Boosting the power sector with turbines

Discussion on turbine industry’s status, growth drivers and offerings

With a total thermal installed capacity of 212 GW (as of May, 2016), India is the world’s fifth largest producer and consumer of electricity. With proven coal reserves of 126 billion tonne (as on 01/04/2014) and natural gas reserve of 1,489 billion cu.m (as on 01/04/2015), thermal power generation remains the most preferred method.

While sharing his views on the status of turbine industry Arun Mote, Executive Director, Triveni Turbine Ltd said, “The global steam turbine market was around 21 GW in 2015 and is projected to increase to 26 GW by 2020. The Indian steam turbine market was around 2.5 GW in 2015 and is projected to reach 3 GW by 2020.”

The turbine industry is doing well and the industry is opting more for efficient products believes Aditya Gandhi, Partner, Nitin Corporation. He says, “The turbine industry is doing well and the primary technology behind turbine application has been very constant for the last 60 years. Today, the industry is opting for more and more efficient machines which operate at higher steam pressures and temperatures. Also the technology trends in the turbine industry have remained constant and the demand depends upon the industrial activity. So, as such, there is no change and substitution of product for turbines.”

Major growth drivers for turbines
Turbines are also playing a major role in boosting the power sector but it is important to know what the major growth drivers for the same are. Mote shares major growth drivers for thermal turbines in India are:

  • Industrial activity expansion to boost demand for electricity.
  • A growing urban & rural population is likely to boost demand for energy.
  • Increasing investments across the value chain in various sectors.
  • Massive generation capacity addition during 2017-22 is being worked out considering the likely generation capacity addition of 101.64 GW during 2012-17 (against a target of 88.5 GW).
  • Major growth drivers for the turbine industry are clarity of policy regarding availability of coal and other raw materials, believes Gandhi. He adds, “To drive the sector, it is essential that the industrial activity increases so the demand for power grows as well as more power plants are installed. Also, clarity in the regulations regarding cogeneration and installation of more cogeneration plants is leading to an increase in the number of installation in this sector. Also, substitution of the low pressure and low temperature and inefficient machines by larger efficient ones is also important for the growth.”

    Offerings and expertise
    Triveni Turbine manufactures and supplies engineered-to-order steam turbines up to 30 MW. With our steam turbines running in over 70 countries and across 18 different industries, we have an installed base of above 12,000 MWe. Triveni also provides after-sales services such as erection and commissioning, periodic overhauling, long term service agreements, spares, comprehensive O&M services and refurbishing. It has the capacity to manufacture over 150 turbines annually. “We deliver steam turbines in the above 30 to 100 MW range through our subsidiary – GE Triveni Limited, a Joint venture with General Electric,” says Mote.

    Triveni offers back-pressure and condensing steam turbines up to 30 MW that work across a wide range of pressure and flow applications. Our standard scope includes supply and commissioning of the steam turbine and its control system, control oil system, lubricating oil system, condensing system (as applicable), gear box, alternator, electrical metering, control and protection system and the ‘turbovisory’ system.

    Usually industrial steam turbines employ either impulse or reaction technology. However, at Triveni we developed hybrid technology steam turbines, which combine the advantages of both impulse and reaction technologies. This combination allows higher efficiency of steam energy recovery with greater operational flexibility, low maintenance cost and slow ageing.
    “We engage with the customer right from project conception and customise the solution to their needs. We also operate as a partner for the life cycle of the turbine through service contracts. We back them up via a service network in domestic and international markets. We offer re-engineering of spares for other turbine makes, and maintain a large spares inventory,” adds Mote.

    On the other hand Nitin Corporation offers a complete solution for new and used turbines both from India and Abroad. Also it is offering high pressure and high temperature efficient machines for both cogeneration and captive power plants.

    Following is the products that Nitin Corporation provides;
    Steam turbine generator sets

    • Condensing type STG sets suitable for operation for standalone power plants, steel plants, sponge iron industries, etc.
    • Extraction condensing type STG sets suitable for operation for industries having a partial requirement of steam for their process requirements such as paper mills, chemical units, sugar factories, etc.
    • Back pressure, exhaust pressure, type STG sets suitable for operation for industries which require the entire steam for process at low pressure such as paper mills, rice mills, sugar mills, khandsari units, etc.
    • Used, new spare parts for steam turbine generator sets for various makes.
    • Products ranging from 300 kW to 50000 kW.
