PANEL DISCUSSION  

TASK 19: How Are The Current Standardisation Measures Being Implemented And How Does The Future Look Like?

  • The new Advanced Technology for Cold Climate report: purpose and study highlights 
  • What are the further needs for technology research and innovation?
  • Who are the standards targeting - developers, investors or manufactures?
  • How will the industry react to the standards coming up?
  • What will be the impact on the financial side of things?
  • What additional areas of wind energy in cold climates need attention? 

Participants include:

René Cattin, Head Of Meteorology, Meteotest

Matthew Wadham-Gagnon, Project Lead, Technocentre éolien

Moderator Ville Lehtomäki,  Senior Scientist,  VTT

10:00

An Investor’s Perspective: Risk Perception And Mitigation On Wind Farms Affected By Cold Climate And Icing Issues 

  • Practical actions and strategies to minimise investment risks
  • What is the role played by standardisation and what additional steps are needed for a risk-managed project?
  • Is upcoming technology a limit or an advantage?
  • Looking into the economics of ice protection systems (IPS): do they make financial sense? Or they only represent an additional cost?
  • Assessment of reduced production prior to deployment: lowering financial risks and uncertainties

RESOURCE ASSESSMENT AND UNCERTAINTY MITIGATION IN COLD CLIMATES 

11:00

What Is The ideal Ice Sensor For Pre-Construction?

  • The importance of avoiding ice growth on sensors and/or meteorological met masts to avoid measurement errors and data loss
  • Using LIDARs as an ice detector
  • Benefits and limits of heated anemometers on:
    • Icing analysis
    • Measurements
    • Pre-construction assessment
  • Are icing duration and severity the only two criteria that make up an ideal sensor? 

Timo Karlsson, Research Scientist, VTT

11:30

Analysing How Ice Impacts The Measured Wind Speed And Uncertainty Analysis

  • Avoiding measurement errors due to icing on sensors in order to gain an accurate energy yield estimate
  • Increasing data availability to lower uncertainties and implement long term correction
  • Converting measurements into predicted effect on power production
  • Keeping in mind access and mast collapse as additional factors for ice impact on uncertainty analysis

Mark Zagar, Meteorologist, Vestas 

12:00

Estimation Of Icing Losses By Using Site Short Term LIDAR Data

  • Methodology and set up of Lidar measurement devices for icing measurements
  • Analysis of LIDAR data for short term meteorological icing
  • Verification with onsite met mast data and reanalysis data
  • Comparison of site measured icing data with icing maps

Oskari Koljonen, Renewable Energy Consultant, SgurrEnergy

Networking Lunch

HIGH FREQUENCY TALKS 

Getting Accurate Data Out Of Your Wind Farm

The aim of these high frequency talks is to facilitate a discussion on how accurate data can not only help mitigate risks in pre-construction but also have a beneficial impact on operation and maintenance activities being performed on sites affected by cold climate and icing issues and, ultimately, use data to bring down costs and enhance AEP.

Each delegate will be given the chance to express their thoughts, concerns, ideas and solutions anonymously and in written form (5 minutes) through an online platform called Sli.do. The moderator will then read out  the audience’s suggestions on how the industry can progress on these issues. The debate will then be opened up to the rest of the room, making this the perfect occasion to take a real step forward on the use of data.

Please come prepared with lots of thought provocative and insightful questions and comments! 

Moderator:  Ville Lehtomäki,  Senior Scientist,  VTT

14:15

Case Study: Real Live Experience With Weather Model Based Icing Maps

  • Evaluating the energy yield potential of a site
  • Validation of the icing maps and distribution of icing conditions
  • Using weather forecast and icing maps to assess:
    • Icing intensity
    • Duration: applying threshold values
    • Impact on the planning phase
  • Identifying production loss due to icing events rather than just statistics on the number of events or the amount of ice
  • How to tackle current technological and climatological challenges
14:45

Hands-On Experience On Ice Prevention System To Lower Uncertainties

During this session Wicetec will share direct experiences from measurement data collected over the last winter as well as results from their very first retrofit project.

Petteri Antikainen, CEO, Wicetec

Pre-Dinner 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!
