Serlui-B Hydropower Project, Mizoram, India


Serlui-B Hydropower Project is the largest hydro plant in Mizoram. The site is near Bilkhawthlir Village in Kolasib district. The DPR was approved in Feb 1999 and a turnkey contract was awarded to BHEL and Mecon in Dec 2003. Serlui-B has a 293m long, 51m high earthfill dam a 415m headrace tunnel, a 135m pressure tunnel, and a semi-underground powerhouse. The project cost Rs 191cr [1] Construction began in 1998 but it was halted in 2004 because of 'unfavourable geological conditions at the dam site, technical reasons, high compensation for crops and law and order situation'. In 2011, the project cost was revised to Rs 913.23 crore, almost triple its original estimate of Rs 369 [2] Nearly 5,100 villagers of Ratu, Mawchar, Saipum, Palsang, N. Khawdungsei, Serzawl, Lungmuat, Bukpui, Saiphai, Hlimen, Darlawn, Khawruhlian, N Chaltlang, Nisapui and Thingtherh will be affected by the dam [2]. The Hydel Project submerged Builum village and the affected villagers were rehabilitated on a new site Bawktlang near Kolasib [4] The Serlui B project has the dubious distinction of creating the state's first 'dam refugees' who are still fighting for proper rehabilitation and in case of Tuirial project, the people and experts are questioning its legality as no public hearing was ever held. Experts said the affected villagers of Tuirial could move court [2].

Project Details and Actors
Project DetailsSerlui B is located about 12 kilometres from Bilkhawthlir, a small village on the NH-54. The Hydel Project has three units, each with a capacity to generate 4 MW of power and the estimated cost of completion is expected to be about Rs. 191 crores. As of now about 95 percent of the work has been completed and about 174 crores have been spent so far. The Dam of the Hydel Project is called an ‘earthen dam’ since earth is used for the dam unlike other hydel projects in Mizoram. The dam is 51.3 metres high from the river bed, 293 metres long, 8 metres narrow at the top and 394.2 metres wide at the bottom.

The 12 MW power hence added will be a boon for the power starved state whose power requirement is about 107 MW, out of which 77 MW and 52 MW are the deficits at the highest and lowest respectively. The cost per unit has been estimated at about Rs. 3.69 per unit. On the 12th of Dec 2003, the Government of Mizoram, Bharat Heavy Electricals Limited (BHEL) and Metallurgical Electrical Consultant India Ltd. (MECON) signed agreements for the construction. Major components of the works were awarded to BHEL-MECON Consortium on turnkey basis and the work commenced in November 2004. Project is a State Sector Project; all the power produced will be utilized by Mizoram, unlike Centrally funded power projects where the States’ share are just a meagre 12 percent [4]

Do you consider this as a success?Not Sure
Why? Explain briefly.1. Although there was a tripartite multi-disciplinary committee for Tuirial project was notified to 'oversee effective implementation of suggested safeguards measures,' on ecology, forestry, and wildlife. But nothing is mentioned about safeguards for people against the impact of the dam.

2.The project received environment clearance in 1995 and experts questioned if it was still valid [2].

3.According to Environment Support Group, a premier lawyers' group on environmental law in India, the validity of an environment clearance expires in five years if the project does not continue.

4.Central Bureau of Investigation (CBI) charges nine persons, including relatives of former chief minister a and officials recently for their role in a compensation scam. The scam was unearthed after a PIL was filed by anti-corruption watchdog SOSA (Society for Social Action). Gauhati High Court in April 2010 ordered a probe into the scam. The CBI investigation revealed that compensation was paid to fictitious landowners [2].

5. The villagers alleged that irregularities in the assessment of compensation claims which was because the officials made the assessment without visiting the site. [5]
