India’s first solar powered DEMU train launched

Indian Railways has launched India’s first solar powered diesel multiple unit (DEMU) broad gauge train. It is 1600 Horse Power (HP) train with all solar powered coaches.

The train will run from Sarai Rohilla in Delhi to Farukh Nagar in Haryana. It will replace an existing non-solar powered rake on the same route.

Key Facts

The solar powered DEMU train has six trailer coaches, with 16 solar panels of 300 watts fitted in each of them. These solar panels have been manufactured under ‘Make in India’ initiative. The energy generated by these solar panels will be stored in batteries and will be used during the night.

Benefits

The solar energy system fitted in the DEMU train would result in the saving of 5.25 lakh litres of diesel per train over a life time of 25 years. It will also help in reducing carbon dioxide (CO2) of almost 9 tonnes per coach, per annum and 1350 tons of CO2 per train over a life time of 25 years.

NTPC installs India’s largest Floating Solar PV Plant in Kerala

State-run NTPC (National Thermal Power Corporation Limited) has installed India’s largest floating solar photovoltaic (PV) plant at Rajiv Gandhi Combined Cycle Power Plant (RGCCPP) at Kayamkulam in Kerala.

The 100 kWp (kilowatt peak) floating solar PV plant has been indigenously developed as a part of Union Government flagship ‘Make In India’ initiative.

Key Facts
  • It has been indigenously developed by NETRA (NTPC Energy Technology Research Alliance), R&D arm of NTPC, in collaboration with Central Institute of Plastic Engineering & Technology (CIPET), Chennai.
  • The system was installed by Chennai based Swelect Energy Systems Ltd with support from NETRA and NTPC Kayamkulam station in a short span of 22 days.
  • Floating solar PV systems are fast emerging as an alternative to conventional ground mounted PV systems which are land intensive. It can also be installed on saline water environment.
  • It has various benefits like conserving water through reduction of evaporation, increased power generation due to cooling effect on the panels, reduced installation time etc.
  • Installation potential of such type of floating systems in India is huge because of abundance of water bodies.Particularly in Kerala this type of system has a great potential due to availability of water bodies and lack of presence of enough land.

About National Thermal Power Corporation Limited (NTPC)

  • NTPC limited is a Central Public Sector Undertaking (CPSU), operational under the Ministry of Power. It is India’s largest power generator and accounts for 25% of total electricity generated in the country
  • It was established in 1975 by Union Government which now holds 70% of its equity shares as of May 2015 (after divestment of its stake in 2004, 2010, 2013, and 2015).
  • Its headquarters are located in New Delhi.
