Categories: Diesel Generators, Generator Rental, News, Products

Any hardware device that provides electricity to one or more electric devices is referred to as a power supply. Power supplies mostly fall under the categories of voltage sources and current sources. However, there are also current sources that provide constant current. Often, the term “power supply” refers to a voltage source.

Constant-voltage power supplies and constant-current power supplies are two broad categories of power supply circuits, but what do constant current and constant voltage mean, and are they the same thing? This blog will detail what these two phrases mean, the differences between them, and what applications they are used in.

Constant Current & Constant Voltage

Constant current and constant voltage may sound similar, but they are actually two very different things. Each of these power supplies has different applications, so choosing the right power supply depends on what you need. Let’s break down what they both mean and how they work.

What Does Constant Current Mean?

A constant current (CC), also known as a steady current or stationary current, is a type of DC (Direct Current) that doesn’t change its intensity over time and maintains it.

A constant current source will be used if an electrical load is varied, as it can help stabilise the load into a steady current. A CC power source will maintain a current at a relatively constant level, regardless of any large changes in voltage supply.

An application that uses constant current power supplies is LEDs. While a high series resistance is enough to light an LED, the design may sometimes need to guard against high current, or you can risk burning out and short circuiting the LEDs.

What Does Constant Voltage Mean?

Constant voltage is the opposite. CV refers to a power supply that controls the output voltage to a constant level. This type of power supply always provides constant voltage regardless of the electrical load.

This type of power source is widely used in power supplies for electronic circuits and most DC benchtop power supplies are normally operated in constant voltage (CV) mode.

Some common constant voltage sources are batteries and regulated power supplies. Though batteries can’t supply constant voltage indefinitely and require charging or replacing.

A constant voltage is usually used on circuits that require a steady voltage supply for efficient operation. A good example would be paralleled LED strip lights which require a constant voltage LED driver to produce the most balanced current over the independent output channels.

What are Variable Power Supplies?

Variable power supplies are usually an adjustable component or device, which includes a means for the user to easily vary and adjust the output voltage and sometimes the output current. This can be through a control panel to adjust the setting and switch between CC and CV modes. The original power source’s voltage that is sent to the circuit is limited or increased by a variable power supply. For example, if you run a model train, you would flip a switch and deliver a voltage in increments to increase the speed of the train and reduce the voltage supply to slow it down. This variable type of power supply is also used in tattoo machines and larger industrial power supplies, such as back up generators.

Automatic mains failure (AMF) panels, often referred to as automatic transfer switch (ATS) panels, make the power switch to emergency standby generators in the event of a significant loss of mains power or total blackout. Without AMF panels, generators need to be operated manually and that can mean lost data, potential damage to electrical equipment, and huge amounts of disruption.

Most power cuts are unforeseen inconveniences, and until the electricity is cut off, many organisations do not appreciate the importance of electrical power to their operations.  

In the UK, power outages are usually the result of inclement weather, such as power line damage caused by direct lightning strikes, but there are countless other reasons why they may occur, including planned power cuts to conserve energy resources during an energy crisis.

In these circumstances, it is essential to have a plan in place to restore power quickly, as any company without an external backup power source can experience downtime in the event of a power cut. Losing customers, revenue, and damage to machinery and equipment are all preventable with adequate power prevision planning.

Effects of Power Outages on Businesses and Organisations

Loss of power can be detrimental to any business or organisation, causing data loss, damage to sensitive electrical equipment, loss of revenue and missed deadlines amongst the immediate impact of loss of lighting, air conditioning and other necessities.

Whether the outages are short or long-term, a process for electrical power cuts should be implemented to mitigate any damage, including the reservation of a backup power source, such as a fuel-based generator. You may also choose to employ a battery-powered backup system, such as a UPS (Uninterruptible Power Supply). These UPS units are crucial to your backup power source plan, particularly for organisations reliant on a continuous, stable power supply, such as hospitals and data centres.

UPS devices provide a temporary battery output, allowing generators to start up before they take on the full electrical demand (known as the load) during an outage. The relay between the UPS unit and generator makes for a seamless transition between the mains and backup power source, mitigating risk and damage to people and machinery. At Shenton Group, we provide a full range of backup and mains power solutions and services for businesses for your peace of mind.

Hiring a Generator in an Emergency

In the event of an electrical power cut or surge, Shenton Group are able to deliver a power solution that’s right for your needs, such as diesel generators, fuel tanks, and battery-powered UPS devices to give you a temporary backup power external to your mains. Generator hire is a cost-effective option for organisations that require a temporary solution and do not want or need the bigger outlay of purchasing a permanent backup power solution.

If you are in need of a generator hire company to support you in the event of an electricity power cut, we recommend choosing one that provides generator hire 24/7 and is available every day of the year. Unexpected power cuts are exactly that; unexpected, occurring at any given moment. To lessen the effect of an electrical power cut on your operations, your generator rental provider needs to offer support and maintenance around the clock..

How Do Generators Work? A Simple Guide from the Experts

Categories: Diesel Generators, Emergency Power: Power Call, Generator Rental, News

Generators are an essential asset in maintaining a stable power connection to your business and residential properties. Often hailed as a lifeline, they provide crucial support in case of a mass blackout or power loss.

In this article, we will provide a basic guide on how generators work, explain the different types of generators, and how you can ensure you find the right generator for you and your needs. Firstly, let’s look at what generators are:

What are Generators and What Do They Do?

If your mains power supply goes down, diesel generators are the perfect solution to supply power when it is needed, but they can also be used as a permanent power solution. Generators are complex machines that work by converting mechanical or chemical energy into electricity by capturing kinetic energy (the power of motion) and turning it into energy.

Industrial generators can be used as a primary power source in places where the local electrical grid is unavailable or difficult to access, such as mining and farming operations, new developments, and remote locations. These industrial generators are also frequently used to supply backup power to buildings, businesses, or homes during power outages. Generators can also be temporary, portable power solutions or permanent installations.

Shenton group typically supply diesel engine generator systems as standard. The UK has a very well-developed power grid, which remains stable for much of the time therefore most of the generator installations in the UK are for standby use or for legislative purposes such as life safety applications. Diesel generators are ultimately the most cost-efficient and beneficial solution for emergency standby power. The plethora of reasons why diesel generators are required include equipment malfunction, switchboard failure, transformers failure, network faults, transmission distribution faults on the network as well as to support renewable systems.

How Does a Generator Work?

Most generators run on some form of fossil or gas-based fuel, such as diesel, petrol or natural gas. The internal combustion engine will then run on the provided fuel source and in the process spin an alternator which creates electricity.

The Different Components of A Generator

There are many components that help make up a generator.

Below, we have listed the different components that make up a generator and what their function is:

Diagram of a generator with all the parts labelled
  • Engine– the engine is the main component of a generator and as it runs it rotates the alternator rotor.
  • Radiator: The radiator is used to cool the engine as it runs and keeps it from overheating
  • Exhaust: A generator set includes an exhaust system that collects hot gases from engine cylinders and discharges them as quickly and silently as possible. 
  • Alternator: The main function of an alternator is to convert mechanical power to electrical power. Alternators consist of a steel housing containing the main stator and the rotor assembly. In a process called magnetic induction, the engine rotates an electromagnet rotor, inside the stator to produce an electrical current through copper wirings. Essentially, the engine drives the rotating shaft and turns the rotor which then produces electricity.
  • Control Panel: In layman’s terms the control panel is the brains of the generator. There are various types of control systems but in a gist, they enable effective monitoring, and control and provide diagnostics to ensure the generator set operates within safe parameters.
  • Output Breaker: this is the main switch where the power coming from the alternator can be connected to and provides protection against overload and electrical faults.

Generator Ratings

Specifying a generator can be a daunting task as it involves multiple points of consideration to be able to select the correct solution. There are three main types of generator ratings that are commonly referred to and these are explained below:

  • PRP or Prime Rated Power
  • COP or Continuous Rated Power
  • ESP or Emergency Standby Power
A generator in use to show examples of different generator types

Prime Power Generators (Prime Rated Power)

Prime Power generators are commonly used as the main source of power on building sites and events but also in the life safety, industrial and construction industries. Sites where a reliable main power source is needed external from the mains or National Grid, would also benefit from having a Prime rated generator access. Average power output should be 70% of the prime rating over 24hr period with unlimited allowance on hours of use. In times of peak demand, the generator would work on 100% of prime kW rating with 10% overload capacity for emergency use for a max of 1hr in every 12 hrs of use.

Prime power generators are the preferable option in the UK for continuous use over other types of generator, especially when the load (demand for power) varies or overloading may occur. They provide a buffer for design teams because of the 10% overload capacity and the unlimited use capability.

Continuous Power Generators (Continuous Rated Power)

Although very similar to their prime power counterparts, these generators are designed to run continuously with 100% consistent load for unlimited hours. These generators are mainly used for remote projects off the main power grid, including mining, construction, and oil or gas works.

Standby Generators (Emergency Standby Power)

Standby generators are designed to support mains power in the event of an emergency, providing power to buildings or anywhere needing a backup power supply, such as hospitals and data centres. ESP rating is available for the duration of the emergency outage. The average power output should be around 70% of the standby power rating. It’s a rating based on a varying load with the limitation being 200 hr annually. Having a backup generator for your company means you are protected in case of a blackout. To ensure a fast response to an outage, a standby generator will run weekly self-tests to ensure it can respond quickly and run efficiently the next time it is needed.

How to Determine the Size Requirement of the Generator Set Properly?

Like the main utility supply, generators are not an unlimited source of power therefore loads need to be steadily applied to prevent an engine from shutting down. When the load is suddenly applied, there will be a transient deviation in the voltage and frequency. Smaller generators, below 100kva, tend to have a greater load acceptance capability. When applying or removing a load from a generator set, it has an impact on the quality of power being delivered. The extent of the impact would depend on a variety of factors however the most significant factor is the size of the load that is applied to the generator at any given time. Shenton group has the extensive technical capability within our highly experienced team to accurately advise our customers on the best generator set suitable to their unique circumstances.

Next, we explore the function that an ATS provides and how they interact with a generator.

Do I Need an Automatic Transfer Switch (ATS)?

Not necessarily, however, if you are using alternative sources of power, an ATS will automatically switch over from the main power source, reducing the need for manual switching between power supplies. An Automatic Transfer Switch provides a reliable means of automatically transferring load between the primary and alternative sources of electrical power, such as transferring from mains power to a generator.

Your power sources are continuously monitored by an automatic transfer switch. You won’t need to manually start the standby generator with an ATS, as it will start and stop as needed during a power loss. Using your generator becomes simpler as a result.

Within seconds of a power outage, an automatic transfer switch senses the loss of power, instructing the generator to start before transferring the electrical load to the generator to provide backup power. Once the main utility power returns, the ATS system transfers the electrical load back to the grid or main power source and signals the standby generator to shut down. The generator then returns to standby mode where it waits for the next outage.

Like the main utility supply, generators are not an unlimited source of power therefore loads need to be steadily applied to prevent an engine from shutting down. When the load is suddenly applied, there will be a transient deviation in the voltage and frequency. Smaller generators, below 100kva, tend to have a greater load acceptance capability.

Generator Rental, Purchasing & Maintenance

Whether you’re running a data centre, bank or hospital, power failures can be disastrous to your essential operations. Having a standby generator reduces the risk of power interruption, however, they will only be useful if they’re properly chosen, installed, and maintained.

At Shenton Group, we can provide services including generator hire, maintenance, installation, and servicing for combined heat and power solutions. If you’re thinking about renting or trialling a generator, please visit our generator rental section.  If you need assistance in choosing and purchasing the right system for you, our power consultants can help.

What Is an Uninterruptible Power Supply System?

Categories: News, Power Systems (Generators and UPS)

With the recent news regarding the potential blackouts this winter, organising backup power for your business is vital. 

Any downtime caused by power outages can be financially crippling for a business or organisation. The average power cut in the UK lasts for 50 minutes. This may not sound too long, but with one hour of downtime estimated to cost a small business around £800, it can be very damaging.

Understandably, bigger organisations and companies can see higher losses from a power cut, but it is also expected that they can recover quicker too. Google lost power back in 2013, and it experienced losses of £100,000 per minute. To avoid loss of output for your business, investing in a backup solution which includes a UPS System is a good idea. But what is a UPS system?

An uninterruptible power supply (UPS) offers a continuous power supply and ensures there is no break in power when the main power source fails, or if the voltage drops to an insufficient level or surges and causes an outage.

In the event of a power outage, a UPS can provide power for a couple of minutes and up to 2 hours depending on the battery size and the electrical load it needs to support. This allows equipment to be shut down properly and safely and/or provides time for the standby generator to start up before taking the full electrical load.

UPS Power Protection for your business

From small businesses to large scale operations, uninterrupted power supplies can serve an important purpose. Power cuts can cause major issues for your equipment and productivity, but a UPS is like an insurance policy against this, keeping you online and connected, giving you time to respond to the issue before the lights go out.

To avoid the detrimental impact it can have on your business, safeguarding against outage issues with an uninterruptible power supply makes commercial sense, especially when used in tandem with a backup generator. A UPS is just one part of a reliable backup power solution. A UPS will provide a continuous power supply for a short amount of time and can bridge the gap whilst the generator starts up. Once the generator is ready and can take the full electrical load, the generator will be able to provide power for 72 hours or more.

For some businesses having 15 mins to 2 hours of UPS backup power is sufficient, however for businesses that cannot afford down time, a generator is a viable option. Click here to see more information on the difference between generators and UPS.

Uses of an Uninterruptible Power Supply

Uninterruptible power supplies are deployed for use in a wide number of industries where a drop in power supply is not an option.

Manufacturing and production lines require power around the clock to ensure machinery can keep operating. Industrial UPS can be used at plants and factories to ensure normal operations can continue to take place with little-to-no interruption in the event of a power outage.

UPSs are also vital in the medical sector, where lab facilities cannot afford power outages and the effects on key devices used in patient care, including life support systems, could be life threatening.

In the modern world, Datacentres need consistent power as a power outage can lead to system malfunctions and could mean security risks. Telecommunications & Computer Systems are crucial, and they are heavily reliant on continuous power supply, so UPS plays a key role in their operation, keeping servers running and computers switched on.

Any organisation that needs a constant flow of high-quality electricity to keep the lights on, IT systems and electrical equipment operational, would rely on a UPS to prevent the severe consequences that can be caused by a blackout. The list of applications that UPS can be used in goes on, and examples can be found in almost any industry you can think of.

Three types of UPS systems

Standby

The simplest and most affordable UPS system is Standby, or offline. Standby UPS power supply is generally used for basic electronic equipment such as consumer electronics and security systems, ideal for use in a small office or at home and provides a power supply of up to 3kVA.

Standby UPS systems make use of stored battery backup power during an outage, or when the voltage levels dip or surge. Considered an entry-level UPS, standby systems will protect you and your equipment giving you that imperative battery backup.

Line-interactive UPS

Line-interactive UPSs protect you both on and offline. This type of uninterruptible power supply can correct power without switching to battery-based reserves.  A Line-interactive UPS contains an auto transformer that regulates any over or under voltage. It can be used for consumer electronics, network equipment and entry-level servers.

This type of UPS is interactive as it automatically selects different power taps on the auto transformer and can maximise any limited battery backup reserves by correcting any power fluctuations and managing current levels in an outage or power surge.

On-Line Uninterrupted Power Supply

Online UPS are generally more expensive due to the equipment involved but offer a premium solution for critical electrical equipment and acts as an ‘electrical firewall’. It not only can protect you against a power outage but regulates the level of power delivered to your equipment.

uninterruptible power supply

Online uninterrupted power supplies provide consistent power converting AC power to DC, and then back to AC with zero transfer time using double conversion UPS system technology. It is ideal for the protection of essential IT and server equipment, data centres, telecoms systems and top-end electrical equipment. If a power loss happens to take place, the batteries, which are always connected to the inverter, keep the power supply consistent and cause no interruption at all.

Uninterrupted Power Supplies protect your Electrical Equipment.

UPS systems will look after you and your equipment, so when your power runs out, you can continue to operate but they also ensure you are protected against;

UPS systems will ensure that if there is a power outage, you are protected against:

  • Power Failure. A UPS can ensure there is constant power to your all-important electrical equipment so it can continue to run preventing any downtime or data loss for anywhere up to 2 hours.
  • Under Voltage. Uninterrupted power supplies ensure that your IT systems or electronic devices continue to receive the correct amount of voltage, and IT hardware remains switched on even when the power supplied from the mains is insufficient.
  • Power Surges. Prevent electrical equipment from any damage during power surges caused by high voltage levels, which then suddenly drop off.
  • Lightning or Power Supply Malfunction. Lightning and supply malfunctions can cause energy bursts and a spike in voltage, which can cause the overheating of your equipment; something that a UPS can prevent.

UPS Maintenance Contracts & Servicing

It is essential to maintain uninterrupted power supplies on a regular basis, as the core components can deteriorate with age. At Shenton Group we review organisations’ power demands and design backup power solutions suited to your unique needs.

The key part of a UPS is the batteries. However, they are consumable components as are other parts such as cooling fans, which can also suffer from wear and tear, so a regular health check is vital to prevent you from ever becoming unstuck at a time when you most need an uninterrupted power supply.

Shenton Group offers a range of UPS Maintenance plans based on your individual requirements so that your equipment can remain in shipshape. Speak to us about an uninterruptible power supply today.

Electricity Consumption Statistics for 2022, and a Forecast of the Electricity Market for 2023

14 December 2022

No comments
Categories: Industry, News

Introduction

2022 has been a turbulent year for energy. According to a report by IEA, in the first half of 2022 gas prices in Europe increased fourfold and coal more than threefold from the same period in 2021. This resulted in wholesale electricity prices more than tripling in many markets, including the UK electricity market which sources its electricity supply from large coal and gas power stations. The following blog will detail the electricity consumption statistics for the first two quarters of 2022, breaking it down by sector. We will also detail a predicted forecast of the electricity market in 2023.

2022 Electricity Consumption Statistics

The electricity consumption data below is from a report looking at UK April to June 2022 energy consumption, provided by the Department for Business, Energy and Industrial Strategy.

Domestic Electricity Consumption

The consumption of electricity from the domestic sector decreased substantially in Quarter 2 of 2022, decreased from 15.8 per cent to 21.7 TWh, the lowest value since Quarter 3 in 2019. This decrease reflects the ease of COVID-19 restrictions in place during the same months in 2021, which meant that people spent less time at home and were comparatively using less electricity. 2022 also saw warmer temperatures in April and May, which reduced the electricity demand for heating. This decrease in 2022 may also reflect customers’ efforts to reduce consumption because of the soaring electricity prices.

Non-Domestic Electricity Consumption

Both non-domestic sectors saw a slight increase in consumption levels in Quarter 2 2022 compared to the same period in 2021. The lifting of COVID-19 restrictions meant that businesses and industries could return to normal operations during this period, however the increase in demand was partially offset by the warmer than average temperatures.

The industrial sector consumed 0.8 percent more electricity compared to Quarter 2 2021 and comparably, the consumption by the other final users, including the commercial sector, increased by 0.6 per cent in Quarter 2 2022 compared to the same 2021 period.

Total Electricity Consumption

The total consumption seen by Quarter 2 of 2022 increased by 8.2 percent compared to the same period in 2021, in contrast to a 5.5 percent decrease in total demand. This resulted from the UK becoming a net exporter of electricity in Quarter 2, with net exports of 4.0 TWh.

Electricity power box with rain and electricity warning label

What does all this mean?

In 2022, the UK saw rising costs of energy combined with warmer-than-average temperatures, resulting in a decrease in domestic energy consumption. On the other hand, the UK saw business re-open fully after COVID-19 in 2022, which alongside the UK becoming a net exporter of electricity, resulted in an increase of total energy consumption.

This overall increase in consumption is one reason why regions across the UK have been warned about potential blackouts or power cuts in the 2022/23 winter season, as the National Grid may struggle to meet energy demands.  

Electricity Market Forecast for 2023

With the ongoing conflict with Russia and Ukraine, Europe is preparing to reduce its reliance on Russian fossil fuel imports by hastening its clean energy transition heading into the new year. The continued energy price crisis is fuelling debate on wholesale electricity market design, while governments are trying to cushion high electricity prices with diverse support schemes.

The Economist Intelligence Unit or EIU have predicted in their Energy Outlook 2023 report that global energy consumption will increase by only 1.3% in 2023 amid a slowing economy. Despite decarbonisation targets, coal consumption could grow marginally to compensate for gaps in gas supplies, and more extreme weather events could force many countries to fall back on fossil fuels, delaying the energy transition.

However, EIU also predicted that renewable energy consumption will surge by about 11% and the energy crisis will prompt some governments to backtrack on efforts to phase out the use of nuclear power.

There are large uncertainties about electricity in 2023. The International Energy Agency’s report detail that the main uncertainties affecting this forecast for electricity demand are primarily related to fossil fuel prices and potential economic growth. As of mid-2022, the global electricity demand growth in 2023 is expected to remain on a similar direction as this year. Strong renewable energy growth of 8% and recovering nuclear generation could also displace some gas and coal power, resulting in the electricity sector’s CO2 emissions declining by around 1%.

Conclusion

With the National Grid’s warning about potential power cuts this winter, many homes and businesses are worried about losing power, as well as the financial impact of rising gas and electricity prices heading into the new year. The recent cold snap this month has already started to test the UK’s efforts to prevent winter power cuts, and many are looking for ways to cut energy costs. The National Grid are providing an Off Peak Energy rebate Scheme from November to March to help prevent power outages and ensure energy sustainability while helping homes and businesses save money.

Your business shouldn’t be left in the dark this winter! We have provided reliable backup power solutions to a variety of sectors across the UK. Shenton Group designs, supplies, installs and maintains reliable backup power solutions, and offers 360 degree support.

Save Money on Energy Bills: Off Peak Energy Rebate Scheme from National Grid

11 November 2022
Shenton
No comments
Categories: Industry, News

Back in October, the National Grid warned that businesses and households in the UK could experience three-hour power cuts this winter due to the energy crisis and gas shortages. These strategic cuts would be an ‘unlikely’ scenario but would be carried out at peak times in the morning, or more likely between 4pm and 9pm in an effort to reduce the total energy consumption by around 5%.

In response to this, the National Grid launched a new off peak energy rebate scheme, Demand Flexibility Scheme, at the start of this month in response to the risk of blackouts this winter and the energy crisis. This scheme can help reduce energy consumption over peak times when the demand for energy is high, but how does it work and how much money could eligible homes and businesses save on bills if they sign up?

How Does the Demand Flexibility Scheme Work? 

This scheme is set to run from November to March 2023 and works by predicting when there will be a shortfall of energy. Participating energy suppliers will get 24 hours’ notice of a predicted shortfall and will then ask customers to curb their energy use at a certain time.

One way to lower your energy consumption is to avoid using appliances and products that use a lot of power, for example running dishwashers and tumble dryers earlier or later in the day or if you have an electric car, charging it outside the peak times.

Electric car plugged in and being charged off peak

You won’t need to switch off your heating or lighting and you can still use your oven to cook food but reducing your overall energy use wherever possible will help save power and will shave money off your bills in the long run.

Who is Eligible for the Scheme?

Currently, this scheme is being rolled out and implemented by energy suppliers and will be monitored using a smart meter, so only customers with smart meters will be able to take part in the scheme. Find out more about the suppliers that are known to be running the scheme and how much you could save on bills below.

More than 3.5 million of its customers should be qualified, but the firm hasn’t provided any information on how to apply or how much you could be eligible to receive back. Please keep a watch on your emails and the British Gas website as registration should be up soon.

Ovo Energy

Ovo Energy, which is running its own trial version of the scheme, said that a typical household uses a fifth of their daily energy between 4pm and 7pm and customers could make a saving of up to £100 if they signed up to use energy at greener times of the day. Sadly, this version of the scheme isn’t a part of the Demand Flexibility Scheme and only 5,000 OVO customers will be able to participate in the trial. Those able to sign up will be informed by the company.

Octopus Energy Saving Sessions

According to the business, all Octopus smart meter users (about 1.4 million consumers) are eligible and can earn up to £100 in total by saving £4 per kWh compared to their average usage. Users are able to sign up on the energy supplier’s website.

Both E. On and EDF haven’t announced details of their schemes yet but have said they will run them. If you are interested in learning more about the scheme and your eligibility, it is best to check with your energy provider and their website for further updates.

Preparing for Potential Blackouts

The National Grid anticipates that this plan will prevent the need for blackout warnings this winter by reducing demand by around two gigawatts, or enough to power about 600,000 homes. However, blackouts could still be a possibility.

If you are worried about power outages affecting your business this winter, we can help. At the Shenton Group, we provide a complete generator rental service to commercial clients. Renting a diesel backup generator is a fantastic choice to explore if your organisation needs to maintain crucial operations, but don’t wait until the last minute.

Three-Hour Power Cuts Possible This Winter says National Grid

The National Grid has warned households and businesses in the UK about the potential three-hour power cuts that could start this Winter due to the energy crisis and gas shortages. But what does this mean for homes and businesses and how can you plan for no power?

The National Grid has warned that British households and businesses could potentially lose power for up to three hours at a time this winter if gas supplies run extremely low.

These cuts are an ‘unlikely’ scenario, but National Grid has added that supply interruptions are a possibility if the energy crisis escalates. This plan would involve cutting off power throughout the country in an effort to reduce the total consumption by 5%. 

Any cuts would occur at peak times, either in the morning or more likely between 4pm and 9pm, though customers would be warned beforehand, should a power cut need to be implemented.

The power outages are expected to be rotated so that not all sections of the country are affected at the same time. However, National Grid expects homes and businesses will face no problems as a ‘base case’.

Three Possible Scenarios this Winter

The National Grid’s primary belief remains that there will be enough energy to provide Britain with electricity levels comparable to recent winters. However, it has highlighted two more concerning possibilities which could occur.

In the first case, the European energy crisis would prevent Britain from importing electricity from France, Belgium, or the Netherlands. However, power will continue to flow from Norway.

The National Grid cautioned that, without any action, this situation could lead to electricity shortages. They did, however, state that they had reached agreements with three power firms – EDF, Drax, and Uniper – to keep additional coal-fired power generators on standby in case they were required.

What Does This Mean for Homes and Businesses?

Whilst these power cuts are only a possibility for now, the National Grid will introduce a system on November 1st that will incentivise businesses and the public to limit their electricity consumption at critical peak times during the day.

Households with smart meters could be paid to reduce their usage. For example, by not using their washing machine or oven early in the evening, households could receive up to £10 per day.

Larger enterprises could be compensated for reducing demand, such as altering their energy use periods or switching to batteries or generators during peak times.

The National Grid believe that with these procedures in place, supply disruptions will be averted. However, they stated that they had created a second, more extreme scenario in which Europe’s energy crisis worsens, resulting in a lack of gas in the UK.

In such cases, distributors would be required to switch off energy to homes and businesses for up to three hours during the day, according to the report. The legislation, which has not been used since the 1970s, would require the agreement of both the administration and the King.

“In the unlikely event we were in this situation, it would mean that some customers could be without power for pre-defined periods during a day – generally this is assumed to be for three-hour blocks,” said National Grid.

The number of people without power will be determined by how many power stations are forced to close due to a gas shortage, according to the report.

The cuts would not affect hospitals or ‘priority businesses’. The Energy Networks Association, on the other hand, stated that vulnerable individuals would not necessarily be safeguarded.

National Grid stated that the industry would collaborate with the government to educate the public about such measures, including through Covid-style press briefings.

Shenton Group Complete Generator Installation at London Data Centre

Categories: Diesel Generators, News, Power Systems (Generators and UPS)

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 for Server Room

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.

Request a Site Survey

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
  • Ongoing Maintenance

We provide you with peace of mind that you can operate with confidence that your generator installation will provide the support you need at those crucial times.

Shenton Group is a leading generator manufacturer focused on keeping power supplies operational in the event of a mains failure and improving the sustainability of your power supply.
