In an unprecedented move, only two power generating units of Tuticorin Thermal Power Station (TTPS) are functional.
The other three units of the TTPS have been kept in a standby mode as the authorities were asked not to produce electricity, following the lowered demand for electricity.
It is a unique situation in the history of the TTPS as units one, three and four have been kept in a standby mode for over a week since last Saturday, sources told The Hindu here on Sunday.
Currently, the production is on in the second and the fifth units, each with a production capacity of 210 MW.
Wind-powered energy production is at an optimum level, and it has brought down the demand for production of coal-fired energy from conventional thermal power station. This situation has led to a drastic reduction in coal usage in the thermal power station.
On a daily average, four tonnes of coal is required for production from a unit. A coal stock of five lakh tonnes is maintained in the plant now. To avoid any combustion in the stockyard, which could be caused by rising temperature, coal is being watered.
Sources said 25 per cent of the coal used in the plant was imported from Indonesia, and the rest was sourced domestically.
Sources from Non-Conventional Energy Source, TANGEDCO, Tirunelveli Circle, said 2,150 MW of wind energy was generated until noon on Sunday. On Saturday, this circle saw a production of 2,193 MW. The electricity production from wind mills did not go below 2000 MW in the last four or five days. On August 4, the production touched 2,215 MW.
Further, sources said a 1,800 Mega Volt Ampere (MVA) wind power substation, the highest capacity ever in Tamil Nadu, is likely to be commissioned at Kanarpatti near Kayathar either by September end or in the middle of October.
Besides, works were in progress to establish a 1030 MVA wind power substation at Thennampatti near Ottanatham, sources added.
