Indian Railways implements comprehensive energy conservation policy

Summarize with:

New Delhi: Indian Railways (IR) has introduced a policy aimed at reducing energy consumption and enhancing energy efficiency. The policy includes various measures focusing on sustainable infrastructure, cloud-based data monitoring and management portal, and the deployment of energy-efficient equipment.

The key highlights of the initiatives include:

IGBT-Based Propulsion System: IR has incorporated Insulated-Gate Bipolar Transistor (IGBT) based 3-phase propulsion systems with regenerative braking in Electrical Multiple Unit (EMU) trains, Mainline Electrical Multiple Unit (MEMU), Kolkata Metro rakes, and Vande Bharat Trains.
Energy-Efficient Locomotives: Production Units have transitioned to manufacture energy-efficient three-phase electric locomotives equipped with regenerative braking features.
LED Lighting Implementation: LED lighting has been installed in various railway installations, including stations, service buildings, residential quarters, coaches, EMUs/MEMUs.
BLDC Motor Fans: Brushless Direct Current (BLDC) motor fans are being utilised in coaches and buildings.
HOG System Implementation: The conversion of End on Generation (EOG) trains into Head on Generation (HOG) systems is underway, aiming to reduce diesel fuel consumption, noise, and air pollution.
Energy-Saving Training: Locomotive pilots undergo training focused on energy and fuel conservation during their initial and promotional training. Refresher courses are also provided to achieve better energy and fuel efficiency through improved driving techniques and road learning.
Software-Controlled Energy Saving Mode: Guidelines have been issued for implementing an energy-saving mode on three-phase locomotives. This involves the use of software logic to switch off power supply to specific components, such as Oil Cooling Blower (OCB), Traction Motor Blower (TMB), and Scavenge Traction Motor Blower (ScTMB).
Timely Locomotive Shutdown: Strategic shutdown of trailing locomotives in Multi Units (MU) hauling light loads.
Innovative Power Supply: Introduction of a 750V external power supply at washing/sick lines for maintenance and testing of LHB coaches.
Power Factor Control and Lighting Management: Implementation of Automatic Power Factor Controller panels in High Tension/Low Tension panels and the use of automatic platform lighting management systems at stations according to train services/passenger requirements.
Capacitor Banks Installation: Installation of capacitor banks in traction substations to maintain near unity power factor for energy conservation.
Timer Integration: Integration of timers on high mast tower lightings, street lighting, and circulating areas of Railway stations.
Solar Geysers: Traditional geysers are being replaced with solar geysers, promoting sustainable energy practices.
