Cost of Energy

Get Simplified Tariff

Get a simplified, indicative view of a Tariff’s rates over a time range.

The response is a set of rate timeseries, one per (input dataset, rate unit). In each interval, rate is what is paid per kWh of energy on the input (for per-kWh series) or per kW of power peak derived from the input (for per-kW series), in the series’ own currency.

This is an approximation of the tariff’s price shape, meant for heuristics that need a coarse “when is energy cheap/expensive” signal — not for exact cost calculation or optimisation.

Components that don’t fit a simple per-kWh or per-kW rate (fixed fees, spot-price-linked charges, overdraft fees …) are surfaced by name and applicability window in unprojectable_components rather than appearing in the rate timeseries.

Use Calculate Tariff for exact cost calculation, or In Optimisation for using tariffs in optimisation models.
