About Us

Persimia, LLC is a small business founded in 2017 headquartered in Atlanta, Georgia. Our mission is to facilitate wind turbine siting, permitting, and environmental impact analysis through the use of physics-based modeling and simulation. Our company was founded by two highly experienced and internationally recognized Georgia Tech professors with extensive expertise in aerodynamic modeling, multi-physics simulation, and probabilistic analysis. Using state-of-the-art simulation tools, we provide high-value environmental impact assessment for wind farm developers, permitting authorities, and surrounding communities.

Here at Persimia, we are true believers in the value of wind energy. We are also dedicated to ensuring community safety and acceptance near wind installations. The Persimia project began in 2009, when our founders were asked to develop setback standards for a particular wind farm, focusing only on the risk of blade and ice throw. Through detailed aerodynamic modeling of blade and ice fragments in free flight, the world’s first physics-based guidelines for wind turbine setback standards were created (more information is available here). However, because each potential wind installation site has a unique topography and surrounding environment, we recognize the need for site-specific risk analysis. Persimia allows users to exercise our state-of-the-art simulation tools to gather high-resolution environmental impact data for a specific wind turbine site. Our simulation models allow users to determine noise levels, turbine visibility, probability of blade or ice throw impact, and the presence of shadow flicker in areas of new turbine installations. These results provide stakeholders with unbiased, physics-based environmental impact assessments on which siting and permitting decisions can be based. Our risk analysis package is an essential tool for any new wind installation development project.
