Electricity generation in Tamil Nadu until about 1908 was confined to a few tiny plants in Tea Estates run on water power and to a small hydro electric station at Kattery near Coonoor. The Government Electricity department was created in 1927.
The Pykara Hydro electric Power Station was constructed by Sir John G. Henry Howard, a British Engineer and the first Chief Electrical Engineer of the then Composite Madras State Electricity Department and commissioned in 1933 with an original installed capacity of 70 MW.
The Tamil Nadu Electricity Board was constituted with effect from 1 July 1957 under the Electricity Supply Act 1948 and came to be known as “The Madras State Electricity Board” with Padmashri V.P. Appadurai appointed as Chief Engineer (Electricity). The first thermal power plant was commissioned during 1971 at Ennore, Chennai with its first unit of 60 MW capacity.
Naphtha based gas station of 10 MW capacity was commissioned at Narimanam during 1991-92. TNEB simultaneously ventured into wind generation and 120 units with a total capacity of 19.355 MW was commissioned in the period 1986-93. In 1992, the power sector was thrown open for private participation and the first independent power project was established by GMR Vasavi at Basin Bridge,Chennai.
Today TNEB has grown into a giant organization having a installed capacity of 10,122 MW and serving a consumer base of about 2 crore consumers
The Government of India has planned to give "Power for all by 2012". To achieve this, Tamil Nadu Electricity Board is making progress in Generation, Transmission and Distribution sector. TNEB has completed the electrification of all villages and towns in the state and is also progressing towards electrification of all households.
To satisfy the energy needs of the state, TamilNadu Electricity Board has a total installed capacity of 10,214 MW which includes State, Central share and Independent power producers. Other than this, the state has installations in renewable energy sources like windmill up to 4300 MW. Due to the astronomical increase in energy demand in the last few years, the state has a deficit of power which is estimated to be around 11.9% as on Feb 2009.To meet the ever-increasing energy demand in the coming years, TNEB has proposed new generation projects for the next 5 years.
TNEB has a total of 1202 substations with HT and EHT lines to a length of 1,63,883 km. The voltage levels in use in TNEB are 400KV,230 KV,110 KV, 66 KV,33 KV, 22 KV and 11 KV. In order to evacuate bulk power from one region to another region, there is a more scope for enhancing transmission capability to 765 KV level and setting up of 800 KV High Voltage DC system. The Government of India has approved nondiscriminatory open access for the transmission system .The Government of Tamil Nadu has also permitted third party sale of power produced by IPPs, CPPs & other private power producers through short term Intra-State open access to HT consumers within Tamil Nadu.
TNEB has a consumer base of about 200 lakh consumers. 100% rural electrification has been achieved. Per Capita consumption of Tamilnadu is 1000 units.To achieve the goal of electrification of all households, the Government has launched the Rajiv Gandhi Grameen Vidyutikaran Yojana (RGGVY) scheme. Where grid connectivity is not feasible or not cost effective, Decentralised Distributed Generation is permitted.
To achieve reliable and quality power supply and minimise the loss of energy, MOP/GOI has launched the Restructured APDRP scheme under 11th five year plan.
Government of Tamil Nadu has accorded an in principle approval for the re-organisation of TNEB by the establishment of a holding company, by the name TNEB Ltd and two subsidiary companies, namely Tamil Nadu Transmission Corporation Ltd (TANTRANSCO) and Tamil Nadu Generation and Distribution Corporation Ltd (TANGEDCO) with the stipulation that the above mentioned companies shall be fully owned by Government . The Govt. has also constituted a Steering Committee to finalise the transfer scheme for the re-organisation of Board under section 131 of the Electricity Act, 2003.
India has the world's fifth largest wind power industry, with an installed wind power capacity of 9,587 MW.
The Power Engineers Hand Book published by TNEB Engineers Association is well recognized among the practicing Electrical Engineers of the country. The Hand Book has its origin in the year 1947. The sixth enlarged version was released in 2002.
