Optimising Wind Farms In Cold Climates

Optimising Wind Farms in Cold Climates

Forum Day 1: Tuesday 17th October 2017



Chair's Opening Remarks 

Ville Lehtomäki, Senior Scientist, VTT



Financial Perspective On What’s Perceived As A Risk And How To Support An Investment

  • How to prove performance of ice prevention and detention systems in terms of quality, reliability and value

  • Gathering enough quality data to support the investment decision process

  • Learning about new investment ventures focused on understanding meteorological icing

  • Hear about estimated icing and consultancies recommendations

  • How are bank and investors treating and experiencing the prediction of ice loss?

Lucia Fuselli, Investment Officer, European Investment Bank 


Contract Considerations For Non-Standard Projects

  • Challenges faced when moving to cold regions and how we can manage them  
  • What additional steps are needed in contract negotiation
  • Technology optimisation and warranty issues from a project finance perspective 
Eustace Furtado, Commercial Leader, GE Renewable Energy 

Operating Wind Farms In The Wintertime In A Port Environment

Winter in Belgium has the typical character of a moderate sea climate.  The temperature changes are tempered by the location next to the North Sea and the presence of the Gulf Stream. This means that summers are rather cool and winters are mild. The night temperature during the winter period from November till March is often around 0°C.

These specific climate conditions, together with the location of the wind parks in the middle of the port activities, have influenced strongly the way in which Vleemo (right bank of the river Scheldt) and Wind aan de Stroom (left bank) operate their wind parks during the winter period.  Both technical and management aspects are covered in the presentation.

Jan Winters, Strategy Manager, Vleemo

Icing Modelling vs. Ice Loss: Overcoming The Difference In Results  

  • Understanding the icing phenomenon through the study of power lines and on structures

  • Trying to describe icing through accurate modelling and calculations

  • Avoiding large uncertainties about losses due to icing

  • Discussing the role played by technology and its impact on losses

  • Longer blades, different modelling challenges?

  • Using experience based on data gathered from turbine types that are now getting older

  • Estimation of ice loss to better predict it and lower uncertainties

  • Long term impact of icing loss and winter variability: how do you validate it?

  • Comparing ice models in order to recommend standardised practices on how to model and simulate ice throw


Perspectives On Cold Climatic Testing For Product Development And Validation

  • Testing of individual components to full systems
    • Small to large/full-scale climatic testing facilities
  • Specialized testing facilities
    • Corrosive environments
    • Static and cyclic temperature control
    • Over-icing
  • Case studies for different climatic testing scenarios
    • Various size scales and environments
    • Supporting product development to design reliable and robust products
Per Baunegaard With Jensen, Test Engineer - Component And Structure Testing, FORCE Technology 

Icing Input For Site Assessment And AEP Calculation  

  • Gathering wind data for yield and loads calculations

  • When there are no data from project developers, how do you estimate ice losses?

  • Best practices on how to provide wind data and developers’ responsibilities

  • Should developers provide ice formation data or should OEMs give their own estimate?

  • How to avoid the risk of quality and accuracy being lost: conservative vs. detailed approach

Neil Davis, Research Assistant, DTU 


Power Curve Verification In Cold Climate

  • Verification based on the new IEC 61400-1-12 standard

  • Comparison of different operating strategy for wind turbines in cold climate and impact on the amount of power loss due to icing

Rene Lemoine, Project Manager - Wind Farm Development, SwissWinds 

Networking Break And Afternoon Refreshments 


Increasing Turbine's Availability From Moderate To Severe Icing Conditions 

  • Allowing efficient continuous turbine operation through ice protection systems 
  • Preventing stoppages due to icing
  • How to achieve low operating costs and high availability
  • Practical case studies from Sweden and Canada

Petteri Antikainen,  CEO,  Wicetec


Consideration Of De-Icing Systems In Energy Yield Assessments

  • Overview of the impact of de-icing systems on the energy yield
  • Balancing heating cost and increased energy yield
  • Contractual mitigation and verification
Oskari Koljonen, Renewable Energy Consultant, Wood Group 


CATCH THE BOX! Standardisation Of Practices And Ice Detection Systems

This session has been designed for audience participation and knowledge sharing with no excuses! Instead of slowly passing around a stick microphone, simply throw the soft Catchbox to the first person in the room who’s meeting your eyes!

Delegates are encouraged to come along with ideas, comments and provocative questions for their peers. This is a self-moderated session so there won’t be such thing as hiding in corners!


Round Table Discussions

  1. Designing the perfect instrument campaign

  2. Bridging the gap between energy prediction and loss calculations

  3. What is expected from OEMs for the next 20 plus years of blade performance?

  4. Building a know-how guide for countries with unexpected icing and high winter variability


Neil Davis, Research Assistant,  DTU

Mark Zagar, Senior Specialist, Energy Meteorology, Vestas


Discussion Highlights

Hear quick snapshots of each of the breakout discussions from the group facilitators.


Speed Networking

Realising the importance of connecting with your peers, we organised a moderated networking session where delegates are prompted to meet others in brief 3-minute rounds. The moderator will be keeping track of time and announcing participants when to switch partners.

Make sure you bring lots of business cards along with you!
