Evaluation of Optimal Distribution of Wind Power Facilities in Iowa for 2015

Description: By the end of June 1999, about 250 megawatts of wind generation will have been dedicated in the state of Iowa. This represents the beginning of what is likely to be significant wind capacity development during the next 20 years in the state, as a result of possible public and governmental mandates and consumers' desire for sustainable sources of energy. As the utility industry in the United States moves towards a new structure, renewable energy sources continue to be an important part of new resource development. In this paper, we consider the predicted trends in load growth in Iowa. After accounting for the retirement of nuclear and older fossil fuel facilities over the next 15 years, we estimate Iowa's potential renewable generating capacity through the year 2015 and anticipate the contribution of wind energy to Iowa's portfolio. The Iowa Wind Energy Institute (IWEI) has been monitoring the wind resource in Iowa since June 1994 to obtain wind speed averages at 10, 33 and 50 meters above ground at fourteen geographically dispersed potential wind farm sites. Winds in the Midwest are primarily generated by fronts moving through the region. The Northwest Buffalo Ridge area of Iowa typically has wind speed averages of 7-8 m/s. Central Iowa may have typical winds slightly below this mean value. However, as a front passes through the state, there will be times when a wind farm in Central Iowa will produce more energy than one on Buffalo Ridge.

Revealing the Impact of Climate Variability on the Wind Resource Using Data Mining Techniques (Poster)

Description: A data mining technique called 'k-means clustering' can be used to group winds at the NWTC into 4 major clusters. The frequency of some winds in the clusters is correlated with regional pressure gradients and climate indices. The technique could also be applied to wind resource assessment and selecting scenarios for flow modeling.

Measuring wind plant capacity value

Description: Electric utility planners and wind energy researchers pose a common question: What is the capacity value of a wind plant? Tentative answers, which can be phrased in a variety of ways, are based on widely varying definitions and methods of calculation. From the utility`s point of view, a resource that has no capacity value also has a reduced economic value. Utility planners must be able to quantify the capacity value of a wind plant so that investment in conventional generating capacity can be potentially offset by the capacity value of the wind plant. Utility operations personnel must schedule its conventional resources to ensure adequate generation to meet load. Given a choice between two resources, one that can be counted on and the other that can`t, the utility will avoid the risky resource. This choice will be reflected in the price that the utility will pay for the capacity: higher capacity credits result in higher payments. This issue is therefore also important to the other side of the power purchase transaction -- the wind plant developer. Both the utility and the developer must accurately assess the capacity value of wind. This article summarizes and evaluates some common methods of evaluating capacity credit. During the new era of utility deregulation in the United States, it is clear that many changes will occur in both utility planning and operations. However, it is my judgement that the evaluation of capacity credit for wind plants will continue to play an important part in renewable energy development in the future.

International Clean Energy Analysis Gateway: Assisting Developing Countries with Clean Energy Deployment (Fact Sheet)

Description: The International Clean Energy Analysis Gateway seeks to enhance developing country access to energy efficiency and renewable energy analysis tools, databases, methods, and other technical resources in a dynamic user interaction environment. In addition to providing information on available tools, the gateway also is a platform for Web seminars, online training, peer networks, and expert assistance. The gateway is sponsored by the U.S. Department of Energy (DOE) and the United Nations Industrial Development Organization (UNIDO) and managed by the National Renewable Energy Laboratory (NREL). Further cooperation is desired with organizations that can help expand the information presented in the portal and assist with outreach and training.

GIS Method for Developing Wind Supply Curves

Description: This report describes work conducted by the National Renewable Energy Laboratory (NREL) as part of the Wind Technology Partnership (WTP) sponsored by the U.S. Environmental Protection Agency (EPA). This project has developed methods that the National Development and Reform Commission (NDRC) intends to use in the planning and development of China's 30 GW of planned capacity. Because of China's influence within the community of developing countries, the methods and the approaches here may help foster wind development in other countries.
