Switchgear and substation power systems work together to deliver electric power and mitigate potential electrical faults downstream in the electrical generation process ensuring safe electrical power.

With the power utility landscape changing in terms of both architecture and methods of generation, the need for reliable energy storage solutions to support this evolution is paramount. Substations are evolving and adapting to support new and varied generation sources including not just coal and natural gas, but also nuclear, wind, solar and other renewable resources. This change is creating unique energy storage requirements that support the variable nature of the renewable generation sources.

Enersys® provides both product and service solutions to allow switchgear and substations to operate safely and continuously. We are continually advancing our energy storage solutions to offer greater reliability, longer service life and reduced maintenance. VLA flat plate, OPz tubular and VRLA options such as Thin Plate Pure Lead (TPPL) technology with high energy density optimize energy use and space within electrical infrastructure to maximize output and minimize space. Space saving enclosures will protect against unauthorized access and damaging effects of the environment, new technology charging systems and all other associated power distribution panels make EnerSys a one stop shop for your site.

Our worldwide footprint and local infrastructure support the installation, maintenance and end-of-life recycling processes for your global switchgear, control and power generation support.




Our charging solutions are designed for stationary batteries in utility and industrial applications involving power generation, transmission and distribution.


With a choice of many batteries designed specifically to support switchgears and substations, the EnerSys® PowerSafe® battery ranges let you select the best solution for your application.
