BESS Energy Storage System for Low and Medium Voltage and the Need for Decarbonisation of the Grid 40 energetica INDIA- Mar_2022 To successfully achieve the next step of the energy transition, additional grid supporting components and mar- kets are needed, to properly balance the grid while less conventional pow- er plants are available. Smart energy consumption, cost-cutting, resilience, resource-saving, environmental effi - ciency—this is not a complete list of benefits offered by a battery energy storage system (BESS). With a wide range of power and storage capacity, BESSs vary from small-sized house- hold devices to large-scale systems used for utilities and industrial applications. Battery Energy Storage Systems (“BESS”) are infrastructure technol- ogies that can store large amounts of energy for an electricity grid. BESS projects are currently very profitable. Should the need arise, the electrochem- ical energy is discharged from the bat- tery and supplied to homes, electric vehicles, industrial and commercial fa- cilities. In emerging countries such as India and SEA, unlevered investment payback periods for BESS projects are 3 – 5 years. Homeowners with rooftop solar may have come across home energy batter- ies (the size of a large appliance). These batteries store energy to power homes in the evening (called “Energy Shift- ing”) or during brownouts. Although various flexibility options are considered for these tasks, battery energy storage systems (BESS) are currently one of the most promising candidates to fill this gap. Technical - ly, these systems are characterized by the fact that they can provide a large amount of energy very quickly and with high efficiencies. Meanwhile, safe - ty, reliability, and lifetime have reached a considerable level and, at the same time, costs have dropped significantly We are in a stage in which storage systems are increasingly being imple- mented to take over tasks that would not have been economically feasible a short time ago. Therefore, many in- vestors are currently ready to invest in these applications and are looking for new areas in which storage systems can be prosperous business opportuni- ty. Unfortunately, regulatory hurdles still exist in many countries, because of the difficulties to identify the role of energy storage within the traditional power system structure of generation, transmission/distribution, and con- sumption. Overview of the most important appli- cations that can be realized with the help of BESS based on the categories of the European Association for Storage of Energy This view on the selected applications has followed the steps to first introduce them, investigate on location specific criteria, and finally provide insights on market size as well as suitable technol- ogies. We are in a stage in which storage systems are increasingly being implemented to take over tasks that would not have been eco- nomically feasible a short time ago. Therefore, many investors are currently ready to invest in these applications and are looking for new areas in which storage systems can be prosperous business opportunity. A.K.
