Low Wind Speed Technologies Annual Turbine Technology Update (ATTU) Process for Land-Based, Utility-Class Technologies

The Low Wind Speed Technologies (LWST) Project comprises a diverse, balanced portfolio of industry-government partnerships structured to achieve ambitious cost of energy reductions. The LWST Project goal is: 'By 2012, reduce the cost of energy (COE) for large wind systems in Class 4 winds (average wind speed of 5.8 m/s at 10 m height) to 3 cents/kWh (in levelized 2002 dollars) for onshore systems.' The Annual Turbine Technology Update (ATTU) has been developed to quantify performance-based progress toward these goals, in response to OMB reporting requirements and to meet internal DOE program needs for advisory data.
