The SAM web site will be upgrading Monday, May 23 from 4:00-5:00pm (Denver/mountain time). 

After doing a major change to our infrastructure, we have found a minor issue that we have corrected but will need to reboot the web site for it to take affect.

To make it as convenient as possible, we have scheduled it for Monday, May 23rd at 4:00pm (mountain). The process takes 15-20 minutes, but the site will only be unavailable for a short time. However, your session information will be lost (eg if you're writing a post, what you have written could be lost). 


The Wind category is for articles about SAM's Wind Power model and determines what articles appear on the Wind Power page.

SAM's Wind Power model can model a single wind turbine or a wind farm with more than one turbine.

Combine the Wind Power performance model with the Residential or Commercial financial model for a behind-the-meter project that uses wind power to reduce a building or facility's electricity bill, such as a residential wind turbine, or wind turbines on a farm or ranch for self-generation. Or, combine it with one of the PPA financial models for a project that sells power at a power price negotiated through a power purchase agreement, such as a large-scale wind farm.

Land-Based Balance of System Costs

SAM includes an implementation of NREL's LandBOSSE Python model to calculate balance-of-system costs for land-based wind projects.
