The 51:49 joint venture with PowerGrid Corporation of India for the 1,200 km Tala Transmission Project: Powerlinks Transmission Limited (Powerlinks) is India's first transmission project to be executed as a Public-Private-Partnership. Powerlinks transmit power from the Bhutan based Tala Hydroelectric Project (in Nilgiri, West Bengal), through the Eastern/North-Eastern Region of India to Mandola in Uttar Pradesh (near New Delhi) a total distance of 1,200 km. Ten States (West Bengal, Bihar, Jharkhand, Sikkim, Punjab, Haryana, Uttar Pradesh, Jammu & Kashmir, and Delhi) benefit from this project, which transfers about 3000 MW of regional power. Maintaining an average availability of 99.7%, the project is an important link in the national power grid and is the first inter-state transmission project that has been implemented through the Public-Private-Partnership route. Powerlinks has also balanced the ratio between thermal power and hydel power in the eastern region of India.
