HOMER Energy — Global Coverage
HOMER software, worldwide
More than 250,000 engineers, planners, and researchers in 190 countries use HOMER to design microgrids and hybrid power systems. The global standard in energy modelling—built for local realities.
Why regional context matters
Microgrid economics are local. The right technology mix for a project in Germany depends on EEG 2023 feed-in tariffs, balancing market rules, and grid connection costs—none of which apply in Chile, India, or Nigeria. HOMER models all of them. It ships with climate data for every location on earth, and its dispatch optimiser works whether you are building under EU state aid rules, Brazilian ANEEL auctions, or a World Bank Results-Based Financing framework. Whatever the regulatory context, HOMER produces bankable feasibility numbers.
