Energy audits are required to be carried out by law every four years for non SMEs in Germany. In order to comply with the verification and disclosure requirements, we have developed an application at JadeWeserPort that offers a simple user interface, meets the specific requirements of the port and goes far beyond the legal requirements. As we have both integrated both stationary and mobile energy consumers (ships, vehicles), it is possible to record and monitor data quickly and easily. It is necessary to record all consumers in the power grid and to subtract energy flows that are not generated by the port. This is why we have developed a digital and innovative Port Energy Consumption Management Tool (PECMT).
Master data (permanently installed consumers, vehicles, buildings and individual energy meters) as well as incoming invoices and the consumption of the devices are recorded through PECMT. When integrating devices, it is important to assign internal meter numbers so that all data can also be assigned when a device is exchanged. Using the respective masks, the devices can be stored in the system, including an indication of the location (for integrated devices) and an image, and thus quickly identified by other colleagues as the corresponding device.
PECMT offers the possibility of using the measured data to determine not only energy consumption, but also the energy sources responsible for it and consumption patterns. The tool can also be used to create CO2 estimations and balances, resulting in a complex energy data management system. Due to its success and effectiveness, PECMT has also been introduced in the other seaports of Lower Saxony (Niedersachsen Ports). Through the program, we have found a legally compliant and lean way of documenting our consumption that not only saves us time and money, but also enables us to identify and further evaluate major consumers and identify potential savings. It creates the basis for measures to be taken in order to reduce carbon emissions in the port and tackle climate change.
