Reducing Energy Consumption on Indian Railways : Key Initiatives and Opportunities

Energy conservation activities on IR have led to a saving of about Rs. 2600 crores in last 5 years in Electric Traction

• It has reduced consumption by > 3.3 % on yr to yr in Electric Traction

• By about 2% in non traction despite a growth in load by 5%

• With PAT scheme in force the industry has achieved savings of about 1.3 % per yr from 2012-15.

• No other organization has matched the performance of Railways

• Bagged 64 National Energy Conservation Awards in the last 5 years, with 22 “Awards” in 2013, highest by any single org.

• Appreciate these works in the light of financial crunch and challenges of Governmental systems

• Development of web based software ‘Rail Saver’ for energy conservation.

Actions initiated earlier • Introduction of 3 Phase technology in Electric

Locos and Electric Multiple Units • On date out of about 5000 locos, 800 are

three phase based.• Further improve the 3 phase technology -

Going for IGBT based system from GTO• Improving Driving techniques in use of

regenerative braking• Use of power factor improving techniques. • Use of high efficiency transformers• Segregating of lighting circuits at platforms • Use of energy efficient CFL & T-5 luminaries.

What is next for an Org which pays 12000cr as electric bill (Consumes 17 Billion units) and has real Electricity consumption growth of about 7%

Growth of Traction Bill for Indian Railways

8

Vision of Hon’ble Minister of Railways

Power bill can be Reduced substantially using market forces

Railways to lead in Reducing Carbon footprints

Actions initiated to achieve this Vision

1. Further Improve Power utilization

2.Migrate from DISCOMs to GENCO

3. Go for Renewable Energy

Improve Power utilization - Strategy

• Introduction of latest technology in Traction and non Traction

• Use of Retrofit systems• Arrest leakages • Develop manpower skills • Closely work with the Industry to

develop innovative solutions• Develop IT based analysis tools• Develop investment management and

financing systems• Work on Energy policy development

Improve Power utilization - What is being done

• Switching to 100% production of three phase locomotives from next year and

• Progressively do the same for EMUs• Provide Training to loco pilots on Simulator• Analysis and monitoring of energy

consumption through Rail saver - a web portal• Retro-fitment of LED lights in Railway coaches • Optimal light control system at various

locations

Improve Power utilization - What is being done

• Implementation of SCADA system for major power supply systems

• Automation of pumping installations• Use of LED lighting• Procure star rating equipment- 3 star and

above• Energy auditing of major load centers. • Use of timers for high mast lighting and

sensors in offices• Going for Solar water heating system

LED Lights in EMUs

LED lights have been provided at stations

LED lights at Palanpur station

LED lights at Makarpura station

Improve Power utilization - Future Plans

• Switch to 100% three phase EMUs• Procure Train Sets • Go for High Horse power locos- 9000/

12000HP• Use of LED lighting only • Switch to 5 star equipment • Use Building management system extensively• Go for ECBC Compliant Buildings• Have new energy efficient designs for Railway

stations using renewal energy

Improve Power utilization - Future Plans

• Automate Train Operation- Optimize train operations - Pass trains can save up to 10% whereas the Freight trains up to 30 %

• Install Smart sense & smart Grid system• Switch to 100% Automatic light & fan control • Opt for SCADA system for major installations• Use of super efficient ceiling fans• Go for 2*25 KV system

INITIATIVES TO REDUCE ELECTRIC TRACTION BILL

Power trading: • Pilot project to procure electricity through

Exchange initiated in Haryana• Ground work for trading done in many other

Railways CR,WR, NR, SER, WCR etc.

Power through short term PPAs:

50 MW power of NTPC in NCR replaced through bilateral PPA - saving about Rs. 140 Cr. in a yr.

MEASURE TO REDUCE ELECTRIC TRACTION BILL

MEDIUM TERM

• Procurement of power through bi-lateral arrangement- PPA for 100 MW power signed with GUVNL

• 500 MW allocated from RGPPL• Procurement through Tenders: commercial

bids for 50 MW power from market opened • Technical bids for about 1000 MW called

MEASURE TO REDUCE ELECTRIC TRACTION BILL

LONG TERM - Dedicated Transmission lines with captive power plants:

• Work on Transmission corridors – Kanpur - Allahabad –Mughalsarai in progress

• Work for Transmission line from Sahibabad to Diwana is under progress

• Blue print for a 5000 Km transmission network in progress

Renewable Energy-Use Solar/Wind Power Potentials

AIMs: •To reduced the cost of Power for Railways

•Climate proofing of energy infrastructure

•Use Railway rooftop and land spaces

• Explore new potential areas- Railway land parallel to Tracks

Harnessing of renewable energy

• 10.5 MW wind plant installed in 2009 for ICF• Tender in progress for 10.5 MW wind plant SR• 25 Mw Wind plant will be ready in Oct 2015.• Tenders for 137 MW more will be issued soon• 10.085 MWp solar plants installed : With 1

MWp on roof of Katra railway station• Work on 6.5 MW solar units in progress• Will float tenders for 50 MW Solar units on

Roof Top soon

One MW Solar Plant at Katra Largest rooftop

plant in the IR

• About 3500 PV panels

• Power fed through local grid to all railway installation

Harnessing of renewable energy – Solar – Future Plans

Target to put up 1000 MW Solar plants up to 2019.

• 200 MW through VGF from MNRE under PSU scheme

• 250 MW by REMC through open bidding• 450 MW more on roof top and vacant

Railway land

Harnessing renewable energy - New Areas-

Solar Panels on the roof top of a coachUsing railway land parallel to tracks

Future Power need Scenario- 2032By 2032 – • With over 80% electrification, • 7000 RKm DFC network, • some new high speed (350 Kmph) corridors, • Numberof tracks at 160 to 200 Kmph &• Loading of > 4 billion MT (as per National

Transport Development Policy Committee)• Power requirement to go from 4000 MW to

15000 MW.

Future Scenario- 2032For sustainable growth • Power to be available at a competitive cost• Ensuring reliability - Railways to have its

transmission network of 10000 km &• Captive power plant for about 5000 MW- • Renewable generation of 3000- 5000 MW • With a judicious mix of renewable and

thermal power.

Renewals- Opportunities / Challenges ahead

• Assess potential sites • Developing technically feasible model as per Types of roofs, Land Patches- variable in Sizes• Address connectivity issues at 25 KV • Develop single phase inverters issue• Develop Railway specific designs- vibrations, security • Handle financing issues

Renewals- Opportunities / Challenges ahead

• Speedily implementation• Innovative solutions for Railway environment• Tackle issues of Obsolescence• Club initiative / innovation in the Governmental

environment• Remain competitive• Make available easy financing• Bring a cultural shift

Key opportunities

• Provide innovative solutions for energy saving• Develop energy consciousness in Staff - Training

for all• Leverage information technology to bring

cultural shift• Leverage technology to empower the customer• Introduce life cycle based costing

We will have to think Differently
