HOMER Grid: Optimize Grid-Connected Energy Systems & Reduce Demand Charges
Maximize the value of your behind-the-meter energy projects with HOMER Grid. Designed specifically for commercial, industrial, and institutional users, HOMER Grid is the leading software for modeling grid-connected distributed energy systems that combine solar, storage, and other resources to lower energy costs.
Why Choose HOMER Grid?
While HOMER Pro is the standard for off-grid and microgrids, HOMER Grid focuses on the complexities of the modern utility bill. It helps you navigate complex tariff structures, demand charges, and time-of-use (TOU) rates to identify exactly how much you can save by adding solar PV, battery storage, or EV charging stations to an existing facility.
Key Features
-
Peak Shaving & Demand Charge Reduction: Automatically calculate the optimal battery size and dispatch strategy to lower monthly peak demand costs.
-
Complex Tariff Modeling: Access a massive database of global utility tariffs or create custom rates, including energy-only, demand, and fixed charges.
-
EV Charging Integration: Model the impact of electric vehicle charging stations on a building’s load and optimize charging to avoid high utility costs.
-
Resilience & Backup Analysis: Determine the “Value of Resilience” by modeling how long your system can sustain critical loads during a grid outage.
-
Step-by-Step Optimization: Find the ideal mix of PV, wind, batteries, and generators based on the lowest Total Cost of Ownership (TCO).
-
Incentive & Tax Credit Support: Include ITC, MACRS, and other local incentives directly into your financial calculations.
