Optimize one charge at a time and the pieces fight each other. TARSIS solves every part of the tariff together, to the exact optimum.
It optimizes time-of-use, demand tiers and export together, not one line at a time. Exact mixed-integer optimization of the full tariff.
Some tariffs charge on the utility's system peak, not yours. TARSIS models it. Coincident-peak charge modeling.
A single peak can inflate your bill for a year. TARSIS plans around the ratchet. 12-month ratchet modeling.
Every site is solved against its actual current tariff, kept current. 200+ US utility tariff structures.
Our validation methodology is a walk-forward backtest against standard baselines with Diebold–Mariano significance testing — designed to run on your own history during onboarding so you can see how it performs before you rely on it.
These are the real methods behind TARSIS, each in one plain line. We name the method as a credibility signal — we don't publish the recipe.
Solves the whole bill at once, to the exact optimum.
Handles the charges simple controllers miss.
