ENERCON and partner Lagerwey have developed two new wind turbines based on Lagerwey’s LP4 platform.
Like ENERCON’s new EP3 turbines, the new L147 LP4 and L160 LP4 for wind class IIA and IIIA sites (IEC) are based on a compact design.
“With these turbines, we are bringing the compact design into the 4 MW-plus segment, and offering our customers around the world more attractive options for their projects”, says ENERCON Sales Director Stefan Lütkemeyer.
The L147 LP4 will be given a permanent magnet generator (PMG) with a nominal power of 4.3 MW and a rotor diameter of 147 metres. The L160 LP4 will also be developed with a PMG which will have a nominal power of at least 4.0 MW. Its rotor diameter measures 160 metres. Both types of wind turbine will be directly driven. At sites with an average wind speed of 7.5 m/s, the L147 LP4 will produce annual energy yields of around 17.2 million kilowatt-hours. The aim for the L160 LP4 is an annual energy yield of at least 14.8 million kilowatt-hours at 6.5 m/s.
The series production version of the L147 LP4 will be available with steel towers and hub heights of 126 or 155 metres, and that of the L160 LP4 with steel towers and hub heights of 120 or 166 metres. Lagerwey’s modular steel tower concept (MST) will be used in both of the new developments in place of conventional tubular steel towers.
The L147 LP4 prototype is scheduled to be installed in Germany by the end of the year. The prototype of the L160 LP4 is set to follow in Q4/2019. Series production of the L147 LP4 is also envisaged to begin as early as next year. ENERCON and Lagerwey intend to go into series production with the new L160 LP4 in 2020.
In Octobert this year, ENERCON reached a 50GW milestone for its wind turbines. The global installed capacity record was achieved at the beginning of October during installation of wind energy converters for the Mui Dinh project in Vietnam. ENERCON’s global balance of installations currently amounts to more than 29,075 wind energy converters (WECs) with an installed total capacity of over 50,027MW. At this time, the company is installing sixteen E-103 EP2 WECs in the Mui Dinh wind farm for its customer eab New Energy GmbH. Together with the Trung Nam wind farm, built at the same time, the project marks ENERCON’s entry into the Vietnamese market.
“Our installed wind energy capacity across the world now replaces the electrical power from more than 50 coal-fired power plant units,” says Lütkemeyer. “This makes a significant contribution to global climate and environmental protection. We’ve got a long way to go yet: climate change has not been averted, global demand for energy is rising. Demands are therefore still placed on the onshore wind energy sector to play its part in switching energy systems over to the necessary 100 percent renewable generation. We will not relax our efforts to push forward with the energy transition across the world, and also take account of areas such as transport and heating with our innovative products and solutions for integrated energy,” he said.
