Hybrid Optimization of Multiple Energy Resources (HOMER) model

Hybrid Optimization of Multiple Energy Resources (HOMER) is the global standard in microgrid software.

The software is based on decades of listening to the needs of users around the world with experience in designing and deploying microgrids and distributed power systems that can include a combination of renewable power sources, storage, and fossil-based generation (either through a local generator or a power grid).

The HOMER model greatly simplifies the task of designing hybrid renewable microgrids, whether remote or attached to a larger grid. HOMER’s optimization and sensitivity analysis algorithms allow you to evaluate the economic and technical feasibility of a large number of technology options and to account for variations in technology costs, electric load, and energy resource availability.

Key questions addressed:

  • What components should I include in the power system design?
  • How many and what size of each component should I use?
  • Is it feasible to meet electric demand under a given system configuration?

Sample data inputs:

  • Load inputs
  • Technology options
  • Component costs
  • Sizes and numbers of each component
  • Resource availability

Sample quantitative outputs:

  • Feasible system configurations
