HOMER Software Download: A Guide for Hybrid Power System Designers
If you are looking for a software tool that can help you design and optimize hybrid power systems, you may want to check out HOMER software. HOMER stands for Hybrid Optimization of Multiple Energy Resources, and it is a suite of products that can simulate, analyze and optimize various types of hybrid systems, from microgrids and distributed generation to grid-connected and utility-scale systems.
In this article, we will give you an overview of HOMER software, its features and benefits, and how to download it for your own use.
What is HOMER Software?
HOMER software is a product of UL, a global leader in safety science and renewable energy. HOMER software was originally developed at the National Renewable Energy Laboratory (NREL) and has been enhanced and distributed by UL since 2016.

HOMER software is based on a techno-economic model that combines engineering and economics in one powerful platform. It allows users to quickly and efficiently determine the least-cost options for hybrid power systems, taking into account various factors such as load profiles, resource availability, equipment costs, performance, reliability, environmental impacts and risks.
HOMER software can simulate the operation of a hybrid power system for an entire year, in time steps from one minute to one hour. It can also perform optimization and sensitivity analysis to find the best system configuration and compare thousands of alternatives under different scenarios.
What are the Benefits of HOMER Software?
HOMER software has many benefits for hybrid power system designers and developers, such as:
It can handle complex systems that involve multiple energy sources, storage devices, converters, controllers and loads.
It can model both off-grid and grid-connected systems, as well as hybrid systems that can operate in both modes.
It can account for geographic-specific criteria and risks, such as fuel price changes, load growth, accelerated battery degradation and changing weather patterns.
It can provide detailed outputs and reports that show the technical and economic performance of each system option, as well as the environmental impacts and emissions.
It can help users design more cost-effective, reliable and sustainable hybrid power systems that meet their specific needs and goals.
What are the Features of HOMER Software?
HOMER software has three main products: HOMER Pro, HOMER Grid and HOMER Optimizer. Each product has different features and capabilities depending on the type of system being modeled.
HOMER Pro is the flagship product of HOMER software. It is designed for modeling remote power systems, microgrids and islanded utilities that combine renewable and conventional generation sources with storage and load management. Some of the features of HOMER Pro are:
It can model various types of components, such as solar PV, wind turbines, diesel generators, batteries, fuel cells, hydro turbines, biomass generators, combined heat and power (CHP) units, inverters, rectifiers, converters, chargers, controllers and loads.
It can customize each component with user-defined inputs or choose from a library of pre-configured components from various manufacturers.
It can perform hourly simulations for an entire year with high-resolution data on solar radiation, wind speed, temperature and load profiles.
It can optimize the system design by finding the optimal combination of components that minimizes the total net present cost (NPC) or levelized cost of energy (LCOE) over the project lifetime.
It can perform sensitivity analysis by varying one or more input parameters over a specified range and showing how the optimal system changes with each variation.
It can generate detailed outputs and reports that show the annual energy production and consumption, cash flow analysis, greenhouse gas emissions, fuel consumption, battery cycling, unmet load events and more.
It can customize the output graphs and tables with user-defined metrics and filters.
It can export the results to Excel or other formats for further analysis or presentation.
HOMER Pro can also be enhanced with up to nine individual modules that add more functionality and flexibility to the model. These modules are:
