1 EssPro Grid Battery energy storage systems The power to control energy

2 EssPro Grid gives you the power to control energy helping to keep smart grids in balance Maximizing the value and performance of energy storage EssPro Grid With over a decade of experience, ABB is a pioneer and technology leader in the field of distributed battery energy storage systems (BESS). The EssPro Grid portfolio offers fully integrated, reliable and safe storage solutions for a wide range of applications. As the demand for cleaner, safer and more reliable power increases, so does the need for a smarter electrical grid that can respond to the growing needs of system operators and consumers. Having the ability to instantly store and dispatch electricity when needed will enable a more flexible and responsive energy infrastructure. Strategically placed energy storage systems throughout the electrical grid can increase the operational performance and reliability of the utility network, better integrate alternative energy sources, balance electricity supply and demand, and ensure that energy is readily available when primary power sources are interrupted. Energy storage benefits the entire power value chain, from generation, transmission and distribution, all the way to users. 2 EssPro Grid ABB

3 Energy storage applications Application EssPro Grid benefits Frequency regulation EssPro Grid absorbs and injects power in order to keep grid frequency within pre-set limits. Spinning reserve To provide effective spinning reserve, the EssPro Grid is at an adequate level of charge ensuring fast response to generation or transmission outages. Capacity firming EssPro Grid smoothes the output and controls the ramp rate of wind and solar power generation to mitigate rapid voltage and power fluctuations caused by their variable nature. Peak shaving EssPro Grid can be installed close to loads and shift expensive peak load to low tariff times. Power quality EssPro Grid eliminates short voltage sags eg, caused by power system faults or the start-up of a large motor. Uninterruptable power supply In case of a mains failure or blackout, EssPro Grid can bridge the gap in supply. Load leveling EssPro Grid stores power during low-load periods and delivers it during periods of high demand in order to reduce the load on less economical peak-generating facilities. Voltage support To help maintain the grid voltage, EssPro Grid injects or absorbs both active and reactive power. ABB EssPro Grid 3
