INDIAN RAILWAYS GREEN ENERGY INITIATIVES

Energy Conservation on IR

  • Introduction

    • Hon’ble Prime Minister of India, Shri Narendra Modi had stated on December 25, 2014 that:

      “Railways, perhaps along with post offices, are the only two institutions in India with a deep network which if tapped judiciously can create substantial improvements in the hinterland. Railways were always considered only as a mode of transport in our country, we want to see Railways as the backbone of India's economic development.”

      Indian Railways (IR) is a great national asset. A single transport network connects far flung areas of the country. It is one of the largest transportation and logistics network of the world which runs 19,000 trains, passenger and freight put together. It runs 12,000 trains to carry over 23 million passengers per day connecting about 8,500 stations spread across the sub-continent. It is equivalent to moving the entire population of Australia. It runs more than 7,000 freight trains per day carrying about 3 million tonnes of freight every day. Its network of 65,000 route kilometers is more than one and half times the circumference of the earth. It has joined the select club of countries ferrying more than a ‘Billion tonne’ of freight, with other countries as China, Russia and United States with originating freight loading of 1008.09 million tonnes in 2012-13. During 2014-15, Indian Railways is expected to carry more than 1.1 billion tonnes freight.

  • Background

    • Globally, the transport sector consumed 27.6% of global energy use, where liquid fuels are the dominant source. Transportation alone accounts for more than 50 percent of worlds consumption of liquid fuels, and this share is likely to grow to over 60% by 2035. Within the transport sector energy consumption and therefore CO2 emissions are dominated by road, followed by aviation and shipping. 2.2% of this energy is consumed by rail sector, which means that 0.6% of the world’s energy is consumed by railways. This energy usage is categorized for traction power (used to power trains) and for non-traction (used mainly in buildings). Further, Railways are considered as safe, energy efficient & low carbon mode of transport & has a pivotal role not just in the economic progress of any country but is being increasingly viewed as the key player in switching over to a low carbon and sustainable society by attracting passengers from other modes of transport, optimise electrification, incorporating technological innovations & building up capacity and resources.

      a

      The amount of passenger-km transported by rail in the world grew by 130% since 1975. India is the major contributor in this area. The demand for energy in railways is increasing to meet the requirement of the increasing rail traffic. So Implementation of energy efficiency measures in rail transportation is an important agenda in various countries to achieve sustainable rail transportation with the increasing growth in rail traffic.

      Indian Railway (IR) has one of the world's largest rail networks comprising 115,000 km (71,000 mile) of track over a route of 65,436 km (40,660 mile) and 8,495 stations. In 2014-15, IR carried 8.397 billion passengers i.e. more than 23 million passengers a day besides 1050 million tons of freight. By 2015, electrification of tracks on Indian Railways has been extended up to 26,000 km which constitutes around 40% of the total Railway Network.

      As per “Indian Railways Vision Document 2020” IR has plans to achieve the cumulative target of 33,000 km electrification of its existing tracks. This indicates that energy consumption of IR is going to increase substantially in coming years.

      Currently, Indian Railways is putting efforts to implement energy efficiency measures in railways to reduce the reliance on the conventional sources of energy which are getting costlier with rapid growth in their demand while their sources are limited or getting exhausted and to reduce the GHG emissions. Even though rail is more energy efficient than most other transport modes, the enhancement of energy efficiency is an important issue for Indian Railways to reduce their contributions to climate change further as well as to save and enlarge competitive advantages.

  • Indian Railways perspective in energy sector

    • a

      IR accounts for close to 1.8 per cent of the country’s total electricity consumption (IR utilized more than 17.5 billion kilowatt-hour (kWhr) electricity in 2014-15). IR’s energy consumption has been increasing over the years. During the period 2009-14, while the electricity consumption for traction has increased by 20 % for non-traction it increased by 0.16% only. Indian Railways has developed a long-term Energy Efficiency and Conservation Program (EECP) (2010-2032). The Program aims at progressively introducing a number of energy efficient technologies and measures in the railway system. Indian Railways has been taking steps towards energy efficiency and has been reducing its specific electricity consumption by about 3.0 % on year to year basis, in both traction and non-traction areas. However, considering the energy efficiency opportunities available and the upcoming expansion there it is felt that there is immense scope to further improve upon this by adopting and use of innovative energy efficiency technologies, solutions and best international practices.

      Some of the steps earlier initiated by IR, keeping the long term perspective in mind for energy conservation are:

      • Going for three phase Energy Efficient technologies for Electric locomotives and Electrical Multiple units (EMUs)
      • Introduction of energy efficiency measure for non traction uses, like going for LED lights, use of star rated electrical equipment only etc.

      In Indian Railways the average growth in electricity consumption for traction application between years 2007-2008 to 2013-2014 was around 20 % and the rise in electricity cost over this period was 50%. In the same period the freight on electric increased by 41% and passenger traffic increase by 36%.

      a

      It means that with only about 20% extra energy 41% freight growth has been achieved. This has happened due to induction of energy efficient locomotives on IR. This is due t0 improvement in SEC by 17.6% in the same period.

  • Energy Management in the Indian Railways

    • The total Electric Energy bill for IR in the year 2014-15 was about 11000 crores and the Diesel bill was about 18000 crores. Indian railways had been working continuously to improve its energy uses by induction of latest energy efficient technologies. These efforts have been regularly recognized at the National level as many of its establishments have won prestigious National Energy Conservation Awards over the years. It had remained the largest winner of BEE awards year after year. In the last five years it had bagged 64 No. of energy conservation awards. These measures like introduction of three phase Electric locomotive technology, use of power factor correction capacitors at Traction Sub Station TSS, use of T5 lighting, high efficiency pumps, 3* and above rating equipment and various other energy efficiency measures have resulted into a total saving of about 2500 crores in its electricity bill over last 5 years. As per the estimates Railways have been saving more than 400 M Units of electric energy through these means in its Electric Traction and Non Traction energy uses. These measures by Indian Railways have resulted into huge savings of electricity for non-traction applications despite increase in connected load by about 5%. Further to it IR has chalked out an ambitious plan to save on 10-15% energy in next 5 yrs.

      Initiatives for improving the energy utilization on IR:

      i. Energy Audits

      World over it has been recognized that continuously auditing various energy consumption centers in the light of latest technological solutions available for energy saving brings out the potential areas of energy saving and after carrying out A B C analysis of these areas, investment planning be done. Accordingly all Zonal Railways and Production Units have been asked to carry out fresh energy audits on consumption centers of more than 100 KW of electric energy and identify areas having energy saving potential. Railways have been given target to complete analysis for such units using both external and internal means (using our own officers and staff as well). While railways have already starting taking actions on their earlier audits and have started looking for savings across all the establishments based on these earlier audits, however new audits will provide potential areas with respect to latest technological developments and based on these Energy Audits, will take up technology up gradation works. They will also assess the benefits in energy saving on implementation of these new technologies, to decide on expansion of uses of such identified new energy efficiency technologies. Railways through these audits will also identify areas of energy wastage and will devise means of monitoring to avoid such wastages.

      In 2014-15, Railways consumed about 2.5 billion units for non-traction electric power with average cost of power of about Rs. 6.50 per unit. The initial assessments have brought out that on non Traction side lighting consumes about 25-40%, water pumping 30-35%, fans about 15% and air-conditioning about 10-15% energy. Accordingly detailed energy audits will be undertaken in areas like water pumping stations, air conditioning, lighting etc. for assessing energy saving potential.

      ii) Adoption of LED lighting

      With recent advancement in LED lighting technology, which has substantially brought down the prices of LED lights to a level where LED lights have become cost-effective as compared to all other means of lighting, with pay back periods of about 2-3 years and with 5 years warranty, there by reduced maintenance costs, it has been decided by Railways to use only Led lighting in future, in all new establishments and for replacement of old lights in railway offices, stations, street lights etc. A policy directive to this effect was issued by the Ministry on 17th April 2015. Railways probably are the first organization to issue policy directive to use only LED lighting for all its future establishments and for replacements of existing light fitting on completion of their life. Railways are further working to take more policy decision for introduction of energy efficient equipment

      iii) Super- Efficient Ceiling Fans for railway quarters, offices, railway stations

      The super-efficient (SE) fan consumes 35W as compared to the current market average of 60W. The SE fan is also significantly more efficient than the 5 star rated fan (most efficient fan) which consumes about 45- 52 W. In case conventional fans are replaced with super-efficient fans (Brush Less DC motor), there exists an energy saving potential of 30-50%. Looking at the huge use of this appliance in Railways, IR has taken up a pilot project for using SE fans on Northern Railways.

      iv) Energy Management System

      In order to achieve sustained efforts on Energy Efficiency and Fuel Conservation on Indian Railways, all railways units are taking up implementation of ISO: 50001 (Energy Management system). The units which are already certified for ISO: 9001 and ISO: 14000 will take lead in the initial phase, as it would be easier for them to adopt such a standard.

      The ISO 50001 is the International Standard for Energy Management System providing a robust framework for optimising energy efficiency in public and private sector organisations. Certification to this standard demonstrates an organisation’s commitment to continual improvement in energy management, allowing them to lead by example within their respective industries and ensures that related legislative and regulatory requirements are met. The key benefits of certification include:

      • Reduced operating cost - Significant financial savings can be achieved through increased energy conservation
      • Improved energy efficiency- ISO 50001 is the most robust energy management system, enabling to make continual improvements to become as efficient as possible
      • Reduced carbon footprint - It reduces the carbon footprints and people will respond positively to the organisation
      • Legal compliance - Makes understand how statutory and regulatory requirements impact the organisation and stay on the right side of the law
      • Proven business credentials - Independent verification against recognised standards enhances the brand value of the organisation.

  • Major Policy Guideline/Circulars/Manuals on

    • Energy Efficiency:

      IR has been actively taking Policy initiatives by issuing of various Guidelines/ Circulars on General Power Supply Systems like use of LED lights, Star rated equipments etc. Listed below are some of the major Policy Guideline/ Circulars and manual issued for Energy Conservation and energy management in Indian Railways in the recent past:

      • Use of energy efficient LED lights in place of Compact Fluorescent Lamps (CFL) and incandescent lamps (GLS).
      • Directions to carry out energy audit.
      • Development and issue of Energy Audit Manual & Standard Template for Contract Procedure for Energy Audits Services for Indian Railways Installations by RDSO.
      • Use of star labelled products on Railways.
      • Direction to take benefits of DELP scheme for LED bulbs for railway staff.

      Recently IR signed MOUs with Min. of Power and BEE for co-operation to improve Energy Conservation on IR in the presence of Shri Suresh Prabhakar Prabhu, Minister of Railways, Shri Piyush Goyal, Minister of State Independent Charge for Power, Coal and New & Renewable Energy. The main points of the MoU are:

      • Ministry of Power and Ministry of Railways to share knowledge on various developments in the power sector to reduce the cost of power to Railways.
      • Ministry of Railways and Bureau of Energy Efficiency will identify technologies to further improve efficient utilization of Energy on Railways.

      In addition a MOU between Railway Energy Management Company Limited and Energy Efficiency Services Limited for implementation of Energy Conservation projects over Railways was also signed.

      These MoUs, aims to provide a frame work for promoting future solutions and facilitate Railways bring a change in its energy mix. This is also needed looking at the requirement of the present time which wants close co-ordination between stakeholders, working together and understanding each other to make faster deliveries to people. These MoUs will pave for efficient and reliable utilization of resources in the power sector for making it possible for the Railway to take benefits of various developments taking place in the power sector as a whole.

      On this occasion a MoU was also signed between MNRE and Min of Railways. Railways are one of the biggest consumers of power in the country and would like to become leader in the renewable sector and master the technologies leading to efficiency utilization of energy. These 3 MoUs with Ministry of Power (MoP), Ministry of New and Renewable Energy (MNRE) and Bureau of Energy Efficiency (BEE) will take care of complete power sphere from Railways perspective covering generation of power to demand side and make it possible for Government of India to show case how learning from each other can take you ahead in exploiting world class technologies and provide cheaper services to the people at large. These MoUs will also provide Railways the technical expertise, and open training facilities available in the power sector, to Railways.

  • Journey of Energy Conservation on IR:

    • a

      IR had been very conscious about saving energy, as energy saved is energy generated. It started energy conservation journey much earlier and at every satge took the benefit of best available technology, weather it was replacement of T-8 FTL by energy efficient T-5 & CFL fittings, provision of LED lights, energy efficient ceiling fans, occupancy sensors, use of star rated equipments etc. These efforts had earlier resulted into a saving of 1.03% of electricity for non traction application during 2011-12 despite about 5% increase in connected load.

      The National Energy Conservation awards won by Zonal Railways in the past are as under:-

  • Star Rating of Railway Administrative Buildings

    • Buildings in India have energy efficiency potential of 20-30% in terms of energy consumption, Bureau of Energy Efficiency(BEE) has recently started a scheme for star rating of office buildings based on specific energy usages. The scheme rates office buildings earning 1-5 star scale with 5 star label buildings being most efficient. Five categories of building – office buildings, hotels, hospitals, malls and IT parks in five climate zones in the country have been identified for this programme.

      Bureau of Energy Efficiency (BEE) has started endorsing all major office buildings which have connected load of 500 KW or more on Energy Performance Index. The star rating program for buildings would created a demand in the market for energy efficient buildings based on actual performance of the building in terms of specific energy usage. In view to promote energy efficiency Railways have been advised vide Board’s letter under reference(i) to get star rating for all major buildings which have connected load of 500 KW and more from BEE. The following Railway has been star rated by Bureau of Energy Efficiency.

  • ‘5 Star’ rating for ICF, Chennai Administrative Building.

    • Integral Coach Factory (ICF), Chennai Administrative Building has been awarded ‘5 Star’ rating by Bureau of Energy Efficiency (BEE), Ministry of Power, Government of India, on 13th July 2015. The ‘5 star’ rating of this building is the highest rating in the category of ‘Office Building’ instituted by BEE.

      ICF Administrative building comes under the category of ‘air-conditioned building in warm and humid climatic zone’ and this building has achieved energy performance index of 93.85 kWh/sqm/annum, against BEE’s norms of 100 kWh/sqm/annum. ICF has achieved this performance index by adopting effective energy conservation measures and installation of energy efficient equipments in the building. Few of the Energy Conservation Measures (ECMs) adopted are installation of 3 Star and above rating air-conditioners, VRF controlled air-conditioning system, replacement of conventional controls in lifts with VVF controls, provision of occupancy sensors in the chambers and wash rooms, LED lighting, LED facade lighting in place of flood light system.

  • Major measures implemented/ being implemented on the Electric traction side are:

    • Electrical Multiple Units (EMU) -.

      a

      1. 116 energy efficient AC/DC rakes with 3 Phase IGBT type propulsion system have been introduced in Mumbai Suburban area with regenerative braking feature since 2007. In Western Railways the total energy generation of 64 EMU rakes with regenerative braking is 82.6 million KWh per annum and total saving is approx. Rs. 65.39 Crs. per annum. In Central Railway the total energy regeneration of 52 EMU rakes with regenerative braking is 66.7 million KWh per Annum and total saving is Rs. 53.53 Crs. per Annum.

      % increase in 2013-14 w.r.t.2007-08 7.23% 37.23%

      • Increase in traffic in GTKM ------- 37.23%

      • Whereas increase in energy consumption ------- 7.23%

      3.0 It may be noted from the table that 10043.39 million GTKM were hauled by consuming 341 MU in the year 2013-14 whereas 7318.32 Million GTKM of traffic was hauled by consuming 318 MU in the year 2007-08. As per the energy efficiency with the traction system prevailing in the year 2007-2008, 10043.39 Million GTKM would have been hauled by consuming 436 MU. This figure has been achieved by projecting energy consumption of 2007-08 on pro-rata basis to year 2013-14. Actual consumption in the year 2013-14 is 341 MU, thus there is saving of (436 MU - 341 MU) = 95 MU. This implies that there is net saving of 21.71% of energy in the year 2013-14 due to conversion and regenerative braking system of EMU & locos.

      4.0 As per prevailing tariff in Mumbai suburban area, cost of energy is Rs. 6.86 per unit in 2013-14 .

      In view of this now no audit of any TSS is being done thereafter.

      ISO 50001 of buildings and installations:

      ISO 50001 for Energy Management system has been obtained for DRM offices of RJT, BCT, BVP, ADI, ELS - Valsad & for ST station for the first time on Indian Railways. Proposals for obtaining ISO 50001 for 20 other locations are in pipeline.

      iv) Initiative taken leading saving in traction & non traction energy Monitoring of energy regeneration on three phase Electric locomotives through CMS.

      With technology advancement and availability of efficient switching devices, regenerative breaking has come into design with 3 phase GTO locos. A week long drive was launched during Aug-15 to counsel all Loco pilots/Asstt. Loco Pilots for ensuring entry of Energy and train load readings at the time of ' signing Off ' through CMS. These data are being analysed to decide the benchmark in particular section & load wise. During the drive special emphasis has been given to encourage & motivate Loco Pilots for Energy conservation while coasting and efficient use of regenerative breaking for optimization of regeneration in 3-phase locos.

      Saving in Non traction was achieved through number of green energy initiatives like provision Solar power systems on stations, LC gates, provision of Solar street lights in colonies, stations, apart from conventional energy conservation measures like provision of LED fittings on stations, provision of Energy Efficient Light fittings, automation of pumps, provision of star rated equipments, automation of 70% lighting circuits on platforms through signaling system etc. on Western Railways.

      v) Initiatives taken for improving the designs to improve energy utilization.

      1. In Mumbai sub-urban section 1500 V D.C. traction system has been converted to 25 KV AC traction system in various phases which was very tough task looking to the sub-urban traffic and OHE clearances below existing old bridges. Conversion from 1500 V D.C. to 25 KV A.C. system completed on 05.02.2012.

      With 25 KV AC, energy losses in system have been reduced considerably and regeneration with 3 phase technology in EMUs and locos has become possible. About 30 % of energy consumed by EMU is fed back in the system by regeneration since 2012-13. This has resulted in 82.56 MU of energy saving costing Rs. 65.39 in 2014-15.

      2. Other initiatives to reduce losses in system are as under:

      • Periodical current collection tests are being done by OLIVER-G equipment and hard sports are being attended promptly so that no sparking between OHE and panto pan takes place.
      • Checking of OHE by roof mounted thermal imaging camera to detect hot spots in OHE and timely attention so that not only possible breakdown are avoided but energy losses are also eliminated. Similar checking is being done in switching stations and traction substations to avoid overheating.
      • 105 sq mm jumpers are being replaced by 160 sq mm jumper at isolators in first sub sector from feeding end.
      • 1600 Amp capacity isolators are being provided in place of 1250 Amp capacity isolators.
