First Wind helps Burlington Electric source 92% of its power from wind

  First Wind, an independent U.S.-based renewable energy company, has announced that the company has reached an agreement with Burlington Electric Department (BED) to sell the utility power generated from the planned Hancock Wind project near Ellsworth, Maine. BED is seeking to source 100% of its supply needs from renewable energy.  The addition of the


Seven ways floating turbines could solve offshore windpower conundrums

A floating turbine that avoids migratory bird patterns, NIMBY activists, and state jurisdictions, according to American Offshore Energy. The Pennsylvania-based company says its vertical-axis wind turbine (VAWT) uses tension and compression design principles, which allow a stiff, lightweight, fixed-wing-composite structure that can be scaled to huge sizes, and could one day bring consistent renewable energy

A closer look at wake loss modeling based on production data

Matthew Breakey/Wind Resource Engineer, P. Eng / Wind Energy Errol Halberg/Manager of Wind Resource Assessment, P. Eng / Wind Energy, GENIVAR Inc., www.genivar.com Wake validation studies show that a single-turbine wake model under-estimates the wake for turbines affected by multiple turbine rows. A wake combination method, however, can improve the accuracy of wake modeling in

At 270 metric tons, the company says 5 MW offshore unit is light enough for a monopole mounting, an advantage in the offshore market where some 5-MW units have been mounted on large and complex four-legged structures. 97% availability is one design goal.

Gamesa launches a 5 MW offshore turbine

Spanish wind-turbine manufacturer Gamesa recently launched an enormous 5 MW turbine on the windy coast of Las Palmas in the Canary Islands, a Spanish territory. Although a somewhat larger version of its 4.5 MW turbine, the company says it boasts several improvements such as modular components and redundant control systems. The blades, manufactured at a

A novel way to store excess wind power: as H2 in gas lines

A developer and manufacturer of hydrogen generation and hydrogen-based power modules says that E.ON has inaugurated commercial operations at its Power-to-Gas (P2G) facility in Falkenhagen, Germany. The plant uses wind-powered electrolysis equipment from Hydrogenics Corp, (www.hydrogenics.com) to transform water into hydrogen, which is then injected into the existing regional natural gas transmission system. The hydrogen,

CG transformer certified for offshore windpower

Transformer manufacturer CG has received certification from GL Renewables Certifcation (GL RC) for its liquid immersed SLIM and Bio-SLIM distribution transformer. The hermetically sealed transformer is also available with a bio-degradable transformer fluid which reduces the risk of pollution at environmentally sensitive locations, such as offshore. The certification was carried out according to GL’s Guideline
