Renting vs Buying a generator

 Once the sizing of the generator is done, the next big question is whether to buy a new generator or take one on rent. Well, there is no right or wrong answer to this question. In this article, we will discuss the factors to consider before making a decision. After considering all the points, you can decide which one is the most suitable option.

Advantages of renting a generator:-

  •   Renting a generator takes only a fraction of the cost of buying a new genset. If you have a limited budget, then renting is the best option.

  • Rental providers take care of the maintenance and repair of generator throughout the rental period. Therefore, no maintenance hassles and minimum risk of downtime. 

  • It offers the flexibility of generator size. Once a particular project is over a different rating of a generator can be chosen for the next project. 

  • Rental generators are designed as a plug and play option. It does not require detailed installation planning as the permanent installations do.

  • Renting is a good option if the generator is needed for a short duration. If long periods of renting are required, better to calculate the renting cost beforehand. If the total renting cost approaches closer to the purchase cost, then buying will be the better option. 

Advantages of buying a generator:-

  • The prime reason for buying a genset is the need for long term use. Here are the major advantages.
  • You will own the asset and not bind by any rental agreement. You can resell your asset anytime.
  • In large projects where generator requirement is for many months, the rental cost of a big commercial generator will reach the purchase price quickly. Obviously, in such cases, buying may be the right option.

To summarize, a sufficient amount of homework and calculation has to be done before making the decision of buying or renting a generator. Choosing the right vendor is also an important decision to make. Do check the background of the vendor and check the customer feedback. 

Mahindra Powerol is in the business for more than a decade. We can help you in making the decision. For any query, you can call us at 1800-419-1999 or visit our website at:-

Changing Oil Filter in a Diesel genset.

 A diesel genset is a specialized piece of engineering and it needs specialized upkeep and maintenance. And one of the many ways to ensure that it keeps performing to its optimum standards is to change the oil filter regularly. 

The frequency of oil filter change depends on the size of the generator. 

Cleaning the Centrifugal Lubricating Oil Filter 

Before you begin the process of changing the filter, it is recommended that you switch off the engine and allow time for lubricating oil to go back to sump.

   Ø  Remove the cover nut and lift off the filter body cover.

   Ø  Check the "O" ring for damage and change if required. 

   Ø  Remove the rotor assembly from the spindle and wait for the oil to drain from the nozzle before detaching from the filter body. Hold the rotor body firmly and remove the rotor knurled nut. Separate the rotor cover from the rotor body. Remove the central stand tube.

   Ø  Clean the sludge from the inside of the rotor cover with a wooden implement. Make sure it is wiped clean. 

  Ø  Clean and wash out the central stand tube using an approved solvent - make certain that the strainer holes are not blocked.

  Ø  Clean out nozzles with a brass wire to ensure smooth and free passage of oil. Check the top and bottom bearings in the rotor body - they should be free from damage and/or excessive wear and tear. 

  Ø  Completely Reassemble the rotor. Tighten cover nut to 9.5 Nm - 10.8 Nm (7-8 lbft.)

  Ø  Closely check the spindle journals - they shouldn’t be any damage or excessive wear. Then remove the cut-off valve plug from the filters only and the cut-off valve assembly.  Make sure that the spring and shuttle are in good condition and move without any hindrance. Examine the gasket and replace if damaged or worn out. 

  Ø  Re-assemble cut-off valve assembly.

  Ø  Re-assemble the filter fully. It is important to make sure that the rotor assembly is free to rotate. Now, replace the filter cover and tighten the cover nut. 

  Ø  Switch on the engine and with the engine running check all connections and joints for any leakage.

Cleaning Engine Oil and Standard Spin-On Type Lubricating Oil Filters

Switch off the engine and place a container of at least 148 litres capacity (32.5 gal) below the drain plug. 

Now remove the drain plug and allow the oil to drain. 

It is advised that this procedure be best carried out while the engine is still warm - the thinner oil will drain more efficiently. As the oil is draining, remove the three oil filters by turning them clockwise with a strap wrench. 

Wipe the sealing faces and threaded bosses of the oil header. Smear engine oil on the captive rubber sealing ring and carefully screw each new filter using firm hand pressure only.

Refit the drain plug and fill the engine with the appropriate grade of new oil. Manually set the air shut off valves to the run position and hold the stop lever in the stop position. Start and crank the engine over until the oil pressure gauge registers 0.4 kg/cm2 (5lb/in2).

Continue cranking for a further 10 seconds - this will ensure that the oil has reached the turbocharger bearings. Stop cranking the engine and visually check the engine for oil leaks, top up the oil level.

Cleaning the Optional Changeover Lubricating Oil Filters

A three-way change-over valve in the head enables the elements to be changed, one at a time, whilst the engine continues to run. They are normally mounted on the engine, but may be remotely mounted, and connected to the engine by means of flexible pipes.

Changing the Filter Elements without Stopping the Engine

The normal position of the change-over valve is the leg of the inverted T pointing upwards - when both filter elements are in circuit. Turning the tine valve so that the leg of the T points to the left, puts the right hand filter out of service - this lets it be replaced by a new filter. Turning the valve so that the leg points to the right, puts the left hand filter out of service, so that this one can now be exchanged with a new filter canister. The valve is then returned to its original position, so that both elements of the filter are back in service. 

Remember that regularly changing your oil filters in your diesel gensets will prolong its life.

Electric Utilities to thrive in the Electric Vehicle revolution!

There is a global shift taking place towards the choice of fuel for automobiles. From fossil fuels, the choice is shifting to electricity. A strong public sentiment and government initiatives are supporting this shift. All major car makers are coming up with their EV models. Government’s initiatives of Transport Electrification (TE) and infrastructure development is fueling the growth of EVs and made it as one of the fastest growing business segments.

The Automobile Battery is the major contributor to the cost of ownership of an EV. The major focus is on the optimizing the battery cost and charging time. With technological advancement, the cost of the batteries are decreasing steadily. The cost per kWh of an EV battery was $150 to $175 in 2017. It is expected to decline further to $80 to $105 by 2025 and $70 to $90 by 2030. With declining battery cost and increased capacity, the economics of buying an EV becomes more favorable.


To harness business opportunities from this buzzing EV market and the growing TE market, the electric utility companies are busier than ever.
The power demand for charging the EV's are negligible. But the charging grids will face challenges like:

§  Peak hour load management.

§  Discover nearby charging stations.

§  Offer attractive rate plans and offers to customers.

Opportunities lie on the smart and intelligent solution to address the challenges mentioned above. There is also a promising market for infrastructure development to support the government’s plan for Transport Electrification.

Electric Buses, fleets of shared mobility EV's will require highly efficient and professional support for charging and maintenance.

There will be increasing demand for a smart solution for home charging in residential complexes with slow charging during the night and fast charging option in the daytime.

Some innovative concepts like Shared Charging or charging via appointment can be worked upon. Dynamic pricing can encourage customers to charge their EV's during off-peak hours and reduce load during peak hours.  

Electric utilities will immensely benefit from the growing EV market. They will play a major role as service providers and will be partners in building a greener future.

Lessons by a tiny Virus.

A pandemic hits the globe and forces almost all the nations to complete lock down. People are getting infected, hospitals are overloaded, schools are shut, factories are closed, stock markets crashing. It is a panic situation everywhere. This tiny little virus COVID 19 has literally brought the entire human civilization into its knees. The pandemic brutally breaks our ego and tells us that everything is not in our control. This is a humbling experience for the human race.

These are hard times for every nation, but there is a bright side to this as well. The current crisis is uniting the entire humanity in a very strange way. Political differences are forgotten, bilateral issues are ignored, countries are coordinating and helping each other like never before. People are connecting with each other in many amazing ways. Incidents like Italians singing on their balconies, Indians clapping for their COVID fighters – will be etched in our memories forever.

In the times of self-isolation and social distancing we realize the value of society and the people. Thanks to the internet and the gadgets of communication. We are staying connected.

Our everyday routine is shattered. It is time to re-think and re-evaluate our habits. Our weeks used to be loaded with work and many other activities like going to the theater, gym, shopping mall, restaurant, bar, birthday party, festival, concert and many more. Suddenly all these are forbidden, and life still goes on. We are learning to utilize our free time more wisely staying at home with the family. Soon we will realize how many non-essential activities kept us busy for so long.

Companies are also evolving. Work from home has become the new normal, employees are working without much interventions from the superiors. Options for virtual conferencing was present before, but this tiny virus compelled us to use this technology much efficiently. We are forced into an innovation mode. Schools are continuing classes online. Auto drivers turning into delivery agents. Everyone is trying to innovate, it will be interesting to see if the speed of innovation continues after this crisis is over.

How Mahindra group is contributing to the fight against the COVID-19 pandemic:-

Work from Home: How to make it interesting

Every office goer at some point in their lives has thought of working from home. Working from home was considered as a special benefit our kind bosses allowed occasionally. While most software companies had the work from home policy long before the COVID-19 crisis, rest of the organisations were not fully ready for it. The current situation is completely different though, the entire country is under lock down and most of us do not have the option of going to work, until the situation normalizes. Lakhs of employees are working from home for the first time in their lives.

Below is a compilation of some great tips for efficient work from home.

§  Start early: Don't be lazy, get up early freshen up and hit the laptop. Remember, while working from home you are your worst enemy, you don't feel the pressure of getting things done, you may end up doing less. It is even better if you look at your to-do list as soon as you get up.

§  Think that you are going to office: Your mind tends to relax while you are at home, you are used to this for years. This needs to change while you are working from home. Try to do all the things you used to do during office going. We suggest, wear your office clothes.

§  Find a space dedicated to work: Get out of the couch or bed or from all those spaces which you are using for leisure. Dedicate a specific place for work. Remind yourself that you are in work.

§  Don't mess around in Social Media: You know what it is, do we need to explain?

§  Do more than usual: Commit yourself to provide more output than usual. In the office, you may have many distractions like unnecessary coffee breaks, chit chat with colleagues etc. You have a focused time at home, make full use of it.

§  Learn to change modes: While working from home, you may face distraction from your wife, kids, neighbors etc. Use this pressure to stay focused. You may choose to ignore your neighbors but give time to your wife and kids. But quickly get back to work mode.

§  Stay connected: While working from home, you may feel disconnected from the business. Messaging tools, video conference tools make it easy to check with your colleagues. So be in touch.

§  Take a break: Do not overload yourself too much, plan your breaks beforehand and get away from the computer. Use this time to eat your food, make personal calls, and check your social media accounts. These breaks will recharge you and make you more productive.

§  Take special precaution for preventing the Corona virus pandemic: Please ensure that you and your family is following the safety tips.

  • Keep yourself physically fit: Do not sit continuously for long hours. Practice some of the basic yoga poses. Add meditation to your daily routine and witness the power of body, mind and soul coming together.

Generator Control Panel

When you have invested in an asset that is the backup power generator, you also have to invest a little time and effort to ensure that it is performing to the best of its capability. This task is made easier thanks to highly efficient control panels that most generators of this generation are equipped with. They are engineered with a range of monitoring options - starting with auto start and auto stop to the critical “Emergency Shut Off” switch. 

The control panel is linked to several sensors in the generator to keep you updated with all the important information you need. This can include intelligence on system efficiency, voltage, running hours, alarms and display warnings. The Automatic Transfer Switch (ATS) works with the control panel to start the generator the moment power outage is sensed. 

It is important to fully understand and use the control panel to get the maximum bang for your buck. The control panel can protect the generator from low oil pressure, high temperatures coolant fluctuations and dangerous engine speed variants. The control panel can also shield the alternator from circuit break failure and system overloads. Advanced upgrade able panels can even customize automation requirements and alerts and fine tune the intelligence delivered. 

It is vital to consider the levels of control and quality and quantity of information required before choosing the right generator for the application. Critical applications will demand advanced control panel functions and precision automation. If the generator is meant for limited use and is meant for less intensive applications, a less advanced control panel will do the job. Basic information on voltage, amperage, warning lights and alarms are standard features even in simple panels. 

As mentioned earlier the kind of control panel you need will depend on the criticality of the generator’s usage.

Use of clean diesel for your generator

Diesel Generators are robust and very much dependable when maintained properly. Enough has been said about maintenance of a diesel generators. The maintenance programs primarily suggest timely replacement of Lube oil, Coolant, Filters, Gaskets and other worn out parts. These are important, but diesel fuel management is also equally important.

Diesel does not have an unlimited shelf life. Over time it starts to deteriorate. The older generation of diesel engines could run on pretty much anything. With the advancement in diesel technology the chances of failure due to poor diesel quality increased. Modern diesel engines operate at a much higher injection pressure compared to the older generation engines. At very high pressure even a microscopic particle will case accelerated wear and tear to the fuel injection components.

If stored under normal conditions, diesel will have 6 to 12 months of useful life. As the fuel gets older it will be contaminated mainly by three reasons:

1. Water condensation

2. Bacterial growth
3. Solid particulates

The diesel fuel naturally attracts water and it is the biggest enemy of diesel. The water particles present in the diesel will cause corrosion of metallic parts of the fuel system. Contaminated diesel can be supplied by the diesel supplier, condensation could be collected from the air inside the storage tank or rainwater can enter the diesel tank through vent holes. The microbes feed on the hydrocarbons of diesel. The water works as a catalyst allowing the microbial growth. It forms a sludge in the diesel. The sludge can get sucked into the engine and choke the Fuel Filters and damage the Injectors. Solid dirt particles can be present in the diesel from poorly sealed air vents or rusty walls of the fuel tank. These particles will block the Fuel Filter and damage the Injectors.  

The nozzle openings of the Fuel Injectors are extremely precise. They deliver precisely measured quantity of fuel in a well-defined spray pattern. A smallest dirt particle can pose serious threat to these high precision modern Fuel Injectors. Electronically controlled engines will have more precision engineered fuel system components compared to mechanical engines. Dirt particles in the fuel may cause very costly damage. 

There are simple ways to prevent these problems.

  • Always use genuine Fuel Filters prescribed by the engine manufacturer.
  • Follow the maintenance schedule of the filters.
  • Regularly drain water from Water Separator.
  • Buy diesel from reputed suppliers.
  • Always keep the fuel tank full to prevent water condensation from the trapped air.
  • If you are not using the Generator for long time, do consider the shelf life of the diesel.
  • Clean the Fuel Tank once a year. Do not allow any rust formation on the tank.
