HOMER® Pro
Multi-Year Module
Multi-Year Module
The Multi-Year module allows you to model changes that can occur over the course of a project. PV degradation, grid price escalation, load growth, and fuel price escalation are a few of the model parameters that you can include in a HOMER model with the Multi-Year module.
Utility-Scale Developers & IPPs
Produce bankable, multi-year revenue and cost projections for hybrid project financing — accounting for PV degradation, load growth, and fuel escalation over the full project life.
Explore Developer Solutions →Utilities & Grid Operators
Plan generation portfolios and DER investments over 20–30 year planning horizons, with year-by-year dispatch results that reflect changing grid tariffs and demand growth.
Explore Utility Solutions →Engineering Consultants & EPCs
Deliver credible feasibility studies and lifecycle cost analyses that incorporate realistic degradation and escalation assumptions — improving project confidence for lenders and investors.

The Multi-Year module allows you to specify degradation or growth in terms of a percentage each year. You can also enter a year-by-year series of multipliers to match a forecast that isn't simply a percentage per year.
The Multi-Year module adds several features to HOMER's results. You can look at each year of the project life in the Simulation Results. The Multi-Year module also adds the Multi-Year plot, which allows you to plot any result quantity over the life of the project.
Using the Multi-Year module with the Advanced Storage module will unlock the full potential of both. The Advanced Storage module includes the ability to model battery performance degradation over the battery lifetime. This aspect of the Advanced Storage module is only available if you have the Multi-Year module.
