Large Industrial Generators

At the heart of what we do is a desire to innovate. If we can design and produce more efficient generators that are lighter, quieter, use less fuel, and are more reliable, we will continue to grow and expand our business.

Recent innovations include:

  • Fully reportable remote monitoring devices installed on generator control panels allowing diagnostic reports to be conducted off-site
  • New mobile and portable generator kits allow heavy diesel generators to be moved more easily when on site
  • Start on-demand generator systems which reduce fuel usage as engines only run when the demand requires it
  • After treatment on exhaust silencer systems to reduce engine emissions that contain N0X and Carbon Monoxide.


A generator manufactured by YorPower can be bought on most continents of the world. With Headquarters in the UK and bases in Kenya, Mexico, Bangladesh, Australia, Ghana, Nigeria and dealers in many other countries, YorPower operates on a global scale.

We have diesel generator holding facilities in key strategic locations and we are always keen to hear from people and businesses who want to become YorPower distributors at home and abroad. If you want to be a dealer we would be delighted to hear from you.


What is the cost of a commercial generator?

This really depends on the size and brand of generator required. If you give us more details on what you need to power, we’ll be able to send you a quote for the most suitable generator.

Why are some generator brands more expensive?

Usually, because they are built using higher quality components and therefore have a better standing in the market, are well known and trusted and have wider consumer appeal than those less well known. Sometimes the warranty is for a longer period.

Should I buy petrol or a diesel generator? What is the difference?

A petrol generator will normally be smaller, will typically be used for prime power applications and not for standby or backup, a petrol generator will frequently be portable and can be moved from place to place easily. A diesel generator will be more economical on fuel, they can be used for prime power and backup power, and they can be portable (for the hire sector) but are frequently part of a fixed installation.

How noisy are large generators?

Noisy! Petrol frame generators can be quite noisy, Petrol inverters (Suitcase generators) are relatively quiet, diesel generators can be sound attenuated so that noise levels are reduced, however, an open frame skid diesel generator will be noisy. If you require a silent generator please let us know and we can recommend a suitable generator for you.

How do I work out what is the best backup power generator I need?

Working out the best generator to get: 1) Establish the max power you intend to support in kW’s 2) Will I need to backup every appliance or just the lights? 3) How long will I intend the generator to run for?  If you are not sure, send a list of what you want to power and a generator specialist, like YorPower who will size the generator for you. If you are still not certain and do not want to write a long list, call us and tell us whether you want the generator for home backup, business backup, temporary power, or something else and we will help you.  The more information you can provide the closer we can match your needs and ensure the right size of generator for you.

Why should I buy a used generator?

When preparing your company for an unexpected event, like a power outage, most businesses often underestimate how useful a fully installed automatic generator would be to assist in maintaining normal operations, let alone how effective a used generator could be to apply.  There are numerous reasons why many businesses do not purchase a standby generator. The majority relate to the cost of purchase. The common belief is that emergency standby generators can only be purchased from new and are expensive. People are unaware that high-quality used generators can be obtained at typically 50% of the price of new. Many used generators on the market have spent most of their lives in backup applications where they have only ever been run for maintenance purposes.Other reasons include:

  • Lower capital outlay – typically half the cost of new
  • Lead time – availability of used generators usually means you can buy and install much quicker than buying new, lead times are usually 60% faster than for a new generator.
  • As a used generator has already been ‘run in’ it should work straight off the bat.
  • Better construction – more often than not an older used generator will be constructed of heavier steel and will be more robust

Are there any regulations that govern emissions?

The straight answer is yes. Diesel generators, specifically for the new, rental and hire sectors, are governed by regulations. If running a generator for Prime power for more than 50 hours per annum, you will have to notify to the governing authority that you are running a diesel engine that falls into the category of MCPD (Medium Combustion Machinery Directive).

Could I be accidentally breaking the law due to current regulations?

Yes. It is fair to say the legislation that deals with diesel generator engine emissions, specifically related to the Diesel Genset Industry is complex, hard to interpret and is fundamentally ahead of engine availability/technology; that is until very recently. This is borne out by various changes sought by industry lobbying groups to delay part(s) of the restrictions on use.  If you’re unsure, please contact us and we can advise.

What is a specified industrial generator?

An individual generator or group of generators if 1) On the same site 2) Operated by the same operator 3) For the same purpose (generating electricity)  If you have more than one generator on your site, aggregate your generators into a specified generator, this requires just one permit. How is your generator affected by MCPD regulation? Firstly, note that your generator can be affected by both MCPD and specified generator guidelines and the permit you will require will depend on this.  Please get in contact with our sales team who would be happy to guide you on the matter.

What type of permit do I need?

Three types of specified generator environmental permit: 1) Standard Rules Permit (low risk) 2) Simple Bespoke Permit (low risk) 3) Complex Bespoke Permit  If unsure contact [email protected]

What else can the user do to mitigate emissions and comply with the legislation?

Fuel quality has changed greatly over the years thereby increasing power output and decreasing its adverse effects on after-treatment devices. Manufacturers continue to look at alternative fuels, innovative fuel systems, and new control strategies to improve the overall efficiency of an engine. Biodiesel has been around for some years, however, it has more recently become a viable option. It is a fuel comprised of methyl/ethyl ester-based oxygenates of fatty acids derived from vegetable oils, animal fats, and typically cooking oils. These fuels are commonly known as Fatty Acid Methyl Esters or FAME. Biofuel / Biodiesel properties are not dissimilar to that of diesel fuel, as opposed to gasoline or gaseous fuels, and so are capable of being used in compression ignition engines such as the diesel engine. Due to certain challenges associated with the fuel (Fuel quality, oxidation stability, contamination, microbe growth, etc), engine manufacturers in the past have been skeptical over the use of 100 percent biodiesel (B100).

Blends of biodiesel with regular diesel are therefore widely used for prime and continuous applications, with B5 and B20 being highly popular in the market depending on the complexity of the engine and the application. The number alongside the letter ‘B’ indicates the percentage of biodiesel in the blend. B5 would have 5 percent biodiesel, B20 would have 20 percent etc. The very latest biodiesel which is commercially available emits lower N0X and S02 than EU Stage V rated engines.
