as turbine technology continues to improve. Some very interesting analysis from the US National Renewable Energy Laboratory and the International Renewable Energy Agency (IRENA) highlights that the cost of energy (expressed as dollars per megawatt-hours) from wind turbines is falling, and more notably so when the cost of raw materials, such as steel, is levelised. The key point from the analysis is that the amount of energy able to be produced is increasing for any given site as a result of improvements in technology. The impact of improving technology is positive for the bottom line of wind farm developers – the cost of energy is reducing, all other factors being equal. Gamesa for example has publicly stated that it expects the cost of energy from wind turbines to reduce 30% over the next three years as a consequence of turbine improvements. So, should we be worried about overcapacity? No. Avoiding overcapacity would imply a return to the good old days of electricity shortages in dry years, potential blackouts, increasing prices and the inevitable political interference to ‘fix’ the problem. Remember those good times? Rather than a problematic excess of capacity, perhaps we are seeing the electricity market working coupled with fundamental changes to the costs of generation. New wind farms are one sign of this, signals that the coal units at Huntley will be phased out are another sign. Read more: Ireana report: Renewable Energy Cost Analysis - Wind Power IEA report: The Past and Future Cost of Wind Energy Electricity generation trends Wind generation continues its upward trend according to recent The Ministry of Business, Innovation and Employment’s (MBIE, formerly the Ministry of Economic Development) energy publications. New wind farms resulted in a 19% jump in wind generation during the 2011 calendar year, according to the 2012 edition of the Energy Data File, It also notes that wind generation has grown at an average of 30% annually over the last decade. Record low water inflows into the South Island have resulted in an overall drop in renewable generation this year. The latest Energy Quarterly reveals that the renewable share of electricity generation dropped to 64% during the June 2012 quarter. Hydro output and total electricity demand in the June 2012 quarter were similar to the last dry year in 2008, however renewable generation was boosted this quarter by new renewable generation. The Energy Quarterly states: “the increased geothermal and wind generation commissioned in the last few years encouraged a 17% drop in the generation required from gas and coal in the June quarter when compared to the June quarter of 2008.” which is the lowest share since the June 2008 quarter of 2008 when renewables made up just 56% of generation under similar conditions.

The application was directly referred to the Environment Court at Meridian’s request and with the agreement of the Hurunui District Council and Canterbury Regional Council. Wind on Stewart Island? Venture Southland is investigating options for renewable power generation on Stewart Island. Diesel is used to generate electricity currently one Stewart Island, which results in much higher electricity prices than elsewhere in NZ. A similar situation led to the development of a small wind farm in the Chatham Islands.

  • Evolving the Electricity Market to Optimise New Zealand's Renewable
    Evolving the electricity market to optimise New Zealand’s renewable potential New Zealand could have the greenest grid in the world - that was the view that Kieran Devine, System Operator at Transpower, presented at an NZWEA workshop in October. The aim of the workshop was to consider how the electricity market could be evolved to accommodate the changing profile of electricity generation in New Zealand. The electricity market operates under rules that were established to optimise the use of water and fossil fuels for electricity generation. But since the rules were established, technology has evolved. Wind and geothermal are making a growing contribution to generation, predominantly because they are the cheapest options for new generation. Computing power has improved – meaning the computers behind the electricity system can do more in less time. And we are only beginning to see the potential of demand-side management. The market rules need to evolve to accommodate changes in the market and future trends, so that the grid – and therefore New Zealanders - can get maximum benefit from the technologies that are operating in the electricity system. Currently wind generation is “bolted on” to the electricity market. Wind is offered in at 1 cent and so is a price taker. However, if wind were to operate at the margin, as a price setter, investors may well be able to achieve a better return on their investment in wind farms. At the same time, wind farms could be designed and operated in a way that contributes positively to grid stability. The question is what would this actually look like? Providing ancillary services is one way that wind farms can contribute to grid stability.

  • Wind Farm Consent Conditions After NZS6808:2010
    Proceedings of ACOUSTICS 2016 9-11 November 2016, Brisbane, Australia Wind Farm Consent Conditions After NZS6808:2010 M Miklin Halstead Marshall Day Acoustics Limited, Wellington, New Zealand ABSTRACT In New Zealand, commercial scale wind farms require resource consents where environmental effects, including noise, are considered. Conditions of consent prescribe noise limits and management and assessment methodologies which apply to the project under consideration. As experience with wind farm noise has accumulated, these conditions have become more complex. In 2010, the second edition of New Zealand Standard NZS6808 was released, which included a model set of conditions intended as a simple and robust set of requirements, when used in conjunction with the standard itself. This paper examines the degree to which subsequent wind farm consents have adopted and relied upon the Standard and the model conditions, and considers whether additional consent conditions that have been included point to matters which should be incorporated into the next edition of the standard. 1. INTRODUCTION In New Zealand, all commercial scale wind farms require resource consents. This requires that issues including noise effects be fully considered, and provides an opportunity for local authorities or the courts to impose specific controls on noise emissions which are suited to the particular wind farm application. The history of New Zealand’s wind farms stretches back to 1993, and over that time noise emissions have shifted to the forefront in wind farm resource

  • Wind Energy Industry Impacts in Oklahoma November 2015
    RESEARCH FOUNDATION REPORT Wind Energy Industry Impacts in Oklahoma November 2015 Prepared by Dr. Shannon L. Ferrell and Joshua Conaway, Oklahoma State University Department of Agricultural Economics Acknowledgments This project represents an unprecedented collection of data about the Oklahoma wind energy industry, and would not have been possible without the assistance of a number of state and county personnel who went far above and beyond their duties in assisting with the collection and analysis of this information. Ms. Kylah McNabb with the Oklahoma State Energy Office was incredibly generous in sharing information she had compiled over the course of 12 years regarding Oklahoma’s wind energy industry and also shared the benefit of her experience as a wind resource researcher and project developer. Her assistance was absolutely vital to compiling the portrait of Oklahoma’s wind energy industry presented in Section 1. Importantly, though, Ms. McNabb’s assistance was foundational to the project team’s understanding of all the issues researched through this project. Compiling the historical ad valorem tax data and building a sound ad valorem forecast model – the core of this report’s Section 2 – would have been impossible without the assistance of Gary Snyder (OSU Center for Local Government Technology Assessor Training Accreditation Program), Wade Patterson (Garfield County Assessor), Doug Brydon (Deputy Director of the Oklahoma Tax Commission’s Ad Valorem Division), and Dr. Notie Lansford (Director of the OSU County Training Program). Each made contributions of advice, experience, insight, data, and personal contacts enabling our project team to collect an exhaustive dataset on wind energy system ad valorem tax revenues over 20 counties and to build the forecast model.

  • Excerpts from the Final Report of the Township of Lincoln Wind Turbine Moratorium Committee
    EXHIBIT 5 Excerpts from the Final Report of the Township of Lincoln Wind Turbine Moratorium Committee [Prepared by Elise Bittner-Mackin for presentation to the Bureau County, Illinois, Zoning Board of Appeals regarding the 54.5-MW 33-turbine Crescent Ridge wind facility proposed for Indiantown and Milo by Stefan Noe (Illinois Wind Energy)] After the wind turbines went online in Kewaunee County, Wisconsin, the Lincoln Township Board of Supervisors approved a moratorium on new turbine construction. The purpose of the moratorium was to delay new construction of wind turbines for eighteen months, giving the township the opportunity to assess the impacts of the 22 turbines installed by Wisconsin Public Service Corporation (WPSC) and Madison Gas and Electric (MG&E), which went online in June 1999. The following document summarizes some of the problems the Moratorium Committee faced in trying to address problems the township hadn't faced prior to turbine construction and some of the resulting changes the committee proposed as a result of its study. Verification of this information can be obtained from Lincoln Township officials. Agenda. The Moratorium Committee met 39 times between January 17, 2000, and January 20, 2002, to (1) study the impact of wind factories on land, (2) study the impact on residents, and (3) review conditional use permits used to build two existing wind factories in Lincoln Township. Survey. The committee conducted a survey on the perceived impacts of the wind turbines that was sent out to all property owners residing in the township. Each household received one vote. The results were presented on July 2, 2001, to the town board, two years after the wind factory construction.
