To satisfy the energy needs of the State, Tamil Nadu Generation and Distribution Corporation Limited has an installed capacity of 18732.78 MW which includes TANGEDCO owned State projects, share from the Central Generating Stations(CGS) and Private Power Purchase.
Other than this, the State has installations in renewable energy sources like wind mill, solar, biomass and cogeneration up to 10,479.61 MW.
To meet the ever-increasing energy demand in the coming years, TANGEDCO has proposed new generation for the next 5 years. TANGEDCO has fully exploited the hydroelectric potential available in the state. However, to balance the excess power available during off peak hours and to tide over the peak hour shortage, a Pumped storage scheme in Kundah for 500 MW has been proposed.
TANGEDCO has also proposed to establish small hydroelectric projects of capacity less than 25 MW in the run of river scheme with total capacity of 110 MW.
Power generation, especially coal based power plants are prone to have an adverse impact on the environment. Presently TANGEDCO has four major coal based Thermal Power Stations with a total capacity of 4060 MW and four gas based power plants with a total capacity of 516 MW. TANGEDCO recognizes its social obligation and is conscious of the importance of prevention of degradation of the environment due to its Thermal Stations More..
