The company said that it had learned of two fatalities among subcontractors that were not reported at its partly-owned project being built in the state of Himachal Pradesh.
It added that the total number of deaths on the run-of-river project is 11 since construction began in 2006, and there have been 81 personal injuries requiring treatment at hospital or an out-patient clinic.
The 192MW hydro power project is being developed by the joint venture company Malana Power, in which SN Power has a 43% stake. The principal shareholder is NLJ Bhilwara Group (45%) and the balance is owned by the International Finance Corporation (IFC).
The underreporting of fatalities emerged from an audit in mid-November. SN Power said it had not been given full and complete information from the project company.
Allain Duhangan has an underground powerhouse at the confluence of the Allain and Duhangan rivers, which are tributaries of the Beas river. The design head is 833m and the powerhouse holds two 96MW vertical axis Pelton turbines. The project budget is US$220M.
SN Power is equally owned by Statkraft and Norfund, an investment body. There is agreement in place for the utility to raise its holding to 60%.
