Global standards development June 2014 NREL is a national laboratory of the U.S. Department of Energy, Office of Energy Efficiency and Renewable Energy, operated by the Alliance for Sustainable Energy, LLC.
Standard A standard is a document, established by consensus and approved by a recognized body, that provides, for common and repeated use, rules, guidelines or characteristics for activities or their results, aimed at the achievement of the optimum degree of order in a given context. 2
Consensus consensus: General agreement, characterized by the absence of sustained opposition to substantial issues by any important part of the concerned interests and by a process that involves seeking to take into account the views of all parties concerned and to reconcile any conflicting arguments. NOTE Consensus need not imply unanimity. 3
Roles and responsibilities Stakeholders Develop standards Regulators Identify which standards apply Certifying bodies Assess compliance with the requirements of the standards Note: if regulators do not set requirements the market may do so themselves. 4
Benefits of standards Clarity\order Removal of market barriers Reduce risk (and thus LCOE) through: o appropriate level of safety o high quality reproducible test results 5

US activities AWEA is recognized by the American National Standards Institute (ANSI) as an Accredited Standards Developer AWEA Standards Development Board (SDB): 1. AWEA SDB actively participates in the development of all Wind Energy related Standards. 2. Promote the use of existing consensus standards by the US Wind Industry and authorities having jurisdiction 3. Identify industry needs for National US standards 4. Develop ANSI standards to fill gaps where neither international or national standards currently fill. 5. Develop publications to identify US National deviations where there are gaps in existing standards 6. Prioritize in developing standards harmonized at the highest possible level Adopt the current IEC standards as US standards through ANSI. 15
Applicable lessons learned Get all stakeholders involved Find consensus on the right level of structural safety we can accept as an industry Collaboration/cooperation Harmonize at the high level (ideally global) use domestic standards where needed Marketing/education Think of structure Identify R&D needs to fill gaps in knowledge 16
