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:

HOMER simulates the operation of a hybrid microgrid for an entire year, in time steps from one minute to one hour.

HOMER Pro is the global standard for optimizing hybrid power system design in all sectors. Originally developed at the National Renewable Energy Laboratory (NREL), it provides insight into the complexities and trade-offs of designing cost effective, reliable systems, driving informed decision making so you can design your systems with confidence.
