Purpose

The billing of interval-related data (profiles) is called real time pricing billing (RTP billing). RTP billing allows you to define rates and prices freely across intervals and therefore enables you to structure contracts that are required in a deregulated energy market more freely.

RTP billing is based on rate models that evaluate energy requirements over a period of time. Consumption (and demand if necessary) are measured for each interval (for example ¼-hour, ½-hour) or for each rate period (for example peak and off-peak). The price for kWh of consumption, or kW/kWA demand is determined for every interval. This means the price may vary for every interval.

You can use RTP billing to calculate time-of-use pricing models and RTP models. You can define prices in advance or adjust prices to the spot price defined by the energy market.

Time-of-use pricing models are time-based. This means that prices are determined based on time groups.

RTP models are quantity-based. This means that prices are determined based on agreed reference quantities.

Process Flow

IS-U-EDM allows you to prepare for RTP billing. An internal interface transfers prepared RTP data to the IS-U billing component. Unlike conventional IS-U billing, RTP billing allows you to bill very small units of time (such as data from 15-minute intervals). These units of time correspond to the time units of the interval data measured.
