In its action plan - Energy 21 - the Danish government has decided that a Danish island as a demonstration project should become self sufficient from renewable energy sources, including transportation, within 10 years. In November 1997 the Danish island Samsoe was officially selected - among 5 candidates - to become a REI. The Danish REI is a good starting point for global co-operation among similar initiatives to exchange experience and information and to plan and implement collaboration programmes. The Danish Council for Sustainable Energy, which is an independent council for advising the Danish government and parliament in connection with the implementation of Energy 21, has initiated this review of REI. The council considers that the government's idea of a Danish REI is a useful way to make future energy-systems visible and concrete and to implement and demonstrate models that can be used, not only on islands at home and abroad, but in principle everywhere. If politicians should be inspired to aim for a broader use of renewable energy as part of a sustainable development, it is necessary to demonstrate renewable energy in a large scale and in an integrated and organised from, placed in a well defined area - as e.g. a smaller island. To look further into this matter, it has been decided to elaborate this report, to be used as a tool for future co-operation. The Danish Council for Sustainable Energy has furthermore decided to organise an international REI-conference in 1999. The purpose of this report as well as the conference of 1999 is to prepare for future global co-operation and networking among REIs. On behalf of the Council for Sustainable Energy, Lars Davidsen Member of the Danish Council for Sustainable Energy 3 Renewable Energy on Small Islands First Edition April 1998 PREFACE BY THE AUTHOR This is the first edition of the report and there will be a new addition in the Spring 1999.

Summary of Main Findings 1.1 The Island Energy Issues Even though there are conditions, which separate islands from each other the "island factor" is present - circumstances, which are unique to islands compared to the mainland (or large islands). They face a series of shared difficulties, needs and problems. Some of the characteristics of the "island factor" are: · insularity · a limited range of resources · small markets · specialisation of economies · diseconomies of scale · fragility of eco-systems The majority of islands also have some circumstances in common regarding energy - particular problems regarding production and distribution of energy. The island energy issues are characterised by: · major reliance on imported fossil fuels · small-scale generation of electricity · high distribution costs · under-use of renewable energy resources in comparison with the potential · integration of renewable energy sources in most island cases is an economically feasible solution qua their relatively high energy prices Most small islands around the world today are dependent on imported fossil fuels for the majority of their energy needs especially for transport and electricity production. For reasons of scale and isolation, infrastructure costs (including energy) are higher. For small islands the costs of fossil fuels are usually equivalent to a substantial proportion of the total value of imports. It has e.g. been estimated that energy often accounts for more than 15% of all imports in the islands in the European Union. Fuel imports are thus a great drain and a significant constraint on development - they crowd out vital capital and social expenditures and inhibit the achievement of much needed growth. Successful efforts by islands to reduce energy imports, either through the achievement of energy efficiency or the use of locally renewable energy resources, could therefore make a significant contribution to economic development. As it is specified by the European Islands Energy and Environment Network (ISLENET): "It is in the interest of islands to engage in policies, which favour the promotion of energy management. That is to say, they should consider in their energy planning, the promotion, on the one hand, of energy efficiency and energy saving actions, whilst on the other hand, they 5 Renewable Energy on Small Islands First Edition April 1998 should seek to develop, where appropriate, renewable energy sources as means of power. There are of course many obstacles, which impede the development of energy management in islands, however, experience proves that the advantages outweigh the disadvantages". 1.2. Renewable Energy Islands The table below summarises some of the findings on the use of renewable energy on selected small and medium islands. In the table the islands are specified regarding: · name · size of population · area · percentage of total energy demand from renewable energy sources · percentage of total electricity production from renewable energy · percentage of installed electricity capacity from renewable energy sources · if the island has an renewable energy plan (REP) · renewable energy sources (RES) most utilised today The following should be kept in mind when reading this table: · the islands are prioritised in regard to the percentage of electricity production coming from RES.

    143 Environmental Assessment 10.2 Communication Impacts 10.2.1 Background Wind turbines have the potential to interfere with television and radio broadcasting, mobile phone reception, microwave links and other radio links such as mobile and CB radio. There are three mechanisms by which wind turbines may cause interference: reflection or scattering, diffraction and near field effects. • Reflection or scattering – occurs when a signal becomes obstructed between the transmitter and a receiver, this could be due to a tower or moving blade component as shown in Figure 10-5. • Diffraction – occurs when a signal is both absorbed and reflected by an object in the signal path. • Near field effects – are caused by electromagnetic fields. This is no longer an issue due to advances in wind turbine technology and compliance with Electromagnetic Emission Standards. A communication impact assessment report was prepared by Epuron. The objectives of this investigation were to identify the potential for impacts from the proposed White Rock Wind Farm on existing telecommunications services in the vicinity of the project, and to identify appropriate mitigation strategies for potential impacts. The full investigation including a glossary of acronyms used in the investigation, maps, footnotes and references is presented in Appendix 6. The following approach was adopted to identify the potential impact of the project on telecommunications: • Identify holders of telecommunications licenses (under the Radiocommunications Act 1992) within a 25km radius of the project, as well as point-to-point links in the vicinity of the project, using information provided on the Australian Communications and Media Authority (ACMA) RADCOM database. • Provide written notification of the project and seek comments from each license holder identified via the ACMA RADCOM database search.

  • Windflow Technology: Interim Report 2010
    Windflow Technology: Interim Report 2010 Overview – Windflow’s major achievements in the first half of the 09/10 financial year were: • Installing and commissioning the remainder of Stage 3 to take Te Rere Hau (TRH) wind farm to a total of 65 turbines. • Delivering TRH turbines operating availability to above 93% for calendar 2009, and starting 2010 above 95% availability. • Submitting (as part of International Electrotechnical Commission (IEC) Type Certification) the final documents to Lloyds Register in Britain for Class 1A Design Evaluation of the Windflow 500. • Gaining resource consent to develop the 25 turbine Long Gully wind farm in Wellington. Financial Results - Windflow continued to produce a positive gross profit for the half year. Consolidated revenue for the six months was $13.597 million (compared with $11.834 million for the previous comparable six month period). Direct production costs including turbine costs for the same period were $12.694 million (compared with $10.841 million for the previous year) resulting in a gross profit of $0.903 million for the period compared with $0.993 million for the previous year). The result is that Windflow has recorded a half-year loss of $1.628 million (compared with $ 1.082 million last year). Cash held at 31 December 2009 was $2.034 million, a reduction of $9.693 million for the six months. The reduction in cash held is attributable to an anticipated cash outflow during the latter stages of production, the dispute with NZ Windfarms, and some production related timing impacts. Windflow expects to generate a cash surplus from operations over the coming period with a corresponding improvement in its cash position.

It will convert the old, conventional economy into a new, sustainable economy that is environmentally sound, economically viable, and socially responsible. Therefore, there is a need for quick actions by everyone who wants to move toward energy-efficient development and new environmentally friendly behavior. This can be achieved by setting specific guidelines of how to proceed, where to start, and what knowledge is needed to implement such plans and initiatives. This paper seeks to contribute to this very important issue by appraising the ability of full-scale implementation of RES combined with energy storage in an island power system. The Greek island power system of Astypalaia is used as a case study where a battery energy storage system (BESS), along with wind turbines (WTs), is examined to be installed as part of a hybrid power plant (HPP). The simulation’s results showed that the utilization of HPP can significantly increase RES penetration in parallel with remarkable fuel cost savings. Finally, the fast response of BESS can enhance the stability of the system in the case of disturbances.

No entanto, é off-shore e a elevadas altitudes que o vento é mais forte e, sobretudo, mais consistente. Neste contexto, soluções inovadoras no âmbito dos AWES têm vindo a ser apresentadas. Com esta dissertação pretende-se estudar um destes sistemas, que envolve um kite ligado a um gerador através de um cabo. À medida que o kite se eleva por força do vento, o cabo é desenrolado, fazendo acionar o gerador, produzindo assim energia. Posteriormente, o cabo é recolhido e, de seguida, o processo repete-se. O sucesso destes sistemas é suportado pelo facto de que a força de lift do kite é proporcional ao quadrado da velocidade aparente do vento. O objectivo principal desta dissertação é desenvolver um algoritmo de seguimento de trajetória que permita ao kite seguir um caminho pré-definido durante a fase de produção. A trajetória deve ser definida de forma a que o kite se mova maioritariamente numa direção perpendicular à velocidade do vento, maximizando assim a produção de energia. Neste contexto, o modelo dinâmico 3D do Kite é descrito. De seguida, são realizadas simu- lações com versões 2D simplificadas do modelo, com o objetivo de o validar.
