Sterlite has been awarded three projects for building power transmission systems (lines and substations) in India, as a Developer, on a Build Own Operate Maintain ("BOOM") basis. For these projects, Sterlite would undertake the designing, financing and construction and maintenance of the transmission systems for concession periods ranging from 25 to 35 years.

Once the power transmission system is built and is available for use, Sterlite would be paid a quoted transmission tariff for the entire concession period by various users of the transmission systems. This arrangement is similar to a take or pay arrangement.

Sterlite's portfolio of three projects aggregate to a total value of about
Rs. 40 Billion. These transmission systems would evacuate and transmit power through a network of about 2200 km of transmission lines and 2 substations; in the states of Maharashtra, Gujarat, Madhya Pradesh, Chhattisgarh, West Bengal, Bihar and Assam.

In the next decade, India needs to spend over Rs. 1400 Billion on transmission systems and Sterlite believes the BOOM model will be the preferred model and that it is well positioned to become a market leader in this sector.
