Windnavigator – Wind Resource Grids

The Wind Resource Grids (WRG) provided by AWS Truepower through Windnavigator give users the ability to do everything from siting met towers to designing preliminary layouts to obtaining preliminary estimates of the wind energy generated for small to multi-turbine wind projects. These files are not intended for detailed plant design or definitive energy production estimates. View Video

Windnavigator – Time Series Data

Our time series data sets allow you to better understand the wind resource and energy production potential of your site and to conduct measure-correlate-predict (MCP) analyses. Time series come in two types: Historical time series spanning periods from 10 years to over 35 years, depending on the source OR Typical Year Virtual Met Masts (TY-VMM) containing a sample of 365 days scaled to our 200-meter resolution mean wind maps.

All are provided in a universal CSV format that can be imported directly into a spreadsheet, Openwind, Windographer, and other plant design and resource assessment software. View Video

Windnavigator – Data and Maps

Regional, high-resolution resource maps and data for site screening and early-stage feasibility studies. Products include mean wind speeds, speed-frequency distributions, directional distributions, and diurnal and seasonal patterns, as well as capacity factor maps for selected turbine models. GIS and CSV formats. View Video

Using Uncertainty Maps to Optimize Wind Plant Design and Manage Risk

Uncertainty maps can be a useful tool in designing wind resource assessment programs and optimizing plant layouts to reduce project risk. If done correctly, they implement quantitatively what we know intuitively: that uncertainty varies in complicated ways depending on terrain, wind conditions, and the wind flow model used. View video

A Performance Comparison of Four Numerical Wind Flow Modeling Systems

Dr. Michael Brower, CTO of AWS Truepower presents the answers to questions about the actual performance of widely used wind flow models, taken from a recent study. Presented at EWEA, Barcelona 2014.

Coupled numerical weather prediction (NWP) and linear wind flow models have been used for over a decade for micro-siting wind turbines and wind resource mapping. They are designed to capture key atmospheric phenomena at relevant scales while keeping computer time manageable. However, only a few, limited studies have assessed whether these modeling systems perform better than the more widely used, stand-alone models such as Jackson-Hunt (WAsP) and RANS CFD, and under what meteorological and topographic conditions. This research study seeks to answer these questions. View Video

Complex Wind - Tehachapi Pass

Managing Wind Resource Risk at Complex Sites: An Integrated Approach

(Original Broadcast Date: February 20, 2014)
How meteorological expertise, state-of-the-art atmospheric models and advanced measurement methods can increase project value and reduce financial risk.​

All wind project investments depend greatly on the uncertainty or risk in a project's wind resource estimates. This is especially true of large wind projects at complex sites with steep terrain, varying thermal stability, mesoscale circulations and other challenging meteorological aspects. Such conditions are often misrepresented or missed in conventional models and measurement techniques.

In this webinar by AWS Truepower, wind resource experts Dr. Michael Brower, Dr. Philippe Beaucage, and Matthew Filippelli will discuss case studies of actual wind projects in complex terrain and wind regimes, showing how an integrated approach combining meteorological expertise, advanced wind flow models, and remote sensing (sodar and lidar) can increase a project's value and reduce risk.

Understanding the Financial Impact of Uncertainty in Wind Projects

How risk translates to dollars in wind projects.
(Original Broadcast Date: November 7, 2013)

One of the biggest risks in wind development is the uncertainty of the wind resource. In this webinar by AWS Truepower, we will demystify how this resource uncertainty impacts energy production estimation, investment and financing. Presented by AWS Truepower CEO Bruce Bailey, and Director of Investor Services, Josh Kunkel, the following topics will be discussed:

• The steps Involved in predicting wind plant output
• Sources of losses and uncertainty
• Probabilities of energy exceedence and how to interpret them
• The impact of energy uncertainty on capital structure and debt capacity
• Implications of energy values on future cash flows View Video

Solar Monitoring Systems

This short video by AWS Truepower meteorologists provides a thorough introduction to solar site monitoring: A thorough understanding of a project site’s solar resource is an essential element to prospecting, detailed project engineering and financing. Publicly available data sources are often used for preliminary site assessment, but imperfect data and models, complex cloud or solar climates, and other factors can combine to create significant uncertainties. With an increase in project size from tens to hundreds of megawatts, a much more rigorous approach is needed to accurately determine a site’s potential. View Video
