Market Suitability and Performance Tradeoffs Offered by Commercial Wind Turbines across Differing Wind Regimes

Abstract:The suitability of turbine configurations to different wind resources has been traditionally restricted to considering turbines operating as standalone entities. In this paper, a framework is thus developed to investigate turbine suitability in terms of the minimum cost of energy offered when operating as a group of optimally-micro-sited turbines. The four major steps include: (i) characterizing the geographical variation of wind regimes in the onshore U.S. market; (ii) determining the best performing turbines for different wind regimes through wind farm layout optimization; (iii) developing a metric to quantify the expected market suitability of available turbine configurations; and (iv) exploring the best tradeoffs between the cost and capacity factor yielded by these turbines. One hundred thirty one types of commercial turbines offered by major global manufacturers in 2012 are considered for selection. It is found that, in general, higher rated power turbines with medium tower heights are the most favored. Interestingly, further analysis showed that "rotor diameter/hub height" ratios greater than 1.1 are the least attractive for any of the wind classes. It is also observed that although the "cost-capacity factor" tradeoff curve expectedly shifted towards higher capacity factors with increasing wind class, the trend of the tradeoff curve remained practically similar.

“…This method provided valuable insight to evaluate innovative concepts for reducing the cost of energy for land-based wind projects (Malcolm & Hansen, 2006) (Griffin, 2001) (Shafer, et al, 2001) (Smith, 2001). Accordingly, LCOE will be the primary metric used to compare various IO&M strategies in this study.…”

Executive SummaryThis report is intended to provide offshore wind industry stakeholders a basis for evaluating potential cost saving installation, operation, and maintenance (IO&M) strategies and technologies. Some of the IO&M strategies in this report were analyzed without projecting the capital expenditures associated with an enabling technology or method. Thus, the results show the upside or added value to a strategy (e.g. increased energy production), and not the potential downside (e.g. added capital cost of new hardware). The results of the analysis can therefore be used by industry stakeholders to take the cost savings presented in this report and add their revised technologies costs to arrive at a net decrease or increase in cost of energy resulting from a proposed IO&M strategy. This allows many technologies that target the same improvement area to be evaluated subsequent to this study. To clarify this concept, an example is presented below.Company X is interested in bringing an innovative vessel capable of operating at higher wind and wave conditions to market. If a strategy using an innovative vessel capable of operating in higher wind and wave conditions (similar to Company X's design) is shown to reduce costs by $100/kW with respect to the baseline, Company X can see that in order to be viable in the market, they must be able to deliver their innovative vessel at a rate no more than $100/kW greater than the vessel rate used in the baseline. If Company X can deliver their innovative vessel at $25/kW more than the baseline, they will have demonstrated that their new vessel technology is capable of saving $75/kW with respect to the baseline. IntroductionIO&M is expected to account for nearly one-third of offshore wind levelized cost of energy (LCOE) in the United States (U.S. Department of Energy, 2011). Consequently, there is a large potential for reducing LCOE through advanced IO&M strategies. NREL and ECN, along with a panel of subject matter experts who provided input, have used their offshore wind cost modeling capabilities to fulfill the project's two primary objectives:• Conduct analysis and modeling to identify the most practical means of reducing offshore wind LCOE through advanced IO&M techniques, integrated service providers, and preferred supporting infrastructure.• Identify preferred IO&M strategies in a case study of a hypothetical U.S. offshore wind project. viThis report is available at no cost from the National Renewable Energy Laboratory (NREL) at www.nrel.gov/publications.To accomplish the objectives related to installation costs, NREL has developed a new offshore wind turbine installation cost module which, coupled with the NREL offshore wind plant balance of station (BOS) model, is capable of analyzing many scenarios including the six (6) turbine assembly strategies and three (3) additional project installation strategies that this study analyzes.To accomplish the objectives related to O&M costs, ECN has established an O&M tool for the U.S. offshore market based on their industry-l...
