Our use of numerical weather prediction (NWP) and other models is highly specialized, and Vaisala has unequalled expertise in applying these techniques to the problem of optimally locating, assessing, and forecasting wind, solar, and hydro resources—at any scale. We have developed many proprietary methodologies that further enhance the effectiveness of NWP and other models for these applications. We also add substantial value by transforming the vast amounts of data output by these models into relevant, actionable information that drives decisions about renewable energy policy, investment, and integration.
Recent projects include:
Offshore Resource Assessment Study
Offshore wind resource map over the Aegean Sea
Vaisala's proprietary wind modeling technologies can be applied for offshore wind resource assessment. Vaisala has created high-resolution meteorological wind resource datasets for many offshore wind projects allowing stakeholders to understand the spatial and long-term temporal variability of their offshore wind resource. Vaisala's experience in offshore assessment includes generating wind maps of offshore areas, long-term temporal analysis of the offshore resource, and project-specific power generation studies.
NWP model simulations are specifically optimized for offshore areas. Vaisala incorporates publicly available point meteorological data (buoy data, offshore platform data, etc.) to validate and correct the modeled wind resource dataset. Vaisala also incorporates satellite-derived observational wind speed data to correct for model bias at locations far offshore. Incorporating observational data sources allows Vaisala to correct for potential deficiencies in the raw model dataset and also to produce validation statistics. This additional processing results in a validated, high-quality offshore wind resource dataset that can be used with confidence.
Climate Change Analysis
Vaisala Advanced Applications has extensive expertise in modeling and performing state-of-the-art climate change assessments. Our experience allows us to help clients analyze a variety of climate change-related concerns. Previous work includes a 2008 Vaisala 3TIER-Services analysis of the effects of climate change on near surface wind speed.
Climate Change Analysis for Wind
Conducted on a global scale, the results of the study were published in the July 2008 issue of North American Windpower. This article provides an overview of the expected changes in wind speed values as simulated by several climate models. In addition to large, region-wide analysis, Vaisala Advanced Applications can also perform climate change assessments for specific projects.
We have also analyzed the effects of climate change on hydropower generation. Using hydrologic and reservoir system simulation models, we analyzed the impact of climate change on a variety of future power system variables including storage levels, firm yield, and energy and capacity values. This methodology can be applied to watersheds worldwide.
