Turbine manufacturer ENERCON has successfully installed EP4-126 4.2MW turbine at a site in the Netherlands. Operation of the Wind Class IIA WEC prototype is the first machine based on ENERCON‘s new 4-MW platform (EP4), and the forerunner for the E-141 EP4 (low-wind turbine) announced for the end of this year.
“The launch of the prototype took place according to schedule,“ says ENERCON Managing Director Nicole Fritsch-Nehring.
The EP4 platform unites innovative technology and intelligent modular design, uses more identical parts and standard components, and provides customers with the highest quality standards and maximum efficiency and reliability for a multitude of sites.
The new E-126 EP4 can achieve an annual energy output of approx. 14.8 million kilowatt-hours at inland sites with an average wind speed of 7.5 meters per second with a 135-m hub height.
Except for its longer rotor blades, the components of the E-141 EP4 are almost identical to the E-126 EP4. The E-141 EP4 is designed for Wind Class III and has a rotor diameter of 141 m, which is currently the world‘s largest onshore rotor on the market.
At locations where the average wind speed is 6.5 m per second, the machine is expected to generate an annual energy output of more than 13 million kilowatt-hours.
Parallel to the installation of the EP4 prototype in Lelystad in the Netherlands, preparations began for serial production scheduled to be launched around the middle of the year. By the end of 2016, pre-series machines will be produced followed by serial turbines at the beginning of 2017.
