Started as the Tata Hydroelectric Power Supply Company in 1911, it is an amalgamation of two entities: Tata Hydroelectric Power Supply Company and Andhra Valley Power Supply Company (1916).Today Tata Power Company Limited is India’s largest private sector electricity generating company with an installed generation capacity of over 2300 MW. The Company has emerged as a pioneer in the Indian power sector, with a track record of performance, customer care and sustained growth. Tata Power has a presence in all areas of power sector generation (thermal, hydro, solar and wind) transmission and distribution. Inspired by a powerful vision, the founders of Tata Power pioneered the generation of electricity in India with the commissioning of India’s first large hydro-electric project in 1915 . The thermal power stations of the company are located at Trombay in Mumbai, Jojobera in Jharkhand and Belgaum in Karnataka. The hydro stations are located in the Western Ghats of Maharashtra and the wind farm in Ahmednagar.
The Company has been a front-runner in introducing state-of-the-art power technologies. Among its achievements, the company has to its credit the installation of India’s first 500 MW unit at Trombay, the first 150 MW pumped storage unit at Bhira, and a flue gas desulphurization plant for pollution control at Trombay. An optimum mix of hydel and thermal capacity enables the company to supply power at competitive tariffs to its customers. At 2.4% the Company's transmission & distribution losses are among the lowest in the country. Tata Power having served Mumbai’s consumers for over nine decades has since spread its footprint across the country and abroad. Outside Mumbai, the company now has generation capacities in the States of Jharkhand and Karnataka and a Distribution Company in Delhi.
The Distribution joint venture with the Government of Delhi called the “North Delhi Power Limited” (NDPL), has met with considerable success. This joint venture serves over 800,000 consumers (in a population of 4.5 million) spread over in an area of 510 km² and has a peak load of 1050 MW. Since its formation in 2002 the company has launched a series of technological improvements for upgrading reliability and other consumer services. NDPL as a joint venture company has to serve the North and North Delhi from the distribution point of view. Initially an agreement was signed for five years between the Delhi government and Tata Power, which will be reviewed in July 2005. Now as per information received that the contract again has been implemented to next four years. NDPL has achieved a great success in cutting down the losses from 51% to 28% in span of five years.
The Company has also executed several overseas projects in the Middle East, Africa and South East Asia. Of particular interest are the Jebel Ali ‘G’ station (4 x 100 MW + desalination plant) in Dubai, Al-Khobar II (5 x 150 MW + desalination plant) and Jeddah III (4 x 64 MW + desalination plant) in Saudi Arabia, Shuwaikh (5 x 50 MW) in Kuwait, EHV substations in UAE and Algeria, and power plant operation and maintenance contracts in Iran and Saudi Arabia.
In a ‘first of its kind’ project, Tata Power has entered into a 51:49 joint venture with PowerGrid Corporation of India for the 1200 km Tala transmission project. The joint venture is India’s first transmission project to be executed with public-private partnership.
Tata Power has also bagged contract for building 4000 MW power plant at Mundra. One unique aspect of this project is that for the first time in India a 4000MW power plant is being built utilizing one large construction project; all other large projects have always involved stage construction.
