A manufacturer of clever rotor blades for large-size wind turbines announced at Husum WindEnergy 2012 that it has received GL Certification (Germanischer Lloyd) on its prototype 45-meter modular rotor blade, signaling entry into the serial production phase of the company’s growth plan. GL Renewables is part of the GL Group, a body primarily focused on the certification of wind farms, wind turbines, blades, and their components. Manufacturer Modular Wind Energy says its MW45 blade consists of three 15-m sections manufactured at the company’s 170,000 ft2 facility in Huntington Beach, Calif. The sections were shipped to the company’s Rialto, Calif.-based test facility, assembled into a complete blade, and tested between February and June 2012.
Modular Wind Energy produces wind turbine blades featuring a revolutionary structural technology, says the company, that results in longer, lighter, more reliable blades. This lets users offer a lower cost of energy.
The blades feature greater stiffness, strength, and up to 20% lighter design for large blades, enabling larger rotors and ultimately a lower cost of energy compared to conventional blades.
A representative of GL observed each test. Certification involved rigorous static and fatigue testing – proving a 20-year design life for the blade – a significant achievement for any manufacturer. Dr. Myles Baker, co-founder and Chief Technical Officer at Modular Wind Energy, designed the blade.
“This is a tremendous milestone for the company and our blade,” says Dr. Baker. “GL certification is a necessity for doing business in our industry. This certification proves we have a great new technology for the wind industry.” The company is currently in production on its first sets of customer blades, scheduled for installation in the United States later this year.
