General / Introduction:

To be offered is a cloud-based energy management system optimized for energy data collection, analysis, and energy efficiency improvement.

The energy management software should be designed for company-wide and cross-site monitoring and optimization of energy consumption. It is to be used both as a single-site solution and as a group solution to increase energy efficiency across all sites and thus contribute significantly to reducing overall costs.

The energy management system provides energy and facility managers precise energy consumption data for monitoring, measuring, and analyzing energy consumption.

The goal is to collect all energy and media-relevant data in a cloud-based and homogeneous system. This requires an energy management system that takes data from a partially heterogeneously structured system landscape. Accordingly, automatic data acquisition for measuring devices, sensors and other communication-capable electronic equipment and the acquisition and monitoring of line-bound media (e.g., water, compressed air, gas, steam) is a key function of the cloud-based energy management system in combination with different measuring devices.

The cloud-based energy management system supports a variety of functions:

• Access to customized dashboards with actual values and historical data, status displays and alarms.
• Charts: graphical representation of any combination of measured data; checking the consistency and plausibility of consumption data.

Furthermore, a user without programming knowledge should be able to define new key performance indicators (KPI) and output them in the form of reports or dashboards.

Data acquisition and export:

The existing system landscape requires data transfer from existing SCADA or process control systems. In addition, values from the field level are to be transferred via gateways or IOT-capable devices.

The gateways are to be configured via a web interface. Furthermore, it should be possible to make changes to the configuration via the superimposed cloud system without having to connect to the gateway.

In addition to the hardware gateways, there are to be other options for writing data to the cloud. Here, for example, a module-based PLC library or other software solutions should be mentioned.

Data processing:

The system should provide a way to link values before storing them in the database. These can be physical values (e.g., power consumption) as well as production data (e.g., number of pieces). For this, different mathematical functions are required, such as the condensation of second values to 15min values, a conditional averaging, or the determination of minimum and maximum values.

The recording and monitoring of greenhouse gas emissions such as CO2, NOX, etc. should also be supported. CO2 monitoring for automatic and plant-specific evaluation of material flows with emission and oxidation factors according to the standard or mass balance method should be possible.

Monitoring:

Monitoring functionality is required for the timely observation/validation of energy and consumption values. The evaluation and display (monitoring) are required not only for current values, but also for historical values from the database.

It should be possible to display up to 10 hydrographs simultaneously in one chart tool. It must be possible to display up to 3 Y-axes in one chart. The temporal resolution is to be freely selected by the user. The display as line, bar, or dot diagram should be freely selectable.

In a dashboard, several data points must be able to be displayed at the same time, whereby, for example, a display of daily, monthly, and annual values in a single overview is given. Possible display formats are bar charts, pie charts, line charts, numerical values, values in, difference values to reference data points, display as a gauge.

The current energy and media flows are to be visualized in the form of energy flows in a dynamic process diagram Sankey diagrams.

Controlling:

The system must support the calculation of key figures. Furthermore, it must be possible to balance energy flows to determine production-related key figures, target/actual analyses of energy consumption or costs for different time periods. Characteristic values such as efficiency ratios should be calculated and graphical evaluations such as annual duration curves, hourly distributions, weekly and daily curves of any time periods should be output (minimum: 15-minute grid).

The key figures determined in the system should be able to be compared with benchmarks and target values and thus enable the comparison of sites or plants.

Meter Management

In addition to power and consumption data or flow rate and quantity, it must also be possible to record and store ascending meter readings. Corresponding configuration options must be available in the energy management system to be able to configure a meter constant and the counting range up to an overflow.

The system must be able to correctly process multiple overflows in a calculation interval. It must be possible to configure a possible meter exchange subsequently. It must be considered that a new counter may have a different counter constant.
