Drizzle, Cloudy Skies Cause Drop in Solar Power Generation


Light drizzles and cloudy skies in the southern region of Tamil Nadu in recent days have caused a drop in solar energy generation.

The generation from solar panels in potential areas under Tirunelveli Circle of Non-conventional Energy Sources, TANGEDCO, such as Kamuthi, Aruppukottai, Tiruchuli, Virudhunagar, Thoothukudi and Tirunelveli normally yields 900 MW to 1,000 MW every day.

However, over the last two days, the output has gone down to 600 MW to 700 MW, sources told The Hindu here on Tuesday. After the onset of the Southwest monsoon, the catchment areas in Tamil Nadu and parts of the Western Ghats started receiving rain.

Wind energy generation also dropped to some extent in the wake of the rainfall. The energy sourced from wind turbines recorded an output of around 2,500 MW on Monday. On Tuesday, however, it dwindled to 2,100 MW. Four days ago, 2,600 MW of electricity was generated through wind power.

In July, the wind power generation will go up to 3,000 MW. The daily average of wind power generation in June touched 2,000 MW with the aid of turbines in windmill stations from Aralvaimozhi, Shencottah, Muppandal, Kayathar, Eppodhumvendran, Tenkasi, Radhapuram, Vadakankulam and Kudankulam under the Tirunelveli Circle, sources said.

More importantly, the electricity consumption has come down considerably. Last week, around 15,000 MW of electricity was consumed daily in Tamil Nadu, but now it is below 13,000 MW.

At present, four units, including first, second, third and fifth of Tuticorin Thermal Power Station (TTPS), each with a 210 MW capacity, are operational.

The first unit, which remains on standby since Friday, was brought into service at 4.33 a.m. on Tuesday.

Since the generation from one unit of Kudankulam Nuclear Power station came to a halt, the load despatch centre authorities instructed to resume generation from the first thermal power unit, sources said.
