Impediments To A Better CEB

By Kumar David

Prof. Kumar David

It is a shame that CEB Chairman Vijitha Herath is happy to sell his professionals down river for cheap popularity with his political bosses as in his interview in Ceylon Today (23 August, pA4). The sub-heading is “Corrupt Power Deals by last regime – CEB Chairman” and the opening summary statement by the interviewer reads “The power and energy sector in Sri Lanka, mainly the Ceylon Electricity Board is alleged to be one of the most corrupt and most negligent entities in the country. In the past even the state sector worked with the power sector in the most lackadaisical manner – cancelling competitive tenders and at the same time awarding them to those who curry favour with higher ups or private suppliers based on deals. There are accusations that CEB Engineers run a monopoly”. To my knowledge Mr Herath has issued no repudiation disassociating himself from this implied summary of his views, nor has he rejected the association of his name and office from these grossly untruthful slanders.  Is this the man who is going to give leadership to the CEB? Does he not know that corruption in the power sector derives 90% from Presidents, the Cabinet, Power Ministers and Ministry Secretaries from the 1990s up to the present time? Big time corruption in the power sector commenced in Chandrika’s time with the awarding of contracts to build and operate private power plants. Big money went to big players. Do they not teach corporate managers like Mr Herath about reciprocal confidence building? Managers who undermine and untruthfully and publicly ridicule their staff will lose the trust of colleagues and the confidence of the institution.

In the mean time we have had this 8-hour all-Island blackout and an inability to restore full supplies for four or five days. One matter I want to especially complain about is the failure of the CEB or CEB Ministry (erroneously named Power Ministry) to issue a full, frank and transparent public statement. I appreciate a detailed technical analysis will take time and highly placed fools who allege sabotage are doing damage. However, a simple summary would have sufficed to keep speculation at bay. The grape-wine says that a bus-bar was inadvertently energised by maintenance crew before the heavy earthing chain was removed and this led to massive tripping of other circuits and the isolation of Norochcholi. Then it took ages to restart Norochcholi, a known problem which has not been sorted out for 12 years.

Then there was something new that has not been encountered before. When units were brought on line and attempts made, in many different ways, to reenergise Colombo the system repeatedly tripped. Is all this true? Ask the CEB. Three-phase to ground flashovers are uncommon but not unknown and the system should be robust to such events. Why has something not been done for a decade about Norochcholi restarting? Ask Herath. Tripping-on-reenergisation is a new phenomenon that CEB professionals can sort it out given time. However, there has to be stringent outside review of their analyses and proposed solutions. Ministers who smell a saboteur rat under every bed and Chairmen who undercut their own staff will be of no help.

Renewable Energy

Renewable energy sourced technologies for the generation of electricity is one of the very best things that has happened to humanity. The problem is that the God Indira who commands the sun and wind was not equally generous to all corners of the earth.

A one square kilometre site atop the Atacama Desert in Chile or Hardup in the Namib Dessert will produce about 350 GWh (gigawatt hours) and 230 GWh respectively per year. The output for a one square kilometre site in Puttalam, the NCP, NP or Hambabtota will be about 150 GWh per year. [A GWh is 1000 units or kWh].  A 1000MW coal power station will generate about 6300 GWh per year (Norochcholi is 900MW and extension to 1200 is planned). To match this, we will need 42 square kilometres of land, that is close to 10,000 acres! This is the problem! Only countries with huge dessert landmasses can think really big about solar powered electricity. Uninhabited and uncultivated portions NCP, NWP, NP and Hambantota District are good locations for big solar farms but all together it will not be easy to put together more than about half a Norochcholi. As with big-hydro, with wind and solar too once the best sites are used up its saturation; what after that? With other technologies (thermal, nuclear and future fusion power) new plant can be added without such limits.

An attraction of solar power is that prices are coming down steeply. After you factor in lifetime repayment of capital, the future cost of electricity generated from large solar farms will be about Rs 10 per kWh while coal or LNG cost between Rs 7 and Rs 9 depending on global coal and gas prices. Let us agree, prices are comparable. The CEB buys privately generated (IPP or Independent Power Producer) power, when it faces shortage, at about Rs 25 per kWh, again variable with world oil prices. [I won’t waste your time with fractions and decimals which will be out of date between one month and the next. When someone with a little subject knowledge writes media columns the duty is to convey useful and reliable information, not to impress readers with minutiae].

We are in our present predicament because of the stupidity and inanity, respectively, of President Sirisena and PM Ranil who ignored an Expert Committee Report in 2016 which warned that cancelling Sampur coal-fired power station would be ruinous. They had numerous warnings from other experts and CEB planners as well. As a member of the Committee I estimated, and included in the Report, that this blunder would cost the country Rs 220 billion. That now seems a bit of an underestimate and the crisis has arrived sooner than I forecast. I am not playing the usual “this regime”, “that regime” game that the media, corporate chairmen and politician are slick at. The two former Rajapaksa Administrations and the 2015-2019 government have all been grossly stupid in respect of the long and short-term future of the country’s electricity sector. That’s that and QED!

I will not repeat the same story about wind generated electricity though I have jotted down some back of the envelope calculations for my own use. The scenario is similar to solar: It is, like solar, much less polluting and it is price comparable with coal or LNG and much less pricy (only capital costs, negligible running cost) than oil-fired private power. But availability of good sites is limited as with solar (once the best sites are used up as with major hydro, the story is finished – what to do after that?). A very important point is that renewables are big in the public popularity stakes and this is the great selling point for politicians who don’t know the difference between a kilowatt-hour and an LED lamp.

As per the most up to date information on the CEB website (2017) large-hydro supplied 24.6% of total energy while wind, mini-hydro and solar supplied 8.1% – of which mini-hydro was 5.2% all the others 3.9%. CEB thermal (coal and oil) was 52.2% and IPPs (all oil) 15.2% of energy. (It fluctuates a little annually depending on rainfall and unforeseen events like the August 2020 system outage). However, one needs to be ignorant of the basic laws of physics and not schooled in primary arithmetic to say that renewable source electricity will supply 80% of energy by 2030. If in 10 to 15 years demand doubles and no large-hydro is added (only few medium-size projects are left to do) then its relative share will decline, as per elementary arithmetic, to 12.3%. To increase non large-hydro renewables (only 3.9% now) by a factor of five to 19.5%, energy supply must increase ten-fold within 10 years! Only knaves and politicians make such promises.

Has government (President/PM/Cabinet/Subject Ministry) corruption and incompetence been an obstacle to the faster implementation of renewable energy sourced electricity? When competent, rational and honest decision making about the country’s long-term generation expansion programme is undermined by government (all governments) it throws a spanner in the works. Government after government have been ‘playing pandu’; to-LNG or not-to-LNG; to have another coal fired unit or not; to embrace India or Japan or both. When mega private sector companies screw ministers and when nothing is decided properly, it throws the transmission plans out of kilter and demoralises planners. It stands funding including for renewable sources on its head. Therefore, in addition to the technical limitations that I discussed in the first part of this essay, cock-up and corruption at the highest levels – not in the CEB Mr Herath but in governments – is an impediment to a good programme for increasing renewable source power generation.

      Looking at the manner, our people in my motherland gave them an excessive mandate than what they ever expected, I thought to take aback and study it closely. I am sure I am not the only one to have done so, some of our CT readers are taken aback today, not being able to realize the MIND set of the average people in the island. Upside down reactions of the very people is connected with multiple factors.

      There what became evident to me was uncontrollable CYBER CRIMINALITY and srilanken media. Any simple simon with longer membership with lacks of subscribers to his or her YOU TUBE channel, could move above any commenter by reporting FB or YT adminstrations and block their accounts sometimes for no reasons. Iraja Weeraratne, is most known to be the genital organ of Gotabaya election campaign on cyber propaganda. Now he has been doing all the illegal abusing CYBER community … however, our youth are very stupid than that of european counter parts, that would do any low work not thinking twice.
      .
      As some analysts from SL and the world make it clear, CYBER criminality is out of control today specailly to developing nations than the developed ones. For example, if any news being set on air through social media could go viral regardless of its truthfulness or being far near to the truths.

        In terms of YOSHITA RAJAKASHE and his building of prestige hotels across the country is caught by media these days, no matter deforestration and going beyond the national laws regarding conservations of SINHARAJA or any other places that are caught by the attention of not only eco activists but also all born to the srilanken soil, however, nothing seems to be anti-YOSHITHA. This is very typical to srilankan way of news spread within the nation, since FAMILY s underground net works as partners work diehard to paint the picture in favour of them than the other way around.
        This was the very same in terms of that PALACE was started to build by BASIL Rajaakshe and ended up being with stalemate investigations, because plethora of evidence is already availabe to prove the owner as Rajapakshes. And those other stories ” dazy granny’s sack of gems etc were very known to the very same audience over the years. Nothing seem to overtake Rajakshe CYBER criminal power.

    I am not an expert on the subject of electrical power generation but today, the emphasis is on renewable sources & coal fired power plants are considered to be the most hazardous to our health in the form of pollution. The nuclear energy is not an option for SL, considering the lack of current technical expertise in managing such a high risk operation.

    Having exhausted hydro power, we have obviously no option but accept environment polluting coal thermal plants but wouldn’t the strain on the national grid be reduced if the govt. encourages wind farms & household solar panels? In land & off shore wind farms are a common sight in developed countries, particularly, in Europe. So are wind farms not feasible on the balance of a population with reciperotory health

    In a a sun-drenched land with flowing rivers all round like Sri Lanka, any source of power using either fossil oils or coal with massive carbon emission footprints should be actively discouraged. Clean renewable energy has been the norm in most developed nations for decades. Why not in paradise? No inflated contracts or bribes available?

        We should welcome EDWIN warmly and wish him a LONG LIFE !.

        I know EDWIN very well. So do Native Vedda and all of the other CT commenters. He is from Mathugama Area and should be a sexagenarian (Prof. KD should then be a nonangenarian ?).Edwin usually does not take time to read CT articles but enjoys adding his posts to the comments.

        This was unique to him. He always praised his GURU Prof. KD on and on, and went disspeared being caught by polygamy stuff. Polygammists are known to Africa yet today but also to Srilanka until recent days.

        I praise only my CT GURU – SINHALA MAN . As for me he is so gentle/polite/ and srilanka would not have been caught by criminals as is the case for now, if there were more SMs in that island. His energies standing against the corruption of all forms are highly commendable. His gentle nature goes beyond putting together of all gentle charactors I am known from srilanka. I go mad when I dont get time to read his posts. All these few days, I thought he may have been aducted by white van criminals. He was naively open to the readers also displaying his ID particulars.

          Btw, I thought Edwin may have kicked the bucket in between or Rajakashes may have slaughtered him to the manner they did it with that YOUNG RUGERITE -Wassim Thadjudeen.
          Election outcome proved the world, that srilanken voters are the most tolerant people for even high crimes and crimes doers. That man who was convicted as the high criminal was elected by people. Jonsten Fernando and his criminal gangs demolished archaeologically valuble building in Kurunagala, but people elected him. Rajaakshe famly killed Wasim and a bunch of youth of colombo tamil families, but they are all elected. THE LIST GOES ON.

      It is hard to teach truth to Lankaweyans (No exemption to Prof. Kumar, who the Original son of Mother Lankawe but he likes to spend his retirement in sunny lands). In 2015 Ranil’s speeches, on stage after stage, was Colombo Pong Cing was a project environmental study not properly carried out. Modayas and Sinhala Intellectuals voted for and selected him. Then, when Malik Samarawickrama went to China and came back, Ranil came out with the idea of selling Hangbangtota Harbor to China and rubbished the new Environmental study for Colombo Pong Cing. (Anyway China added $280M to cost and plucked additional land). But now the pearly Western Ceylon beaches are being sea eroded. We told many times that Sampur project was not real one, though Prof. Kumar had inserted his tail too in that. Let’s try to see the long story short. Sampur was captured by Rapist Navy and many inhuman murders were carried out including some Action Farm employees. These cases still not shorted out, though IIEGP got involved that. Sampanthar asked from Old King to release it. Sampanthar kept claiming that India was going to help him too. India started to feels jealous of the treatment China was receiving from the victorious Lankawe after war, though it was India who helped Lankawe to win the war without charging a penny.

      So India too wanted to build a Coal plant and connect its grid with Lankawe. India thought that will allow it to keep an eye on Chinese electrical activates in Lankawe. Another point here, I opposed only using captured Sampur Land to Coal plant, not the Power grid business. Ok, I agrees this uneducated boor, know nothing of the power need, opposed Sampur coal plant; but can Prof Kumar say what happened to grid connection India proposed? Couldn’t it have helped to balance the last problem, temporarily until it is fixed? Is that also me destroyed the Grid connection project?
      May be, that time, PM Manmohan Singh thought Nuraicholai would be only deal Lankawe would have with and China. Any Lankawe Lankawe did not corporate with him on any Power related Projects. Sonia was fully with Old King, but PM Mohan Singh grumbled that “If we tell Lankawe it is not listening, what we can do for that”. Singh is naive, we do know that. So to keep India and Sampanthar get tangled, Lankawe offered Sampur’s captured land for new Coal Project. His idea was, after all, if he could not resist India he can colonize Sampur, a Tamil land, with power plant. In any case Old King was not that mouse for Manmohan Sigh to walk over that easily.

      Professor Kumar is suffering from Amnesia, which I don’t blame him, because I too like him or may be worse than him these days. He is doing his usual number jugglery & banging bottom too much on the drum but not talking anything about the Sampur plant’s environmental study. When Manmohan Singh left, PM Modi, the new broom was sweeping well for few months until Old King devise his technology to deal with Mr. Modi. PM Modi restarted the Coal Plant talk. Sampanthar grumbled again. When new King came, two options merged out, 1. Relocate the plant or 2. Refuel the plant with LNG. The leading one was alternate fueling the plant with LNG. It received opposition from south that it will be costly. In the meantime the entire north rejected 65,000 Iron cages, which even Morotuwa professors opposed as environmentally disaster. Seeking North resistance to destroy their lands, New King went for better options like going with Kanthalai Sugar factory, which was higher ROI (Commission) for him than peeling the fiber from Sampur, which openly opposed by China. Professor Kumar might know his number jugglery in electrical engineering, but he has no idea what kind politics is going in Lankawe. There is no truth all that it was an employee caused the last power cut. We show this from 1948 up to in 4/21 and Sainthamaruthu house bombing.

Off shore & in-land wind farms are a common sight in developed countries, particularly, in Europe. So are wind farms not feasible & solar panels in homes & industries a drop in the ocean, not to be taken seriously?

    Prof, I admit to have A/L knowledge on electricity and power. I believe the inquiry report came back as “human error”. So we are good to go. I recently read more than 1/3 (or is it more ) of our total electricity is currently supplied by Norochcholi , which claims the infamous record for breakdowns. I believe recently some Russians guys were called in to give a try. As long solar is concerned I do not know how practical it may be, but as a fact Cochin Airport is FULLY supported by its own Solar Farm, and in certain months they even sell the surplus to government. At least on individual basis such power supported projects will ease some burden on Grid. Projects like “Port City” should have been mandated to come up with their own power supply.(after all China is selling solar panels to rest of the world).

      Chiv,
      Sunshine stories like Cochin airport are nice, but what happens when it rains for a week? It does in Cochin. Then the airport buys power . The capacity to supply auxiliary power has to be paid for and maintained whether it is needed or not.
      As to Chinese solar panels, you should talk to house-owners who have used them for 5 years. They have found to their chagrin that the purported 25 year warranty does not guarantee that the panels will produce the same amount of electricity over 25 years!

        Solar cells like CFL lamps and many other electronic devices will deteriorate.
        A warranty can cover life but not peak performance. I expect that it will be the case even with German devices, which rank among the best, technologically.
        Buyers have to work out the economics themselves.
        *
        When I sought advice from a senior electrical engineer about electric pedestal fans, he said “Buy the cheapest among known brands because, at much less than half the price of the top brand, you are better off even if the product lasts 2 or 3 years, as no fan is going to last well more than 5 or 6 years near the coast.
        I followed his advice, and the cheap fan is still running well after 4 years, although the frame has gone rather rusty but not yet flaking.

          “Buy the cheapest among known brands”.
          Exactly my philosophy. It will last, as long as you know it’s weak points, like needing a drop of oil now and then unlike the ones with expensive bearings.
          I believe the plastic covering on some Chinese panels turns progressively opaque, like the plastic headlight lenses on cars. There are Chinese panels with better coverings, but they aren’t cheap.

          why dont they yet introduce SOLAR villages to SRILANKA? Why do they stay debating ? What have they been doing not having achieved an inch of progress in any areas as many other country have been doing ?

            I think that this has been answered by Kumar David among others on these pages.
            Neither wind nor solar energy can be a substitute for conventional energy.
            They have a few windmills operating along the west coast. Their cost effectiveness may not be that brilliant for expansion on a significant scale.
            Our wind energy potential may not be good enough.
            we need numbers. There is a lot of hand waving talks but one has to work out the fine details.
            Our major handicap is that both will be imported technologies and we will pay extra for that.
            My answer to the problem is consume wisely and avoid waste.
            Is our increase in electric power generation matched by an increase in industrial output?
            Until then, I am not keen on more electric generation but for total rural electrification.

    It is so exhilarating that I completely forgive you for the 3.5 out of 10 marks you gave me for my course work report on the Mercury Arc Rectifier back in 1965. Mercury Arc Converters are Museum pieces now, having being replaced by Solid State Devices such as Thyristors, MOSFETs and GTO’s.

      As an educational device, the mercury arc rectifier is valuable. The trouble now is that it is too expensive and needs careful maintenance.
      Many of the devices that went with the reciprocating steam engine are engineering marvels and unmatched educational devices to explain various operating systems.
      The problem with solid state devices is that they are all black boxes, and the student often accepts without question what the LCD display says like blindly believing software design packages.

          Old,

          Mathematical intrigues have a nature to fascinate and entertain brain (not just human brain – every time when I sit down somewhere with spanner or screwdriver, my cat will come demand to let him do that). The fancy mechanisms entertaining (human) brain is just another side of fairy tales to children. In O/L I just to sit down and keep playing with catalyst in geometry to prove something that cannot true. On this, the visible angle (Vision) creates attraction for everybody. Gramophone uses flywheel and governor to balance load and timing of the spring. But as you said governor more interesting to watch, rather than just spinning flywheel. One time it was interesting to watch Petromax stating from spirit and switching over to kerosene & mantle glare. To watch that, I shut them off, tough for immediate restart, one cannot use sprite. Another simple device but do very complex control is “compound pendulum” & Grandpa Clock. Until the solid state electronic controls were invented, Mechanical devices, especially large ones like train and steam engines used many of these. Earlier devices needed abundant manufacturing skills because they exploited many different natures’ physical laws. These magnificent Instruments, they elegantly moved while hey functioning & mesmerized human senses. Contemporary solid state devices may be a temporary entertainment for programmer. But once they are out of his/her hand, nothing in that to wonder.

    Also, let me say one thing. CEB has 1000 Engineers, and if that produces a power system that fails repeatedly it is a failure. will all due regard to all my friends and colleagues from Efac.

    I have lived in many countries that are considered fully developed. and the difference or one of the major differences is that over 30 years in these countries there have been no power failures by and large. whereas in underdeveloped countries power failures are common.

    So if you engineer are worth your salt. you would make sure this is heeded.

      How can they have proper systems when do not recruit best from EFac if one is a Tamil.
      I know an Engineer quite fears ago who got first class in third year and 2nd in final while everyone expected a first. He applied to CEB but he was rejected all the jokers without class were recruited.
      Simple reason he was aTamil.
      A sinhala Buddhist country ignoring meritocracy can not have fail safe power supply system.

            Dear rj1952,
            .
            It may be that I should send you another email.
            .
            To find out about this thing called “Yakko lingo”.
            .
            I’m a simple human being who is a citizen of Sri Lanka. Both are brute facts. I’m neither proud nor ashamed of these things that are objective facts.
            .
            I’m myself, a guy who reacts against what is usually referred to as Sinhala-Buddhism. On the other hand, I have found Stanley to be a guy who has a head on his shoulders. We have possibly not quite understood him.
            .
            I don’t understand anything of the Tamil Language, but I know it to be one of the oldest languages in the world, and I have immense respect for it; we were actually taught a little about its Literature in the University – just the five in my batch who were reading English.
            .
            I also know Sinhalese very well – it is said by some to be my “mother tongue” although that is an outdated concept – although I feel that I’m capable of using English a bit better. Let me admit, however, that my home has always been this beautiful island, Lanka and my English is by no means perfect, since I’m not what is tyrannously called “a native speaker”.

              A paragraph seems to have got lopped off, possibly owing to the length of the comment.
              .
              I had said that this “Yakko lingo” I understand to be a disreputable hybrid used by the uncultured urban under-class of Colombo. It’s sad, but had I grown up in such an environment, I’d also have run away from there.
              .
              rj1952 claims to have run away from our country, yet comments on it, still using the same lingo.
              .
              Is it that having got to Australia, there too he has found the place most congenial to be some inner city area inhabited by drug addicts, pimps, prostitutes and worse? If such were not his associates, how could he possibly write the way he does?

                I dont think RJ is a racist. He is anti-Mahinda Rajapakshe and his racial politics. So do I… but I am a sinhalese and he is a tamil. We are both srilankens born in that island.

                Who is a Racist?
                A racist is a person who shows or feels discrimination or prejudice against people of other races. He or she often believes that a particular race, typically his or her own, is superior to other races. A common example of racism is determining the inferiority or superiority of a race by the colour of the skin. Racist ideas often stem from ignorance, non-familiarity with other races, and the superiority complex about one’s own culture.

                I think those who support RAJAPKASHISM – are racists. I have no idea as to why people supported them. We have had enough evidence to prove that Rajapakshes were against srilanken MINORITIES.

        This is completely untrue. There are many Tamil engineers in the CEB. if your buddy was not recruited there would have been a Very good reason. I remember once a Sinhalese guy with a first-class was not recruited as he was a known JVP agitator and was not recommended by Prof Jayaseksra.

        The CEB is very close to the Engineering Faculties. and the professors of Electrical Engineering are listened to by the hierarchy. And I don’t think there would be anyone who knows these professors and department heads who would call them Racist. ( a little eclectic but certainly not racist.)

          How do you know? There seem to be too many assumptions.
          The reason for not being selected need not be the one that the candidate assumes.
          Generally people name their own referees and the employer does not seek the views of former teachers.

            This is not an assumption. This is something I know from direct knowledge. I know all people involved.

            And you are correct a first class is not a guarantee of capability.

            That is not the point . 1000 well-qualified Engineers should be able to easily maintain a small system like Sri Lanka. Most private companies in other countries do not have it. If you remember right during my College times both SLT and CEB were Govt run. Now SLT has been privatized and in fact, provides much better service than they ever did as a Govt entity. Lets hope that will not be the fate of the CEB.

              Direct knowledge of Prof. J. not recommending?
              Was he asked? I doubt unless he was on the selection panel.
              Sorry to say that since privatization the bus service is rotten.
              SLT’s improvement has more to do with the advance in technology.

        I did not say in developed countries there are absolutely no power failures or blackouts. I remember the east coast blackout brownout that took 1-2 weeks to resolve. and as for the power shutoffs in California to prevent fires, they do happen. but nothing compared to the frequency of it happens in Sri Lanka. The Quality of power is so much better and the outages are so much less.

        In spite of all these rolling blackouts etc you mention I have been in the Silicon Valley for 4 years I have not seen a real power outage.

      I wonder where you were at the time of the following:
      UK 10 August 2019
      Nearly a million people have been affected by a major power cut across large areas of England and Wales, affecting homes and transport networks.
      New Zealand
      The 1998 Auckland power crisis (19 February to 27 March 1998) was a five-week-long power outage affecting Auckland. Another serious one occurred on 12 June 2006
      USA
      Southwest Blackout of (2011) is said to be the largest in California’s history, caused by state’s dependence on power imports from Arizona.
      There were several other outages elsewhere in the US caused by cyclones and other events.

        1. England and Wales, New Zealand, USA are not Sinhala/Buddhist countries therefore it does not matter if power cuts affected those people unlike Sri Lanka.
        2. It is not a huge shame if Power outages happened in these countries.
        3. These countries are not run by Single handed generals
        4. These countries are not ruled by self proclaimed strongman.

        “Also, a First Class is no guarantee of good aptitude. Some of the best engineers I know got ordinary passes, like the late Eng. Jayamanne of the Cement Corp.”

        If so no degree is even better, Wimal Weerawansa is the current Minister of Industries, who promised to restart Odduchuttan Tile factory, Valaichenai Paper Mill, …. some 60 years old industries,…

        Being Wimal Sangili Karuppan Weerawansa is an added advantage.

        I don’t see your point. The issue is not a few power outages caused by storms hurricanes etc.

        Look at the quality of power in Sri Lanka. in the night the voltage gets dragged down due to lack of power. There are frequent trips to the system. I understand the Distribution of the power is not up to the CEB generation and transmission is. But still the quality of the product is low. Not all this is the fault of the engineers. Clearly there is not enough generation. and the politicians are to blame too. These so-called environmentalists are also a problem. There is no way wind or solar can generate what is needed at the price we want.

    On Wed 8/12 Maintenance work is planned for a specific piece of equipment (or section of the grid) on Friday 8/14. 2 days ahead of actual work day)

    2) On Wed 8/13 alert issued due to a shortage of authorized personnel and/or equipment

    3) At 9:00 AM on 8/14 flexible alert issued most probably about a delay in work completion

    4) At 12:00 AM on 8/14 warning issued most probably about a further delay in work completion beyond system peak load time.

    5) After work completion, while trying to deisolate and energize the isolated section, a maloperation occurred. Most probably it was a forgotten earthing device.

    The excessive hurry in which the work was done, due to the resource shortage, may have been a contributory factor.

    Anyway the subsequent operation of the protection system caused an initial loss of generation of 475 MW (a large loss).

    6) It appears that the UFLS was allowed to operate rather than manual load shedding.

    7) As the system load increased and the generation decreased due to Solar PV decreasing the final UFLS stage operated causing the blackout.

    I smell a rat here. Shedding of a large but less priority section of the system manually could have saved the situation by leaving certain parts intact. This would have quickened the restoration.

      Continuation:

      2nd Part of Above comment

      The time of shedding firm load is 6:36 PM close to sunset time (6:25 PM). The Solar PV would have gone off for the day at the time leaving other sources to fight the battle.

      Recommendations:

      1) Let PV go for lunch around 10 AM, have a siesta and return to battle around 2 PM. After that don’t allow them to run away from battle stations.

      2) Install sufficient BESS to go on till at least 2 hours (6:15 to 8:16 PM).

      3) Get a 1000 pedal bikes and force the RE enthusiasts to pedal them from dusk to dawn when such thing happen.

    Hello Edwin,
    It is likely that you were a few years ahead of me at Peradeniya University (noting that you did the Mercury Arc Rectifier coursework in 1965).
    /
    Another explanation!
    When a large block of generation is lost, the UFLS relays are activated to shed load at specific frequency levels. If the inertia of the total rotating mass that remains connected is low, then the rate of change of frequency (ROCOF) could be very high. So, the system frequency drops at a very high rate [df/dt in excess of 5] such that the frequency collapses before UFLS relays could have any impact. This is because there is a finite time delay between UFLS relay pick up and the actual disconnection of loads.
    This is precisely what happened with a reasonably large power system when it separated while importing closely 1000MW. The separation and the disconnection of large synchronous generators within the separated network were caused by transmission failure (lightning caused multiple transmission line faults). The solution was to deploy UFLS triggered by df/dt with no time delays.
    I am not suggesting that this is what happened in Sri Lanka.
    There could be another explanation for the power system failure.

    Dear Folks

    Do we have in the SL administrations since inception a think called “parliamentary committee” as such please? This is normally a multi party panel of MP’s who are assigned to various Committees from the time of oath by their respective parties based on their capabilities……they may be supported by Clarks etc.

    Various people get invited to this panel and asked questions/scrutinise the event and establish facts, written submissions are also accepted and logged In the respective website. All the outcome of the interview from various experts, Director General, universities, example energy ministry…from the ministers to the clerical servants all can be called to the committee session. This is broadcasted life to the Nation.

    This way we avoid speculations and the Nation get to listen to the facts from the respective people??the action list then get transferred to the respective bodies. There are multitude of benefits based on this activity?

    The cost of wind power is US Cents 3.7/KWh and Tamil Nadu is the leader in the generation of wind power. Sri Lanka with its location in Palk Straight has the potential to meet a significant percentage of its power requirement from Wind Power. Sri Lanka should call tenders for the supply of wind power on land leased by the government to replace the high polluting new coal power plant with Wind Power and LNG. Further details are given below. https://en.m.wikipedia.org/wiki/Wind_power_in_India

      Have you checked the wind regime in Sri Lanka?
      It may be feasible, but cost may be a little higher than for India.
      We need to think of other factors too including environmental impact.

        I think nothern and southern provinces have plenty of wind, so that wind mills could easily be introduced to them. We see lot more wind mills in nothern Germany than any other areas in Germany.

    Wind mapping shows that the strip from Kalpitiya to the Mannar Island and the Jaffna Peninsula has good to excellent wind speeds for the generation of wind power. The Minister of renewable energy should visit Tamilnadu with a team from CEB and perhaps PUCSL to study how Tamil Nadu and the southern states of India have used the wind blowing through Palk Straight to produce low cost wind power. Further information is given in this link. https://www.nrel.gov/docs/fy03osti/34646.pdf

        Dear Folks

        I am all for renewable energy but with the limited land space we have should we not explore wind farms in the sea as several nations have done this too. There is a concept called using the sea currents and waves too. India has done lot of work on the wave energy too.

        Just to share please check out this documentary as well please where we need to do a lot of duedlligent work before we embark on this path too

    There are over 17 islands in the Jaffna peninsula and they can be used as sites for wind farms, in addition to the coast. Wind turbines can be also erected in the shallow water without much cost. We need to harvest the wind power resources of Sri Lanka, which is enough for us to even export wind power like Denmark, which is laying a cable to export power to UK.

      L De M,
      This is also true:
      “In 2007, household electricity prices in Denmark were the highest in the world and, along with Germany, the country currently has the highest prices in Europe.”

          For Readers knowledge

          Why are electricity prices so different in Europe?
          The energy prices in the EU depend on a range of factors, including the geopolitical location, taxation, network charges or environmental protection costs. The prices for electricity procurement and supply [network costs] have remained stable in Europe over the past 10 years. The average rose from 12.3 cents per kWh in 2010 to currently 13.2 cents.

          Taxes and levies make the biggest difference. Their share climbed steadily, from 25.6% in 2010 to 36.6% in 2019. These values vary greatly from one country to another, with rates as high as 63,7% in Denmark and 52,3% in Germany. The lowest taxes are paid in Malta at 7%. Ireland is also at the other end of the tax scale, paying only a tax premium of 16.3%.

    This link says the budgeted cost of wind power in India is Ind Rs 2.50 per KWH. Even adding 100% for the transmission cost, the price is lower than the total cost of high polluting coal power which is affecting the air quality in many parts of Sri Lanka, including Colombo. https://www.evwind.es/2020/03/31/total-wind-energy-in-india-are-expected-to-reach-between-48-gw-to-54-gw-by-2020/74234
