About the Case Region

  • Raahe has declared itself to become the

Wind Power Capital of Finland

  • 20 % of Finland’s wind power capacity
  • Around 20 planned wind farms (10
  • perators)

Research

  • Motivation:

– Turbine manufacturers => Customer needs – Wind power companies => General criteria of the business

  • Method: Semi-structured interviews
  • Target Group: Technical experts and

decision makers of the wind energy companies

  • Sampling: 70% (7 out of 10 operators)
  • Answers classified to themes

Results

10 20 30 40 Reliability Production volume Cost factors Availability factors Organization of maintenance Others Relative importance of themes (%)

slide-8
SLIDE 8

Results

  • Theme Reliability (36%)

– Suppliers reputation as a company

  • Credibility
  • Recognition
  • Background factors
  • Financial situation
  • Practices and services overall

– Suppliers location and warranty issues – Production statistics and track record, suitability to arctic conditions

slide-9
SLIDE 9

Results

  • Theme Production volume (23%)

– Tower heights and blade lenghts – Performance (kWh or MWh price) – (gearless options)

slide-10
SLIDE 10

Results

  • Theme Cost factors (17%)

– The total cost (incl. Infrastructure works)

  • Various limitations of total cost

– Turbine’s price, cost of grid technology integration – (the cost of the operation and maintenance)

slide-11
SLIDE 11

Results

  • Theme Availability factors (13%)

– Availability of desired type of turbine – Availability of spare parts – Power plant delivery time

slide-12
SLIDE 12

Results

  • Theme Maintenance (8 %)

– The speed of the maintenance when needed

  • Theme Others (4 %)

– R&D cooperation between the firms – Noise and safety (!)

  • Only one interviewee mentioned
  • Blade heating

Conclusions

  • Reliability of supplier is more important

than the reliability of product

  • Total cost of a wind farm is more

important than the cost of the single turbine

  • The sourcing of wind turbine is in line with

the ”general” sourcing criteria:

  • Quality (and reliability) is more important than

price
