Power resilience for a net zero world

Net Zero

UK businesses and public sector organisations face mounting pressure from customers, investors, and law-makers to reduce carbon emissions and achieve net zero.

In order to achieve this quickly, it is likely that all of your energy sources will need to be electrified and all of your electricity will need to be from low carbon sources. Converting everything that currently runs on fossil fuels, such as gas heating and combustion engine vehicles, to electric power will dramatically increase your electricity demands and change your usage profile. At exactly the same time you will be converting your electricity supply to renewable sources, which are more intermittent and unpredictable.

How does battery energy storage support net zero?

There are several ways that an on-site battery energy storage system can support your net zero targets.

Combining on-site renewable generation with a storage system means that you can store excess energy for use when you need it, minimising your need for top-up from the grid at peak times. For example, storing energy from solar panels when it is sunny and using it when it is cloudy. This direct, on-site use of renewable electricity is the greenest possible way of sourcing your electricity. Because it requires no infrastructure or transmission it maximises efficiency, and as a consequence also reduces your energy costs.

A battery energy storage system can also be used to enable the installation of electric vehicle chargers on your site. By acting as a buffer between the chargers and the grid connection, it can be possible to avoid expensive and slow upgrades to the grid infrastructure, electrifying your fleet significantly more quickly.

Uniquely, a Powerstar battery energy storage system has integrated Uninterruptable Power Supply (UPS) capability. Any site with critical equipment or long equipment reset times requires a UPS to prevent disruptions to their power supply. A traditional UPS loses around 10% of the stored energy during standby. For example, a 1MW UPS battery system consumes around £200,000 of electricity every year.

a Powerstar system is 98% efficient. Therefore, energy waste is cut by


Which sectors benefit most from battery storage?

Any commercial or industrial site striving to achieve net zero carbon emissions will benefit from adding battery energy storage to their electrical system.

Sites that will get maximum value from the system will be those that have a lot of roof space for solar panel installations or a need for rapid charging of electric vehicles.

Any site that also requires a reliable, uninterruptible power supply to protect critical operations will get the greatest efficiency from a combined battery energy storage and UPS system. These combined factors mean that manufacturers, distribution centres, healthcare sites, data centres and large, complex sites with multiple loads and generation will almost certainly need battery storage in order to achieve net zero as soon as possible.
