Falling costs in Europe are prompting US. offshore wind developers to raise growth outlooks but faster deployment will require accelerated supply chain and infrastructure support, company executives said at the U.S. Offshore Wind 2017 conference on May 8.
New data has revealed the impact of leading-edge erosion on energy production and advanced protection packages now offer long term performance gains and optimized maintenance windows, industry experts said.
The Blauwind II consortium bid a record Dutch price of 54.5 euros/MWh ($58.0/MWh) to win the Borssele 3&4 offshore wind tender, demonstrating how installation learnings and wider construction roles are allowing project stakeholders to establish a lower plateau of prices, industry experts told Wind Energy Update.
Original Equipment Manufacturers are fending off competition in wind power operations and maintenance through a combination of longer service agreements, tailored offerings and takeovers of independent service providers, experts told Wind Energy Update.
Europe's wind operators are turning to market-responsive contracts and data analytics to maximize wholesale market gains and cut costs as feed in tariffs give way to competitive project tenders, experts told Wind Energy Update.
A data-led performance optimization plan can boost average wind generation by between 3% and 8% and some sites can achieve further gains through forestry restructuring, Aaron Culver, Measurement & Analysis Team Leader at renewable energy consultancy SgurrEnergy, 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.
