Shenton Group Complete Generator Installation at London Data Centre

Another Data Centre can have total peace of mind in the knowledge that Shenton Group have installed a generator for them to protect their business. When looking to complete a generator installation, it is crucial to consult the experts to audit the site, to ensure you have the equipment you need to keep the power on at your data centre site.

Generator Installation Requirements for Data Centre 

Our client required 2 x 220 kVA, 3 phase Generators to allow syncing to the customer’s Common Bus Connection. The instalation included new Deep Sea 8610 Controllers, downstream changeover panels (400A 3 phase with Deep Sea 333 controllers), and new ABB motorised MCCB’s.

One of our fully qualified generator installation Project Managers worked very closely with the customer’s electrical installers on this 1st phase, leading to a smooth project throughout design, installation and the onsite witness test—another successful Generator installation from Shenton Group.

How Much Does It Cost to Install a Generator?

The total cost of generator installation is dependent on many factors, including the equipment required, the size of the generator/ number of generators, and if it’s a standard or bespoke solution. If you invest in a generator, you must ensure correct integration, and consider ongoing maintenance so the equipment can be relied on in the event of an outage. A power outage at a data centre could be catastrophic. The ramifications can include loss of data, money, customers and reputation. Therefore it is invaluable to have a reliable backup generator solution in place. The best way to establish the costs involved is to book a site survey, and we can then provide an accurate quotation. We can also offer guidance on generator maintenance plans best suited to your requirements.

Generator Installation Services

We provide a full suite of generator installation services right from the design and manufacture, to project management, install/site integration, testing and ongoing maintenance. We provide full turnkey installations.

Shenton Site Survey’s Ensure The Correct Solution

A site survey will help the Shenton Group engineers to understand your exact requirements. Prior to a generator installation, we will work with you to establish your electrical demand and clarify how long you need a backup power system to run in the event of a power outage. A backup generator alone will kick in within 10-15 seconds after a power outage, but if teamed with a UPS (Uninterruptible Power Supply), there will be no downtime at all. All critical applications such as data centres and healthcare facilities use generators and UPSs in tandem. 

Backup power solutions consisting of a UPS and no generators are suitable for organisations that can afford some downtime. A UPS safeguards equipment in a power outage, temporarily protecting it from immediate power loss, potential damage or malfunction, and provides time for you to shut down and turn off equipment safely. UPS only backup solutions can be relied upon for periods ranging from just a couple of minutes right up to 2 hours. This timeframe is dictated by the size and amount of UPS batteries and the electrical load it needs to support. However, installing a generator would be the answer if there is a requirement for the power to remain on and protect you for more extended periods. Each use case is different, and every customer of ours has different needs, which is why a site survey is essential.

Design & Standby Generator Installation

A carefully designed backup power solution will ensure you have all the equipment you need to avoid any issues during power loss.

Whether you require an internal or external installation, we will provide a complete turnkey project, including:

  • Design
  • Manufacture
  • Project Management
  • Civils
  • Mechanical and Electrical Installation
  • Site Integration
  • Testing
  • Final Commissioning

What Is ‘Peak Lopping’ And How Can It Help To Maintain Power Supply?

‘Peak lopping’ otherwise known as ‘peak shaving’, is the use of an additional power source (such as a generator) in synchronisation with the mains power supply, to deliver enough power to meet the peak demand that cannot be met by the mains supply.

Using a generator to provide a ‘peak lopping’ power supply, will enable the use of the most cost-effective mains power but provide the added support to reinforce the mains power during periods of high demand.

What is an ATS panel? (Automatic Transfer Switch)

ATS panels or automatic transfer switch panels are used in combination with standby generators to automate the switch between the mains power sources and a generator in an outage or blackout.

An ATS panel ensures that you do not have to manually switch to an alternative power supply, such as a backup generator in the event of a power outage. An ATS will automatically switch to another power supply, reducing the risk of data loss, damage to electrical equipment or any disruption to a business or facility. 

The ATS panel monitors the incoming AC mains supply so that should there be a blackout or brownout, the electrical load is transferred to the standby generator, and when the mains power is restored the ATS switch returns the building back to the mains supply, and shuts down the backup generator. 

Using an Automatic Transfer Panel for Safety Reasons

An automatic transfer switch is installed as part of any generator project where there is a mains supply, to not only protect data and electrical equipment but for the safe automatic transfer of electrical load. The fact that this process is completed automatically prevents the risk of human error where the consequences could be fatal.

ATS – Preventing Power Loss

The benefit of an auto system over a manual is the ATS panel moves the electrical load without the input of any manual process, saving any issues with loss of power. The automated transfer switch and associated control system senses the mains supply issue and starts the backup generator, in the event of a failure.

Without ATS panels, organisations would have to manually change over from mains to the generator and therefore suffer a longer break in the electricity supply. They would also be reliant on having the correct engineer available to carry out this task.

ATS Panel Pros

While a manual panel might be a cheaper option, there is no doubt that the pros of choosing an ATS outweigh the cons.

  • Avoid the hassle of switching the system on when the mains fails and you need the generator
  • Avoid having to manually start the generator
  • Nobody has to be stationed nearby to start the generator when there is a blackout
  • Enjoy the automatic restoration of power in a number of seconds!
  • Protect essential electrical hardware that needs a continuous power supply and is reliant on a backup generator.

ATS Panel Manufacturers

Shenton Group designs and manufacturers ATS panels, ensuring that the continuous power solutions we provide operate superfluously, linking ATS, UPS and standby generators.

Aside from turnkey generator solutions, which may include elements such as ATS panels, switchgear and of course, automatic transfer switches, Shenton Group offer remote monitoring systems and ongoing maintenance plans. This means you can operate safe in the knowledge that your backup generator and associated equipment is in working order for when you most need it.

If you are wondering what type of ATS panel you require for your application or need assistance in connecting an ATS to your existing setup, why not get in touch and we can properly assess your needs and help you find the perfect solution.

What Is the Difference Between ATS and AMF Panels?

Automatic Transfer Switches (ATS) and Automatic Mains Failure (AMF) panels both switch an electrical load from normal supply to a standby generator supply, and back to the mains when required and are in effect just different terminology for the same thing.

An ATS Panel Solution for Amazon Distribution Centre

After an initial assessment, Shenton Group provided a 275kVA generator to an Amazon distribution centre and as part of the project, to ensure seamless generator changeover, a 400A ATS (automatic transfer switch).

For more information about any ATS Panel or generator solutions, get in touch with our technical experts today, and we will be happy to provide you with the best course of action for your premises.

National Grid Set to Lose Responsibility of Overseeing UK Electricity & Gas Systems

After 30 years of managing the energy system in England, Scotland and Wales, government ministers are planning to remove the National Grid as the electricity system operator as it looks to meet its 2050 net-zero emissions target.

Management of the UK’s electricity and gas systems, including balancing supply and demand to ensure electricity supply, is set to change hands as part of a revolution of our electricity network, driven by smart digital technology.

The responsibilities of preventing blackouts and keeping the power on are set to be given to an independent body, following recommendations from Ofgem earlier this year. The government’s business department is looking to create an impartial organisation separate from the FTSE 100 utility, as part of plans that could save £10bn a year by 2050 and create 10,000 jobs for electricians, data scientists and engineers.

Better Value for Bill Payers?

UK energy system set for management shakeup Shenton Group

Aside from looking to help the country meet their 2050 net-zero emission target, ministers are taking up the advice of Ofgem that a new independent body overseeing the electricity system would deliver better value for bill payers, as well as more effectively deliver the changes required to meet the 2050 targets.

Speaking to The Guardian, Anne-Marie Trevelyan, the energy and climate change minister, said the rules would allow households to “take control of their energy use and save money” while helping to make sure there is clean electricity available “when and where it’s needed”.

Electricity demand is on the rise with the uptake of electric cars on the rise, while many new homes and existing homeowners turn to low carbon heating, such as electric heat pumps.

As reported in the Financial Times, ‘the government said it was important to reassess the “governing institutions” that underpin the country’s energy system as it “undergoes a transformation equal to any it has undergone in the past” as Britain switches away from polluting fossil-fuel power stations to rely on more weather-dependent renewables such as wind and solar.’

Time for Change

In recent years, the National Grid’s role in electricity and gas infrastructure has come under government scrutiny given a conflict of interest over their ownership of electricity and gas infrastructure throughout the UK, and their work with subsea cables that trade electricity with France, Belgium and the Netherlands. Furthermore, ministers have already questioned the organisations’ involvement in overseeing the energy system, ever since the power cut that affected 1 million homes in England and Wales back in 2019.  

The National Grid’s electricity systems operation has previously been valued at £300m by Barclays.

Greener Energy Supply

UK energy system set for management shakeup Shenton Group

There is a string of new proposals currently being mooted to help connect the millions of electric vehicles that will be on UK roads in the future, with new regulations being suggested that aim to make it easy for electric cars to export electricity from their batteries back to the power grid or to property. As reported in The Guardian, the idea behind this is to ‘help large-scale and long-duration batteries play a role in storing renewable energy so that it is available when solar and wind power generation levels are low.’

As technology evolves, the government is looking to ensure our energy systems can cope with the demands of the future. Jonathan Brearley, Ofgem’s Chief Executive has said that the UK requires a ‘revolution’ in how we use electricity and that a new digital energy system is ‘essential’.

Electrical Systems: What is a Brownout?

Generally speaking, electricity supply exceeds demands, but when there is any disruption at power plants or the supply source it can lead to brownouts. With the installation of a UPS and backup generator, it is possible to avoid fluctuation issues such as brownouts or power surge and remove the reliance on electricity provided by the grid.

What is a Brownout?

A brownout occurs when the voltage dips below the usual mains supply level and can last from a few seconds to hours or even days. When the weather conditions worsen or there is a growth in power demands, the additional strain on the electricity network may result in a brownout. Intentional brownouts take place too, controlled by the National Grid when they are looking to ration supplies and prevent a possible blackout. The term brownout stems from incandescent lighting dimming as the voltage is reduced.

Brownout Indicators

Voltage reduction is often imposed to reduce load and prevent a power outage, with common signs of an electrical system brownout including:

  • Flickering lights
  • Electrical appliances switching off & on again
  • Intermittent internet connections
  • Disruption to air conditioning
  • Security system outage

What Causes a Brownout?

The demand for electricity is continuously fluctuating with power companies using their networks of generators, sub-stations and transformers to deliver electricity to their customers. Our power consumption as a nation varies and so the National Grid has a constant balancing act on its hands, sometimes leading to an unplanned outage, leaving affected homes and businesses without power.

The National Grid has previously shown strain due to power demand, with at least four market warning notices issued last winter, as seen in a report published in Bloomberg.

When the demand pushes the energy provider to capacity, the solution is to put an intentional limit on the flow of electricity, meaning the power continues to remain on but at lower voltage levels until the demand reduces. Brownouts can also occur as a result of damage or malfunction within the grid or at the power source. This is not ideal for businesses, healthcare facilities, finance companies or server locations that rely on continuous power. Fluctuations in power can cause equipment to malfunction. Loss of power to industries such as these can have disastrous effects on security, reputation and could be life-threatening.

Brownouts and Power Outages Caused by Weather


Planned outages are a lot easier for businesses and organisations to handle than an unforeseen dip or cut in electric power due to bad weather. In adverse weather conditions, there can be a huge surge in demand for power to keep homes warm and the lights on, and the power companies have to enforce brownouts to balance supply and prevent blackouts.

Equally, at the height of summer, air conditioning usage can shoot up causing a spike in the demand for power and energy providers may enforce voltage reductions until reserves are restored.

What’s the Difference Between a Brownout and Blackout?

Blackouts are when the power switches off completely, rather than a temporary reduction in voltage. 

Power cuts or blackouts are however often less damaging and disruptive than a brownout, because when devices continue to receive power at lower levels, some may malfunction. A reduced level of electric current may leave electronic devices like consoles, computers or televisions permanently damaged by fluctuations in electricity levels.

In the IT sector, it is paramount to protect IT loads and as such, a UPS and backup power supply are an ideal solution to bear the load should there be any issues with the National Grid. Uninterruptable power supplies (UPS) maintain the correct level of voltage when there are dips. In a brown out a UPS will take over and will ensure that your equipment has the required voltage to fully operate and will protect it from any disturbances, before potentially handing over the task to a generator.

Too much electrical load can also cause equipment to malfunction. A UPS also act as a surge protector for electronic equipment.

Put a Stop to Power Failure

Working with a huge variety of clients, the team at Shenton Group are well equipped to protect you from any power interruption. We assess your demands and put forward a plan so that in any outage, grid malfunction or temporary brownout scenario, is managed and your power supply protected. With uninterruptible power supply options available to monitor the electrical power, it is possible to prevent a surge or brownout and keep the lights, equipment and security measures on.

Shenton Group is the UK’s leading technical expert in standby power, uninterruptible power supplies, and combined heat and power, and we keep the power on and businesses operating.

Dealing With an Electricity Power Cut

Most power cuts are unforeseen and until the electricity is cut off, many organisations do not appreciate the importance of electrical power. The vast majority of the time, power outages are a result of inclement weather such as a lightning strike damaging power lines, but there are countless other reasons why they occur. In these circumstances, it is important to have a plan in place to restore the power quickly.    

Power outages may be long or short term, therefore a process for when the electricity is cut off should involve a backup power source, especially for organisations reliant on continuous power.

Hiring a Generator in an Emergency

In the event of electricity power cut, a professional team such as Shenton Group will deliver a power solution to provide you with temporary power. Hiring a generator is a cost effective option for those who do not want the bigger outlay of purchasing one.

If you are planning to find a generator hire company to support you in the event of an electricity power cut, choose one who provides generator hire 24/7 and is available every day of the year. Unexpected power cuts are exactly that and can occur at any given moment, which means generator rental providers need to offer support around the clock.

Power Call – Nationwide Emergency Call out Generators

When your electricity is cut off, there is an option available without the outlay of a permanent on-site generator. With strategically placed depots throughout the country, a fast response time to a UK power cut is guaranteed with our Power Call service. Power Call is a unique service to Shenton Group customers that ensures you are not left without power for long periods of time, available for a small monthly fee.  

How Does It Work?

  • Once registered, a Shenton Group engineer will come to your site or facility and install a ‘plug-and-play’ manual generator connection and changeover system. This enables the generator to be quickly and easily set up once on site, providing power until the mains power returns.
  • For a fixed monthly fee, emergency call outs to unscheduled power cuts are unlimited.
  • A network control room manages all call-outs around the clock, co-ordinating delivery, connection, refuelling and the collection of the generator.

Power Call provides customers with support during an electricity power cut, equipping them with everything they need to remain operational but without breaking the bank.

Turnkey Temporary Power Solutions

When you need to act quickly to restore the power, having access to a turnkey solution is essential. Our dedicated team of specialists will be able to establish the exact solution required for your site. Better still, given their experience, the team will also recommend and provide all the temporary power equipment required including:

  • Transformers
  • Cables
  • Cable Protectors
  • Load banks
  • Fuel tanks
  • AMF

Temporary power solutions such as generators are classed according to kVA (Kilovolt-ampere). This is essentially an indication of the power output. 1 kVA will provide 1,000 volt-amps. At Shenton we provide the hire of standby and prime power generators from 30kVA up to 1250kVA, and can synchronise multiple generators for larger power requirements. This enables us to supply our clients with a suitably sized generator for their needs.

We are equipped to meet the demand of any bespoke residential, commercial, or heavy-duty applications 24/7, 365 days a year UK wide.

Regardless of where you are located in the UK, no matter how remote, we will deliver everything to your site and set it all up allowing you to focus on running your business.

Protection from Electricity Power Cuts

Aside from temporary backup power solutions, there is the option to install a permanent backup power supply, and for those who cannot afford any loss of power, UPS solutions. A UPS will help to protect expensive or essential equipment from losing power, acting as a bridge and providing valuable power whilst your generator starts up. Once the generator is up and running, the full electrical load is then switched to the generator. UPS solutions also offer the added bonus of stabilising the power supply, stopping power surges or spikes which can cause damage to equipment.

For those looking for a diesel standby generator, we are able to offer assistance for the full turnkey installation including:

  • Design
  • Manufacture
  • Project Management
  • Installation
  • Testing

We now also offer finance for UPS and generator installations, for those looking to have a generator on site to protect their assets from power cuts.
