Small hydropower industry debunks negative theories

  • Deforestation and impact on aquatic life negligible 

  • Compliance among industry uncompromising

Sri Lanka’s small hydropower industry came out strongly against negative theories and myths that plague the industry, despite it showing tangible evidence that such negativities have no foundation. Small Hydropower Developers Association (SHPA) Secretary Prabath Wickramasinghe said the SHP industry is faced with numerous problems due to issues created by NGOs in particular, none of which are factual. “There are delays in obtaining various government approvals due to unreasonable and baseless allegations by these NGOs and reluctance of government officials to give their consent due to pressures exerted on them by these interested parties.”

He lists some of the issues the SHPA has been grappling with. Firstly, that mini-hydropowers (MHPs) harm fish in streams and negatively impact the eco system. “This theory has no scientific evidence as no post audit has been conducted on the subject to 17-6quantify such impacts. While construction is in progress, there will admittedly be an impact which is a hallmark of development, but this is relatively low when compared with other development projects.” He adds that existing regulations imposed by the Department of Agriculture and the CEA are all complied with, including the height of the weir being less than 3m and sufficient environmental flow to be released to the downstream of the weir for the protection of aquatic life. 

“Freshwater streams are impacted much more by other factors, including the use of weedicides, pesticides and fertiliser by farmers which are washed into streams, the dumping of garbage into waterbodies and use of dynamite to catch fish,” says Wickramasinghe. Another factor he brings up is that the impact from MHPs are localised with the overall impact to aquatic life, if any, is less than 1%, given that of the 15,000 km of rivers and streams in Sri Lanka, MHPs use less than 200 km, which is just 1.3%.

There’s also the allegation that MHPs clear forest land for construction, which Wickramasinghe says is a negligible area. “Of the 180 MHPs, only approximately 15 are in forest areas, utilising just one hectare or less; this from a forest cover of 1.86 million hectares. Other development projects including plantations, shifting cultivation, firewood collection, house construction, infrastructure and roads took 490,000 hectares of forest, while MHPs used only 15 hectares which is 0.0031%. It is apparent, that 99.997% of the deforestation that has taken place due to development is not related to our industry.” He adds that even to bring the impact up to 1%, 4,885 projects would have to be located in forest lands, where currently only 15 are operating. 

Wickramasinghe also highlights that there are no MHPs in environmentally sensitive areas, as approvals are not granted for projects in these locations.

He reiterates that each MHP is a legal body, incorporated in Sri Lanka with offices located at the site and most often in Colombo. “Our teams are all responsible individuals working for responsible organisations. It is easy then for these companies to be targeted by NGOs, publicising baseless information. For example, in the mass destruction of fish, can NGOs take action against farmers for using fertiliser and pesticides that run into streams or the illegal dynamite fishing? They won’t because of the huge backlash in the case of farmers and the inability to find those responsible for dynamite fishing. But when it comes to a company, it is very easy to point fingers with baseless information.”

The MHP industry in Sri Lanka, since its inception in 1996, now has a total of 169 projects producing 337.77 MW and has been named by the World Bank as the best performing project of its kind. It has also become the sought after role model by countries in Africa and South Asia as well as the World Bank. “There has been a saving of Rs. 19 billion on foreign exchange given the industry’s contribution to the national grid with a generation of 4,000 in direct employment for 4,000 and 5,000 indirectly,” says Wickramasinghe. 

Thus, Wickramasinghe states the naysayers should look at the industry objectively, both from the fact that the industry is contributing not only foreign exchange via projects being emulated overseas and by contributing to the national grid by reducing the quantity of imported fossil fuel being used, but also the fact that it produces a cleaner, greener energy that is ecologically sustainable.
