Boulder Expands
Product Portfolio

Boulder Wind Power (BWP), a developer of permanent-magnet generators and full power converter technology for utility-scale wind turbines, has expanded its product portfolio for onshore and offshore applications.

Originally focused on developing and testing core technology for direct-drive turbines, Colorado-based BWP says it now offers solutions for geared turbines in addition to more direct-drive products.

Among the new offerings is BWP’s Ultra Low Speed generator category designed for onshore, low-wind speed sites where noise constraints limit aerodynamic rotor tip speed and, ultimately, the aerodynamic rotor diameter. BWP says this new category applies the benefits of its Low Speed generator but adds lower speed ratings and higher torque.

The expanded portfolio details the product variants within each generator line for Medium Speed (1.6 MW to 7.7 MW), Low Speed (1.0 MW to 7.5 MW) and Ultra Low Speed (1.0 MW to 5.3 MW). Recognizing the need for increased turbine ratings for offshore markets, BWP says it is also developing geared and direct-drive generators for 12 MW turbines, which will be released later this year.

The product portfolio also features BWP’s power conversion systems, including the company’s 500 kW modular back-to-back power converter.

“Our technology portfolio enables an air core generator architecture that has significant advantages as generator torque ratings grow,” says Andy Cukurs, CEO of BWP. “Instead of limiting this to direct-drive applications, we’re expanding the product configurations to meet the complex needs of many wind turbine manufacturers.”

DNV GL Recognizes
Goldwind Design

DNV GL has recently completed an evaluation for a 2.5 MW wind turbine designed by China-based Goldwind. According to DNV GL, it has confirmed that the turbine meets the requirements according to the standard IEC 61400-22 and IEC 61400-1 of the International Electrotechnical Commission (IEC).

Goldwind gained the design verification over a period of 10 months.

German Firm
Enters U.S. Market

EWC Weather Consult GmbH, a German weather service provider, plans to enter the U.S. market and present its wind and weather data management solutions to wind power developers in the country.

The company plans to launch its “measure correlate predict” process for wind measurements along with a simulation tool for virtual expansion scenarios using renewable energies. The company says the wind potential analysis, which is already established on the German market, will now be complemented with comprehensive wind and yield time series in the U.S. as well.

Gamesa Launches
Anti-Icing Paint

Gamesa has developed Bladeshield, an anti-icing paint solution for wind turbines. The company says the new system is apt for use in its own 2.0 MW-2.5 MW and 5.0 MW onshore and offshore platforms, as well as in other manufacturers’ products, and also features anti-erosion and durability properties optimized for cold regions.

The Bladeshield system is the result of three years of research under the broader Azimut project for the development of offshore technology, which was sponsored by Spain’s Centre for the Development of Industrial Technology.

In addition to Bladeshield, Gamesa recently unveiled two systems for detecting and eliminating ice on blades that have been developed for Gamesa’s suite of 2.0 MW -2.5 MW turbines. The company says it is also developing another ice-prevention system in collaboration with Finnish technology provider VTT for its platform of 5.0 MW turbines.

Strong-Wind
Versions Unveiled

Enercon has announced plans to launch strong-wind versions of its E-82 and E-101 series wind turbines.

Both turbines were originally available as Class II versions, but the new Class I E-82 will have a rated capacity of 2.35 MW, while the new E-101 will have a rated capacity of 3.05 MW.

Enercon says the strong-wind versions are primarily destined for export markets. The company plans to make the new E-82 available in 2015 and the new E-101 available in 2016.

Northstar Licenses
Turbine Tower IP

U.S.-based Northstar Endeavors LLC, dba Northstar Wind, has granted Alphatec Nordeste the exclusive license to design, manufacture, construct and sell wind towers using Northstar’s intellectual property (IP) in Brazil.

Northstar says its Northstar Modular Tower design provides the megawatt wind industry a solution to build taller towers at heights up to 140 meters, and Alphatec will be expanding its energy-related businesses by developing towers utilizing Northstar’s IP. Alphatec is also building a dedicated manufacturing facility for the towers and tower components, which is scheduled to come online in 2016.
