Future of the energy industry: Renewables
There is a need for statistics and data
Aker Solutions Vice President and Key Accountant Manager Harry Kulasinghe noted that the country has the fundamentals such as good companies, leisure sector and schooling for oil and gas development when compared to some other countries. So what do we need to do to monetise the gaps?
“We need to have better statistics and data,” Kulasinghe said. “My view would be we are a relatively poor country so we need to somehow increase the quality of data so that the international oil companies can have a better understanding of the amount of reserves we have.”
By doing so, the industry will be able to assess the how much there is and find out whether it is big enough for LNG or if it needs to be moved domestic or in other avenues. The country will then have to see what the domestic market is like and what do we do with the additional resources.
Having his own energy company, the advice Kulasinghe could give is that the better option is to convert to electricity and export. “Electricity could be generated on the vessels themselves which is quite competitive,” we said.
No future for fossil, make way for renewable and ocean energy
During the next 20 years, the world will have to stop the burning of fossil fuel, despite having reserves to last another 40-50 years due to the environmental impact it has such as climate change and global warming, more so than the depreciating resources.
Energy Forum Executive Director Asoka Abeygunawardane expressed that with the exponential growth currently experiencing, it is not practicable to keep at fossil fuel for more than 20 years for the betterment of human civilisation in the long term.
What then is the next step? His answer was renewable energy, energy efficiency and sustainable lifestyles.
Some of the key questions governing the use of renewable energy are: How much do we have; Do we have enough? How costly is the exercise? Sri Lanka has enough renewable energy resources to cater to the existing demand. “Being a tropical country we have enough solar, we have good potential for wind, under bio mass we have enough land to grow integrating the existing culture and harvest,” Abeygunawardane observed.
Over and above, the major renewable energy Sri Lanka has is ocean energy which has not been tapped yet. “We have stable current, stable waves and enough energy in the waves. There is great potential there.”
Cost-wise when taking in to account the life span of a renewable energy plant, the costs are competitive. Renewable energy technologies are already cheaper than oil as well, he said. “Thinking of lifespan I can assure that renewable is cheaper than coal. In most instances, in most of the renewable technologies except for bio mass there is no fuel cost involved and hence is cheaper.” What is needed is storage and the energy could be stored using pump water storage.
“My firm belief is that renewable energy is the future. We need to use fossil fuel to establish the renewable energy infrastructure.”
In the long run Sri Lanka can be in the forefront in the world by pioneering ocean energy consumption as renewable energy, Abeygunawardane said. “We can then sell the technology.” Sri Lanka is already selling mini hydro technology to other countries.
Feasibility studies carried out by CEB for efficient energy
CEB Generation Planning Chief Engineering Buddhika Samarasekara noted that at present Sri Lanka’s energy composition is made up 40% of hydro, 50% thermal and 10% Non Conventional Renewable Energy (NCRE) which includes mini hydro and solar power.
He said that feasibility studies are now being carried out by CEB regarding the introduction of LNG as an option for Sri Lanka, studying in detail the impact on environment as well as the economic aspect.
“We are also carrying out preparation of a Renewable Master Plan, because even though there is a lot of potential in wind, solar, dendro, mini hydro, we must look at the intermittent nature as well as the transmission network limitations.” This Renewable Master Plan will come as part of the Long Term Energy Generation Expansion Plan of the CEB.
“We are already carrying out the feasibility study for pump storage power plants as well,” Samarasekara said. Three locations have already been identified for this; but this will only come in to the system post 2022, perhaps around 2025. “We are giving due consideration to the environmental conditions of coal power plants as we are now considering the high efficiency clean coal technologies.”
Feasibility studies are also being carried out regarding the construction of high efficiency clean coal power plant. Samarasekara said: “At present we want to find out a good energy mix, that doesn’t burden the people as well.” Right now coal is the cheapest source and has to be used efficiently and in an environmentally friendly manner.
“We are also carrying out demand side management activities and looking at shifting of peak demand to off-peak, mainly by using pump-storage as well as some other methods, which will save our high cost generation plants during the peak,” Samarasekara observed.
Sri Lanka has a long way to go to achieve renewable energy target
The 2005 Renewable Energy Policies has noted that a minimum of 15% of energy generation of power sector should come from renewable, which should reach and 20% by 2020, Wind Force Ltd. Director/CEO Manjula Perera said. “Unfortunately we are only at 6.3% today. It is a long way to go considering there is only six years more.”
The 20% mark has come through studies done by international scientists who have found out that energy production around the world as of now should be converted to 20% renewable. “Whether we like it or not, we have to go for renewable for the wellbeing of human beings.”
Looking at the long-term CEB plan, Perera stated that from here onwards it is all about coal.
As of today the private sector is contributing 360 mega watts to the national grid and the potential for the future is 300 mw more from small dendros, with a huge wind potential of close to 5000 mw at least, “but our system cannot take that 5,000 mw because it is a small system. The only possibility to make use of this is the link between India and Sri Lanka. Then we are connected to a very big network and there are no limitations.”
Another key parameter is cost. In 2012 what CEB paid to non-conventional renewable energy was Rs. 12.18 as average cost of energy, which is less than the CEB selling price. In 2013 this was at Rs.16.70, but was still less than the CEB selling price of Rs. 19.
Samarasekara noted that the general perception is that coal is the cheapest. “Capital cost of Norochcholai Coal Power Plant is coming to Rs. 15 and the agreement signed for Sampur is Rs. 17.84, which makes renewable cheaper still. We won’t say avoid coal power plants but due consideration should be given for renewable which is available in the country.” |
