Intelligently reduce the peak power you buy from the utility each month. Determine the best mix of resources for the least-cost solution, and design a system with the highest possible rate of return.
One plus one plus one can equal more than three if you optimize to stack value. Understand your ROI from combining value from demand charge reduction, energy arbitrage, and self-consumption.
The HOMER® optimization engine is trusted by over 150,000 users worldwide. Examine all possible combinations of system types in a single run, to find the best combination for your system.
Combined Heat & Power
Combined heat and power are essential elements in many building or campus sytems. HOMER Grid lets you include Combined Heat and Power in your design, helping you understand its interaction with other DER to get the full picture of your economic options.
Robust Storage Model
The HOMER storage model is the most accurate and sophisticated model on the market, based on the input of thousands of users. HOMER Grid accurately models battery life and performance for the duration of your project, so you know exactly what to expect.
HOMER Grid’s dispatch is built on the HOMER engine - the global standard in distributed generation design. HOMER Grid’s dispatch strategy uses a “look ahead” approach to pick the best economic options for serving your load at each timestep - based on tariffs, weather, and available power components.
Model EV Charging Costs
Save on utility costs with a charging system designed for the optimal mix of renewable energy and storage whether managing a fleet of vehicles or an on-demand EV charging model. This feature lets you plan for single or multiple chargers and Level 2 or fast-charging DCFC stations.
Accurate Tariff Modeling
Accurately model complex, custom utility tariffs around the world, or select existing tariffs from our library.
Tailor your design to the exact needs of your project. HOMER Grid has options for solar plus storage, generators, combined heat and power, wind, and more.
Accurate results help you understand risks, see costs, and quickly answer specific questions, like “What’s the optimal system design to reduce demand charges?” and “What’s the IRR of each possible system?”
Dig Deep into
There are no black boxes here - only well displayed details. HOMER Grid produces thousands of graphical results, so you can see the details of how each modeled system will operate.
You can't control the future, but you can understand the cost of being wrong. Sensitivity analyses let you easily compare scenarios, so you understand the potential impact of changes and uncertainty.
Combine the power of your favorite solar modeling tool, like HelioScope, with HOMER Grid for more accurate modeling and more bankable results.
Global Resource Data
HOMER Grid fetches solar data from NREL and NASA databases, or upload your own measured or purchased resource data.
Provide an additional value stream by proving the value of a hybrid/generator project in extended outages.
