The technology you need – wherever you need it Maximising compliance – around the world With a Vestas permanent magnet generator and a full scale converter, the 2 MW GridStreamer™ complies with even the most challenging grid requirements of the modern energy market. Protecting your investment by safeguarding the technology is important to us. In the event of lost grid connection, excess power is converted into heat in resistors, sparing the drive train components any unnecessary loads. The power system delivers a power factor range of +/-0.9 at full power. Just like the wind, the world energy market moves fast. The 2 MW GridStreamer™ allows you to respond rapidly to new and changing grid requirements with the added confidence provided by proven Vestas technology. Lowering Cost of Energy Our 2 MW GridStreamer™ turbine further lowers your cost of energy through lower foundation, erection and grid connection costs. Less substation equipment and fewer STATCOMs means not only less equipment to purchase, but also less to install and maintain.

Hi-tech engineering designed for greater profitability Cooling the cost of temperature regulation Heat control is an important feature for running your wind turbine smoothly and efficiently. Our CoolerTop® technology, which comes as standard with all our 2 MW GridStreamer™ turbines, helps moderate optimum operating temperatures within the turbine, even at high ambient temperatures and altitudes. This ability opens up whole new areas of land once considered unsuitable for wind turbines – even ones near populated areas – due to its minimal noise impact. The absence of electrical components and moving parts means it needs little servicing – assuring you of ultimate efficiency and yet lower running costs. Furthermore, our 2 MW GridStreamer™ can operate at anything between -30°C and 40°C. Affordable to install - easier to maintain We also use anchor bolts in our foundation design, which allows faster erection on -site and simpler tower realignment. We have streamlined our design to minimise the number of individual parts, making our equipment more efficient than ever to run and repair. for example, the permanent magnet generators do not use slip rings and brushes, which are susceptible to wear and tear thus reducing scheduled downtime for maintenance. We know that the more time your turbine spends in operation, the greater your profits. We are constantly improving the efficiency of our range to help you achieve your commercial targets. Scaling new heights of adaptability The upgraded turbines have been certified for high-altitude operation up to 2,000 meters and may be installed at higher altitudes, depending on site-specific conditions.

Safeguarding your investment, powering your profits Enviable track record for dependability Vestas’ reputation for reliability makes the 2 MW GridStreamer™ turbines a low-risk choice for investment. It is a distinction of which we are immensely proud. Since 1999 we have installed more than 9,700 2MW turbines globally, all of which incorporate the major features employed in the 2 MW GridStreamer™ range – including the pitch, yaw and control systems, and the drive train. This rigorous ‘in the field’ testing means that our customers can be confident in the longevity of our equipment. Also, customers can confidently deploy a modular fleet of efficient and fully grid compliant 2 MW GridSteamer turbines for optimal performance across all wind classes and site conditions. Over 46,000 Vestas turbines are now generating power and revenue around the world. Using some of the industry’s most stringently-tested components and systems, we have learned how to minimise downtime and maximise returns on investment, underpinning the whole spectrum of business scenarios.

Full control through service experts and our surveillance system Surveillance, maintenance and service Operating a large wind power plant calls for efficient management strategies to ensure power production is uninterrupted and to control operational expenses. Vestas provides 24/7 monitoring, performance reporting and predictive maintenance systems to improve turbine performance and availability. Predicting faults in advance is essential to this effort, helping to avoid costly emergency repairs and unscheduled interruptions to energy production. The optional Vestas Condition Monitoring System (CMS) assesses the status of the 2 MW turbines by analysing vibration signals. For example, by measuring the vibration of the drive train, it can detect faults at an early stage and monitor the progress of any damage. This information allows the service organisation to perform required maintenance before the component fails, reducing repair costs and production loss. Additionally, our Active Output Management® (AOM) concept provides detailed plans for service and maintenance, online monitoring, optimisation and troubleshooting. It is even possible to get a full availability guarantee, under which we compensate you if the turbine fails to meet agreed availability targets. Vestas Online® Business All Vestas wind turbines benefit from Vestas Online® Business, the latest Supervisory Control and Data Acquisition (SCADA) system for modern wind power plants. This flexible system includes an extensive range of monitoring and management functions to control your wind power plant in the same way as a conventional power plant. Vestas Online® Business enables you to optimise production levels, monitor performance, and produce detailed, tailored reports from anywhere in the world. The system’s power plant controller provides active and reactive power regulation, power ramping and voltage control.
