GERMANY: Senvion will install a prototype of its new 3.4M140 low-wind turbine in Janneby, northern Germany. Senvion will use 68-metre blades on the 3.4MW turbine The 3.4MW turbine, with a 140-metre rotor, is set to be installed by summer 2017, with commercial production expected by the end of that year. Senvion's prototype will be installed with a "sound-optimised blade profile and new pitch-control system", the manufacturer said. The new turbine was launched in September 2015 at the Husum Wind event in Germany. It was released along with three other low-wind turbines in the 3MW range: Vestas introduced its V136-3.45MW turbine, an upgrade to the V126 model; Nordex added a larger capacity version of its N131 low-wind model; and GE launched its low- to medium-wind 3.2MW turbine with a 130-metre rotor specifically designed for the German market. Senvion unveiled an adapted 60Hz version of the turbine for the US market at AWEA's Windpower 2016 this week. Senvion will use 68-metre blades on the turbine, which the manufacturer said could help produce a 20% higher yield than its 3MW, 122-metre rotor machine. The machine is available at two hub heights of 110- and 130-metres. The new turbine will also be fitted with Senvion's 'Next Electrical System' (NES) to help stabilise supply to the grid.
