This white paper offers an updated approach to evaluating technological risks associated with the continuing growth of wind energy in terms of increased capacity and lower cost of energy, driven by larger turbine size and technical innovations. Accounting for recent turbine design developments, this white paper updates DNV’s previous work regarding the “Proven” status of wind turbine technology, now proposing a global framework using four different statuses: Proven, Established, Qualified, and Not-Yet-Qualified technology. While some of the criteria need to be fulfilled on a “per region” basis, this updated framework is applicable in all markets globally. Turbine technology risks are reviewed and associated mitigants are proposed. DNV offers these clarifications and refinements to the turbine status framework to allow for a fair and efficient evaluation between different wind turbine models to support the continued successful development of the wind industry globally.
