The introduction of a software-based energy management system up till now has not always been a trivial step for a company. Central topics include: mapping of the company structure in energy management, integration of the mainly partial existing metering infrastructure, or the definition of responsibilities. e-Gem helps to define the necessary procedures to archive their contents and results, and thus to provide a reliable basis for your corporate energy management.
Generally any web browser can serve as a front end for e-Gem. During development of the operating concept emphasis above all is placed on user-friendliness. From computational and energy perspectives therefore, the user can independently take over customizing his properties. e-Gem offers the possibility of individual mapping structures and responsibilities in energy management, in detail. This organization of your property includes the definition of organizational levels, metering points and their inter-relationships, physical meters, tariffs, and media.
e-Gem is capable of ideally representing your property structure. Simple management structures of a property facility or complex relationships within an industrial park are supported just the same as the basic structure of an energy provider that wants to offer their customers energy management services. The organization tree is used in addition to the classification of property and assignment of user rights. Many further modules of e-Gem generate content based on the selected tree element.
Organization levels and nodes
A division into levels of the organization provides for clear navigation; on this basis different users are granted extensive rights, and not least, attributes such as responsibilities, alert paths or relevant identification master data will be assigned to the resulting organizational units.
Central e-Gem elements such as dashboards, monitoring or reporting are always initialized based on the selected organization node and optionally on their underlying structures. The corporate structure is subject to constant change and e-Gem reproduces these property structures historically accurate. The online status is the time of access, but any time in the past is also possible. Accordingly the historically accurate, former company structure is mapped.
Energy flows (fuel consumption) in the property structure can be usefully divided according to media.
e-Gem supports any type of medium. In addition to energy sources such as electricity or steam, quantities such as well water or lubricating oil can also be managed with e-Gem. A medium is assigned a physical unit such as kWh, m³ or Nm³. When monitoring or reporting, reference can be made to the segmentation by media and meaningful relationships thus derived.
The list of media is created individually to match the industry sector or task situation of the property
Metering points are a central element in e-Gem. Metering points are associated with physical meters, derived from other meters or taken care of through free computational rules as virtual meters in the system.
Current meter readings or consumption can be observed by monitoring at all times. The value update rate is dependent on the coupling model and, based on the infrastructure, can also take place in near real time. Besides the importance of the current consumption, the historical view is also of high significance. Consumption data is archived per metering point with the necessary sampling rate, including the time stamp. This archive data can be accessed by trending or reporting at any time. Media such as active energy or welding gas are associated with the metering points with the appropriate units (kWh and Nm³). Energy consumption occurs as the corporate structure rather than as a "long list". There are feed-in meters, distribution meters, dual supplies, and partially no meters. The result is a complex network with widely branching hierarchies.
Consumption and energy flows are accurately distributed according to this structure. Furthermore a graphical representation including usage information is available, optionally filtered by medium.
Meters are the physical devices, which are mounted at the locations in the supply network, in which an energy or fuel quantity is detected and metered. Each meter point is associated with a meter in the ideal case. Which quantity from a meter point has been captured by which physical meter can thus be traced.
Meters are clearly recorded with an ID in the system. A change in the system is thus documented and can be permanently traced.
Each point of delivery can be assigned historicized rates. e-Gem allows the entry of complex tariffs with varying price components. Base price, performance price and high/low tariff support are facilitated by the accurate mapping of the costs on the basis of the consumption data.
Cost reports can be called up at any time by the user and will be sent automatically depending on the billing interval. To ensure sensitive tariff information does not get into the wrong hands, user rights can be assigned to each tariff.
e-Gem offers cost center support. Metering points are allocated a list of cost centers independent of their assigned organization node.
Based on this, full cost center reports in turn can be sent automatically to an ERP system for import or at least by E-mail to the management department. The cost center distribution within the organization tree is also presented in a clear graphic.
