EssPro™ Grid
Battery energy storage systems
The power to control energy
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.

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.
