Why should you choose Swiss Re corporate solutions risk engineering services?

Swiss Re Corporate Solutions Risk Engineering Services recognizes society’s ever-increasing dependence on battery power and energy storage. However, careful consideration should be given to all aspects of the design, installation and maintenance to reduce the likelihood of loss.

What are energy storage systems (ESS)?

Energy storage systems (ESS) using lithium-ion technologies enable on-site storage of electrical power for future sale or consumption and reduce or eliminate the need for fossil fuels.

What equipment is included in an energy storage system (ESS)?

Larger ESS may include a multitude of racks. Auxiliary equipment such as a Battery Management System (BMS), Power Control System (PCS), and overall Energy Storage Management System (ESMS) are typically included, especially for larger installations. Ideally, equipment will be installed in standalone enclosures dedicated solely to the ESS.

The inauguration ceremony for the BESS project. Image: EWS AG. EWS AG and MW Storage have expanded a battery storage project in Switzerland to 28MW, making it the country's largest.

How do energy storage systems work?

Energy storage systems using lithium-ion technologies generally comprise individual battery cells that are housed in protective metal or plastic casings and grouped together in larger cabinets to form modules. Typically, modules are stacked in racks that are connected in series and arranged to deliver voltage to an inverter or charger.
