On-site Generation

What is on-site power generation?

On-site power generation and generating your own electricity on-site is a powerful way to create independence from the National Grid, dramatically reduce energy costswork towards net-zero carbon emissions and create power resiliency.

Installing solar photovoltaics (PV) and wind turbines are the most common ways of reducing emissions while Combined Heat and Power units (CHP) can significantly reduce energy costs. All of these technologies have limitations that can be overcome by combining them with a battery energy storage system.

How does energy storage support on-site generation?

Battery energy storage allows excess energy generated on-site to be stored for later use, or to be sold back to the National Grid at peak pricing.

For example, solar photovoltaics (PV) will generate electricity in line with how much sunshine there is. This will not match the same profile of electricity that your site is using. You will therefore have to top-up with electricity from the grid, or waste the excess that you have generated. The reserve of energy that you store in a battery energy storage system can be used either during periods of lower generation or at peak times when grid supply comes at a premium cost. This is called peak shaving.

While renewable generation is an obvious example, battery energy storage can also support other forms of on-site generation. A Combined Heat and Power (CHP) system will ensure that energy costs and supply are under your own control. Contrary to popular belief, they do not provide full power resilience on their own. In the event of a very short-term disruption to the grid supply to the site the CHP will shut down. A battery energy storage system with Uninterruptible Power Supply (UPS) can be implemented to isolate the CHP from the grid supply and ensure that operations continue unaffected.

Which sectors benefit most from on-site generation?

Organisations from all sectors are being tasked with reducing carbon emissions and drive towards net zero carbon. This makes on-site generation an attractive and effective addition to your site’s energy infrastructure.

With the cost of solar and wind generation having steadily decreased in recent years, the combination of low cost and low carbon energy appeals to any organisation with the space available to implement such technologies. Any organisation that already has on-site generation has the scope to benefit from battery energy storage technology to maximise its effectiveness.

Combining battery energy storage with locally generated energy is particularly viable for high energy users that want to reduce their reliance on the electricity grid, minimise their carbon footprint, and protect critical equipment from being affected by power disruptions.
