STATEMENT OF WORK

"Distributed Wind Turbine Competitiveness Improvement Project –

Component Improvements and Overall System Optimization”

December 2, 2014

1.0 BACKGROUND

The U.S. Department of Energy (DOE) Office of Energy Efficiency and Renewable Energy (EERE) Wind Program defines distributed wind (DW) in terms of technology application based on a wind project’s location relative to end-use and power-distribution infrastructure, rather than on technology size or project size; thus, the distributed wind market includes turbines and projects of many sizes. Wind systems are characterized as distributed based on the following criteria:

• Proximity to end-use: wind turbines installed at or near the point of end-use for the purposes of meeting onsite load or supporting the operation of the local (distribution or micro) grid.

• Point of interconnection: wind turbines connected on the customer side of the meter or directly to the local grid1.

At the smaller end of the DW spectrum, the small wind2 industry in the United States (U.S.) has historically been a leader in the international market. Progress has been made in improving consumer confidence in the products through the creation of the Small Wind Certification Council (SWCC) that is responsible for certifying small wind turbines to the requirements of the American Wind Energy Association’s (AWEA) Small Wind Turbine Performance and Safety Standard3. Other organizations certify small wind turbines to this standard. Seven (7) small wind turbines have been certified by the SWCC, with one additional turbine being granted a limited power performance certification. In addition, one turbine categorized as a medium turbine has received power and acoustic certification. Among those certified to date, several are products that are manufactured in the United States. Few turbines in the range of 200m2 to 1000m2 rotor swept area (RSA) are pursuing certification to the International Electro-technical Commission (IEC) 61400-1 or DNV GL (Det Norske Veritas Germanischer Lloyd) standards.

Over the last several years, the National Renewable Energy Laboratory (NREL) helped establish four (4) Regional Test Centers (RTCs), with one each in Kansas, New York, Texas, and Utah. These, and any other qualified testing body, support the U.S. industry’s need to expand the distributed wind turbine testing and certification infrastructure and ensure that wind turbines sold in the U.S. market are viable, commercial products. Although these testing facilities increase the number of distributed wind turbines that can undergo certification testing, fewer wind turbines than previously expected are ready for certification.

1 U.S. Department of Energy, Energy Efficiency & Renewable Energy, Wind Program. 2013. Distributed Wind. Available at wind.energy.gov/wind_dist_tech.html (last update May 2, 2013) 2 The US DOE defines small wind as 100kW or less. Applicable standards for turbine certification will be dependent on the rotor swept area (RSA) of the turbine. IEC 61400-02 applies to turbines <200m2 RSA. The AWEA Standard size limitation is consistent with IEC 61400-2 limitation. Turbines greater than 200m2 RSA must comply with IEC 61400-1, -12, -23, and any other applicable standards.

The National Renewable Energy Laboratory (NREL) is positioned to support U.S. small and midsize wind turbine manufacturers that demonstrate a strong commitment to improving their ability to compete in the global distributed wind market space. Wind technology expertise available at NREL’s National Wind Technology Center (NWTC) has been instrumental in the past in supporting technology improvements.

Through NREL, the DOE EERE Program sponsors a multifaceted wind energy research portfolio to assist the U.S. wind industry develop competitive, high-performance technology for global energy markets.

One specific program objective is to increase the number of certified small and midsize wind systems and reduce the levelized cost of energy (LCOE) of turbines used in distributed electricity systems to be competitive with retail electricity rates. “The Distributed Wind Turbine Competitiveness Improvement Project (CIP) - Component Improvements and Overall System Optimization” is intended to target this program objective and increase the competitiveness of U.S. small and midsize wind turbine manufacturers.

2.0 OBJECTIVE

The objective of the CIP is to expand U.S. leadership in the domestic and international wind turbine market sector by assisting U.S. manufacturers4 in lowering the LCOE of wind turbines through component improvements. The expected outcome is an increase in the number of certified distributed wind turbines available for the U.S. market. Although DW is not defined by size, for this solicitation the turbine size will be capped at 1000m2 RSA.

3.0 SCOPE OF WORK

Under the CIP, Subcontractor(s) shall be selected to conduct work on Component Improvements and Overall System Optimization.

This scope of work emphasizes a disciplined engineering development process, tests to verify component, process, or system designs, and documentation necessary for certification and product commercialization.

The Subcontractor shall select a baseline wind turbine that shall be the focus of this project. The Subcontractor shall conduct work that supports designing, building, and or testing improved components.

The project results are expected to increase the number of U.S. – manufactured certified wind turbines and reduce the LCOE of these turbines installed in distributed applications.

4.0 TASKS

The Subcontractor shall perform the work, conduct the meetings, and deliver the work products described herein, as minimum requirements. The Subcontractor shall comply with the technical requirements described herein. In addition, the Subcontractor shall complete and submit to NREL the applicable “Figure of Merit – Cost of Energy” (either Attachment 4 or 5, dependent on turbine size of either <200m2 or 200 m2 – 1000m2).

It is anticipated that the Subcontractor shall pursue low risk, medium to high impact, incremental component improvements, rather than experimental, unproven or high risk innovations that significantly alter the turbine configuration. Proposed efforts should focus on high impact components, such as foundations, towers, alternators, rotor components and controls. The Subcontractor shall select specific component(s) of the baseline wind turbine system (e.g., rotor, alternator/generators, nacelle, control and electrical systems, tower, and structure support, including foundation). The improved component development process, in general, involves the design, fabrication, and testing of component(s) or subsystem that is expected to improve the turbine performance, reliability or cost. This could be accomplished through a number of design changes of components or control software.

4 Attachment 3, Eligibility Verification, must be completed and submitted as part of the proposal.

The Subcontractor shall show that the expected component improvement results in an improved wind energy system performance and must provide the technical rationale for each proposed improvement, carefully assessing the associated risks and benefits. LCOE shall be the primary figure of merit used to compare and track improvements. The baseline costs, and proposed costs resulting from the proposed improvement, shall be provided in the proposal (see Attachments 4 and 5). A summary of the actual costs shall then be provided as a task deliverable. Therefore, improvements should focus on lowered capital costs, increased performance, improved reliability, and reduced replacement, operation and maintenance costs. The objective within this effort is to show the advantages of a new/re-designed component(s) in support of enhanced capabilities, performance, reliability, and/or reduction in overall costs. Elements of improvements and the need for a rigorous study for the development and manufacture of the component(s) must be identified.

Task 4.1: Status-quo Analysis, Opportunity Identification, New Specifications:

The Subcontractor shall provide a brief analysis of the opportunity the work effort under this topic will address, starting from the current situation in terms of product configuration and performance, as well as engineering data accumulated to date. This includes drawings, reports, testing data, analysis data and spreadsheets, photographs, etc., that can help identify the requirements of the component(s) of interest.

The Subcontractor shall also provide a letter report listing the specifications and requirements of the improved component(s).

The letter report shall also include a discussion of the advantages of the component(s) improvements in terms of manufacturing, reliability, safety, performance and cost together with expected results (e.g., comparisons of load or stress, deflection values, dynamic response and modal characteristics, fatigue life, installation costs, manufacturing costs, etc.).

Task 4.2: Detailed Product Development Plan Based on the Product Development Plan, the Subcontractor shall identify all the necessary steps for the engineering of the improved component(s), from conceptual to detailed design, including the methods and tools that are planned for the work. The Subcontractor shall identify the standards being followed and outline the procedures for qualifying the design to meet applicable certification standards.

All of the above items shall be summarized in a Detailed Product Development Plan document and submitted to NREL for review. A Product Development Plan shall include, but not limited to, the following items:

• Product requirements

• Engineering effort

• Prototype development

• Testing effort

• Tooling development

• Manufacturing plan

• Certification plan

Task 4.3: Implementation and Analysis The Subcontractor shall execute and complete all the work described in the product development plan.

Upon completion of this effort, the Subcontractor shall deliver a complete structural analysis report of the component(s) under investigation, including any test reports, detailed drawings, solid models, and results of models and finite element analyses. If a software or electro-technical component is the focus of the analysis and design, then a detailed analysis report shall be submitted in lieu of the structural analysis (e.g., control system design) report.

If applicable, fatigue damage estimates and associated expected lifetimes of the components shall be reported comparing the new and old configuration data. The standards and codes used in the analyses shall be stated in the report, with particular emphasis on the methodology and assumed load and material safety factors.

Task 4.4: Revised Cost of Energy At the completion of the component improvement work effort, the Subcontractor shall develop a revised LCOE, comparing the baseline, proposed and actual cost elements. The Subcontractor shall summarize the final system costs and describe, in detail, how and why it is consistent or different from the estimates included in the original proposal.

5.0 REVIEW MEETINGS AND TRAVEL REQUIREMENTS

The Subcontractor may, but is not required to, travel to NREL one or more times to discuss the review of tasks or other technical support from NREL.
