Battery Energy StorageEnergy storage unlocks reserve capacity

Spinning reserves are an essential service that generators provide to help ensure stability on the grid. However, maintaining this reserve can often mean that generation resources are under-used, resulting in lost opportunities for additional energy sales. By integrating a battery energy storage system from ABB, power producers are able to release additional generation capacity and increase the profi tability of their power station.

Recapturing a lost opportunityIn most electric markets today, generators are required to maintain a electricity reserve margin that can be used in res-ponse to system reliability events such as unexpected trans-mission loss or the loss of a scheduled generator. Currently, most power producers meet this responsibility by holding back part of their generation capacity so that they are able to ramp up their output for a reliability event.

Because this reserve capacity largely goes unused, it re-presents a lost opportunity of additional energy sales to the generator. However, with an integrated ABB battery energy storage system in place to maintain the reserve margin, the generator is able to unlock additional generation capacity and increase sales.

Spinning reserves are an essential service that generators provide to help ensure stability on the grid. However, maintaining this reserve can often mean unoptimized use of generation resources and the lost opportunity of additional energy sales. By integrating a battery energy storage system from ABB, power producers are able to release additional generation capacity and increase the profitability of their power station.

For example, a 500MW coal plant with a 4% spinning reserve requirement can use a 20MW, 5MWh battery energy storage system from ABB to recover over 100GWh of additional sales per year, while still maintaining its reserve margin.

ABB BESS Technology and Offering ABB has a long history of successful energy storage solutions including over a decade of expertise in implementing battery energy storage systems. This experience gives us the capability to develop and deliver the ideal battery energy storage system to meet all power requirements. ABB integrates batteries, power converters, and system control into a single solution that will allow generators to achieve increased sales potential.

ABB Mach 2 control system

Additionally, ABB is an industry leader with the individual core technologies of energy storage like converters and control systems ranging from tens of kilowatts to hundreds of megawatts. This expertise will be essential for maximizing the benefits of using battery energy storage to unlock reserve capacity.

Improving profitability in Chile ABB recently helped deliver a 20MW battery energy storage system to a thermal plant in Chile. The solution will enable the plant to generate more electricity that otherwise would have been occupied as spinning reserves. This additional generation will lead to increased sales for the plant and also provide extra power to an electricity-hungry region.
