The state of Tamil Nadu is located in the southern tip of India which is one of the Renewable rich states. This state was pioneer in bringing the grid connected wind energy to the country. The demonstration grid connected wind farm was established by the State Government, with the Danish funding, way back during early 90��?s. The successful commissioning of grid connected 120 windmills for a capacity of 19 MW, attracted private investors in this sector. Since then, there was no looking back and still Tamil Nadu has the highest RE capacity in India. This was made possible not only due high wind potential of our state but also due to the conducive polices of our State Government. The installed capacity of Renewable Energy (RE) power in our state, as of now, is around 9.7 GW (wind ��? 7.6 GW, solar ��? 1.1 GW, others ��? around 1 GW), out43 GW of the country��?s capacity i.e., which is around 23% country��?s capacity. In the meanwhile, India has envisaged an ambitious target of more than 175 GW of renewable power to be installed in the country by the year 2022. Of this, wind energy account for 60 GW and solar energy for 100 GW. Out of 29 states in India, only 7 to 8 states are RE rich. That means the entire addition fixed by the government has to be derived from these states only. In our state the installed capacity of RE power is about 35% of the total installed capacity of our state. When the % was less earlier, the wind power was absorbed fully. As the RE capacity increases, managing the grid has become a challenging job, while trying to absorb the entire wind energy. More over in Tamil Nadu, the wind is seasonal and available during May to September and even during the season, during intraday, the fluctuation is very high. For example, it varies from 2000 MW to 100 MW. Since we do not have adequate spinning reserve and our based load is met only from thermal generation, the sudden variation in wind cannot be managed.
