With decades of expertise in generator-led critical power, we enable data centre owners to design and deliver their own energy solutions – faster and with greater confidence.

Fastest route to operational readiness

Whether you are building new capacity or upgrading existing systems, PSE’s proven delivery model ensures the fastest route to operational readiness

Why Battery Energy Storage?

As data centres and critical facilities face growing power demand and new ESG requirements, battery energy storage plays an essential role in modern energy strategies:

Optimise energy use and costs — charge during low-demand periods, discharge at peak demand

Support sustainability targets — reduce reliance on fossil-fuel generators

Expert-led design of long-term, future-proof energy systems

Enable grid flexibility — participate in demand response and grid services

Future-proof your power architecture — scalable for tomorrow’s needs
