Whether designing hybrid microgrids or distributed generation systems, our software solutions:
Combine engineering and economics in one powerful model
Allow users to quickly and efficiently determine least-cost options
Simulate real-world performance and deliver a choice of optimized design
Consider geographic-specific criteria and risks, such as fuel price changes, load growth, accelerated battery degradation and changing weather patterns.
The HOMER Pro® Microgrid software by HOMER Energy is the global standard for optimizing microgrid design in all sectors, from village power and island utilities to grid-connected campuses and military bases. Originally developed at the National Renewable Energy Laboratory, and enhanced and distributed by HOMER Energy, HOMER (Hybrid Optimization Model for Multiple Energy Resources) nests three powerful tools in one software product, so that engineering and economics work side by side.
Module packs are designed to help you find the right set of modules for your application quickly. With the exception of the Expert Package, which includes every module.
