Benefits of Energy Storage

The benefits of energy storage as afforded through the VIRTUE system are to deliver fundamental improvements to the way that electricity is generated, delivered and consumed. VIRTUE significantly contributes to achieving a secure and reliable energy supply.

The VIRTUE system is not an off the shelf product, it is an engineered solution which is designed to match the bespoke challenges facing businesses. As a result, each VIRTUE system is designed, manufactured and engineered specifically for each client to achieve maximum efficiency and savings.


    • Reduce: Electricity consumption from the grid by using the UPS capabilities of VIRTUE during peak times
  • Store: VIRTUE allows sites to draw and store onsite renewable sources and energy at off-peak times when electricity is cheaper and it would normally be wasted
  • Save: Switch to stored power at any time to maximise revenues and save energy and protect production costs
  • Eliminate: Operational risks through the full load UPS capabilities of the VIRTUE system

Along with grid energy storage, VIRTUE is also able to enhance the use of renewable energy sources by improving the reliability of renewable generation and maximising the benefits of wind and solar generation, in turn reducing the dependency on fossil fuels.
