Generators to Provide Backup for Homes and Business for Next 10 Years

“The UK is facing an energy gap right now and for the next decade”, according to Ian Thompson, Managing Director of Generator Warehouse. At a recent Power Generation forum at the London Hilton on Park Lane, Thompson stated, “Demand for electricity will outstrip supply by more than 48% over the next 10 years which will have severe consequences; black outs for some neighbourhoods, power cuts for homes not just in remote areas and power outages for businesses. We are seeing more and more people come to us for advice on what to do in the event of power cuts, what fuel to choose and how a generator system will operate. Power cuts are happening now but go largely unreported.” said Thompson

Numerous studies show that phasing out of ageing nuclear reactors without plans to build a new fleet of cleaner energy electricity plants, will combine to create catastrophic failure and an inability to supply. Repeated short sightedness by UK Governments over the last 25 years has led to the crisis.

“Under current policy it is almost impossible for UK electricity demand to be met by 2025.” said Jenifer Baxter, head of energy and environment at the Institution of Mechanical Engineers (IMechE), which published the report entitled Engineering the UK’s Electricity Gap, on Tuesday 26th January 2016.

Reforms to the electricity market brought in under the previous Conservative / Liberal Democrat coalition government are also not helping to encourage construction. Shambolic attempts to encourage energy efficiency such as the ‘green deal’ to insulate houses, which was scrapped, have proved poorly thought out and not manageable. Just one new nuclear reactor might be ready by 2025; that is the stark reality, a real indictment on the UK’s long term energy strategy.

“The UK is facing an electricity supply crisis,” Baxter warned. “As the population rises, and with greater use of electricity in transport and heating, it looks almost certain that electricity demand is going to rise. However, with little or no focus on reducing electricity demand, the retirement of the majority of the country’s ageing nuclear generators, recent proposals to phase out coal-fired power by 2025 and the cut in renewable energy subsidies, the UK is on course to produce even less electricity than it does at the moment.”

She said: “We have neither the time, resources, nor enough people with the right skills to build sufficient power plants. Electricity imports will put the UK’s electricity supply at the mercy of the markets, weather and politics of other countries, making electricity less secure and less affordable.”

“The supply gap (the lack of ability to produce power required) could be equivalent to as much as 55% of electricity demand by the middle of the next decade,” according a new study highlighted by Thompson.

Increasing numbers of home and business owners are installing independent generators which will automatically switch on as soon as the mains power fails and keep running until it is restored.  Such systems mean that a home can continue to function albeit in a more limited way – fridges, freezers, central heating pumps can all run as normal. Businesses likewise can continue to operate if their servers are supported with an appropriately sized generator; production machinery and office computers will continue to run even without mains.

One company that has been at the forefront of supplying and installing such systems for several years is Yorkshire based YorPower.  Managing Director, Ian Thompson, told us that the company has increased its already significant stocks of generators so that once a customer has recognised that their home or business is exposed to the risk of losing mains power they don’t have to wait long to have backup installed.

Latest emissions regulations on the use of diesel powered generators 2016

Diesel emissions have dominated recent headlines causing confusion and misunderstanding for consumers and industry suppliers alike, more recently with the use of diesel generators. Leading manufacturers are under immense scrutiny – how has this impacted other areas of diesel powered engines, both road going and non-road going?

The driving force behind the regulation change derives from recent studies that primarily focus on the damaging impacts diesel emissions are having on air quality. The primary pollutants are Oxides of nitrogen (NOX), Carbon monoxide (CO), Hydrocarbons (HC) and Particulate matter (PM). Whilst carbon monoxide is a common player in the emissions battle, oxides of nitrogen (NOX) has faced much more questioning in more recent emission reports. NOX is thought to be a key element in the rising number of cancer related illnesses. EPA estimates that by 2030 the treatment of these emissions would annually reduce 12,000 premature deaths and 8900 hospitalisations.

The increased awareness of the changing emission regulations can only impact manufacturers of power generation equipment. Maintaining high performance levels whilst implementing tougher legislations is a key challenge facing many diesel manufacturers. The challenge is to reduce the production of NOX at source well enough to avoid other more costly measures.

Today’s modern diesel engine is the cleanest form of combustion engines on the market. With new developments in technology, specialist after treatments could be the only solution left for diesel manufacturers. CEO’s must embrace the cleaner legislations of Tier 4 in order to survive the evolving consumer expectations for cleaner, affordable fuels. Tier 4 emission limits require up to 90% reduction of NOX and 50% of PM, but the initial stages of the tier only scratch at the surface. With the following final Tier 4 limit imminent a further 88% reduction will soon follow.

Manufacturers face a hard battle to introduce Catalytic reduction and regenerate filters without making diesel engines much more expensive. Stationary diesel generators are not only facing pressure to comply with Tier 4 legislation, they also risk losing the key denominator separating diesel generators and their gas competitors. With new tier 4 legislations adding cost to the supplier, surely the ripple effect will impact on consumers. If stationary diesel engines fail to supply the same competitive prices they currently offer, diesel generators could soon face extinction.

Dirty Diesel Generators Cleaner by YorPower – Emissions Compliant Generators Tier 4

Increasing emphasis is being placed not just on efficiency and fuel consumption but now also on emissions.

The European Union has established categories of allowable emissions in non-road diesel engines called Stages I, II, III(A), III(B) and IV. Each increasing stage specifies lesser amounts of four specific pollutants that are permitted, based on the number of grams per kilowatt-hour of the compounds present in diesel exhaust.

These regulations primarily affect portable diesel generator sets (18 kWm to 560 kWm) and other non-road and industrial engines. At the present time, the EU does not regulate emissions from stationary diesel generator sets such as those used for prime, peak shaving, load shedding or emergency standby power. All non-road equipment, such as rental generator sets, were required to meet Stage II requirements effective 1 January 2007 and Stage III(A) by the end of 2015.

In the EU, four main constituents in diesel exhaust are controlled:
• Nitrogen oxides (NOX)
• Hydrocarbons (HC)
• Carbon monoxide (CO)
• Particulate matter (PM)

For Stage IV and beyond, some non-road diesel engines will require selective catalytic reduction (SCR) after-treatment systems to reduce NOX, HC and CO to regulated levels. Stage IV PM reduction will require regenerative filters on the exhaust to trap and eventually oxidize the soot particles.

The YorPower range of Stage III(A) Emissions Compliant generators includes units powered by both Perkins and Cummins engines but other options are becoming available using engines from different manufacturers.

Standby Diesel Generators

YorPower Generator

YorPower Generator

Standby diesel generators are used by businesses and remote domestic dwellings in the UK and, where backup power is needed, all over the world. The ever increasing demand on mains power networks coupled with the reducing number of power stations means an alternative supply is essential for businesses to function without interruption.

In developing countries, where networks are not capable of delivering increased demand, standby generators are typically used as the primary source of power for homes as well as for commercial use. Diesel and petrol/gasoline is cheap in many of these countries so running a generator is an economical way to provide power.

Why buy generators and not something more efficient or less damaging to the environment? The answer is wholly financial; a standby generator is the cheapest capital purchase by some distance and will provide quick, available power where and when needed. It is simple maths. Compared to solar or other non-fossil fuel alternatives, generator power, using diesel is by far and away the most cost effective. Diesel generator efficiency.

Budgeting for, and investing capital in, standby power for disaster recovery (link to blog disaster recovery) in developed countries makes good sense. However, when using generators as the sole or primary source of power in the developed world as an alternative to mains electricity, the costs are high. For example, in the UK if your electricity bill over 10 years was, say, £10,000 the cost of buying and running a generator over the same period would probably be more like £50,000! Combined Heat and Power (CHP) systems can be an effective way of maximising the total energy produced, but still fall some way short. Environmentally, generators are a long way short of ticking the ‘green box’ but until grid supplies worldwide are beefed up and can cope with current and future power demand or a genuinely viable green alternative presents itself, a standby diesel generator will remain the first choice for backup power.

Like it or not, environmentalists can do very little about the predicted spiralling increase in the number of generators predicted over the next three years, even in the developed world. To underline this point, last year Hurricane Sandy devastated New York City and other parts of the State. The storm occurred on October 25th 2012; domestic generator demand was so great immediately following the event that people had to wait until April 2013 before they could get their emergency cover in place. In the US, regulations governing C02 emissions is as high as anywhere in the world, ironic considering the average US citizen consumes 6 times more power than its nearest rival. On the flip side, Americans typically install gas generators as the preferred choice for their domestic standby power, which, whilst significantly more expensive in terms of capital outlay than diesel, are far cleaner and produce much lower emissions.

In summary, the lack of alternatives to standby diesel generators for backup and emergency power means generators will be around for some time to come.

Backup Generators and Disaster Recovery Planning For Your Business

Untitled Document

Power Cut

In the majority of developed economies the likelihood of a major event causing your business to cease functioning is low.  For example, backup generators in the UK are rarely called into action because the power supply, provided by the National Grid and supported by utility companies, is reasonably reliable.  However, you might be surprised by the actual number and frequency of power outages that occur, particularly in town centres, even in the UK and USA.  One major city centre close to YorPower’s headquarters has suffered more than four major power black-outs every year for several years and OFGEM warns that the situation is likely to get worse.

The situation in many developing economies is even more extreme and infrastructure fragility means that even where a supply network exists it is likely to be very unreliable with frequent and long lasting periods of no supply.  In many countries in Central America and Africa in particular the infrastructure is so unreliable that any business must be prepared to supply its own inputs.

The purpose of a Business Disaster Recovery Plan (or Continuity Plan) is to make sure your business is ready in the event of the unavailability of main services (for example: electricity supply) and to restore services to the widest extent possible in a minimum timeframe.

Once your Plan has been finalised it is essential that preventative measures are implemented to minimise operational disruptions and to recover as quickly as possible when an incident occurs.

This process is challenging enough for a large business but can be even more difficult for smaller organisations with fewer staff and resources but, as ever, proper planning can mean the difference between the survival or demise of your business.

The scope of your Plan will depend to a large extent on your business processes.  The simpler the business, the simpler the Recovery Plan. So your first step should be to list your business processes.  Then, next to each process, list all the systems that each process depends on.  For example, if you manufacture an item using a machine you may depend on electricity to power the machine, a computer to control it, a delivery system to provide raw materials and a packaging system to prepare the finished item for despatch and, of course, the operators you depend on.  You will notice that, even in this simple system two other systems are mentioned – each will have its own dependencies.

When you have your list of systems and the inputs they depend on you can decide how important each process is to your business.  You should consider what effect the stopping of each process would have on your business.  If it is critical then your plan needs to include the actions you will take to replace the input in the event of the failure of your current supply.

For example, if one or more of your critical business processes depends on the constant supply of electricity then you need a plan to provide that electricity when the main supply is cut off.  One overriding critical process for most businesses these days is the business server and associated computers.  We all know the frustration of a computer crash causing loss of unsaved work.  Imagine the damage caused when your whole computer system shuts down – not just loss of data but also loss of control systems, loss of communications and staff unable to do any work.  In such circumstances your Recovery Plan could well include an Uninterruptable Power Supply (UPS) to provide instant power for the few minutes it will take for a backup generator to come up to power.

Your Plan should also consider the length of time it could take to implement replacement and whether the input is so critical that you would not be able to wait for replacement.  Remember, some of the conditions that could lead to the loss of a critical input could easily affect other businesses too.  In that case there could be a lot of competition for replacements.  For example, if a water failure caused by a pipeline defect effects your whole area then all your neighbours will be trying to obtain water via tankers at the same time.

You should consider either setting up a contract for the priority supply of an alternative input or have that input in place and on permanent standby.

For example – if your business would come to a halt without electrical power (and remember that means servers, computers, lights and heating systems – not just machinery and equipment) then you could be well advised to add a backup generator to your asset list as soon as possible.  The capital cost is unlikely to be anything like the cost of losing even half a day’s business.

However, it must be remembered when specifying a diesel generator that many electrical devices, including most machines, require more power to start than they do while running.  Any backup generator must be capable of handling the start-up load, not just the normal running load, of all your devices – assuming you will start them all at the same time.  A phased start will mitigate this need but will have to be carefully planned to avoid overload.  For free advice on the size of generator your business needs contact YorPower on +44 (0)1977 688 155 or email sales@yorpower.com.

Perkins Filters, Fleetguard Filters, Lister Filters, Cummins Filters, FG Wilson Filters


Counterfeit products and non-branded filters are commonly used in some markets, sometimes knowingly, sometimes not, especially in parts of Africa.

YorPower Spares and Filters

There are some pretty convincing imitations from the Far East but using them puts your own or your client’s equipment in jeopardy. It is easy to overlook the importance of correct filtering of air, fuel and lubricating oil and buying cheap filters can lead to costly breakdowns and can even cause engines to seize up completely.

Branded, OEM, filters designed specifically for particular products are essential. The Warranties provided by generator manufacturers including FG Wilson, Perkins, Fleetguard and Lister will be invalidated unless OEM guidelines are followed.  The scheduled replacement of oil and air filters is not only sensible but can also save you thousands of pounds over the life of a generator.

Fuel is frequently contaminated in places like Nigeria and any shortcuts in fuel filtering will prove massively costly if the engine malfunctions as a result.

Oils have to be kept clean and free from particles to prevent wear and tear and to return harmful particulates to the sump so preventing them from damaging the engine. Regular replacement of oil filters ensures continuous purification of your oil as well as removing the trapped particles from the system completely (upon removal of a clogged filter element).

Clean oil protects your generator engine from wear and subsequent breakdowns and your oil is only maintained by proper servicing and monitoring of your filtration systems.

YorPower hold stocks of all popular engine filters including Perkins, FG Wilson, Volvo, Fleetguard and John Deere and a huge range of other Original Spare Parts

Used Generators – Things To Check Before You Buy

Used Generator

YorPower apply the same high standards of engineering, workmanship and service to their used generators that they do to the ones they build

When buying a used generator, just like buying a used car, you need to be confident that you’re not going to finish up with an expensive problem.

You should see evidence of the number of hours it has run and ideally that the generator has been serviced according to the manufacturer’s recommendations. But, just like a used car, can you be sure that the running hours stated on the control panel are genuine, that the service records are accurate and that the important filters and lubricants are correct? Not always! Sometimes it is just not possible to obtain the right information and that is why the buyer should be mindful of who the seller is.

Once you are confident that you can trust the information, buying a used generator can be a very efficient way of reducing capital outlay if your application is for standby power.
Every Used generator set should be tested and follow a staged process prior to sale:

The first step in ensuring reconditioned generators will meet expectation is to select good quality equipment. That will mean shopping around and doing your research. It is prudent to review an engine’s history and maintenance regime before purchase or acceptance in whole or in part exchange. Used generators that are nicely painted, have a new control panel fitted or look newer than the hours recorded (or stated by the seller) should ring alarm bells – be careful, they might have been used and abused.

Initial Load Test
Using a calibrated load bank to test the capability of the engine and complete unit under duress is a very good way of uncovering any failings. A load test is not unlike taking a used car and driving it hard on a motorway for an hour. A full load test up to 100% of capacity is recommended. It will help diagnose any potential shortfalls and should help you make an informed choice.

Repairs & Upgrade
You should always request a new control panel as part of the purchase deal as analogue units are not compatible with many modern telecommunication devices that could be fitted and be useful at a later date. The control and alarm system may include an auto start with automatic mains failure capability, remote start, modems, GSM’s and acoustic enclosures could be upgraded or retro-fitted. Consumables such as filters, belts and hoses should be checked for ware and be replaced if appropriate.

Final Load Test
If a used generator has failed the initial load test it may require another if the faults uncovered were considered to be minor and the purchase still worth pursuing. The unit should be tested again on load for a minimum of one hour and with staged loads up to 100%. During test both the engine and alternator should be monitored for speed and voltage characteristics to ensure the pre-requisite demands are met. A test certificate should be produced.

A good source for used generators, particularly large generators, would be hospitals, universities, telecommunication centres, banks and data centres. More often than not large generators installed for backup power in the UK are rarely, if ever, called into action and so typically have very low hours and are in good condition.

YorPower apply the same high standards of engineering, workmanship and service to their used generators that they do to the ones they build and manufacture as new; all carry a full Load Test Certificate.
