Larger, higher efficiency turbines and the “clustering” of project resources are driving down offshore wind maintenance costs as they become increasingly important in project valuations, Tom Harries, Wind Energy Analyst at Bloomberg New Energy Finance (BNEF), said.
TransAlta, Canada's largest wind operator, estimates condition monitoring systems (CMS) have increased its Annual Energy Production (AEP) by 2.5% and the company is piloting a down-tower repair study which could further improve the business case for CMS, Tracy Duncan, Lead Reliability Engineer at TransAlta, said at the Wind O&M Canada 2016 conference.
Average lifetime revenue for Vattenfall’s Kriegers Flak project in Denmark is forecast to be 20% lower than the record-low bid price and reflects falling CAPEX and cost of equity in the growing offshore wind market, Tom Harries, Wind Energy Analyst at BNEF, told the Offshore Wind Europe conference on November 22.
Expiring tariffs are set to boost repowering demand but new auction rules will require developers to optimize full-life costs and navigate power network priorities to maximize gains, industry sources told Wind Energy Update.
Predicted sharp growth in U.S. offshore capacity will require innovative insurance products based on early insights into technology choices and lessons learned on onshore operational risk, insurance industry experts told Wind Energy Update.
To compete on costs with fixed-bottom offshore wind and other renewables, the floating wind industry should industrialize the foundation in the same way it has manufactured and commoditized the turbines for onshore wind, according to Henrik Stiesdal, wind energy pioneer and former CTO of Siemens Windpower.
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.
The demand for cable lay vessels will “pick up considerably” in the German, U.K. and Dutch offshore wind markets and remain sustained by at least decade’s end, Andy Readyhough, senior business development manager at DeepOcean, 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.
