Electrical power audit
Electricity audit is an analysis of the possibilities of reducing the energy consumption of electrical appliances and elElectricity audit is the analysis of the possibilities to reduce the energy consumed by electrical appliances and installations which operate in buildings. The analyzed equipment includes i.a.: transformers, motors, infrastructure media pumps, power grids, compressed air systems and lighting.
Purpose and scope of electrical power audit
As a part of the study, we prepare a concept of optimization of electricity consumption in internal transmission networks. Precise measurements are performed with the use of specialized meters- these are the basis for power distribution assessment which, in turn, makes it possible to build a baseline electricity consumption profile at the plant / network balance limit and to identify the points with increased energy consumption or reduced energy quality points, and further to determine distribution losses.
Scope of research and analysis:
- analysis of the power supply system, including the power distribution per individual receiver currently applied,
- analysis of the compressed air production system,
- analysis of the ventilation and air conditioning systems (control and adjustment),
- analysis of the extraction systems installed over the stations (control and adjustment),
- analysis of the losses on individual components of the distribution system,,
- analysis of the efficiency of a transformer (mobility measurements),
- analysis of the technical condition of switchboards, including thermal imaging,
- analysis of the energy security of the installation (including power supply security),
- analysis of the lighting installation.
Measurements for the above specified scope:
- transformer losses measurement,
- measurements of the efficiency of air compressors and of the air leakage of compressed air systems (using a compressed air flow meter),
- measurement of electrical processes of propulsion systems,
- measurements of energy consumption and illumination,
- measurements of power distribution and quality of electricity.
The summary of the audit includes the presentation of economic effects achieved through implemented changes, together with approximate costs of recommended implementations and savings resulting from the upgraded system operation.

Overall, in consequence of the audit recommendations within the scope of electrical power, DBE's clients reduced their energy consumption by approximately 94 GWh and thus achieved the average annual savings of nearly USD 10.5 million. The total payback period covering all investments slightly exceeded 2.5 years.
