Vestas was the first to receive a turbine certification under a new system administered by the International Electrotechnical Committee conformity assessment system for Renewable Energy (IECRE).

The new certification system creates a clearer, more harmonised, and less costly process to certify wind turbines and other renewable energy equipment. Harmonising certificates across multiple markets will reduce the costly and time-consuming need to repeat tests as well as create greater clarity for end-users on what exactly is being certified.  Industry stakeholders including equipment manufacturers, power producers, insurance companies, test laboratories and certifying bodies have led the effort to create the first stakeholder-driven set of certification rules. The IECRE certificates have now been approved for use in many of the world's largest wind power markets, including China, Germany, the USA, and elsewhere. The first wind turbine certificate under the new system was issued on 27 October 2016 by certification body DNV GL, for the Vestas 2MW platform's V100-2.0MW mark 10 version.
