  1. Like to know how such a plan could be prepared accepted when the National Energy Policy and the Input data for LCLTGEP is finalised.
    In case this program is reviewed it may need to be redone soon to meet above requirements. Gives better opportunity for CEB to learn better planning.

  2. I do accept as true with all of the ideas you have presented in your post. They’re really convincing and will definitely work. Nonetheless, the posts are too quick for beginners. Could you please prolong them a bit from subsequent time? Thank you for the post.

  3. It’s appropriate time to make some plans for the future and it’s time to be happy. I’ve learn this put up and if I may just I want to recommend you some interesting things or advice. Maybe you could write subsequent articles regarding this article. I want to read even more issues approximately it!

  4. As an Engineer, I feel we should invest more on renewable energy like solar, wind OR/AND pumped storage hydro. Our goal is to remove all fossil energy by 2037. This should be the vision of our country where we have ample amount of solar energy. Please study cases on other countries like Germany. Our target should be that. Even south Asian countries like India has the similar vision and goals. Why we still go for oil based power??. People are much more aware about pros and cons than those days. So please think to stay on power by doing good for long. not doing bad and stay for short. We hope our Minister has a good vision on this. Thanks.

( දුම ඉක්මනින්ම රටෙන් ඉවත් වීම). අනික හම්බන්තොට වරායෙන් ගල් අගුරු ප්‍රවාහනය පහසු වීම.

  6. To Whom the cost be least?

    Least Cost should be to the public, not to CEB, though CEB is doing a hard job.

    PUCSL also shall look into direct and indirect benefits to the society. Such as job opportunities, technical enhancement of the society, wealth distribution among people, opportunity for indigenous entrepreneurship etc.

    CEB at her own discretion might or might not look into those aspects.

  7. 1.India has v.recently scrapped a large coal powered power plant in preference to solar power where the prices are seen tumbling.

    2.What is the loading price of say 1000tons of co2 and other gases used by the CEB in their LTGEP wrt thermal power plants?
    3.In their a proper qualitative or quantitative study done in this regard?.If so pl gige references

  8. There are two abandoned energy sources available in Sri Lanka but, no researcher or government institution showing interest to utilize them.

    1.Sea weaves
    Potential energy stored in Sea weaves can be easily converted to kinetic energy using various mechanical arrangements.

    (a) One method could be large floaters connected to leaver system can let it freely float on the sea weaves. And connected leaver system to those floaters can be used to pump sea water to artificially build reservoirs in high ground level. Small hydro power plants can be built below the reservoirs or underground to generate electricity. Instead of using traditional turbines, can be use thrust engines or engines built using Pascal’s law to increase efficiency in power generation.

    (b) Second method could be using the energy generated through this kind of floaters can pump air instead of water and compressed air can be stored in huge steel tanks. Compressed air can be used to run turbines to generate electricity.

    (c) Freely floating spiral like structures connected to gear system also can be used to rotate gear wheels and transform potential and kinetic energy of sea weaves to mechanical force and then converts into electricity using compressed water or using compressed air.

    Since Sri Lanka is surrounded by the sea, it is possible to build large number of small to medium size power generation plants around the country. Using those, Sri Lanka’s power requirements can be 100% fulfilled using sustainable energy.

    2. Bio-Gas
    Small to medium size bio-gas plants can be built by each municipal council and it also helps to solve garbage problem currently faced by the entire country. Instead of polluting rivers and lakes by sending sewerage into rivers, those can be directed to these Bio-gas plants. Bio-gas generated through such plants can be easily using to fuel existing diesel or kerosene powered generators with small modifications.

    Wastes generated in and poultry industry and through farming and agriculture can be used to generate bio-gas and this will become an additional income source for farmers and SME sector. As a bi-product, these bio gas plants can sell organic solid fertilizer and liquid fertilizer to farmers. And this will help to save large foreign exchange annually spend for fertilizer imports. Furthermore, it helps to reduce the soil and water contamination as well as kidney diseases occur through heavy chemical fertilizer usage.

  9. The base case plan continue to pump coal power even after 2025 which is a big item to be revised / rethink as most of the countries have committed to retire coal power after 2025 like Briton, ( 2025) France ( 2023 ). In my opinion these plants should be replaced with Small modular Power Reactors ( SMPR ) s or Advanced Combined Cycle technologies as the industry forecasts the LOCE could drop to $ 90/MWh and $ 83/MWh respectively by 2025 in 2013 dollars . The LOCE for those technologies will definitely become competitive with other forms of electricity generation. ( please refer to US EIA for levelized costs information )
