The objective of the proposed IEA Wind Task 40 on Downwind Turbine Technology is to coordinate international research and investigate the benefits of downwind turbine technology toward the reduction of levelized cost of energy (LCOE) and proliferation of offshore and onshore wind plants. Other objectives include:
- Innovate wind turbine technology
- Identify and resolve technical issues relevant to downwind turbine design
- Modify IEC standards as needed – for example, IEC61400-1
- Reshape the national regulations – for example, identify constraining regulations and propose changes to acceptance criteria.
Task 40 investigates the benefits of downwind turbine technology toward the reduction of levelized cost of energy (LCOE) and proliferation of onshore and offshore wind plants.
The Task is designed to capitalize on past and recent experiences as well as recently developed computational capabilities. The focus will include offshore and onshore wind turbine while investigating the relevant design conditions where downwind turbines might offer advantages.
The task will include an objective, harmonized approach to assessing the LCOE of downwind turbines based on select baseline turbine models and methods accepted by the participants.
