Projections You Can Trust
Because they come from real operating data
Most sizing tools use generic assumptions and simplified dispatch logic. PLAN uses the exact same optimization algorithms that control batteries in the field with Intellect Operate.
When your system goes live, it will perform like the model predicted, because the model is the controller.
From Planning to Operations
When your project moves from development to deployment, your PLAN model becomes the foundation for Intellect Operate configuration.
No re-entering data. No translation errors. The same assumptions that drove your investment decision drive your real-time dispatch.
Frequently Asked Questions
What is a battery sizing tool?
A battery sizing tool is software that determines the optimal battery capacity (kWh) and power rating (kW) for an energy storage project. Intellect PLAN is a battery sizing tool that uses AI-powered load forecasting and the same optimization algorithms as our real-time EMS to recommend the right storage system size based on your load profile, tariff, and revenue goals.
How do I size a battery storage system?
Intellect PLAN analyzes your historical load data, utility tariff structure, and goals (demand charge reduction, TOU arbitrage, backup power) to recommend optimal battery capacity (kWh) and power rating (kW). Our battery sizing tool considers factors like cycling limits, degradation, round-trip efficiency, and revenue stacking to find the ideal energy storage sizing for your project.
What makes great battery sizing software?
Great battery sizing software uses real dispatch algorithms, not simplified assumptions, to size energy storage systems. Intellect PLAN uses the same optimization engine that controls batteries in the field with Intellect Operate. This means your storage sizing projections match real-world performance, typically within 5% accuracy.
What is energy storage financial modeling?
Energy storage financial modeling is the process of projecting the economic returns of a battery storage investment. Intellect PLAN provides complete battery financial modeling including ROI, NPV, IRR, payback period, and 15-year cash flow projections. Our energy storage financial model accounts for degradation, tariff escalation, and revenue stacking across multiple value streams.
What is load forecasting and why does it matter for battery sizing?
Load forecasting uses historical energy consumption data, weather patterns, and usage trends to predict future energy demand. Accurate load forecasting is critical for battery sizing because it determines how much storage capacity you need and when the battery should charge and discharge. Intellect PLAN uses AI-driven load forecasting to ensure your energy storage sizing matches actual demand patterns.
What data do I need to run a battery sizing analysis?
At minimum, you need 12 months of 15-minute interval load data (available from your utility) and your current tariff. For solar plus storage sizing, you can upload production data or specify system size for modeled production. Our battery sizing tool also accepts custom tariff structures and financial assumptions.
How accurate are the energy storage financial projections?
PLAN uses the same optimization algorithms that run in Intellect Operate, our production storage EMS. This means your energy storage financial modeling reflects real-world dispatch strategies, not simplified assumptions. Our customers typically see actual battery storage ROI within 5% of projections.
How does revenue stacking work for energy storage?
Revenue stacking maximizes the value of a battery storage system by combining multiple value streams: demand charge reduction, time-of-use (TOU) arbitrage, frequency regulation, capacity payments, and other grid services. Intellect PLAN models all available revenue streams simultaneously to find the optimal storage sizing and dispatch strategy that maximizes your energy storage ROI.
Can PLAN model solar plus storage hybrid systems?
Yes, Intellect PLAN models standalone storage, solar plus storage, and hybrid systems with generators. Our solar plus storage sizing tool accounts for PV production forecasts, clipping analysis, DC coupling ratios, and optimizes storage dispatch to maximize combined value. This is essential for accurate energy storage sizing in hybrid projects.
What is battery storage ROI and how is it calculated?
Battery storage ROI measures the return on investment for an energy storage project. Intellect PLAN calculates battery storage ROI by modeling all revenue streams (demand charge savings, TOU arbitrage, grid services) against total project costs over the system lifetime. Our energy storage financial modeling includes NPV, IRR, payback period, and sensitivity analysis so you can make informed investment decisions.
What is demand charge reduction and how much can I save?
Demand charges are fees based on your peak power consumption (kW), often 30-50% of commercial electricity bills. Battery storage can reduce peaks by 30-50% or more. Our battery sizing tool calculates your specific demand charge savings based on your load profile and tariff structure, and factors this into the overall energy storage financial model.
