Product Code: SCA-14

The global wind power industry continues to transform and mature. As cost reductions and efficiencies of scale continue to be made, wind power is better able to compete in markets where policy support for clean energy generation has been limited. Due to innovation in technologies, supply chain strategies, and turbine designs, wind turbine vendors are meeting future challenges and preparing to compete purely on cost against traditional generation.

The supply chain plays an outsized role in this process through improvements and innovations in components and manufacturing processes. During the past 2 years, more flexible supply chain sourcing strategies have resulted in cost reductions, enabling greater geographic market access while reducing risk and ensuring profitability for wind turbine vendors and their partners. Continuing overcapacity in most areas (but not all) of the supply chain is providing more choice, flexibility, and cost control. This is allowing wind turbine OEMs to more easily adjust what components they produce in-house, what is outsourced, and when a blend of both is advantageous for cost, technological, or geographic reasons.

This Navigant Research report assesses the significant issues pertinent to the global wind power industry's supply chain. The study examines 11 component categories and identifies more than 300 component suppliers; it also scrutinizes more than 200 suppliers across four groups of materials. Analysis is provided of the top wind turbine vendors and their manufacturing capabilities, supply chain relationships, and technology strategies. Key offerings and the capacity for leading suppliers, located primarily in North America, Europe, Asia Pacific, and Latin America, are quantified. The report also analyzes the major technology trends within each of the component and materials categories, as well as the related manufacturing capacity and supply versus demand dynamics expected through 2018.

Key Questions Addressed:

  • What improvements are being made to the main components used in a wind turbine?
  • How do the manufacturing capacities of the key components affect supply versus demand dynamics?
  • Which component and materials suppliers are most active in the wind power market and what are their offerings?
  • Who are the top wind turbine vendors and what are their manufacturing capabilities and supply chain strategies?
  • How are strategic decisions around sourcing materials like fiberglass, carbon fiber, and others shifting?
  • What components are becoming more commoditized and are being produced by lower-cost suppliers?
  • How are regional manufacturing cost issues affecting the wind turbine market?
  • Where is cost cutting occurring in the wind power components and materials supply chain?
