Power hunger - the energy future:

Looking to Sun, wind and water

Renewable energy is the only option to overcome power cuts and blackouts. Chairman of the Sri Lanka Sustainable Energy Authority(SLSEA) Keerthi Wickramaratne was optimistic that the only way out of this issue was to make a gradual switch to renewable sources of energy.

He said although initial costs in setting up renewable energy power plants were high, it is as costly as some claim. However, he agreed that an immediate switch was not possible. "Nevertheless, it is feasible through upgrading our systems" he said.

Wickramaratne said with assistance from developed countries, a switch to renewable energy was a possibility. "Computerised systems and other costs will arise but switching to renewable sources was a positive move, he said.

"Solar and wind power were the best options for renewable energy sources in Sri Lanka. Solar power is a good option" he said.

"If we increase the use of solar power, then costs will decrease, while in the long-term it will be cheaper and most importantly, it is environment-friendly" he said. However, Wickramaratne said storage of solar power might be a problem due to various issues.


He said offshore sea currents were a viable option "But we have not yet developed it to be used as a renewable energy source," he added.

While options for renewable energy are many, at present power generation through non-conventional renewable energy such as solar according to the Central Bank Report remains at 9.9 percent unchanged from the previous year and only generates a mere 1217 GWh annually.

With Sri Lanka facing a number of blackouts last month due to various technical reasons the Ceylon Electricity Board (CEB) faced, and the coal- powered Norochcholai power plant failing yet again, concerns among the public and the authorities were raised on the reliability of the national power supply, while alternative energy is a much-discussed topic.

According to the Central Bank Report of 2014, the total generation of electricity in Sri Lanka has increased by 3.9 per cent to 12,357 GWh up from 11,898 GWh in 2013. Currently while 69 per cent of the power supply is generated by the CEB, this amount keeps dropping annually, with the remainder being purchased from independent power suppliers.

Chairman of the Ceylon Electricity Board(CEB) Anura Wijepala said over 50 percent of Sri Lanka's power supply was through renewable sources, with hydro power being the main source which provides up to 50.3 percent of the electricity generated.

"There are only a few countries which generate power from renewable energy and we are one such" he said, adding that in the modern day, not even developed countries produce energy from such sources. According to Wijepala, countries such as Nepal and Bhutan generate electricity through hydropower and provided the facility to a select number of consumers and not to the whole country" he said.


The Central Bank Report points out that hydro power generation during the year became difficult, due to the prevailing drought in Sri Lanka, once again proving without any doubt, the importance of cheap and alternative energy options that can provide a more sustainable power supply, while meeting the demand of its 5.7 million consumers in the island.

"Renewable energy was of significant importance in the modern day," Strategic Enterprise Management Agency Asoka Abeygunawardana said. Due to the environmental impact, fossil fuel use should be phased out by 2050. Coal power has no future and does not serve Sri Lanka any purpose to set up fossil fuel infrastructure to generate power, he said.

"Economic costs, environmental costs and social costs of imported coal were expensive whereas other renewable sources were much cheaper, making renewable energy the best alternative for the country," he said.

Minister of Finance Ravi Karunanayake noted in his 2016 Budget speech renewable energy was one of the key areas of potential investment of over Rs 2 billion. The Minister encouraged homeowners to opt for solar power, with costs being a qualified deduction for tax purposes while also emphasising the potential of non-conventional renewable energy, such as wind and solar.

Minister Karunanayake encouraged the CEB to partner with private companies to harness such sources to provide cheaper energy to consumers and meet the domestic requirement.

Also on a positive note, the Central Bank Report stated that 12 mini hydro power projects, three wind power plants, one biomass power plant and one dendro power project were commissioned, showing attempts to move towards renewable energy. The CEB has also signed contracts for 42 non-conventional renewable energy projects.

The Sri Lanka Sustainable Energy Authority identified potential wind power in Mannar being able to generate wind power of up to 375 MW.

With these steps bringing hope, the question remains as to whether Sri Lanka could switch to renewable energy, which experts claim to be the answer to the energy woes in Sri Lanka.

The CEB Chairman was hopeful and said, "It is 100 percent feasible" adding that a switch to renewable energy was possible albeit not immediately, if Sri Lanka looks towards ways of storing the energy. This, he said, was an expensive exercise.
