Caterpillar, the leading international brand in the world's power industry is represented by allied engineering & services ltd since 1976.
Allied, an emerging six sigma Pakistani organization, known for customer loyalty and complete power solution provider focuses to offer reciprocating diesel, HFO and gas engines applications in electric power generation, petroleum industrial, gas compression, locomotives and marine segment.
Allied also earned its reputation through unmatched quality and performance of caterpillar earthmoving machines and fork lifters. Allied engineering diversified its business lines to emerge as one company known for multitude of solutions.
Global competition and world energy crisis is driving industrial and commercial managers to reevaluate every aspect of their process efficiency.
Pakistan is suffering from energy deficit and there is a need to improve the process efficiencies and get the most out of existing infrastructure.
The energy crisis in Pakistan has turned into a serious situation. The energy crisis in Pakistan can be classified into two categories (i) production (ii) consumption. First of all, we have to give attention to our energy resources, which include indigenous fuel such as natural gas and coal and many other alternative sources of energy including but not limited to biogas, digester gas, solar and wind. It is the duty of the consumer to utilize and consume these forms of energy in an efficient manner. This practice will not only cut the burden from power generation companies but also prove economical to the consumer itself, in the end. Energy conservation has never been an essential requirement for a Pakistani consumer as it happens to be today.
There are too many talks about rental power plants in Pakistan. Keeping the present scenario in view, both big rental power plants and small mobile rental plants are a short-term answer to the present power deficit. In our point of view, instead of preferring these rental plants government should focus on those existing healthy or sick industrial units which can provide extra electricity to national grid. Presently government enters into any deal if you have extra 10mw plus production. This policy should be more flexible and should rely on distributed generation concept and focus on small power producers exporting their excess power to national grid, thereby optimizing the efficiencies of small power plants and bridging the energy deficit with the existing power infrastructure. We have many examples in this regard, where we know that foreign governments even buy 500 kilowatt of electrical units to save their nationals from the menace of load-shedding. Meanwhile, government should establish power generating projects through alternative means including coal, landfill gas, digester gas, wind and solar energy. These alternative energy projects would cater the industrial need and national grid would not have to bear the extra burden.
Our company holds a big-share in alternative energy generation. to mention, landfill applications, agricultural biogas, coal mine methane, coal bed methane, digester gas, bio-diesel, and so on. You will find caterpillar participation everywhere in the alternative energy production projects. Alternative energy generation projects, in general, are much capital intensive and impracticable without governmental fiscal help. Many countries like USA, Germany, China, India, and Thailand facilitate the investors in funding these projects. The initial capital-cost in these projects are very high, by that reason they eventually end up with longer payback time, and that's why governments even have to subsidize their taxes for the economical viability of these projects. Furthermore, government not only invests in these projects but also enters into special agreement regarding power purchasing.
Allied engineering holds lion share in power generation sector. The company is serving the industrial and domestic consumers since 34 years. Our customer-centric approach with one-window solution is differentiating us from our competitors. We have also diversified our business line and widened our products range. We also render 24/7 service facility to industrial and domestic consumers with our dexterous engineers, and technical staff. We are regularly relying on the voice of our customers for continuous improvement. We are among the few companies in Pakistan which follow sigma six business process improvement methodology. Continuous improvement through six sigma becomes a way of life at allied which is made possible through investing on human resource and transforming them to six sigma black belt and green belts. These reasons kept our company always on the higher level and we managed to fetch a fair share from the market.
Our vision is "to profitably grow our business by successfully pursuing strategies that capitalize and leverage on our core business strengths. Our mission is continuous improvement as a way of life at allied."
We focus on our long term goals of customer satisfaction, competitive advantage, employee development and superior business results.
Allied engineering services limited has introduced the caterpillar ups with flywheel technology in Pakistan.
Industrial consumers are the mainstay of the economy. The country's output growth directly attached with their production capacity, so if they face any minute shortfall in power supply or face power quality issues, it will hurt their productivity in a big way. These power surges and frequent failures also kick the company's maintenance cost up and company's bottom line would slide into the red.
An array of automated equipment is now common place on the factory floor, public and commercial places. It has been long recognized that some processes cannot tolerate a power disturbance without loss of a batch or run of material. To save from this production-loss, customer needs "no-break power supply". In this competitive era where automation enhances the productivity level with the introduction of special AC/DC drives, most customer want special quality-power to maintain their products quality. To cater their demand caterpillar offers high-quality diesel generator and uninterrupted power supply (ups) based on flywheel technology.
This mechanism is designed in such a way that following the system integration approach its ups is attached to caterpillar diesel generator set, and whenever there is an outage of electricity, the ups keep supplying the power for another 15 seconds, meanwhile caterpillar generator automatically get started and takes the power-load in this way, the end-user without having power-failure keeps his production line busy.
This system helps in improving the power continuity and availability thus enhancing the production output which ultimately aid in improving Pakistan's economy.
Recently, we have supplied this system to a multinational packaging company. The system includes stand-by generator sets, line-interactive flywheel ups. The main feature of this system is that ups are without batteries.
The paradigm of requiring 15 minutes of battery backup for ups system reliability is an antiquated and flawed perception. When properly integrated, standby generators can and will reliably take load in 10 seconds or less. This eliminates the need for lead acid batteries and extended back up time.
These flywheel-type ups have typically 15 second backup time as minimum and can be extended to 30 sec, which is enough to start the diesel generator and take the complete load.
This system can be usefully applied to health care centers and hospitals, data communication centres, banks, airports, packaging, food, commercial buildings and many other process industries which cannot afford the power disturbance even for a second.
This ups-caterpillar-generator integrated system is the best answer to all those difficulties which the industrial and commercial consumers are facing today due to power shortage.
