Powerstar Virtue energy storage solution

Powerstar Virtue is an enery storage solution that can turn large power users into a virtual power station. Large users, whether commercial, industrial, retail, educational or government, negotiate power contracts that comprise a mix of peak and off-peak tariffs. Powerstar Virtue works with the patented Powerstar VO technology and harnesses the excess voltage supplied from the grid that the VO technology would normally return to the grid to generate savings. While Powerstar VO can generate average savings of 12-15% a year, Powerstar Virtue takes this a step further. The system stores the excess and deploys it at times when the cost of power is at peak tariff, thereby producing even greater savings than using voltage optimisation alone.

By directing this excess power to storage when the cost of power is priced at the low tariff, there is sufficient stored power to go off the grid completely for two hours or reduce kilowatt usage to 50% ‘new’ power for four hours when the high tariff kicks in or during the maximum demand period. The new technology can be integrated with on-site renewable energy generation such as solar and wind, to combine the energy saved from the VO system with that generated from the renewable energy source.

As a result, users can save by switching to the stored supply at any time they wish, as well as ensuring a constant and reliable energy supply. An additional benefit is that the need for inverters on renewable installations is eliminated, which can reduce the cost and therefore improve the return on investment. In addition, because inverters inherently have power losses, which no longer occur with the new energy storage system, further savings are produced. Sites will also benefit from reduced harmonics, voltage phase balancing, improved power factor and reduced maintenance costs of electrical equipment.
