  • 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 $6,463m (nominal WACC 8.6%, asset beta 0.60, TGR 3.0%). We have assumed, in this estimate, that MER receives $750m for its Tekapo A and B assets. Forecast financial model Inside A detailed financial model with explicit forecasts out to 2030 has been completed and is summarised in this report. Performance evaluation 2 Financial model assumptions and commentary Valuation summary 5 We have assessed the sensitivity of our equity valuation to a range of inputs. Financial model assumptions and Broadly, the sensitivities are divided into four categories: generation commentary 7 assumptions, electricity demand, financial and price path. Financial statements summary 15 We highlight and discuss a number of key model input assumptions in the report: Financial flexibility and generation Wholesale electricity price path; development 18 Electricity demand and pricing; Sensitivities 19 The New Zealand Aluminium Smelters (NZAS) supply contract; Alternative valuation methodologies 20 Relative disclosure 21 MER’s generation development pipeline. Alternative valuation methodology We have assessed a comparable company equity valuation for the company of $4,942m-$6,198m. 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 recent de-rating of global renewable energy multiples (absolutely and vis-a-vis conventional generators). 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.

  • Landscape & Visual Impact Part 5
    Perception and Public Consultation SECTION 14 14.1 Perception People’s perception of wind farms is an important issue to consider as the attitude or opinion of individuals adds significant weight to the level of potential visual impact. The opinions and perception of individuals from the local community and broader area were sought and provided through a range of consultation activities. These included: • Community Open House Events; • Community Engagement Research (Telephone Survey); and • Individual stakeholder meetings. The attitudes or opinions of individuals toward wind farms can be shaped or formed through a multitude of complex social and cultural values. Whilst some people would accept and support wind farms in response to global or local environmental issues, others would find the concept of wind farms completely unacceptable. Some would support the environmental ideals of wind farm development as part of a broader renewable energy strategy but do not consider them appropriate for their regional or local area. It is unlikely that wind farm projects would ever conform or be acceptable to all points of view; however, research within Australia as well as overseas consistently suggests that the majority of people who have been canvassed do support the development of wind farms. Wind farms are generally easy to recognise in the landscape and to take advantage of available wind resources are more often located in elevated and exposed locations. The geometrical form of a wind turbine is a relatively simple one and can be visible for some distance beyond a wind farm, and the level of visibility can be accentuated by the repetitive or repeating pattern of multiple wind turbines within a local area.

  • 2014 – Orléans, France
    Book of abstracts Sponsors The 10th EAWE PhD Seminar on Wind Energy in Europe takes place in Orléans, on the University Campus, from the 28th to 31st of October, 2014. The local organizers, Boris Conan and Sandrine Aubrun, are very pleased to welcome all of you and they hope that you will spend a very pleasant and fruitful stay in Orléans. This seminar provides an opportunity for PhD students and their supervisors from all over Europe to exchange information and experience on research in wind energy, to meet new people and create networks. It is organized and partially funded by the European Academy of Wind Energy (EAWE). The first day of the seminar (28th of October) will be devoted to an introductory day of lectures provided by 'senior' PhD students and/or young Doctors. The goal will be to provide general information to new PhD and to master students on a broad panel of topics related to wind energy. This day will be an occasion for young students to get familiar with the various problematics of wind energy and for the presenters to have a first experience as a lecturer. The last three days (29-31 of October) will be devoted to the conventional PhD seminar. PhD students will present their activities during 20min slots. Some specific sessions will be also devoted to poster exhibitions. The main topics covered by the seminar are: - Materials and structures - Wind, Turbulence - Aerodynamics - Control and System Identification - Electricity conversion - Reliability and uncertainty modelling - Design methods - Hydrodynamics, soil characteristics,
