Electrified Transportation - The Step towards Future: Key Note Speech Eng. Shavindranath Fernando

In 1979 when I joined CEB I was attached to Kelanitissa Power station and the Pettah power station was looked after by our staff.  There were several outgoing feeders from this power station allocated for the tram lines and trolley bus service as the Pettah Power station was primarily put up in 1902 for the Colombo Electric Tramways and Lighting Company. So here we are re opening the topic of electrification of our transport system once again more than half a century after the electrified transport system that we had Colombo operated by the Colombo Municipality was scraped. It defies me to find the reasons for these decisions as I was told by none other than Mr. H S Subasinghe former General Manager of CEB and the first Chairman of LECO, they had to canvass the tea factories during the same period to electrify their own factories scrapping the large number of mini hydro power stations that were powering them. So it is not uncommon for Sri Lankans to do one thing in one hand and undo it at the same time from the other.

In 1983, I was involved in doing some work in the energy sector and I had to analyse the CEB load profile and the demand projections. To my surprise there was an electricity demand component for railway electrification, 32 years later we are still talking about railway electrification. Railway electrification was first proposed by none other than one of our great visionary engineer D J Wimalasurendra somewhere in the early 1920s.

 

When I was small we had green colored electric trolley buses silently moving in Pettah and Fort with their characteristic horn. My grandmother used to talk about the tram cars. The rail lines laid in the middle of the roads in Colombo were still visible until recently. These tram cars were taken off the roads I believe in 1959 or so and the trolley buses too were taken off in 1964. I believe the decision to scrap them were made due to mismanagement, unionism and politics at that time and may not necessarily be for economic reasons.

 

In 1992, we in Sri Lanka Energy Managers Association organized a roundtable on transportation, I organized this event with the experts at that time, late John Diandas, Dr. Jayawardane, Prof KKYW Perera and few others including DIG (Traffic ) Mr. Perimpanayagam as main contributors. It was a very successful one at that time and some SLEMA members made even slide presentations that led to immediate leveling of some road humps that were put up near the pedestrian crossings of the universities, when everyone realized university students were not Montessori students!! Then few bus bays were also constructed on Galle road, though at that time late Mr. John Diandas was against this concept where he argued the busses should stop on the main road while private vehicles should veer away from the main line traffic giving priority to buses. I don’t think this will ever happen though it has a very rational base, perhaps until all of us travel in buses. Once again last year too SLEMA had its annual sessions dedicated for sustainable transportation.

Then in 2008 the Institution of Engineers Sri Lanka sponsored a study of railway electrification and we even got the assistance from the Institution of Engineers India to send an expert in railway electrification and I am sure Tilak who was involved in the study will dwell on. The study had very clear conclusions and a cabinet paper was drafted by the Ministry of Power and Energy and our minister at that time none other than our chief Guest signed it and sent it to the Ministry of Transport which I believe is still there to be signed by the Minister! This cabinet paper never saw the light of the day.

These are some of the attempts made by the professionals of this country to address the efficiency improvements in the transport sector. I must admit unlike in other sectors nothing much has happened in the electrification of the transport sector though it seems to be the obvious solution to many problems in this sector. I am sure those who are involved in this sector know only too well why nothing rational can be done. I do not want to go into details as they are bound to come up in the later discussion session.

So it is very opportune to talk about this topic today and I congratulate EESOC for taking the initiative.

Coming to the topic of the day, it is timely and opportune to take up this matter as a priority due to more than one reason.

• For quite some time hybrid cars are now sought after by many car users and there is very little effort to track down the energy efficiency of these cars and come out with a policy to encourage them and to see the possibility of off line supplementary charging if it can be done or if it need to be encouraged.
• For at least 10 years electric cars have been imported by enthusiasts and not really as a need, to be introduced especially for urbane commuting, for which in my own mind has a tremendous advantage of not only the efficiency gains in running on congested urbane roads but also as a measure to reduce urbane pollution from fossil fuel powered vehicles. With the current tax reductions for importation of such vehicles, it is imperative that we all in the transport and energy sector get together and address the myriad of issues that necessarily will have to be addressed as a matter of urgency.
• We also have to at the same time see the validity of imposition of increase of custom duty on hybrid vehicles in the light of the argument that it favors the electric cars, of which I am not quite convinced if it had been done with this object in mind or the real reason is something else. So I leave it to the experts to argue this out.
• The CEB has an installed capacity of around 4000MW with 900 MW of base load capacity in coal power plants and a maximum demand of nearly 2000 MW. This excess capacity can be used to meet the requirement of the transportation sector.  The load factor of the system which stands at around 68% can be improved tremendously by prudent demand side management techniques which include electrification of transport sector as well. 
• The discovery of natural gas in the Manar basin is something that need to be taken into cognizance as we have more than 600 MW combined cycle plants that can easily be powered by natural gas and their capacity too can be utilized to meet the new demand in the transport sector or natural gas can be used directly as a fuel in transport hence detail studies are required to ascertain the best use of the natural gas in the transport sector, from a techno-economic point of view.

In depth and well coordinated studies are needed if we are not to make any more mistakes and nullify what  one arm of the government does with the other. I would like to place on record that, at a seminar conducted by the UGC few weeks ago on the findings of Natural Gas, policy on petroleum and electricity sector was discussed. Politics aside, I categorically mentioned that the biggest mistake we have done in the energy sector in Sri Lanka was the separation of the ministries of Petroleum, Power and the renewable energy as I believe it so. Fortunately now all the relevant sectors in Energy are brought together. So if we are to take any initiative on electrification of the transport sector there should be constant dialog between these two sectors and unified policy initiatives should be adopted with absolute commitment from all concerned. 

I am not going to dwell on statistics or forward any definite blueprints how this should be done as there is enough expertise in this room to do that. Further I am not in any way an expert in transport. However, as a person who was involved in promoting Integrated Energy Planning in the 1980’s with Prof. Mohan Munasinghe in his team, all I can say is there is an ideal opportunity for us to start this effort once again at least with the transport sector for efficiency gains in both sectors.

In the years gone by we had steam locomotives powered by coal, spewing thick black smoke depositing coal soot and dust all along the rails lines that ran in the most beautiful part of the country. Those days we were not bothered about environmental pollution. Now we have Coal power plants with all the environmental safeguards. We have no black fumes, SOx and NOx pollutions are under control. We have a clean and an efficient source of energy, electricity available 24x7 throughout the country with load factors that can be improved that will yield enormous economic benefits. So what are we waiting for? There is an obvious choice an ideal win-win situation waiting to be exploited for greater good of the country.  This will be a case of shifting the fuel for transportation back again to coal shifting away from oil, but this time in a much more efficient and an environmentally friendly and a sound manner.

Moreover we all know there are two predominant transport rush hours in the morning and in the afternoon more towards the evening hours, We have to take advantage of this phenomenon that suits well with the electricity daily demand curve which takes a dip in those times. This should be used with prudence to derive the economic benefit to both sectors and the country at large by electrifying railways and even introducing electric trolley buses.

However, individual charging of smaller motor vehicles need to be regulated with proper power quality standards and tariff making to take advantage of the low price of electricity that the CEB should be able offer to fill the valleys in the daily power demand curves. This can be easily done with proper planning and studies.

In the CEB we have looked at vehicle charging centers before the electric vehicles are brought to the country in large scale. There is an urgent need to get on with the pilot projects that we in CEB were contemplating. This will help CEB to come up with proper standards for charging centers and also a proper tariff to encourage charging of these vehicles in the off peak hours.

We are also well aware of the sliding costs of solar pV panels of which the prices have come down significantly due to large scale pV manufacturing plants that have come up in China. We must take advantage of this now and even solar powered charging centres can be made popular, but all these need careful evaluation before we embark on any one of them. With the large potential of wind to be developed in the country in the future we would be in a position to power the transport of our country to a great extent on Coal and renewable energy sources from today’s 100% Oil base.

We do not lack the expertise on the maters I have raised today. We also have with us Ministers who are committed to do what is right and prudent. We don’t need expertise unlike in building complex power plants or other infrastructure like harbours and air ports. Some decisions can be made with rudimentary studies while others like railway electrification may take few more months of detail studies to carry out the feasibility and detail designs etc. But we all agree this is an urgent need. The country has wasted so much of time we have made mistakes in the past very expensive mistakes starting from scrapping electrified transportation we once had, delaying the Coal power project for no apparent reason, delaying the railway electrification for reasons best known for very few. These are some such very expensive mistakes. The need of the hour is for us all to get together and do what is right.

As I always say to quote from the Bible: “knowing what is right to do and not doing is a sin” Let us not collectively sin by prolonging this discussion any more let us map out a strategy together.

EESoc TAKES A STEP TOWARDS FUTURE WITH ELECTRIFIED TRANSPORTATION

BE READY TO WITNESS THE VIEWPOINT OF EXPERTS AT WATERS EDGE

The fuel of choice for efficient future transportation is yet to be unraveled. Fossil fuels are nearly dying off and it is time to find alternatives. As the leading energy institutions of the world are competing with each other with research and new inventions, electricity for transportation has been emerging as a practical solution. With a variety of locomotives and automobiles powered by electricity, running all around the world, one cannot simply ignore the significance of electrified transportation.

Sri Lanka too became familiar with the concept not very long ago.The introduction of hybrid vehicles from Toyota and Honda to the Sri Lankan market was a milestone in its electrified transportation. Though not very common, the sight of a full electrical vehicle roaming in streets of the suburbs is not rare. Recently plug-in hybrid vehicles have also been present in the Sri Lankan automobile market. All these reasons have made the people more willing to buy hybrid vehicles today.

The Ministry of Transport of Sri Lanka and Japan International Cooperation Agency (JICA) have been working together to formulate a Master Plan for Urban Transportation in Colombo metropolitan area and recently proposed a ‘mono-rail system’ as the solution. Therefore, with all that going on, it is time to raise awareness among the public on what the future holds for electrified transportation in Sri Lanka.

Electrical engineering undergraduates of University of Moratuwa have taken the lead in bringing together a group of renowned personalities of the country to discuss the above matter. In this regard, a panel discussion will be held on the topic “Electrified Transportation – The step towards future” at Water’s Edge, Battaramulla on 12^th of February, 2015. The Electrical Engineering society (EESoc) of University of Moratuwa organizes a panel discussion on a timely topic in their sector as an annual event; where both delegates from public and the public sector, electrical engineers, academic staff of the university and undergraduates meet to discuss and share their opinions.

The moderator of the panel this time will be a renowned senior professor from the Department of Electrical Engineering, University of Moratuwa, Prof. Ranjit Perera. The panel includes six panelists namely; Dr. Narendra De. Silva, Dr. Tilak Siyambalapitiya, Prof. Amal S. Kumarage, Dr. Lalithasiri Gunaruwan, Eng. Lakshitha Weerasinghe and Dr. Beshan Kulapala.

Dr.  Narendra de Silva, the Head of Engineering at LECO (Pvt) Ltd is also a graduate from the University of Moratuwa, and obtained his PhD from Herriot Watt University, Edinburgh, UK. Dr. Tilak Siyambalapitiya, being a fromer president of the Energy Managers Association of Sri Lanka and currently the Managing Director of Resource Management Associates (Pvt) Limited is considered as a premier energy consultant in Sri Lanka.

Prof. Amal Kumarage is a senior lecturer in the department of Transport and Logistics Management of the University of Moratuwa and a former chairman of the national transport commission. Dr. Lalithasiri Gunaruwan is, a senior lecturer of the Department of Economics, University of Colombo and also a member of the Board of management of the Institute of Policy Studies of Sri Lanka, served as the Secretary to the Ministry of Transport of Sri Lanka and the General Manager of the Sri Lanka Railways in his early years.

Mr. Lakshitha Weerasinghe is a charted engineer currently working as a chief engineer in Business and Operational Strategy at the Ceylon Electricity Board. Dr. Beshan Kulapala, a research scientist at CodeGen International, Sri Lanka, presently the project manager of Vega™ Electric Car Project, is an expert in leading CodeGen’s efforts to expand into electronic and mechatronic product development.

While inviting the aforementioned specialists to join the panel to guide the discussion, the EESoc has opened the arena for experts, authorities and other interested parties related to the industry, to share their ideas. Moreover, EESoc wishes to publish the outcomes of the panel for future expansion of the electrified transportation sector. A programme to engage the general public through surveys to enrich the panel discussion with the real world scenarios is already on the way. While raising the public awareness on the subject, this is expected to be a ray of hope to the betterment of the transport sector and the electricity demand management of the country.
