From the Sun to the Site: ESS Power Store Introduces Renewable Pre-Charging for Battery Storage

The transition away from diesel-powered temporary energy isn’t simply about replacing a generator with a battery. At ESS Power Store, we believe the source of the energy going into that battery matters too.
That’s why we’re pleased to introduce the next stage in our approach to cleaner temporary power: our RoyPow Power Store units and PC15KT Battery Energy Storage Systems (BESS) can now be supplied pre-charged using renewable energy generated from Solar PV.

Charged by Solar. Ready for Site.

Battery Energy Storage Systems are already transforming the way temporary and mobile power is delivered across construction, events, film and television, infrastructure and industrial applications.


Unlike conventional diesel generators, a BESS can provide power without an engine constantly running. This means zero local exhaust emissions during battery operation, significantly reduced noise and considerably less maintenance.


However, there is another part of the sustainability equation: where did the electricity used to charge the battery come from?
ESS Power Store is addressing this by using Solar PV-generated renewable electricity to charge our Power Store fleet. Units can therefore leave us pre-charged with renewable energy, ready to be deployed to the customer.


It creates a simple energy journey:
Sunlight → Solar PV → Battery Storage → Customer Site → Clean Power

Renewable Energy in a Portable Format

The concept is particularly powerful for temporary power.


Solar generation doesn’t necessarily have to be located where the electricity is ultimately consumed. By generating renewable electricity at our charging location and storing that energy within the BESS, we can effectively transport stored renewable electricity to where it is needed.


Our RoyPow Power Store units provide a flexible solution for applications requiring clean, quiet and dependable temporary power. Alongside them, the RoyPow PC15KT provides another highly portable BESS option for applications where compact, mobile energy storage is required.


Both are now available from ESS Power Store pre-charged from our renewable Solar PV supply.

Moving Beyond Diesel

For decades, temporary power has largely meant diesel generation. While generators remain necessary for some applications, battery storage provides businesses with an opportunity to significantly reduce generator runtime and, in appropriate applications, remove the generator altogether.


This can deliver several operational and environmental advantages, including:

  • Zero local exhaust emissions when operating from battery power
  • Solar PV renewable pre-charging
  • Reduced dependence on diesel
  • Significantly quieter operation
  • Reduced idling and unnecessary fuel consumption
  • Greater suitability for noise-sensitive and urban locations
  • Improved energy and carbon reporting opportunities
  • This makes BESS particularly attractive for construction sites, events, film and TV production, utilities, infrastructure projects and temporary facilities.

Making Temporary Power Smarter

The next generation of temporary power isn’t only about replacing one energy source with another. It’s about understanding how energy is generated, stored, transported and consumed.


By combining BESS technology with Solar PV, monitoring and energy data, ESS Power Store can help customers understand how much energy they’re using, while identifying opportunities to reduce diesel consumption and associated emissions.


For organisations with increasingly demanding sustainability, ESG and carbon reduction targets, this provides a practical way of demonstrating progress.

Our objective is simple: make lower-carbon temporary power easier to deploy.


By pre-charging our RoyPow Power Store and PC15KT units using renewable Solar PV electricity, we’re creating a cleaner energy cycle before the equipment even reaches site.


Instead of simply delivering a battery, we’re delivering stored renewable energy that’s ready to work.
