Mini hydel causing macro scars in the Western Ghats

There is a rush to flood the Western Ghats in Karnataka with mini hydel projects, each with an installed capacity of around 25 MW. Promoted by public sector Karnataka Renewable Energy Development Limited and built by private players, as many as 836 mini hydel plants with a combined capacity of over 4,000 MW have been under various stages of implementation, from consideration to construction. Numerous such projects shall soon dot the rivers like Netravathi, Kumaradhra and Gundias on Dakshin Kannada map. Reports indicate that nearly 108 mini hydel projects are at various stages of completion.

Since these can be built without undergoing any environment impact assessment and consequently do not need environment clearance as well as mandatory public hearing, there is literally a ‘gold rush’ to scar (see picture) the picturesque Western Ghats with such power units. Though one would imagine these units to be non-obstructive and non-offensive in nature, dams to create the desired head discharge are at times as high as 10 meters.

Simply assuming that a mini hydel project will be green and clean by default could indeed be untrue. Sample this: the 24.75 MW MHP by AMR in Perla Village and another 24.75 MW MHP at Shemburi by Ritwick Energy near Mangalore are in reality on big project worth 50 MW whereas as per the Project Design Document submitted to UNFCCC for claiming Carbon Credits, both were 'separate' mini projects. Much to everybody’s surprise, Netravathi river has been dammed with huge submerge upstream of the structure, sudden release from which had drowned three youths last year.

Same is the case with the Maruthi Power Gen dams in Hassan, which were shown at two different locations on paper (to avoid forest clearance) but were being executed as one huge structure on ground. The construction and tunneling activity has caused extensive damage to forests and wildlife habitat.  On the other hand, Kukke I Project near Hosmata is unique as it will not only submerge houses and endanger a critically endangered plant that has recently been rediscovered in the area but will submerge part of another MHP unit upstream as well.

Since mini hydel projects do not need mandatory public hearing, an informal public hearing was organised under the aegis of the Save Western Ghats Movement by Prakruti and SANDRP on Aug 4-5, 2012 at Kukke Subramanya, a small temple town near the origin of the river Kumaradhara in Dakshin Kannada district. As many as 60 affected farmers, fishermen, activists, researchers and scientists took part in the discussions and issued a ‘Subramanya Declaration’ that called for greater regulation of the sector alongside punitive action for those violating the norms.

Mini hydel projects can be clean, green and welcome provided the sector is regulated and efforts made to involve local population in planning and implementation of such schemes with a caveat that the communities have access to power generated through MHPs in their area.
