OUR TECHNOLOGY POWERS A MORE RESILIENT FUTURE
EnerSys technologies are essential in building a more energy-resilient future—by enabling operational independence and enhancing system-wide efficiency. We define resilient, climate technology not only as a solution that reduces more carbon than it emits over its lifecycle, but also as one that strengthens energy security through smarter infrastructure. Many of our offerings meet this standard, helping customers optimise power use and reduce dependency on volatile energy markets.
Our batteries and integrated energy systems enhance grid flexibility and stability by bridging the gap between intermittent renewable sources, like wind and solar, and consistent power demand—ensuring energy is reliably available when and where it's needed. By enabling the use of lower-cost, lower-carbon energy sources, our solutions help stabilise the grid, reduce energy costs, and support customers in meeting reliability targets and advancing long-term energy strategies.
In financial year 2025, EnerSys delivered over 12 gigawatt hours of energy storage capacity - enough to support sustainable, secure power for numerous communities and industries. Our technology enables broader integration of renewables, enhancing energy reliability and building resilience against power disruptions in an increasingly complex energy landscape.
We prioritise innovation and safety, dedicating extensive resources to research, testing, and compliance. To uphold the highest standards, we maintain rigorous certifications across sectors, including AS9100 for aerospace, ISO 13485 for medical, ISO 26262 for Lithium-ion motive power, and TL9000 for telecoms.
