  • 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 ...

  • Offshore wind installation vessel capacity to tighten after 2020

    The existing fleet of turbine and foundation installation vessels is well suited to serve the European offshore wind market in the short and mid-term but it will not be sufficient to support installation demand after 2020, Michael Guldbrandtsen, senior consultant at MAKE Consulting, told Wind Energy Update. The next 2-3 years will continue to be dominated by orders for jack-up ...

  • Using Lidar for WRA Campaigns: Your Questions Answered (Part I)

    In the course of conversations with wind developers new to Lidar technology, a number of questions seem to come up regularly. In this and future blog posts, I will attempt to answer these questions in some detail to benefit others who might be pondering them as well. Two very practical questions have to do with how WINDCUBE® ...

  • Does Wind Turbine Blade Length Really Matter?

    Simply put: Longer wind turbine blade length means greater power production. Blades capture the wind which forces the rotation of the rotor; longer blades means more area for the wind to push against, which means greater force and rotational power. However, how much difference does blade length make overall, in comparison to other factors? There is a standard formula that can be used to apply the ...

  • Why Levelized Cost of Electricity is an important measurement in wind

    As the wind industry continues to grow, it is faced with much opposition, and a lot of misinformation is being shared. Some of the biggest myths around wind is that the costs of building and installing wind turbines are too high (compared to the costs of other energy sources) and that the industry is overly subsidized. Many anti-wind lobbyists point out that subsidies and tax benefits are the ...

  • Does Ultrasonic Wind Sensor VENTUS-UMB pass extreme tests?

    Sometimes we give our sensors a hard time. But this has a good cause: We want to guarantee the high quality and the keeping of our promises. A few weeks ago, the ultrasonic wind sensor VENTUS was the one to be challenged. We exposed the modern measurement device to extreme conditions. But did it endure these conditions? And where occurs enough wind to challenge the strong sensor at all? Wind ...

  • CSP cost forecasts undervalue benefit to future grid balancing

    CSP generation costs could drop to $77/MWh by 2025 but storage and hybrid solar plants can provide further value by following load, Jose Alfonso Nebrera, Director of Spanish engineering firm ACS SCE, said at the MENASOL 2016 conference on May 26. Global renewable energy expansion is reducing the cost of solar and wind energy while increasing grid intermittency and the need for ...
