HOMER Software

Overview

HOMER is hybrid power system modelling software from UL Solutions. HOMER Pro covers off-grid and microgrid systems, optimising sizing against load profiles and resilience planning while modelling multiple generation sources including solar, wind, diesel, thermal and hydro with storage. HOMER Grid targets behind-the-meter commercial and industrial facilities and EV charging, optimising against demand charges, tariffs and energy arbitrage with solar plus storage. HOMER Front handles front-of-the-meter utility-scale hybrid projects, with multi-year dispatch modelling, market participation and bankability analysis for developers and investors. The products are built on one platform that the company says is used by more than 250,000 system designers and developers in over 190 countries, and a free trial is offered.

Editorial verdict

Fits developers and engineers sizing microgrids, commercial solar-plus-storage or utility hybrid projects, with published subscription prices and a free trial, and modelling across solar, wind, thermal, storage and grid scenarios. The trade-off is that it is a planning model rather than an operating system: it runs on-premise, has no API recorded, and results depend on the load, tariff and weather assumptions the modeller supplies; its utility-scale tier adds market participation and bankability analysis, while day-to-day monitoring and dispatch are out of scope. Teams needing live operations should pair it with a monitoring platform.
