Micro Combined Heat and Power Brings Cost and Carbon Savings

Across the UK many establishments have turned to Combined Heat and Power (CHP) to reduce the amount they pay out on heating and electricity, including Imperial College London, who have two combined heat and power systems. These Micro-CHPs have delivered the College significant cost reductions and decarbonisation benefits over the years.

How to Choose a Temporary Power Generator Provider

In times of need, being able to call upon a power generator rental service is hugely important to many industries, allowing them to work in the knowledge that should the power supply cut off; there is a backup plan and they will still be able to function. However, when looking into a power generator rental supplier, what should you consider?

24/7 Generator Support

A power outage may occur at any given moment, including late at night, over the weekend or during the festive period. In fact, during the Christmas holidays, there is often more power used than at any other time of the year. For those who need access to temporary backup power urgently, you must choose a provider who is on hand to assist 24 hours a day, 7 days a week.

Access to a helpful account manager and skilled engineers is pivotal, as you won’t want to be waiting an entire weekend for power to be restored. For those reliant on an electricity supply, be certain that help is always available.

Rapid Emergency Response Times

Aside from having someone to take your call in the UK at any time of day or night, emergency power generators need to be on site quickly. For instance, if a care home loses power, to ensure residents care is maintained power needs to be restored ASAP. Shenton Group offers an average response time of 100 minutes, for a fixed monthly fee via Power Call. With no call out fees and rapid response, a power generator is only ever a phone call away.

UK Wide Generator Hire Coverage

Great news, you’ve found an emergency power generator provider, not so great – the supplier is at the other end of the country. Customers who rely on power may want/need to find an emergency backup power company with service locations close by.

Shenton Group Locations

Shenton Group is the trusted power generator supplier to a whole host of companies and organisations and provides national support. We have 11 offices and service depots UK wide allowing us to service the whole country with short turnaround time, no matter how remote. Local knowledge helps to ensure that when you need power, our engineers will be with you quickly.

Emergency Backup Power Equipment

It is beneficial for you to choose a power provider that has a range of generators and power equipment. Every site is different and the requirements vary. For example, a building site would likely require temporary generators that remain on site for the lifetime of the project, where as a hospital may only need to rent a temporary generator over a weekend whilst they take their permanently installed generator offline for testing.

Not sure what generator size you need? Our technical experts can help you. A professional outfit will be able to visit your site and assess your requirements if you are in doubt about the equipment needed to support you in an emergency.

From 30kVA up to 1250kVA we provide the rental of standby or prime power generators and are able to synchronise multiple generators for larger power requirements. The backup power supply may even form just a small part of the overall solution with cable, fuel tanks, AMF panels, distribution panels, security locks and refuelling all available as part of the package at Shenton Group. This is why it is good to speak to the experts to ensure you get the solution you need.

Maintenance of Temporary Power Generators

A rental generator might be required for months on end or even years. Whether its running around the clock providing prime power or in reserve as backup power, it will require maintenance to ensure it remains reliable and works efficiently.

Find a power generator supplier who provides a complete ‘Baby Sitting’ service for your rental generator. For critical sites this option is very appealing. Our engineers are available to be on site throughout the duration of the rental to ensure should anything go wrong, that help is on hand.

Emergency Backup Generator

Do Your Research

If you are responsible for sourcing a temporary electricity supply, then choosing the right company is essential. At Shenton Group, we have been in the industry since the 1980s. Our heritage and expertise stand us out from the crowd, as does our team of dedicated professionals.

Our case studies demonstrate how we have supported our clients and their power needs:

We understand there are lots of factors involved when it comes to choosing the correct temporary power solution, often it is not practical to have a generator on site at all times due to its size or expense, and sometimes a temporary electricity supply is only required for a short amount of time. We spend the time collaborating with clients to find them the perfect power generator solution.

Should you be in the market for a power generator or backup power support, our team will be happy to discuss your requirements and figure out a tailored quote based on your exact requirements. Whether you are hosting a small outdoor event or in need of backup power for a business, we will make sure everything is in place.

What Are the Benefits of Using BIM Models?

At Shenton Group, we believe that downloading our ready made BIM objects can benefit everybody within the UK construction industry. We look at the benefits of Building Information Modelling and establish why it is vital to use quality models.

What is BIM?

Building Information Modelling (BIM) is a modern design technique that utilises software and a collaborative design process to make the procedure of developing buildings more efficient. Using Revit, Navisworks Manager or Navisworks Freedom software, 3D models are made available to architects, manufacturers, contractors and designers who are then able to work together simultaneously to focus on various stages of the project.  

BIM software streamlines the design of buildings and factors in the analysis of sustainability and the impact on the surrounding areas using real-time modelling.

Autodesk, who developed the Revit software, summarise BIM perfectly –

“BIM is an intelligent, 3D model-based process that helps MEP professionals design, detail and document Building Systems more efficiently. Working in a BIM process gives project teams more insight into designs and constructability, reducing risk and improving outcomes” [1].

BIM is widely used around the globe, while here in the UK; the construction industry uses the BSI (British Standards Institution) BIM strategy as a framework to ensure all models meet specific criteria for their products and services.  

Enjoy the Efficiencies of BIM Modelling

Unlike CAD systems where drawings are individual, the key benefit of BIM modelling software is that it generates all the drawings of the design from one 3D model. The software consistently outputs designs from the central 3D model, making the process of cross checking multiple drawings redundant and enhancing the quality of the end design.

Using BIM makes the design of building and complexes incredibly efficient, allowing teams of architects, manufacturers and contractors to collaborate and design everything required from any location by working off the same database and computer model.

By speeding up the design process, decisions can be made quickly and projects are far more likely to be delivered on time, giving contractors a competitive edge. Using the software also assists with installation, as contractors can factor in layouts and pipe runs to foresee any upcoming issues at the planning stage, saving both time and money.

“Building Information Modelling (BIM) and Digital Construction is an important part of the strategy and is helping to increase productivity and collaboration through technology” [2]

Many organisations make use of third party BIM objects to incorporate into their design, as companies provide readymade objects to download and introduce into the main design.  However, BIM objects must be both accurate and delivered on time or may cause delays or problems with the integrity of the final design.

Construction companies should only use BIM objects from proven partners such as Shenton Group to benefit from this fantastic and forward thinking technology.

Overview of BIM Model

8 Benefits of Using BIM Modelling From a Trusted Supplier

1. Accelerate workflow by downloading readymade BIM objects, ready to use at your fingertips and download directly into your designs.

2. BIM models of Power solutions such as CHP’s and Generators, for example, are accurate and of high-quality when downloaded from the supplier of the equipment.

3. Enjoy cost savings, by not having to spend valuable time modelling BIM objects.

4. Revit and other forms of BIM objects, such as SAT files are reusable, thereby improving drawing office efficiency.

5. Enhance BIM projects by using ready to use detailed models.

6. BIM objects are produced using exact dimensions for accuracy.

7. Using software such as Revit, connectors are integrated in the models, giving other MEP services a means of connecting, to allow for calculations.

8. Specifically relating to CHP and generators, manufacturer models come with a maintenance zone, so you know how much clear space is required around the unit. This enables higher accuracy when space planning.

How Can I Trust the BIM Files I Am Using?

The best way to offset risk is by downloading BIM object files in the form of SAT, IFC, or Revit, provided by reputable manufacturers. This will provide you with the latest up-to-date versions, from an established BIM file provider, with the additional cost saving of not having to produce them.

We have a dedicated internal design department at Shenton Group, which ensures our Revit family models are accurate, concise and are kept up-to-date. All Revit files contain the relevant COBi data required by the Government and provide an exacting product with specific data. These files are at your fingertips to download into your designs and ensure functional and power requirements are met.

At Shenton Group, we want new and existing clients to have a choice about the company and proven BIM partner they use, and the only way for this to happen is for the provision of multiple file types to be available. After all, if you are only providing BIM objects in a specific file type, you can’t guarantee that all BIM designers will be working within the same program, so multiple file types are crucial to avoid hold-ups.

Working with a transparent organisation who continue to adapt to the changing technology is really important. At Shenton Group, we continue to increase the quality of our BIM objects and work with our clients providing technical advice and files free to download to ensure the project runs smoothly and the end client gets exactly what they need.

Power Surveys & Testing to Ensure Power Continuity

Have you ever considered the impact of turning up at work and finding there is no power? For many business owners, the fact that the lights come on and the equipment works without a hitch is something taken for granted. Even to businesses with less obvious risk, power cuts are hugely disruptive but there are options available to safeguard your power supply.

Free Site Surveys to Establish Your Power Requirements

A free visit to your site from Shenton Group to conduct a power survey is hugely beneficial. Our experienced team will assess the risks posed to your business and highlight the vulnerabilities that you potentially have. For many clients we visit, they are simply not aware that there may be a power continuity issue, which is completely understandable. Businesses mainly focus on the day-to-day operation of their facility, and so our power testing and audit service can help overcome and prevent any future problems when it comes to power.  

For clients in the healthcare sector, such as hospitals and care homes, provisions are generally already in place to protect the lives of patients or residents, while those in the financial sector also tend to be aware of the importance of protecting their infrastructure. Clients from these industries are more likely to contact us about what backup power options are the best fit for them, maintenance, or improving the efficiency of their current solution as they understand the value of power continuity.

Rental Generator Being Towed

Impact of Power Failure on Your Business

Outside of healthcare and finance, the impact of power loss may cause untold damage to the reputation of your organisation and leave you falling short of customer expectations.

Do you require lighting or heating to function in your facility? Telephones, computers and other technology all rely on power, and these devices are essential in offering services such as taking bookings, accepting payments and taking care of customers or guests. Likewise, a powerless office means issues with access, lifts and security, and machinery may come to a halt in a manufacturing location. For online retailers, supermarkets and high street stores picking, packing and restocking will be paused, as was the case for a recent client of ours who had to shut down for the day after a leak caused a power outage. They gave us a call and we were able to provide a solution that enabled them to re-open the next day.

Picture the scene, it’s the rush before Christmas, those on the night shift are tirelessly working away on a windy, wintery evening and the power cuts out. The lights go off, the alarms are triggered, work halts and the couriers due to come and collect your stock can’t get in through the entrance. Customer promises are being broken and the fall out could be huge; your reputation ruined and masses of money lost. However, all of this is avoidable.

The Power Options Available

In order to overcome ‘brownouts’, where power dips for a second or two causing disruption, ‘glitches’ where the power drops out for a matter of minutes, and complete ‘power cuts’ that last for hours, we have an array of short and long term solutions to fit every need and budget.

As part of a free site survey, if a permanent onsite generator looks to be the best power solution for your requirements, our dedicated team will run through all of the details and provide an estimation of the cost, plus explain how we will support you throughout the project and ensure correct integration into your facility.

A permanent generator isn’t the only option, a national generator delivery network such as Power Call will ensure a temporary generator is on site in a under 3 hours from the enquiry. With unlimited call outs throughout the year for a low cost-effective monthly subscription, this option is very popular. Or if you need a generator on site for a longer period of time, you can hire one.

Power solutions are best discussed in depth, with the costs weighed up and all the advice considered. A site assessment to review your power continuity plan costs absolutely nothing and is conducted by an experienced Shenton Group engineer. We will help you consider what works, and any limitations and considerations you may not have thought about, such as fuel types, acoustics and loads. Shenton Group will provide a new outlook as to how best to secure your power continuity moving forwards.

Have a Backup Power System In Place? Get it Health Checked

Shenton Engineer Inspects Generator

If you have a backup power system in place, you may already have benefited from a generator that restores power in under thirty seconds and never need to wait on the delivery of a generator for power to be restored. However, as a depreciating asset, a generator will require regular testing and maintenance for it to perform efficiently during an emergency.

Maintenance Contracts

Shenton Group is equipped to look after any model of generator, as well as any UPS or CHP system you may have in place. We provide clients with choices based on their budget and individual requirements, such as fixed cost contracts delivering an all-inclusive approach, or lower-cost contracts which cater for added extras when required.

With nationwide coverage, a 24/7 help desk and complete monitoring of your generator available, leave the power in our capable hands. Call Shenton Group about a Free Site Survey or Generator Maintenance.

Shenton Group’s Latest Rental Projects

Our reliable rental backup generators have been in high demand in the last few months, with many facilities under greater pressure to ensure their power supplies are secure, while temporary locations requiring power have been installed UK wide to help cope with the impact of COVID-19.

Assisting a Retail Client

As we entered the initial lockdown period, there was considerable strain put on some retailers to cope with the demand of customers buying in bulk, with shelves left empty up and down the UK.

One retail client called us when they had to close the store after they had a leak and power failed. Within 2-3 hours, we had a rental engineer and team leader on-site to arrange a same-day solution, which meant the power was back up and running by 4 pm, allowing the store to open the doors the following day to continue trade.

The retail distribution giant required a 1250kVA temporary generator solution for a month to help them with skyrocketing demand.

Unfortunately due to COVID-19, the store was then closed and most of their staff Furloughed. We then downsized the rental generator to a 500kVA as only essentials such as freezers, lights and security cameras needed to be powered. This solution provided fuel and cost savings to the client as the generator is running 24/7.

Generator Rental Solutions for Multiple Sectors

Short and long term hire

Our team are more than happy to find a power solution for a period that suits your needs. We provide rental generators for use on a single day, right through to providing clients with a generator to rent for a few years, and we can support and maintain the generator throughout the rental agreement too.

Shenton Rental Generator Transportation

Assistance for a Care Home

We took a 500kVA rental generator to Richmond Care Villages for a day’s worth of testing. The COVID situation drove the decision to make sure that the care home could backup their whole complex should there be an issue with their mains power supply. Keen to safeguard their residents during the pandemic, they sought our expertise and we were able to help them understand the different solutions on offer, including our emergency power service Power Call, a subscription based services that provides unlimited generator call outs 24/7 at no extra cost. 

The variety of sectors we help extends to the government – having provided a rental generator to a military base in Wiltshire to run their incinerator. Our experience in helping MOD clients also led to us conducting some power continuity testing at the same military facility.

Additional projects have included providing a rental power solution for a hotel in South Milford, supplying them with 1250kVA generator for around a month while they conducted maintenance work on their switchgear. Our team also recently deployed a smaller 30kVA generator for another client for a period of 2 years to provide a power solution for a workshop.

Power Continuity in Times of Uncertainty

First and foremost, the biggest change in the nature of work carried out by Shenton Group has been handling enquiries from temporary hospitals, medical facilities and testing stations throughout the UK.

We continue to maintain, monitor and take responsibility for a number of Generators, UPSs and CHPs on key NHS sites, education campuses, national water boards, and data centres, all regarded as sectors of national importance. This work has now evolved into supporting temporary healthcare facilities too.

Shenton Generators

Many clients, new and old, have also used the lockdown period as a window of opportunity to review their power solutions. The pandemic has resulted in action across some sectors to review their backup power options and has pushed the demand for generator testing and maintenance while staff are off-site. Our team have been out and about putting quotes together for a variety of clients to help them remove ‘reliable power supply’ from their list of concerns.

Moving Forwards

While many outdoor events reliant on generator hire planned for the summer ahead have been cancelled, such as weddings and festivals, other opportunities have come about with more sectors taking power solutions more seriously.

Working with some very large clients on backup power solutions, we have built more relationships with construction contractors, working on huge distribution centre projects for retail and online shopping giants. Our knowledge and expertise in power solutions have potentially opened the door to new and exciting future projects.

During COVID-19, many clients identified Shenton Group as a key supply partner and requested that we remain open and operating. Shenton Group’s engineers have been operating, and continue to operate, around the country on these key sites, albeit in slightly reduced numbers in accordance with the government guidelines.

Get In Touch

No matter which sector you operate in, the power supply is essential, especially at times when there is added strain on the National Grid. Whether you need additional power security during the next few months, or you would like to embrace minimal disruption to your day-to-day operation while staff are off-site, we can help you enhance your power solutions. Call us today.

Has COVID-19 Impacted Bandwidth Limits?

COVID-19 has forced millions of people to work from home and children to study away from school, which has put additional pressure on bandwidth, (The average rate of data transfer through a communication path, such as phone lines or fibre) and increased the importance of power continuity for data centres.

Openreach (BT) revealed some data about the changes to weekly network traffic in the UK. London saw a jump of 28.58% from a normal working week in February compared to the week commencing 20th April, as published by ISP Review.

The majority of increased network traffic levels occurred during the daytime, with normal levels resuming in the evenings, interestingly still lower than the peaks experienced annually around Christmas time. Openreach, one of the UK’s main connectivity suppliers have stated that they have experienced no issues with coping with the additional workload.

Despite applications such as Microsoft Teams, Zoom, Skype, Houseparty, Netflix and Amazon Prime used on a daily basis by millions of households, Openreach is not anticipating any bandwidth problems in the weeks and months ahead.

Did Netflix Reduce Streaming Quality?

Back at the beginning of the pandemic, Netflix cut down data consumption to ease internet capacity as more people switched to working from home in Europe, Australia, New Zealand and various other nations, as internet service providers were concerned about the additional volume of traffic. With 11 million subscribers in the UK, the main impact was on the Ultra High Definition customers but there has been very little negative noise from users. By reducing picture quality, Netflix reduced data consumption by 25% easing the pressure on bandwidth in Europe and elsewhere.

Netflix Adjust Bandwidth During COVID-19

Broadband Connections Pushed to the Limit

The BBC, however, reported varying degrees of broadband speeds are making life more difficult for some people across the country who are trying to work, learn or enjoy entertainment.  

In the article, it says ‘In theory, 95% of premises should be able to access superfast broadband but take-up of services remains low.’ With many households on the government Furlough scheme, most are keeping a watchful eye on outgoings.

Video calling services are used to connect many families, friends, colleagues and classrooms, but slow broadband speeds cause audio and picture quality to be poor, demonstrating that there are still issues, especially when families try and use the internet at home simultaneously.

Video Calling Impact on Bandwidth

Why Has My Internet Connectivity Worsened?

A good guide to how many pieces of equipment can run at any one time is to see how many CAT ports are on the back of your router. Most broadband routers only have 4-5 sockets, as this is the limit of how many pieces of equipment can be used at any one time. So if your PC and TV are connected to your router via cable, this leaves you with connectivity for 3 spare devices, after this, you will receive reductions in bandwidth.

Some tips to try to improve bandwidth include:

  • Where possible plug a device in with an Ethernet cable
  • Make sure the router isn’t surrounded by clutter
  • Upgrade your broadband
  • Download films to devices at quieter times when others aren’t online
  • Don’t plug routers in on extension cables

Protecting Data Centres in the Pandemic

Data centre operators fall into the ‘keyworker’ bracket providing vital services to the nation, enabling people to work remotely and provide access to information online.

This increase in the number of people working from home has brought added pressures to data centres to be fully functional around the clock.

Woman Working From Home During COVID-19

It is now more important than ever for datacentres to have a reliable backup power supply in place if the national grid was to go down. Need we be reminded of last years power outage that brought chaos, with big companies paying out millions of pounds in compensation for the disruption caused.

Power security for business continuity has been one of the priorities for Shenton Group during these testing times, safeguarding our clients from blackouts as well as ensuring vital data centre equipment remains operational.

Moving forwards and looking beyond the end of the pandemic, data centre growth is set to continue. Employees have demonstrated the ability to be productive while working from home utilising cloud technology and services such as Microsoft Teams, which will only drive the use of backup systems and IT infrastructure, both reliant on data centres.

Data Centre Power Supply Specialists

We understand that downtime is not an option for sites such as these and have the experience to integrate reliable solutions with no break in your service or power. We have a vast portfolio of data centre projects and can give your organisation confidence that operations can function 24/7 with complete power security.

Some examples of projects where we have provided UPS solutions:

Major UPS and Generator Project for Telecoms Data Hosting Centre

Rapid Replacement UPS System for Hospital Operating Theatre

Recommendation from RAF Lossiemouth

How Does a UPS System Work?

A UPS normally sits between the generator and the critical equipment it is covering, and converts normal AC mains power to DC battery stored energy, before converting it back into stable AC power.

This protects essential equipment from voltage dips and loss of power. In the event of a mains power failure, the energy stored in the UPS battery will run the equipment until a standby generator comes online and takes over.

Our team of UPS experts continue to provide service to our clients and should you need a UPS solution or any support with a critical power system, we are available to assist.

Why Is Uninterruptible Power so Important for Critical Sectors?

Critical healthcare facilities, sensitive data centres and communication networks can ill-afford any loss in power. The fallout from losing data, vital information or disrupting medical equipment is simply unthinkable, especially in the current climate.

Without a UPS in place, there can be a gap of a few seconds when there is no power whilst the generator starts up, causing untold damage. A UPS system is the bridge between mains power being lost and a backup generator coming online. In the event of power failure, AMF panels will react automatically and activate your generators, but it can be up to 15 seconds until the generators are up to speed and online. UPS systems are the ultimate protection for critical equipment, ensuring your electricity supply experiences zero downtime.

Other benefits of UPS power supply systems include stabilising your power source and preventing disturbances commonly caused by spikes and surges. Our extensive range of UPS solutions are compatible with most standby generator backup power solutions.

UPS Maintenance and Monitoring

Choosing a correct level of cover for your critical power system is every bit as important as the installation. Any form of backup power, generator or UPS system needs regular maintenance in order to be completely reliable at the most critical moments.

Shenton Group offer 24/7; 365 days a year cover for those who operate in critical sectors such as healthcare, data centres and communication facilities. With a Nationwide response team at your disposal, power continuity support plans give access to 24/7 technical help and support, guaranteed response times and any maintenance is provided up to manufacturers standards.

What is Fuel Polishing?

Fuel polishing is a cleaning process that removes any harmful sediment in your generator fuel tank, which if not eliminated, can have a detrimental impact on your backup power system. A fuel polish involves removing the diesel from the storage tank, filtering it, removing the redundant fuel, and then feeding the remaining clean fuel back into the tank.

Diesel stored in fuel tanks for long periods can begin to deteriorate and become contaminated which will have a negative impact on a diesel generator, and in worst-case scenarios can cause system failures which could be disastrous, especially for an emergency backup generator. 

Fuel polishing also helps your generators to run more efficiently, as with the cleaner fuel you will use less, therefore, saving you money and fewer break downs.

How a Fuel Polishing System Works

At the bottom of an unchecked fuel tank, there is likely to be a build-up of damaging sludge, which can cause issues for different parts of your generator as it runs through the system. Water and bacteria build up over time because of natural processes, contaminating your fuel and rendering it unfit for use. The solution to prevent this is to filter the diesel using a fuel polishing system. 

Some generators are fitted with their own fuel polisher and gauge, the benefit of this is the fuel is cycled and cleaned automatically. This means you do not need to wait for an engineer to come out, you save money on your maintenance plan and you further decrease the chances of contaminated fuel. Some of our clients find this option very useful. We can fit fuel polishers to new and existing generators, subject to conditions on site.

For those that don’t have a fitted fuel polisher, Shenton Group provides a professional fuel polishing service that comes to you and ensures your fuel is cleaned safely and without damaging the environment.

Shenton Group’s Fuel Polishing Process

  1. Carefully the fuel is extracted and filtered via a series of processes removing any contamination
  2. The tank is also cleaned and any solids or debris are taken out
  3. Before the clean fuel goes back into the tank it is tested to ensure it meets industry standards 
  4. The clean fuel is then treated with a chemical biocide to slow future bacterial growth 
  5. The remaining contaminated fuel is ethically disposed of

How Important Is Diesel Polishing for the Upkeep of a Generator?

Backup generators are vital and expensive pieces of equipment. It is certainly in the best interest of your operation to keep on top of regular maintenance and servicing in order to prolong the life of the generator and to keep your power supply secure. 

Fuel polishing can prevent engine breakdown, fuel starvation, blocked filters, and water or any other contamination entering your generator. Contaminated fuel will cause your generator to fail and the cost of replacing parts can be expensive. Fuel polishing also prevents the need to replace the entire fuel supply in the tank, an expensive and unnecessary outlay. 

Key Benefits of Fuel Polishing

When fuel becomes contaminated and is left too long without polishing, the whole fuel supply in the tank might need to be removed and disposed of at great cost. This is hugely wasteful and environmentally damaging. 

A more responsible and cost-effective approach would be to make use of a maintenance contract and regularly schedule in fuel polishing, which is less expensive and far better for the environment. 

  • Fuel polishing will help prevent the build-up of sludge in your generator and will prevent water from entering the generator. 
  • Depending on your generator set up fuel polishing systems can be connected up to your fuel supply and can run causing no disruption to your day to day operations, and so your contingency power supply can continue to be called upon at any given moment. 

Does My Diesel Supply Need Polishing?

Every backup generator will need to have its fuel polished at some stage. To establish if the fuel needs polishing, a sample is taken. If the fuel is in good condition and meets required legislation then nothing other than continued monitoring will be required, while if there are unwanted elements in the fuel then intensive fuel polishing will have to be conducted to prevent any damage to your generator. 

How Often Should Fuel Be Polished?

This depends on each individual generator set up, but in the main, for a backup power system, the stored fuel should be tested at least once a year. The results of the sampling will dictate whether the fuel needs to be polished or not.

A maintenance plan with a professional supplier will ensure your equipment and fuel will be monitored by experts who will also schedule visits to take care of the upkeep of your generator and quality of your fuel. 

Shenton Group gives you the option of including the cost of fuel polishing as part of your maintenance contract. We routinely check the generator fuel every 12 months and run a detailed report to establish if fuel polishing is required. This is critical for the protection of your asset and the reliability of your backup power system. 

With the involvement of specialist equipment, it is understandable that some clients may initially feel the process of fuel polishing to be pricey, however; it is a far more cost-effective route than replacing an entire batch of fuel and disposing of the old contaminated batch.

Most importantly, you will increase the life span of your generator and avoid break downs which again can be costly for you and your operation. For example, if you run a food chilling warehouse and the chillers lose power, that could cost thousands of pounds and hurt the businesses reputation. Nobody needs that headache!

Enjoy the Financial Rewards of a Quality Assured CHP System

A CHPQA (Combined Heat & Power Quality Assurance) quality mark will assist your organisation in getting the most out of your system financially, as a ‘Good Quality CHP’ qualifies your company for a range of incentives.

What is the CHPQA?

To certify the quality of CHP systems in the UK, the government launched an initiative for assessing combined heat and power systems, which falls in line with the requirements of the EU Directive 2012/27/EU on Energy Efficiency. The scheme measures the efficiency and environmental performance of Combined Heat & Power systems, and a ‘Good Quality CHP’ classification opens up financial rewards.

Do you qualify for Combined Heat & Power Quality Assurance?

Combined Heat & Power Systems are often referred to as ‘schemes’. Find a list below of some basic criteria for those CHP schemes that qualify for CHPQA.

Simple Scheme Qualification

  • Generating capacity < 2 MWe
  • Single reciprocating engine
  • Single conventional fuel used
  • Heat recovery with no waste heat rejection

Complex Schemes

• Generating capacity equal to or greater than 2 MWe
• Prime mover, not a single reciprocating engine
• Non-conventional fuel used
• Certain Boiler(s) included within the scheme boundary

An Annual Process to Maintain Your CHP Quality Mark

To obtain CHPQA there is a self-assessment process, which can vary depending on the complexity of the CHP scheme. You must complete this process once a year to ensure each CHP scheme is still effective.

As long as your site and CHP meet the requirements, and the CHPQA application is submitted correctly you should meet criteria with no issues. However, they can be a little complicated for the untrained eye, and that’s why Shenton Group offers assistance with the CHPQA process and provides guidance to ensure it is done properly.

4 Tips to Make Sure You Obtain or Retain CHPQA

  1. Accurate Planning. New CHP schemes must be sized properly based upon accurate energy data as failing to do so may result in missing out on obtaining CHPQA, and may also cost you money. Failure to plan properly could lead to a scheme too big to run efficiently, or not large enough to obtain suitable cost savings.
  2. Schedule Regular Maintenance. Regular maintenance will enable your CHP system to run efficiently, ensuring the best ROI. As the UK’s sole provider of TEDOM CHP units, Shenton Group are the experts in CHP and can support you in looking after your system.
  3. Recording Usage. Metering and sub-metering of the fuel used and the heat & electricity produced by your CHP will not only help you keep a tab on the efficiency of your system, but the use of accurate MID certified metering is a requirement of CHPQA. Without these measurements, obtaining a certificate is not possible.
  4. Be Certain That CHP Is Principal Provider. Your CHP system needs to be the main provider of your heat.

Avoid the Rising CCL Rates with CHPQA

(Climate Change Levy) CCL is an environmental tax on electricity, gas and solid fuels. The logic behind it is to push businesses and organisations to choose more energy efficient methods to power their operations.

The CCL rate for gas fuel will be increasing in 2021, to be as much as 60% of the CLL rate for electricity. This makes CCL exemption very attractive for businesses. Unless you are a charity or a huge energy user, the likelihood is you will be liable to pay this tax, but CHP systems can reduce your environmental tax bill.

CHP schemes that obtain ‘Good Quality CHP’ status are exempt from CCL payments on the gas they use to generate their power.

Other Financial Incentives

Organisations with ‘Good Quality’ CHP can benefit from enhanced business rates. Depending on your location, Shenton Group can help you investigate this avenue at the planning stage.

Annual Investment Allowance (AIA) – You can claim AIA on most plant and machinery up to the AIA amount. The AIA amount has temporarily increased to £1 million between 1 January 2019 and 31 December 2020.

Will the Coronavirus Have an Impact on the Energy Network?

The self-isolation measures in place due to the Coronavirus outbreak mean that many people will be set up to work from home, which may put more pressure on our energy networks and our power supplies.

Demands on our Critical Infrastructure

Despite the challenges that arise due to the Coronavirus, many businesses will continue to operate to their best ability in these unusual circumstances. This will involve many employees working from home rather than sharing large communal office spaces.

Homeworking does increase the demand for our energy networks compared to the normal requirements of workers using office areas, where both heating and electricity come from shared supplies. However, energy suppliers such as Scottish Power “point out that it is not that much different to Christmas time when most of the population takes a couple of days off”*. A period of working from home should be manageable but with the uncertainty of how long this remote way of working will be recommended, it could put a strain on telecommunication centres and other energy suppliers.

*BBC News Scotland

Lessons from Europe

In Germany, the association of local utilities (VKU) stated that the ‘Energy supply currently is neither in danger nor impaired’.** Grid operators are taking the same precautions as advised for any employee in order to minimise the infection risk, without compromising the service levels provided.

**Clean Energy Wire

In addition, the shutdown of sporting events, mass gatherings, social events, pubs, bars and cinemas will also equate to less power used on the continent, with similar measures coming into force in the UK. Manufacturing is also likely to be scaled back and even halted as businesses look to minimise the risk of their employees becoming unwell.

Energy & Communication More Important Than Ever

Nationally the country will need to work collaboratively to contain the pandemic and both power and internet connectivity will be relied upon to enable people to work and operate remotely in isolation. Businesses will depend on the power networks to continue providing a service and to remain connected and informed of any internal updates.  

Constant power supplies for hospitals and healthcare locations will be imperative and Shenton Group will remain operational in order to support all of our customers, no matter which sector they operate in.
