  • Wind Energy Production Estimates: Moving Beyond Time Averages

    No need to be a statistician to see that averages are often useful to compare different things. And yet, they often fall short as a true measure of performance. For instance, we use averages to compare the current weather against the climate normals or to get a sense of how our favorite sport team or player is doing. Team (player) statistics are a concise way of combining the scores from many ...

  • Maintenance Manager to control operation and maintenance of offshore wind farms

    Maintenance of wind farms is of increasing importance. Especially in remote areas, where logistics and accessibility are restricted, costs of preventive as well as corrective maintenance form a substantial part of the costs of electricity. The importance of a tool that assists in feedback to the design, failure logging, configuration control and maintenance planning is evident. This paper ...

  • Reactive capability limits of wind farms

    Wind Energy Conversion Systems (WECS) technology can be classified into two main types: fixed speed and variable speed. Fixed speed WECS use an induction generator connected directly to the grid while variable speed WECS use a power converter to connect the generator to the grid. Fixed speed WECS require shunt capacitors for reactive power compensation, while variable speed WECS have reactive ...

  • Vattenfall to invest over €1 billion in North Sea wind farm

    Swedish power giant Vattenfall announced that it will invest more than €1 billion (about $1.4 billion U.S.) in the DanTysk project, a 280 megawatt (MW) offshore wind farm to be located in North Sea waters between Germany and Denmark. Vattenfall has formed a joint venture with Stadtwerke München GmbH (SWM; Munich, Germany) to develop the DanTysk facility, with Vattenfall holding a 51% ...

  • Renewable, clean energy: the petroleum footprint - wind farms under analysis

    This paper presents a methodology to assess projects for the generation of clean, renewable energy. Such methodology is applied here to estimate the consumption of fossil fuels (referred to as 'oil'), required for the construction, operation and maintenance of a wind farm consisting of 97 turbines of 3 MW each. Results show that such consumption represents a conservative 8–9% of the total energy ...

  • Inclusion of biodiesel and PV modules in a wind diesel hybrid system supplying electrical loads on a small farm

    The growing interest in biofuels is a consequence of the need to reduce operating costs of energy systems and the need to reduce emissions of greenhouse gases. The same applies to PV modules, comprising a solution environmentally desirable for power generation. This paper presents a study on the inclusion of biodiesel and PV modules in a system already in operation on a small farm in southern ...

  • Amassing Wind Information

    Wind is a variable resource, but not an indecipherable one. Second Wind encourages harnessing the full range of wind sensing technologies that are available today. When it comes to wind information, much attention is focused on the choice of wind measurement technology and data collection practices in wind resource assessment and project design. Right now, wind data plays a limited role in the ...


  • Measuring Offshore Wind Resources

    To select the right offshore wind site, estimate the future energy output of a wind farm, and determine the best layout for the turbines, project developers must conduct wind resource assessment (WRA) campaigns on site. This is a critical phase of the successful development of wind farms. WRA campaigns on terrestrial sites have traditionally been performed using meteorological towers equipped ...

  • Wind Surpasses Nuclear in China

    Wind has overtaken nuclear as an electricity source in China. In 2012, wind farms generated 2 percent more electricity than nuclear power plants did, a gap that will likely widen dramatically over the next few years as wind surges ahead. Since 2007, nuclear power generation has risen by 10 percent annually, compared with wind’s explosive growth of 80 percent per year. ...
