Power Resilience

Power Resilience refers to the ability to continue your operations without impact from disruption to your power supply.

As we electrify more of what we do, and we transition to a larger share of green energy in the UK Energy mix, we put ourselves at greater risk from power disruption, which can have significant financial implications. This is not just a risk of a power cut, as there are many types of power disruption that can damage or interrupt your electrical equipment.

We can provide full power resilience to a whole site through any combination of our core technologies:

Battery Energy Storage Systems (BESS)

Battery energy systems have a wide variety of uses such as they can be used to realise the full benefits of CO2 reduction technologies, like on-site solar and wind power generation, Electric Vehicle charging and feedback of power to the grid.

A BESS can be used to replace a UPS system & unlike traditional UPS systems our BESS also creates the option to generate extra revenue through grid services.

We are the only Battery Energy Storage company to achieve HTM (Health Technical Memoranda) compliance for NHS installations & the only company to install a Battery Energy Storage System and UPS for the NHS to date.

Voltage Optimisation

Optimising your voltage, will reduce your commercial energy use and costs as well as lowering your carbon footprint and CO2 emissions at the same time. It could also save on costly repair bills for your electrical equipment.


Transformers play a critical role in the energy infrastructure of the UK as a whole, as well as that of many individual organisations. We are the UK's largest manufacturer of UK-manufactured Super Low-loss amorphous core transformers.

Uninterruptible Power Supplies (UPS)

Powerstar UPS solutions are a combination of a highly sophisticated Battery Energy Storage System (BESS) and a control system. It features ultra-fast switching to connect the battery to your site supply

Energy Managemnt Software

Powerstar’s power and energy management software empowers you to make smart decisions about your site and your energy by monitoring and managing your energy usage.

Uniquely, our resilience technologies can also be used to provide your site with additional applications and benefits. While most UPS power solutions provide just that, our bespoke solutions provide better control over your energy usage, reduce bills and carbon emissions, improve sustainability, make your power more resilient, and more.

We call this Resilience+

Power Resilience

Power Resilience as part of the Energy Trilemma

As one of the three pillars of the energy trilemma and the area the UK scores lowest on the world Energy Trilemma index. At times last winter the UK had an excess capacity of just 6.6% which is considerably lower than the year before. The continual transition to more generation from renewable sources will only increase the risk of blackouts and brownouts in the years to come.

Ensuring your business has built in resilience and access to a resiliant power supply will be key to ensuring valuable production days are not lost. While Diesel generators can provide backup power, they can significantly increase your carbon footprint at a time when most businesses are aiming to achieve Net zero emissions.
