SOLVES YOUR WHOLE UTILITY BILL AS ONE PROBLEM

Time-of-use, demand charges and export pull in different directions, and the trickiest charges — the ones tied to the utility's own peak, or a single spike that inflates your bill for a year — trip up simple controllers. TARSIS solves the whole bill exactly, including the parts most tools ignore. Exact mixed-integer optimisation modelling coincident-peak charges and the 12-month ratchet.
