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, Tamil Nadu Electricity Board has a total installed capacity of 10,214 MW which includes Central share and Independent Power Producers. Other than this, the state has installations in renewable energy sources like windmill, Bios mass and Cogeneration up to 5586 MW. As of now, the total installed capacity in Tamil Nadu is 15800 MW.

To meet the ever-increasing energy demand in the coming years, TNEB has proposed new generation projects for the next 5 years. TNEB has fully exploited the hydroelectric potential available in the state. However, to tide over the peak hour shortage, 3 Pumped storage schemes totalling 1200 MW in Kundah (500 MW), Mettur(500 MW) and Vellimalai(200 MW) are available.
Transmission sector of TNEB consists of the following network infrastucture
*.HT and EHT or a total length of 1.69 Lakhs Kms.
*. A total of 1345 substations .
*. 95 Substations in and around Chennai have been provided with SCADA and have been integrated into *. Chennai Distribution and control center (DCC)
TNEB has one State Load Dispatch Centre at Chennai and 3 Sub LDCs at Chennai, Madurai and Erode.
The transmission network expansion is aimed at evolving a national power grid to facilitate free flow of power across regional boundaries, raising the transmission voltage from 230 kV to 400 kV level. In order to evacuate bulk power from one region to another region, there is scope for enhancing the transmission capability to 765 KV level. Tamil Nadu Electricity Board has taken up the indigenous erection of 400 KV substations and lines . Establishment of 765 KV transmission lines is also under investigation.
The Government of India has approved nondiscriminatory open access to the transmission system to all generators for injecting power and to any consumer to carry the power from the point of injection to his load. To augment the power supply, 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 as it will provide an incentive to the generators within the State to produce to their full capacity.
An efficient distribution network is needed for effectively utilizing the energy that is generated.TNEB has an efficient network that has grown over the years.
Growth over 51 Years (From 1957)
Consumer base from 4.3 Lakhs to about 212 Lakhs
Number of Distribution Transformers from 3773 to 1.92 Lakhs
Length of LT lines from 13,055 kms to 5.38 Lakhs Kms
Peak demand from 172 MW to 10180 MW
Per Capita consumption from 21 units to 1080 units
Number of electrified towns, villages and hamlets from 1813 to 63956
