Internal Billing

Due to the high cost of energy  allocation to the individual consumer is essential. Besides the mere passing on of costs and the ensuing transparency this is an important (educational) factor to save energy.

In practice, however, the meter structures rarely coincide with the user structures, i.e. departments or tenants will only be considered by meters proportionally. This is due to the fact that meter structures are not changed in years, user structures, however, usually do not persist a long time.  Furthermore, meter structures are based on buildings, floors, machinery or equipment, but not on the current user situation. In practice, the total energy costs of the utility bill mainly are allocated according to area shares or, otherwise, by partially imprecise keys making a user-based allocation impossible.

WiriTec BL has been developed by WiriTec GmbH to solve this problem and facilitate a fair cost allocation.

WiriTec BL offers a variety of ways to adequately process your energy data to enable internal cost allocation and to verify your utility bills.

Thus, for example, measured consumption data can be provided with surcharges or discounts to illustrate production stops or specific process features. If necessary, physically conditioned conduction or conversion losses (i.e. in the case of transformers) will be allocated by defined keys to individual cost centers through residual value repartition. In cost allocation, the repartition as per utilization degree allows to automatically consider special utilization cases, such as production increases or supplementary shifts, through the use of respective factors.


By means of the appropriate user rights, the respective user will be provided with each calculation in the course of the individual processing steps for review and approval. This way, the various approval and review processes within organizations can be easily illustrated.

WiriTec BL automatically ensures that the defined settlement workflow is being adhered to at all times and that potential necessary repetitions within approval procedures are being carried out, thus  resulting in a sound consumer-based accounting record.
Upon approval by the one in charge the accounting record will automatically be transferred to the associated accounting systems via specific interfaces.
