Desktop site screening
We have developed tools to support fast and effective screening for greenfield wind project sites. Typically, the process considers the following factors:
- Wind resource. Our high-resolution wind resource maps, among other data sources, permit efficient identification of promising windy sites and realistic estimates of production potential
- Buildable windy area. The size of your project is constrained by the buildable area, which may be influenced by topography, property setbacks, and other considerations. We can estimate the buildable area and create preliminary layouts to illustrate your options.
- Transmission lines. Proximity to transmission and the load-carrying capacity of existing lines are vital considerations for most projects. Our GIS experts and power engineers can help you assess your interconnection options.
- Land cover, site access, and land-use constraints. We apply objective screening criteria to find and rank developable sites, including, e.g., compatible land uses, road access, and parks and other exclusions.
Our software can screen large regions for attractive sites and produce a ranked list with characteristics such as estimated capacity factor and rated capacity. Or if you prefer, you can perform your own screening using Windnavigator.
When it comes to selecting a site, there is no substitute for site visits. Our field engineers can work with your team to ground-truth the assumptions and data used in the initial site screening (such as the presence and location of existing roads and transmission lines), and address issues such as:
- Road and transmission access
- Potential visual and noise concerns
- Issues of cultural, environmental, historical, or other community sensitivity
- Possible wind monitoring locations, including site coordinates, access, and surroundings
- Cellular telephone service reliability for automated data downloading
A feasibility study allows you to weigh all of the potential risks and rewards in developing a project. A typical study will include some or all of the following elements:
- Resource assessment based on available resource maps and data
- Preliminary layout, turbine selection, and energy production estimate
- Technical feasibility and technology options
- Potential environmental concerns such as visual and noise impact and threats to endangered species
- Regulatory requirements and challenges
- Interconnection options
- Potential challenges for community acceptance
- Cost and revenue projections and financial pro forma
