As the UK continues to move away from fossil fuels and towards renewable energy sources. Better infrastructure is needed to support the construction of energy-efficient buildings. That’s where battery energy storage systems (BESS) come in.
With BESS, you can utilise renewable energy from sources like wind or solar without facing the challenges of intermittent shortages. It’s not just about becoming more sustainable. It’s making sure the power being generated is consistent and reliable so these systems become more widely accessible across the country.
What Are Battery Energy Storage Systems (BESS)?
Battery energy storage systems are essentially large-scale rechargeable batteries for the power grid. They collect and store electricity generated from renewable sources, most commonly solar and wind. The system then releases the electricity when it’s needed.
When this technology was first introduced, it was considered to be more of a niche. But over the last decade, BESS has become much more mainstream and a core part of many construction projects. Just since 2020, the UK’s operational battery storage capacity has increased by over 500%.
Why have BESS become so important?
Battery energy storage systems fill a need in the UK’s electricity market. Weather is unpredictable, which means wind and solar don’t produce power consistently. One day, they may collect more energy than is needed. Another day, they might fall short.
BESS solve that problem by collecting the excess energy to make it available later when it’s required. This means a better balance between electricity supply and demand.
Some battery storage systems are built alongside renewable energy projects like wind farms. Others are standalone sites that are directly connected to the grid. They’re a versatile solution that creates a more flexible system and a better energy storage infrastructure.
Having a reliable BESS in place helps to support the switch to renewable energy. You can be confident that your development will have access to electricity that’s more stable, cheaper, and greener.
Why BESS is Growing in UK Construction Projects
Battery energy storage systems are quickly becoming a key part of today’s construction projects. The expansion of renewable energy isn’t the only reason for this.
Increasing pressure on the national grid is another driving factor. A lot of the grid’s infrastructure wasn’t originally designed for decentralised systems with heavy use of renewable energy. As the demand for electricity rises, BESS provide a way to reduce pressure on the grid, without major upgrades.
Then there’s the responsibility to reduce carbon emissions nationwide. The government’s Net Zero targets are encouraging developers to incorporate renewable energy in their projects. Grid scale battery systems are essential in helping them achieve those goals.
Economic factors also play a role. Energy prices have become more volatile in recent years, costing businesses more to run their operations. A renewable energy storage infrastructure like BESS helps operators to store electricity when it’s cheaper and use or sell it when prices surge.
With these factors increasing demand, BESS has now become a standard consideration in many large-scale developments.
The Role of Construction in BESS Projects
Battery storage systems are intricate renewable energy solutions that require detailed planning. The energy storage infrastructure must be built for the long-lasting function of the battery. Taking safety, regulatory standards, and maximising operational performance into consideration.
Prepare the site
Battery energy storage systems are specialist infrastructures that require well-prepared construction. They’re not just installed. They’re built into carefully designed sites. You’re dealing with complex electrical equipment, strict safety standards, and the wider energy network. All of this needs to be factored into BESS construction.
Before any equipment can be delivered, the site needs suitable preparation. Heavy battery units and other connected elements need to be supported. That means land clearance, groundworks, levelling, and drainage system installation. Strong and precise groundwork is particularly fundamental with the size and weight of the equipment involved.
Building the infrastructure
Once the site is prepared, construction teams can develop the structure to house the battery and support it. Everything around this infrastructure needs to be thought through.
Building concrete foundations, equipment bases, access roads, and secure enclosures ensures the systems are implemented securely. Anything missed at this stage could cause larger problems later on in your development.
Cable routing systems and ducting need to be installed to allow safe and efficient electrical connections site-wide.
Grid integration
Interconnectivity between battery systems, substations and the electricity network is essential. The battery needs to know when to supply the power and when to store it. Any problems with connectivity or compliance could hinder operational performance.
Detailed coordination is required here between civil works and electrical installation. With a high level of technical understanding, to make those connections happen.
Managing safety
BESS sites must be designed with electrical risks in mind. High-voltage equipment means heat generation, which means potential fire hazards. Your construction is responsible for implementing suitable safety measures.
Fire protection systems, ventilation layouts, and safe maintenance access. These ensure the protection of every staff member on site.
Following an integrated approach
Construction contractors are typically the main point of contact for coordinating a BESS project. Large-scale developments require multiple teams and good communication.
Developers, engineers, equipment suppliers, and grid operators all need to do their part. On time and following the right specification. An integrated approach helps to effectively manage the complexity of battery energy storage system construction.
