  • Wind energy in Norway - Icing of wind sensors? Not with the ultrasonic wind sensor VENTUS! - Case Study

    Renewable energy in Norway is getting more and more important! The government has spent the goal that the use of renewable energy should increase strongly over the next years. Wind power plays a major role in this endeavor. Norway is climatically and topographically one of the most interesting locations for wind energy in Europe - but it is barely tapped by now. Our customer, the power company ...

  • Mechanical vs. Ultrasonic Anemometers for Wind Turbine Control

    What do you think? Does the replacement of mechanical wind sensors trough ultrasonic anemometers in wind turbine control pay off after less than a few years? Free Cost Benefit Analysis about Replacement of Mechanical Wind Sensors Anemometers are vital components of utility-scale wind turbines and determine the performance of the turbine’s ...

  • Offshore Wind Versus Solar in the Eastern US: An Unexpected Rivalry

    Less than a decade ago, offshore wind energy and solar PV were similarly priced energy sources. Unsubsidized installed costs for both exceeded $5 per watt, or more than double that for land-based wind. Despite their cost, both technologies were seen as the best hopes for supplying urban centers with green power, especially in the BOSNYWASH (Boston-New York-Washington, DC) corridor of the eastern ...

  • Africa’s green energy challenge: Mega projects, off-grid or somewhere in between?

    South of the Sahara, getting electricity to 620 million people may require an all-of-the-above strategy. A 310-megawatt wind farm sprouting up in a remote, barren landscape near Lake Turkana in northern Kenya has the clean energy world buzzing — and for good reason. Africa’s largest wind farm, with 365 towering turbines, is creating more than 500 stable jobs in an ...

  • 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 ...

  • What’s the Future of R&D in the Wind Industry?

    When the wind industry finally reacted to the world’s financial crisis—it didn’t fully hit us until 2010—at once, we lost both an incredibly vibrant global wind market and sufficiently robust profit margins. The market recovery is rebounding nicely now, thanks largely to government incentives, but profit margins will probably never fully recover—at least, not to the ...

  • Wind turbine controlling of the future

    Higher, more robust, more reliable: Parallel to the growing requirements for wind turbines, the requirements for monitoring sensors grow as well. But how can wind sensor manufacturers fulfil these wishes? And how should a future wind sensors look like? After analysing the current conditions and trends on the wind energy market, our CEO Klaus Hirzel compiled a wish list for future wind sensors. ...

  • Power curve measured and verified – Case Study

    In 2010 RSE SpA (Energy System Research Inc.) within a Program Agreement with the Italian Ministry of Economic Development started a measurement campaign on a Libellula wind plant installed in Tuscany. The campaign lasted 1 ½ years and during this time RSE measured the turbine’s power curve following the requirements of the relevant IEC Standard ...

  • Animation: How Wind Turbines Work

    The windmill, which converts wind into rotational energy to mill grain or pump water, has been around since antiquity. It’s even been claimed that Ancient Babylonians planned to harness wind as early as almost 4,000 years ago, as part of a scheme for one of Hammurabi’s ambitious irrigation projects. By the end of the 19th century, wind energy took on a whole new meaning as engineers ...

  • No Place Is Too Far

    The remote location of hydropower stations is often a great challenge when major repair work is necessary. The refurbishment of a large generator in the Scottish Highlands shows how Sulzer finds cost-effective service solutions even in places miles from nowhere. Much of the UK hydroelectric capacity was built during the 1950s. These installations have performed extremely well, especially ...
