Development of renewable energy projects

By Dr Janaka Ratnasiri

MINI-HYDRO SYSTEMS

Sri Lanka being blessed with a large number of streams cascading in the hill country, there is high potential to harness this source of energy. In fact, the first mini-hydro plant was built by British planters in tea estates even before the large systems were built. Currently, there are nearly 190 mini-hydro plants with capacity below 10 MW installed in all districts in the hill country with an aggregate capacity of 394 MW as at end of 2018. Their PFs vary between 25% and 55% with only about 10% having PF above 40%. The average price paid for energy from these mini-hydro plants is LKR 14.45 a kWh (CEB S&G Data Book 2018).

The SLSEA Plan has recommended installing additional min-hydro systems with capacity 110 MW by 2025. However, building these plants are not encouraged because of the many adverse impacts they cause to the environment including depriving water to people in downstream, forming puddles which could cause breeding of mosquitoes, affecting fish habitats and general ecology and aesthetics.

DECLINE IN BUILDING

RENEWABLE ENERGY SYSTEMS

It is observed that there has been a decline in the addition of renewable energy (RE) capacity during the past few years. It appears that the CEB has imposed an embargo on their development apparently citing a legal issue. When this matter was brought up at a TV panel discussion some time back, a senior official sitting in the panel representing CEB responded by saying that the applications for building new RE projects were put on hold on Attorney General’s (AG) advice.

The addition of generation capacity into the national grid is governed by the provisions in Sri Lanka Electricity (Amendment) Act, No. 31 Of 2013. Such an Act has been brought in to facilitate the introduction of additional capacity rather than to prevent such addition. If the AG’s ruling for disallowing building of new RE systems is due to any inconsistencies arising out of poor language in the Act or due to difficulty in interpreting its clauses, the Ministry should have taken the initiative to bring in suitable amendments to the Act in consultation with the AG to remove such inconsistencies and remove any conflicting clauses, so that whatever legal issues that prevent addition of new RE capacity could be removed.

INDIA’S OFFER TO BUILD A SOLAR PARK IN SRI LANKA

The Sunday Island of 26.07.2020 carried a news item describing a programme to promote solar energy utilization globally launched by India in collaboration with the Government of France, as a side event at the Climate Change Conference held in Paris in 2015. This programme called the International Solar Alliance (ISA), was established by the Prime Minister of India and the President of France on November 30, 2015, with the objective of scaling up solar energy, reducing the cost of solar power generation through aggregation of demand for solar finance, technologies, innovation, research and development, and capacity building. The ISA aims to pave the way for future solar generation, storage and technologies for member countries’ needs by mobilizing over USD 1000 billion by 2030, according to the India’s Ministry of New and Renewable Energy (MNRE) website (https://mnre.gov.in/isa/).

The above news report further states that India’s state-run National Thermal Power Corporation (NTPC) Ltd plans to set up a solar energy park in Sri Lanka under the aegis of ISA. It is not known whether India has made a formal communication on this to the Government of Sri Lanka and how the local energy authorities will respond to such an offer. Sri Lanka’s own plans to build solar systems will not exceed 1 GW capacity even by 2025, according to SLSEA Plan. This is far below the installations in India which has reached 34 GW in 2020. Being a member of ISA, Sri Lanka should welcome India’s offer to build a solar park in Sri Lanka under ISA. Under the terms of ISA, India only facilitates sourcing of funding and services and the host country has the ownership for the project, who is required to do the preliminary ground work to seek funding. It is hoped that the local energy utilities will accept this offer.

PROBLEMS FACING IN EXPANDING RE SYSTEMS

When more and more RE systems are built, their integration into the national grid may pose some problems. One is the rapid variation of the output of solar and wind systems. With the development of software that could forecast these variations on-line, it is possible to increase the penetration of RE systems into the grid. If necessary, CEB may acquire this technology from any foreign country who has already implemented high penetration of RE into their system.

Another is the need for storage for saving the electricity generated during the daytime by solar systems for use at night time. Often, what is proposed is to introduce high capacity storage batteries for this purpose. However, with the availability of hydropower reservoirs, a better way to save energy generated by solar systems is to avoid using hydro power during the daytime by an amount equivalent to what is generated by solar system. This saved hydro power is then available for using during night time (see article by Chandre Dharmawardana (CD) in Island of 15.07.2020).

A third problem often cited by CEB is the lack of capacity of the transmission system to accommodate energy generated by RE systems as planned. According to CEB, installing more than 20 MW of wind capacity in any given region may adversely impact local grid stability and power quality (NREL Study, 2003). This problem could be solved by improving the substations in outstations and increasing the capacity of transmission lines connected to them.

A fourth problem, particularly applicable for large scale solar PV systems is the difficulty in identifying suitable land in areas of high solar insolation. Unlike in India, Sri Lanka has limited land available for building solar parks which require nearly 1 ha for every 1 MW of installed capacity. One way to overcome this problem is to utilize the large number of reservoirs available in the country to build solar systems (See CD’s article). As mentioned before, government has already decided to build such a plant with capacity of 100 MW at Madura Oya reservoir.

ACHIEVING 100% DEPENDENCE ON RE SOURCES

If the above impediments which prevent incorporating more RE systems are removed, it will be possible to do away with planned fossil fuel power plants altogether, particularly the coal power plants which cause heavy pollution and achieve 100% penetration of RE systems as found feasible in a report released by ADB/UNDP in 2017. The CEB will then have to discard its current Long-Term Generation Expansion Plan which gives priority for coal power plants and prepare a fresh plan giving priority for RE sources.

Though the cost of coal consumed in a coal power plant may appear cheap and hence given priority in the CEB Plan, when the heavy expenditure on operation and maintenance as well as external costs including cost of damage to the environment and health of people are added, coal power is no longer cheap. A report released by the Public Utilities Commission of Sri Lanka (PUCSL) in 2017 revealed that “total cost at Puttalam plant is LKR/kWh 18.60, excluding environmental costs and cost of long Transmission lines”. (https://web.pucsl.gov.lk/english/wp-content/uploads/2017/11/brief-anlysis-cost-of-generation-2017.pdf).

Hence, it is desirable if the present and planned coal power plants are replaced with RE plants. If the entire generation from fossil fuels including coal amounting to about 8,400 GWh currently is replaced with RE projects which will cost only LKR 10 per kWh with no cost of externalities, it could save the CEB about LKR 110 billion annually. Hence, sooner it is done, the better it is for the economy of the country.

BENEFITS OF SHIFTING TO

RE SYSTEMS

In addition to financial benefits accrued by shifting to RE systems by avoiding fossil fuel combustion, the country stands to gain several other benefits. One is the avoiding of environmental pollution caused by emission of gaseous pollutants including oxides of Sulphur, oxides of nitrogen, particulates which are health hazards to people. In addition, damage caused to agricultural crops, fisheries habitats and to health of the people by ash accumulated after coal combustion could be avoided.

The other is the avoiding of emission of carbon dioxide into the atmosphere which contributes to global warming and in turn causes climate change. Being a signatory to the Paris Agreement on Climate Change, Sri Lanka has pledged to reduce carbon dioxide by a specified amount voluntarily. Shifting to RE sources is a convenient way of achieving this target. Sri Lanka is eligible to receive financial benefits for undertaking RE projects in view of the saving of carbon emissions, which the government should pursue by submitting suitable project proposals to the Climate Change Secretariat.

CONCLUSION

The private sector has taken the initiative to build many RE projects up to 2017 generating altogether 1,830 GWh of energy in 2018, which amounts to 11.9% of the total generation of 15,374 GWh (CEB SD 2018). However, there has been a decline in RE development in recent years apparently due to a legal impediment which needs rectification immediately. Power was purchased from unsolicited RE projects built initially at rates valid for 20 years which have been overpriced compared to rates offered for new RE projects based on competitive bids. By expediting shifting to RE projects as planned up to 2025, government stands to save around LKR 43 billion annually.

If the present generation of 8,400 GWh from fossil fuel combustion is replaced with RE sources, it could save CEB around LKR 110 billion annually. To realize this, Government should raise the upper limit of 10 MW for building RE projects by the private sector, enabling it to undertake larger RE projects. Sri Lanka should make an effort to secure financial assistance from Climate Funds to shift from proposed fossil fuel generation altogether in the future moving away for more RE generation integrated into the system.

V. Shanmuganyagam (1940-2026): First Clas Engineer, First Class Teacher

Published

on

Quiet flows another don. The aging fraternity of Peradeniya Engineering alumni has lost another one of its beloved teachers. V. Shanmuganayagam, an exceptionally affable and popular lecturer for nearly two decades at the Peradeniya Engineering Faculty, passed away on 15 January 2026, in Markham, Toronto, Canada. Shan, as he was universally known, graduated with First Class Honours in Civil Engineering, in 1962, when the Faculty was located in Colombo. He taught at Peradeniya from 1967 to 1984, and later at the Nanyang Technological University in Singapore, before retiring to live in Canada.

V. Shanmuganayagam

In October last year, one of our colleagues, Engineer P. Balasundram, organized a lunch in Toronto to felicitate Shan. It was very well attended and Shan was in good spirits. At 85 he was looking as young as any of us, except for using a wheelchair to facilitate his movement. The gathering was remarkable for the outpouring of warmth and gratitude by nearly 40 or 50 Engineers, who had graduated in the early 1970s and now in their own seventies. One by one every one who was there spoke and thanked Shan for making a difference in their lives as a teacher and a mentor, not only in their professional lives but by extension in their personal lives as well.

As we were leaving the luncheon gathering there were suggestions to have more such events and to have Shan with us for more reminiscing. That was not to be. Within three months, a sudden turn for the worse in his condition proved to be irreversible. He passed away peacefully, far away across the world from the little corner of little Sri Lanka where he was born and raised, and raised in a manner to make a mark in his life and to make a difference in the lives of others who were his family, friends and several hundreds of engineering professionals whom he taught.

V. Shanmuganayagam was born on May 30, 1940, in Point Pedro, to Culanthavel and Sellam Venayagampillai. His family touchingly noted in the obituary that he was raised in humble beginnings, but more consequentially his values were cast in the finest of moulds. He studied at Hartley College, Point Pedro, and was one of the four outstanding Hartleyites to study engineering, get their first class and join the academia. Shan was preceded by Prof. A. Thurairajah, easily Sri Lanka’s most gifted academic engineering mind, and was followed by David Guanaratnam and A.S. Rajendra. All of them did Civil Engineering, and years later Hartley would send a new pair of outstanding students, M. Sritharan and K. Ramathas who would go on to become highly accomplished Electrical Engineers.

Shan graduated in 1962 with First Class Honours and may have been one of a very few if not the only first class that year. Shan worked for a short while at the Ceylon Electricity Board before proceeding to Cambridge for postgraduate studies specializing in Structures. His dissertation on the Ultimate Strength of Encased Beams is listed in the publications of the Cambridge Structures Group. He returned to his job at CEB and then joined the Faculty in 1967. At that time, Shan may have been one of the more senior lecturers in Structures after Milton Amaratunga who too passed away late last year in Southampton, England.

When we were students in the early 1970s, there was an academic debate at the Faculty as to whether a university or specific faculties should give greater priority to teaching or research. Shan was on the side of teaching and he was quite open about it in his classes. He would supplement his lectures with cyclostyled sheets of notes and the students naturally loved it. It was also a time when Shan and many of his colleagues were young bachelors at Peradeniya, and their lives as academic bachelors have been delightfully recounted in a number of online circulations.

The cross-sectional camaraderie at the Faculty in those days is well captured in one of the photographs taken at Shan’s wedding at Point Pedro, in 1974, which too has been doing the rounds and which I have inserted above. Flanking Shan and his bride Kalamathy, from Left to Right are, M. Dhanendran, Nandana Rambukwella, K. Jeyapalan, Wickrama Bahu Karunaratne, A.S. Rajendra, Lal Tennekoon, Tusit Weerasooria, and R. Srikantha. Sadly, Rambukwella, Karunaratne (Bahu), Tennekoon and now Shan himself, are no longer with us.

Like other faculty members, Shan kept contact with his former students turned practising engineers and they would reach out to him to solicit his expertise in their projects. In the early 1980s, when I was working as Resident Project Manager with my Peradeniya contemporaries, JM Samoon and K. Balasundram, at the Hanthana Housing Scheme undertaken by the National Development Housing Authority (NHDA), Shan was one of the project consultants helping us with concrete technology involving mix design and in situ strength testing using the testing facilities at the Faculty.

The Hanthana Team Looking back, the Hanthana housing scheme construction was the engineering externalization of the architectural imaginings of Tanya Iousova and Suren Wickremesinghe, for building houses on hill slopes without flattening the hills. The project involved the construction of hundreds of housing units with supporting infrastructure comprising roads and drainage, water supply and sanitary, and electricity distribution using underground cables. Tanya & Suren Wickremasinghe were the Architects with an Italian construction company as contractors.

To their credit, Tanya and Suren assembled quite a team of Consulting Engineers that was a cross-section of E’Fac alumni, viz., Siripala Kodikkara and Siripala Jayasinghe (Contract Administration); Prof. Thurairajah (Foundations & Soil Mechanics); S.A. Karunaratne (Structures); V. Shanmuganyagam (Concrete Technology); Neville Kottagama and DLO Mendis (Roads & Drainage); K. Suntharalingam (Water Supply & Sanitary); and Chris Ratnayake (Electrical).

As esoteric gossip goes, DLO Mendis had an informal periodization of engineering graduates, identifying them as either Before-Thurai or After-Thurai, centered on 1957 – the year Prof. Thurairajah graduated with supreme distinction and went on to do groundbreaking theoretical research in Soil Mechanics at Cambridge. Of the Hanthana consultant team, Neville Kottagama and DLO Mendis were before Thurai by six years, Shan was five years after, and all the others came later. Sadly though, only Tanya and Chris are with us today from the 1980s group named above.

After Hanthana came 1983 when all hell broke loose and hundreds of professionals and their families were forced to leave Sri Lanka. Shan left Peradeniya and joined Nanyang Technological University in Singapore, encouraged by his Cambridge contemporaries from Singapore. He taught at Nanyang for twelve years (1984-1996) before moving to Canada with his wife and three sons who were by then ready for university education.

All three children have done exceptionally well in their studies and professional careers. The oldest, Dhanansayan, is a Medical Doctor and a Professor at the University of Wisconsin School of Medicine and Public Health, in Madison, United States. That was where India’s Jayaprakash Narayan and Sri Lanka’s Philip Gunawardena had their university education a hundred years ago.

The younger two sons took to Engineering. The second son, Kalaichelvan, is Program Manager at Creation Technologies, an award-winning global electronics manufacturing service provider. And the youngest, Dhaksayan, is the Chief Information Officer (CIO) at the Toronto Transit Commission (TTC), which is North America’s third-largest urban transit system.

All three have done their parents proud and Shan would have been gratified to see them achieve exemplary success in their chosen fields. A first class Engineer and a first class teacher, Shan was also a great father and a loving grandfather. As we remember Professor Shanmuganyagam, we extend our thoughts and sympathies to his beloved wife Kalamathy, his sons and their young families

Cannavarella: Estate once owned by OEG with a heritage since 1880

Published

on

Established in 1880, Cannavarella Estate stands among the most historically significant plantations in Sri Lanka, carrying a legacy that intertwines agricultural heritage, colonial transitions and modern development. Its story begins with the cultivation of cinchona, a medicinal bark used to produce quinine, which is a vital treatment for malaria at the time, introduced when coffee estates across the island were failing.

Under the ownership of Messrs Macfarlane, Cannavarella rapidly gained a reputation for producing cinchona at ideal elevations between 4,000 and 5,000 feet above sea level. At that time, the estate spanned around 750 acres and played a pivotal role in the island’s shift from coffee to alternative plantation crops during the late 19th century.

A transformative chapter began when Christopher B. Smith purchased the property and unified several surrounding estates- Moussagolla, Cannavarella, East Gowerakelle, and Naminacooly- into what became known as the Cannavarella Group. This amalgamation created a vast holding of approximately 1,800 acres. By 1915, nearly 1,512 acres of this extent were cultivated in tea, marking the estate’s full transition from cinchona to the crop that would define its identity for generations.

The Group was managed by the Eastern Produce and Estates Company from 1915 until 1964, after which stewardship passed successively to Walker & Sons Company Ltd, and then to George Steuart Company Ltd by 1969.

A defining moment in the estate’s history arrived in 1971 when Sir Oliver Goonetilleke, former Governor General of Ceylon, acquired the estate. Under his ownership, it came under the London-based company Ceyover Ltd., a name derived from “Cey” for Ceylon and “Over” for Oliver.

The estate remained under private ownership until the nationalization wave of 1975, during which Cannavarella was brought under the Janatha Estates Development Board (JEDB). For nearly two decades it was managed under government purview until the plantation sector was re-privatised in 1992.

Sir Oliver Goonetilleke

Thereafter, Cannavarella Estate moved under the management of Namunukula Plantations Limited, first through BC Plantation Services, then under John Keells Holdings’ Keells Plantation Management Services and eventually under the ownership of Richard Pieris & Company PLC, where it continues today as part of the Arpico Plantations portfolio.

Blending heritage, landscape and community

Situated along the northeastern slopes of the scenic Kabralla-Moussagolla range and bordering the Namunukula mountain range, Cannavarella Estate spans a total extent of 800 hectares. Its six divisions rise across elevations from 910 to 1,320 metres above sea level, creating a landscape ideal for cultivating premium high-grown tea. Of the total land area, 351 hectares are dedicated to mature tea, while 54 hectares consist of VP tea, representing 16 % of the estate.

Among its most remarkable features are fields containing seedling tea bushes more than a century old, living symbols of Sri Lanka’s plantation legacy that continue to thrive across the slopes. The estate is also home to the origin of the Menik River, which begins its journey in the Moussagolla Division, adding an ecological richness to Cannavarella’s natural environment.

Cannavarella’s history of leadership reflects broader transformations within the plantation industry. The last English superintendent, Mr. Charles Edwards, oversaw the estate during the final phase of British management. In 1972, he was succeeded by Franklin Jacob, who became the first Sri Lankan superintendent of the Cannavarella Group, marking a shift toward local leadership and expertise in plantation management.

Development within Cannavarella Estate has never been confined to agriculture alone. Over the past decade, the estate has strengthened its emphasis on community care, diversification and improving living conditions for its workers. In 2022, coffee planting was initiated in Fields 7 and 8 of the NKU Division, covering 2.5 hectares as part of a broader effort to introduce alternative revenue streams while complementing tea cultivation.

The estate’s commitment to early childhood development is reflected in the initiation of a morning meal programme across all Child Development Centres from 2025, ensuring that children receive nutritious meals each day. A newly constructed Child Development Centre in the EGK Division, completed in 2020, now offers modern facilities including a play area, study room and kitchen, symbolizing the estate’s dedication to nurturing the next generation. In 2015, a housing scheme consisting of 23 new homes was completed and handed over to workers in the CVE Division, significantly improving quality of life and providing families with safer, more stable living environments.

A future built on stability and renewal

Cannavarella Estate is preparing to undertake one of its most important social development initiatives. A major housing programme has been proposed to relocate 69 families currently residing in landslide-prone areas of the Moussagolla Division. Supported by the Indian Housing Programme, this effort aims to provide secure, sustainable housing in safer terrain, ensuring long-term stability for vulnerable families and reducing disaster risk in the region.

Across its history, Cannavarella Estate has remained a landscape shaped both by the land and the people who call it home. Cannavarella continues to honour its roots while building a modern legacy that uplifts both the estate and its people. (Planters Association news release)

From the Lecture Hall to the Global Market: How Sri Lankan students are mastering the “Gig Economy”

Published

on

Image : Courtesy South China Morning Post

Have you ever wondered how a university student, between heavy textbooks and late-night study sessions, manages to earn a professional income in US dollars? It sounds like a dream, but for thousands of Sri Lankans, it’s becoming a daily reality through online freelancing.

A recent study published in the Ianna Journal of Interdisciplinary Studies has pulled back the curtain on this digital revolution. By interviewing 21 successful student freelancers across Sri Lanka, researchers have mapped out exactly what it takes to turn a laptop and an internet connection into a thriving career.

The Rise of the “Earn-as-you-learn” Era

In Sri Lanka, the number of online freelancers has exploded from about 20,000 in 2016 to over 150,000 today. While our traditional education system often focuses on preparing students for 9-to-5 office jobs , these students are diving into the “Gig Economy” a digital marketplace where they sell specific skills, like graphic design or programming, to clients all over the world.

The Secret Sauce for Success

So, what makes some students succeed while others struggle? The research found that it isn’t just about being good at coding or design. Success comes down to six “Core Pillars”:

· A Growth Mindset: The digital world moves fast. Successful students don’t just learn one skill; they are constantly updating themselves to ensure they don’t become “outdated”

· The Balancing Act:

How do they handle exams and clients? They don’t use a magic wand; they use strict time management. Many work late into the night (from 6 p.m. to midnight) to accommodate international time zones.

· The Power of “Hello”:

Since most clients are in the USA or UK, strong English and clear communication are vital. It’s about more than just talking; it’s about negotiating prices and building trust.

· Proactive Problem Solving:

Successful freelancers don’t wait for things to go wrong. They update their clients regularly and fix issues before they become headaches.

Why This Matters for Sri Lanka

Right now, our universities don’t always teach “how to be a freelancer”. This study suggests that if we integrate freelancing modules and mentorship into our degree programs, we could significantly reduce graduate unemployment. It’s a way for students to gain financial independence and bring much-needed foreign currency into our economy while still in school.

You Can Do It Too

If you’re a student (or the parent of one), the message is clear: the global market is open for business. You don’t need to wait for graduation to start your career. With a bit of flexibility, a willingness to keep learning, and a proactive attitude, you can transition from a learner to an earner.

The Research Team Behind the Study

This groundbreaking research was conducted by a dedicated team from the Department of Business Management at the SLIIT Business School (Sri Lanka Institute of Information Technology). The authors of the study include:

· Lihini Niranjana Dasanayaka

· Thuvindu Bimsara Madanayake

· Kalana Gimantha Jayasekara

· Thilina Dinidu Illepperuma

· Ruwanthika Chandrasiri

· Gayan Bandara
