Sampoor Power Station; dead in the water? environmental impact case study

The Ministry of Power and Renewable Energy has decided not to go ahead with the construction of the Sampur Coal Power plant, see Daily Mirror report 14/09 in what many will see as a victory for environmentalists. 

In November 2015 The Sunday Times also reported that the new power plant earmarked for Sampur near Trincomalee was a non starter. The main reasons given were that:

  • the plant has failed to meet the Environmental Impact Assessment criteria laid down
  • Sampur has been earmarked for 800 returning IDP Tamil families (internally displaced persons) who do not wish to see a large power station built on land so close to them.

On the face of it you can see why.

The Sampur plant

The proposal is to build a 500 megawatt coal fired power station on the east coast at Sampur across the bay from Trincomalee.

The power station is proposed to be built on 500 acres of land currently sectioned off as a high security zone by the Sri Lankan Navy but was formerly land belonging to the local Tamil population driven from their lands during the final months of the war which ended in 2009.

It will be a joint venture with the National Thermal Power Company of India using low grade coal imported from India.

The Case against 
  1. Damage to the marine environment of Shell Bay: Shell Bay is home to 56 hard coral species, 160 of coral associated fish species and many other invertebrates including the rare giant clam. The Mahaweli Ganga ( river) also exits to the sea nearby bringing a high nutrient concentration and all these factors contribute to make Trincomalee Bay a unique ecosystem with high biodiversity ranging from tiny organisms to large whales.

Negative impacts will likely include the following:

  • when operational the discharge of cooling water from the power station will raise the water temperature of Shell Bay by 4 degrees celsius; sufficient to result in bleaching of the coral which will then die
  • contamination of the water from sulphur. and mercury as a result of the burning of coal
  • chlorine  will be used to clean the water and if discharged without treating, it can first impact on tiny organisms like planktons and can have a major impact on the food chain

2. Air Pollution

If the plant uses imported Indian coal (coal with a high ash content) then engineers suggest that significant amounts of air pollution will occur locally resulting in:

  • acid rain (from nitrogen oxide and sulphur oxide  carbon monoxide and carbon dioxide being pumped into the atmosphere)
  • significant amounts of ash/dust particles and unburnt hydro carbons which can cause lung damage
  • ash and sludge which will have to be buried in large landfill sites

3.  Social Issues

The new government have already begun the proceed of resettling tamil families back into the Sampur area and, as the Sunday Times recently pointed out:

“the unfavourable impact of a coal power plant has been a major worry for the people who are waiting to come back to their land in Sampur. They fear their precious agricultural lands are contaminated and the air they breathe would be polluted.” ...

… not without reason you might think.

It is also suggested in some areas that the land set aside for the plant in fact belongs to displaced families and so should not be used for industrial development.

4.  Political Issues

  • The Tamil National Alliance are firmly against the project and see this ( the high security zone) as an a attempt to keep out the Tamil population. They allege:

” a hidden agenda to the project to permanently evict Tamils from the Muttur east region.”

  • The restoration of lands taken from the Tamils features high on the agenda of many external governments,
  • At the same time  Sri Lanka is under pressure from foreign governments to show it is making progress in this aspect of post war reconciliation and in the field of human rights

So for these reasons it was politically expedient to reconsider siting the plant at Sampur.

5.  Power exports

Some of the power would have been sent via a new grid to Southern India; Sri Lanka would not get the full benefit of the new generating capacity although it would suffer all of the disadvantages outlined above.

So you might think the case against is overwhelming. But it is not that simple

The Case For
  1.  Sri Lanka needs power

The Sri Lankan economy is growing at around 7% annually; fairly impressive when compared to the  low growth economies of the developed world. However, continued growth in the manufacturing and business sector is going to drive up energy demand, particularly electricity demand. Some are even predicting that Sri Lanka will be in energy deficit by 2017.

current projections (see page 282) suggest that electricity demand is likely to increase by around 5% per annum but meeting this target may prove difficult and expensive given that the Island is not self sufficient in terms of energy production.

The country has no domestic production of coal, crude oil, or natural gas, and as a result all the fossil fuel demand is met through imports.

At the moment that means oil which now accounts for just over 50% of power generation.

BUT relying on oil-fired power comes at a heavy price pushing up the cost of electricity to the consumer.

(How lucky then that the recent fall in oil prices allowed the government to reduce electricity prices and the cost of petrol.. trouble is it won’t last. Prices will go up again!)

Sri Lanka needs to move from a dependence on imported oil is an urgent issue for Sri Lanka’s power sector to address, but options are limited:

  • hydro electric power is already at close to full capacity
  • nuclear power as an option is not under serious consideration yet and in any case would be way too expensive and take too long to get up and running
  • solar/wind/geothermal/wave power; are all in their infancy

Which means the only viable option for developing large “base line” energy supplies in the short term, is to build new coal fired power stations.

So far one major plant has been built on the west coast at Norochchalai which will generate around 17% of Sri Lanka’s energy.

The Norochchalai  Power Plant

However it won’t be enough; That is why the Government entered into an agreement with  to build a large 500 mega watt power plant at Sampur near Trincomalee.

2. Cost:

It is argued that the current site incurs the lowest development cost; environmental protection and pollution mitigation measures plus consideration of alternative site would add to the cost already standing at $512 million

3.  Politics

The the Sri Lankan government agreed to partner an Indian company in the development of this power project. It has already “disappointed” the Indian authorities by not co-building the Norochchalai complex with them but going with the Chinese design and build. Reneging on this agreement could further damage relations between the two countries

Something has to happen

The question is: what happens now? Sri Lanka cannot build sustainable economic growth on the back of rising oil imports, nor can it squeeze more energy from existing renewables like HEP.

Nuclear power is not an option either.

That leaves wind and solar as alternatives, unless of course the government simply decide to build a coal fired plant somewhere else (maybe less environmentally sensitive?)

The energy clock is ticking and if the plant is not going to be built in Sampur, energy will have to come from another source; and with major growth projects such as the Megapolis plan for Western Province already under way the decision on how to generate more energy needs to come soon.
