A BESS can provide a wide array of services to the end-user. As a system integrator, ATS Group is considering all possible applications of such a BESS. However, each dedicated application does have implications to the practical integration. With the final decision in relation to its intended operation, which is focusing on energy optimization, as with the selection of the supplier of the system, the BESS project is fully on track!
A BESS allows flexible energy flow management. The system can be integrated with the focus to optimize the consumption of locally generated renewable electricity. Subsequently, the system can make use of the difference between day and night tarification, or perform peak shaving, in order to reduce the actual energy bill. The end user can utilize auxiliary services, such as the mitigation of harmonic distortion, the compensation of reactive energy or provide power as a backup unit.
At the start, even before the actual design phase, the choice of operation of the BESS is to be selected. The final decision does have a significant impact on the power ratio, the battery and the practical integration. ATS Group and EDF Luminus gave the priority towards energy optimization, combined with the maximization of auxiliary services such as back up power and UPS functionality. Those services closely relate to the core business of ATS Group.
The final application is fundamental in order to request a dedicated study from the network operator. The close collaboration between the network operator and the medium voltage department of ATS Group resulted in an innovative integration of the BESS into the grid. This did not only comply with all the required technical requirements, but also resulted in a positive effect on the total cost of ownership.
Based on the criteria, a selection of the supplier has been made. The final decision was in favor of ABB, who is suggesting a unique modular concept both in power as in total concept. In return, ABB does rely on the services provided by the department Panel Building of ATS. In addition the safety and security issues are taken into consideration. The overall concept is tailor made for the SME, which is searching for answers in an era on energy transition.
For the actual integration and to seamlessly coordinate all the energy flows, a monitoring and control platform is needed. At this stage the BU Automation and BU Building Automation will play a key role.
