The market for global captive power plants is expected to be USD XX million at the end of the year 2015 and by the end of 2022 it is expected to reach USD XX million. The market is expected to grow at a rate of XX%. Captive power plants are power plants established by individuals or cooperative society for their own use. Abysmal power availability for critical processes and at premium price is the reason that, organizations are compelled to establish captive power plants to satisfy their needs.
Captive power plants are used in areas where there is requirement for continuous supply of power and the opportunity cost of stoppage of production due to power loss is high. Cement factory, steel plants, chemical plants, textile plants, fertilizer plants and many other industries which require uninterrupted power install in-house power generating systems.
The major drivers of captive power plants are the needs for reliable power supply at reasonable cost. Generally factories are established near to the sourcing point of raw materials or mines. It is not always that there is a power plant in the vicinity. If the distance is more then, the cost of transmission has to be borne by the user along with added expenses due to technical loss during transmission. So the factory owners try to overcome this problem by establishing a power plant dedicated to their factory in the premises. Even though the factory is able to access power from a nearby power plant there is no assurance of reliability of power. In developing countries there is mismatch of demand and supply of power. During peak power demand industry is always the loser due to the demand to supply power to the public. So captive dedicated power source becomes a necessity for the power companies. There are also restraints for the captive power plants. For factories that do not have surplus land near the factory face the difficult problem of land acquisition. With each passing year to increasing land prices, population density this problem is becoming more acute. Also generally the captive power plants have smaller units with the object of supporting the factory. Smaller power plants are not as efficient as their bigger cousins. So there is instances of higher pollution in this captive power plants.
Captive power plants are full scale power plants albeit with smaller capacity. These include components like, heat exchanger, boiler, transformer, turbine, and generator. Captive power plants can run in operate with various sources of power. It can be either conventional sources such that, coal, CNG, diesel based or unconventional sources such that, solar, wind or geothermal based.
The market drivers for captive power plants is the requirement to transport and store hydrogen safely. More the use of hydrogen in industry more is the demand for this compressor. The restraints for this market is that during the process of compression the purity of hydrogen is diluted. Also the compressor consumes a lot of power during its operation.
In a conventional power plant, the fuel is used to heat the water whose steam runs the turbine to generate power. After running the turbine, this heat is wasted. However when this heat can be utilized in cogeneration plant by using it for industrial purpose. This further opportunity for the industries to reduce their cost. Also if the power generation is higher the company can supply surplus power to the grid at spot exchanges and earn additional revenue. However the challenges for these plants include high cost of establishment. Also fluctuation in the fuel prices affects the feasibility of power generated at captive power plants. At times even securing the particular type of fuel becomes challenging due to various reasons.
