Coordinated turbine yaw adjustments based on advanced data analytics could increase annual energy production by several percentage points, initial findings from a joint government-industry research project show.
About 15-20% of the wind energy projects installed in the United States since 2000 could be repowered to capture federal tax after the extension of the production tax credit (PTC), said Kevin Smith, director, Asset Management & Operating Services at the Renewables Advisory within DNV GL – Energy.
Cold climate and de-icing technologies are improving the business case for wind power in Canada, but icing prediction and assessment remain problematic for the industry, experts told Wind Energy Update.
Using drones that follow automated flight paths without the need for a human pilot could allow wind farm project teams to inspect up to twice as many turbines in a day as they can today, experts told Wind Energy Update.
Emerging oil filtration techniques could minimize pad-mount transformer faults and reduce one of the biggest sources of wind farm balance-of-plant (BoP) maintenance, Judah Moseson, vice president of operations at service provider Cooke Power Services, told Wind Energy Update.
Improving wind turbine reliability to 99.5% will require new data analysis approaches across the industry as existing techniques won’t allow the sector to go above current reliability levels, according to Carsten Westergaard, senior advisor, Wind and Water at the Sandia National Laboratories and Professor of Practice at Texas Tech University.
Switching to self-performance of wind farm operations and maintenance (O&M) at end of warranty can cut costs by between 25% and 35% and allow operators to make more design improvements to increase unit reliability, Jeff Wehner, VP Renewable Operations, Duke Energy, said.
Portugal’s Iberwind has increased the availability of its wind farms by around 4% since 2007 and expects further performance improvements following trailblazing tests on yaw alignment and blade aerodynamics, Rui Maia, Iberwind’s Operation and Maintenance Manager, said.
