HOMER Front
Pros
- Industry-trusted analytical depth backed by the proven UL Solutions modeling engine.
- Advanced lifecycle degradation modeling that accounts for battery temperature and health limits.
- Detailed revenue-stacking analysis across wholesale, capacity, ancillary service, and PPA options.
- Reduces financial risk by identifying ideal component sizes before equipment is purchased.
- Evaluates projects across major global power markets using flexible import and export rules.
Cons
- The price can be steep compared with tools designed for residential or small commercial solar projects.
- No built-in visual layout features for generating 3D roof plans, site maps, or customer proposals.
- Focused entirely on analysis and planning, with no CRM, live dispatch management, or real-time control capabilities.
- Has a noticeable learning curve and requires a solid understanding of grid engineering and energy markets.
Big renewable energy projects cost a lot to get off the ground and have to navigate ever-changing power markets. Developers, financiers, and engineers constantly have to balance system sizes with battery wear-and-tear, merchant sales, and shifting capacity prices to make sure the numbers work out long-term. HOMER Front steps in to solve this, giving teams a smart analytics hub to simulate and map out the true financial viability of complex hybrid energy projects.
Built specifically for front-of-the-meter utility applications, this software takes the guesswork and risk out of early-stage planning and bidding. Thanks to smart optimization algorithms, it pinpoints the perfect mix of solar, wind, and battery storage systems (BESS) so you can tap into multiple revenue streams without wasting money on oversized capacity.
What Is HOMER Front?
HOMER Front is a cloud-based hybrid optimization app created by UL Solutions as part of its ULTRUS software family. Rather than focusing on visual layouts, it serves as a deep engineering and financial analysis tool built for project developers, investors, consultants, and grid analysts managing utility-scale systems.
Running on the trusted HOMER platform—already relied on by over 250,000 energy professionals worldwide—the app makes it easy to size and model standalone batteries or paired solar-plus-storage and wind-plus-storage setups. It runs simulations against major global power markets to show how equipment will perform when facing real-world wholesale prices, capacity payouts, and power purchase agreements (PPAs).
Features
- Hybrid system optimization: Automatically calculates the technical and financial performance of paired assets, such as solar PV, wind, and batteries, to identify the most cost-effective setup.
- Market revenue modeling: Simulates returns across multiple revenue structures, including wholesale merchant markets, capacity stacking, ancillary services, and fixed PPAs.
- State-of-health lifecycle modeling: Tracks battery degradation over time based on custom retirement rules, keeping lifecycle projections aligned with real operating conditions.
- Automated environmental calculations: Simplifies complex engineering work by automating temperature impacts and battery degradation calculations within the active storage library.
- Sensitivity analysis: Lets users define broad ranges for equipment costs, resource availability, and grid constraints to run thousands of what-if scenarios.
- Global market evaluation: Includes built-in tools for evaluating systems against major regional energy markets using customizable import and export pricing models.

How to Set Up HOMER Front
- Visit the official UL Solutions or HOMER Energy website to request access or purchase a subscription.
- Log in to the web application using your secure credentials.
- Set the project’s geographic location to retrieve local weather, solar irradiance, and market-rate data.
- Select the required battery types, solar modules, and inverters from the built-in component libraries.
- Enter economic variables such as state-of-health limits, tariff rules, and expected PPA conditions.
How to Use HOMER Front
A standard workflow in HOMER Front begins by defining the parameters of a front-of-the-meter project. Users load relevant energy-market pricing data and select the storage and renewable resources they want to evaluate. Instead of drawing panels manually, they provide a range of component sizes for the software to consider.
The simulation engine then evaluates hundreds or thousands of system combinations to determine how each hybrid configuration would operate hour by hour under different conditions. The optimization tool processes and ranks the results to identify the configurations that maximize internal rate of return (IRR).
Engineers can then use the sensitivity-analysis tools to assess how the leading designs would perform if equipment costs increased or energy-market prices declined in the future.
What You Can Manage with HOMER Front
- Hybrid system configurations: Exact sizing ratios among solar, wind, and battery assets.
- Financial performance projections: Long-term revenue analysis, including internal rate of return and capital expenditure optimization.
- Battery lifecycle models: Predictions covering battery degradation, temperature variables, and future replacement schedules.
- Revenue-stacking profiles: Charts and graphs illustrating market participation, capacity payments, ancillary services, and utility revenue.
FAQs
