There are numerous reasons for individuals or businesses to own their own backup/standby, prime, or continuous power supply generators in Sri Lanka . Generators provide an added level of insurance to your daily routine or business operations ensuring uninterrupted power supply ( The inconvenience of a power outage is rarely noticed until you are the victim of an untimely power loss or disruption as sri lankan power grid is not much reliable other than colombo surburbs. 

Back-up Power for Individual Residences in Sri Lanka

Individuals can avoid the inconvenience of power outages by purchasing a small backup generator.  Electricity is essential to maintain properly functioning lighting, electronic entertainment equipment, household appliances, HVAC, and security systems. The inconvenience of losing power may not be realized in your pocket book but rather in the safety and well-being of your family.

Houses and small residences only require a small amount of backup power, typically in the neighborhood of 5-10 kW.  These gensets can typically be purchased for less than 1.2 Million LKR. Obviously large residences (> 6,000 sq. ft.) may require a bit more power, which will increase the cost slightly, but still is highly affordable considering the benefits of owning your own power supply.

Emergency/Standby Power for Businesses


As a business owner, a back up power Generator provides an added level of insurance to keep your operation running smoothly without interruption. Luckily, the decision to purchase a generator is easily made by performing some basic financial calculations:

  • First, you must determine how much money your business generates on a daily basis. Only consider the revenue that is strictly dependent on power supply (i.e. phones, computers, process equipment, etc.).
  • Next, factor in any capital equipment or assets that depend on a power supply in order to maintain its value (i.e. perishable goods, etc.) You must also consider costs that are associated with a start-up or shut-down of a process or manufacturing line.  Costly startups and shutdowns due to power outages can prove to be very costly.
  • Finally, add up all of these costs and multiply it by the number of power outages you have each year. This will give you your yearly operating losses due to power disruptions.  Dividing the cost of the generator by these potential losses will determine how many years it would take for the generator to essentially pay for itself.

Costs alone should not be the driving factor in purchasing an electric power genset. Another advantage to having a localized backup power supply is to provide a consistent power supply to your business. Generators can provide protection against voltage fluctuations in the power grid can protect sensitive computer and other capital equipment from unexpected failure. These expensive company assets require consistent power quality in order to function properly. Prime Power Generators also allow for end users, not the power companies, to control and provide a consistent power supply to their equipment.

End users also benefit from the ability to hedge against highly volatile market conditions. When operating in a time-of-use based pricing situation this could prove to be a huge competitive advantage. During times of high power pricing, end users can switch the power source to their standby diesel or Natural Gas Generator  for more economical power.

Prime and Continuous Power Supplies

Other individual and business facilities require continual or constant power supply for long periods of time in remote locations.  This is where generators are depended on to provide necessary prime or continuous power in many applications. Prime and continuous power supplies are often used in remote or developing areas of the world where there is no utility service, where available service is very expensive or unreliable, or where customers just simply choose to self-generate their primary power supply.

Prime power is defined as a power supply that supplies power for 8-12 hours a day.  This is typical for businesses such as remote mining operations that require a remote power supply during shifts. Continuous power supply refers to power that must be continually supplied throughout a 24 hour day. An example of this would be a desolate city in the remote parts of a country or continent that is not connected to an available power grid. Maldivies  is a prime example of where power generators are used to provide continuous power for the residents of an island.

Electric power generators have a wide variety of uses throughout the world for individuals and businesses. They can provide many functions beyond just supplying backup power in case of emergencies.  Prime and continuous power supplies are needed in remote areas of the world where the power grid does not extend to or where power from the grid is unreliable.

A wide range of new and used generators are available to potential buyers in the market today in Sri Lanka . The buying cycle typically starts out with identifying a need (i.e. to power heavy equipment, provide emergency backup, prime or standby power, etc.), then performing research and analysis to determine what your specifications and requirements are.  After that, you are usually faced with the all-important decision of whether to go with a new or used engine and/or generator.  In order to reach an educated decision and an answer to that, a number of factors must be taken into account, many of which are listed throughout this article.

New Generators

Just as it is when purchasing a new car, the number one reason for buying a brand nee generator in sri lanka  is the fact that it comes with a standard manufacturer’s warranty.  The length and terms of each warranty varies greatly but is typically between one and two years, depending on the intended usage of the generator and/or engine.  However, as it is with cars as well, those warranties do not come without a substantial increase in cost.  And, depending on the size, make and manufacturer, there may be a long wait time or limited availability so extra time is often required to account for that, especially on the larger generators.  For companies who have the time to wait and really want the security a warranty offers for a year or two, new generators can be the best way to go.  As it is with any heavy equipment, you simply need to weigh all the pros and cons of your particular situation to determine what the best option is for your needs.

Used Generators
While they do not usually come with a warranty, it is often extremely advantageous to buy rebuilt diesel engines and used electric power generators for a number of reasons. A key one is of course that used generators with low hours on the engines are often available at very attractive prices, and are substantially below the high retail prices of new units.  It’s even possible to save up to 50% or more by getting a low-hour used generator instead of a new one.       

Another key benefit to purchasing a  used Generator in Sri Lanka is it  can be bought and installed very quickly.  There is no waiting because of limited availability and factory lead times, you simply buy it and have it shipped right then and there.  Many sellers will even include shipping in the cost of the unit.   

Also, because most name brand manufacturers build industrial strength equipment, the risk is negligible.  Power generators are built to last and work whenever necessary, as that is their true function in most cases, to always be there when you need them most (as in an outage).  And, depending on the age of the unit, it may even still come with a warranty, or at least a guarantee of some type from the dealer.  Whenever possible, finding a generator that was previously only used for emergency backup or standby power is the way to go.  Backup generators are only run when the prime power goes down so many of these are hardly used at all and have a long maintenance free life ahead of them still. 

The only real disadvantage of purchasing a used generator is just that, it was owned and used by someone else.  Therefore, you most likely have to go on the word of the seller as to the previous usage, history, and current condition the generator and engine are in.  This is why it’s important you always consider purchasing from a reputable company who has the technical expertise and infrastructure to properly test, repair and/or rebuild these large industrial machines.  Most established sellers will test all their used generators for various loads, but many small brokers and individuals simply do not have the appropriate resources at their disposal.  Testing and servicing are both obviously critical.  Most tests often come with a verification certificate that details each units functioning.  Low-hour used diesel generators ranging in size from 35 kW to 2 MW are often readily available. Low-hour indicates that the generator has been in operation for a reasonably low number of hours. Prices obviously vary greatly based on the kW, HP, hours, manufacturer, KVA, etc., Prime being of the Leading generator service companies in Sri Lanka & one of the Leading Generator Suppliers in Sri Lanka , You can rely on us for your Generator requirements in Sri Lanka.


How Does a Diesel Engine Work?

In today’s world, where fuel prices are increasing as a consequence of spiraling demand and diminishing supply, you need to choose a cost-effective fuel to meet your needs. Thanks to the invention of Rudolph Diesel, the diesel engine has proved to be extremely efficient and cost effective.

Diesel fuel is priced moderately higher than gasoline, but diesel has a higher energy density, i.e. more energy can be extracted from diesel as compared with the same volume of gasoline. Therefore, diesel engines in automobiles provide higher mileage, making it an obvious choice for heavy-duty transportation and equipment. Diesel is heavier and oilier compared with gasoline and has a boiling point higher than that of water.  And diesel engines are attracting greater attention due to higher efficiency and cost effectiveness.

The distinction lies in the type of ignition.  While gasoline engines operate on spark ignition, diesel engines employ compression – ignition for igniting the fuel. In the latter, air is drawn into the engine and subjected to high compression that heats it up.

This results in a very high temperature in the engine, much higher than the temperature attained in a gasoline engine. At peak temperature and pressure, diesel that is let into the engine ignites on account of the extreme temperature.

In a diesel engine, air and the fuel are infused into the engine at different stages, as opposed to a gas engine where a mixture of air and gas are introduced. Fuel is injected into the diesel engine using an injector whereas in a gasoline engine, a carburetor is used for this purpose. In a gasoline engine, fuel and air are sent into the engine together, and then compressed. The air and fuel mixture limits fuel compression, and hence the overall efficiency.

A diesel engine compresses only air, and the ratio can be much higher. A diesel engine compresses at the ratio of 14:1 up to 25:1, whereas in a gasoline engine the compression ratio is between 8:1 and 12:1. After combustion, the combustion by-products are removed from the engine through the exhaust.

For starting during cold months extra heat is provided through ‘glow plugs’. Diesel engines can either be two cycle or four cycle and are chosen depending on mode of operation. Air-cooled and liquid-cooled engines are the variants to be chosen appropriately.  It is preferable to use a liquid-cooled generator as it is quiet in operation and has evenly controlled temperature.

Advantages of a Diesel Engine

The diesel engine is much more efficient and preferable as compared with gasoline engine due to the following reasons:

  • Modern diesel engines have overcome disadvantages of earlier models of higher noise and maintenance costs.  They are now quiet and require less maintenance as compared with gas engines of similar size
  • They are more rugged and reliable
  • There is no sparking as the fuel auto-ignites. The absence of spark-plugs or spark wires lowers maintenance costs
  • Fuel cost per Kilowatt produced is thirty to fifty percent lower than that of gas engines
  • An 1800 rpm water cooled diesel unit operates for 12,000 to 30,000 hours before any major maintenance is necessary. An 1800 rpm water cooled gas unit usually operates for 6000-10,000 hours before it needs servicing
  • Gas units burn hotter than diesel units, and hence they have a significantly shorter life compared with diesel units

Applications & Uses for Diesel Engines

Diesel engines are commonly used as mechanical engines, power generators and in mobile drives. They find wide spread use in locomotives, construction equipment, automobiles, and countless industrial applications. Their realm extends to almost all industries and can be observed on a daily basis if you were to look under the hood of everything you pass by.

Industrial diesel engines and diesel-powered generators have construction, marine, mining, hospital, forestry, telecommunications, underground, and agricultural applications, just to name a few. Power generation for prime or standby backup power is the major application of today’s diesel generators.  Check out our article on the various types of engines and generators and their common applications for more examples.

Power Generators

Diesel powered generators, or electrical generator sets, are used in countless industrial and commercial establishments. The generators can be used for small loads, such as in homes, as well as for larger loads like industrial plants, hospitals, and commercial buildings. They can either be prime power sources or standby/back-up power sources.

They are available in various specifications and sizes.  Diesel generator sets rating 5-30 kW are typically used in simple home and personal applications like recreational vehicles.  Industrial applications cover a wider spectrum of power ratings (from 30 kW to 6 Megawatts) and are used in numerous industries throughout the globe. For home use, single-phase power generators are sufficient. Three-phase power generators are primarily used for industrial purposes.
