Keaflow optimizes the sizing of distributed energy systems — technically and economically, precise and transparent. No Excel sheets with averages, no rules of thumb, no guessed system sizes.
Most sizing happens in Excel models that scale up a "typical day." Component sizes are guessed, then iteratively adjusted. Economics gets calculated in a second tool, PV in a third, subsidy eligibility in a fourth.
Professional optimization tools exist — but they are complex and far from practice-oriented. They solve the math problem but don't translate it into the daily workflow of consultancies and planning offices.
The result: slow proposals, oversized systems, missed subsidies, weak business cases.
Instead of separate models for sizing, economics, and PV, you get optimized component sizes, an hourly dispatch schedule, and complete financial metrics in a single run.
Technical sizing, financial analysis, and PV planning in one integrated optimization — no tool switching, no model breaks.
The cost-optimal size of every component — solved together with the hourly dispatch schedule in one step. Heat, power, and cooling in a single model.
TCO, NPV, IRR, ROI, LCOE/LCOH/LCOC, nominal and discounted payback, full cashflow. Automatically from the same optimization — not from a separate Excel.
Self-consumption, feed-in tariffs, subsidy eligibility, and storage cycles are co-optimized. PV size follows from the economics, not from a rule of thumb.
From a single PV system to a sector-coupled district — Keaflow runs the projects you work on every day.
Calculate the optimal PV size and storage capacity together. Self-consumption rate, feed-in tariffs, and storage cycles are co-optimized — not derived from rules of thumb. For commercial, industrial, and multi-family buildings.
Gas boiler out — what comes in? Keaflow compares heat pumps, hybrid solutions, pellet boilers, and CHP units against the existing system. Including subsidy eligibility and an hourly dispatch schedule across the full year.
Heat pump plus PV plus battery plus thermal storage — what runs when, and at what size does each pay off? Keaflow solves the coupling in one model instead of three separate tools.
Compression chillers, absorption cooling, free cooling, cold storage. For office buildings, production sites, and data centers with high year-round cooling demand.
Economically viable CHP sizes for industry and districts. Heat-led versus power-led operation is evaluated head-to-head — including peak-load boilers and thermal storage.
Multiple buildings, multiple energy carriers, one energy concept. Keaflow consolidates load profiles and optimizes central supply — ideal for utilities and project developers.
Hourly dispatch, annual load duration curve, energy flows, subsidy eligibility. Print-ready in one click — what otherwise takes days of copy-pasting between tools.
