Chimneys

If ever you take a train out of Chennai Central, you cannot miss this trio. Well, yes, at night time you will not be able to see the colours so clearly, but the chimneys are lit up, so they are not easy to miss. A generation or so ago, these chimneys weren't around, but you would know that you are crossing the Basin Bridge power station because of their predecessors - massive concrete structures, which looked pretty much like chimneys, as you can see from this picture.

The Basin Bridge power station was modernised by GMR and was commissioned in 1998. Since then, it has been supplying about 200MW of electricity to the state electricity board. GMR claims that it does not use any water from the city, but treats the city's sewage to generate the water it needs for its operations. They boast a 75% recovery rate from the sewage - I am not sure if that is a high benchmark, or just regular operations. 

So, the next time you go out of the Chennai Central station, don't forget to say goodbye to these chimneys!

Power holiday

It is always good to be in Chennai, but once in a while, one is slightly embarassed about the 'privileges' the city enjoys. Embarassed not because those privileges are undeserved, but because the context of those privileges needs to be explained to non-Chennaiites who bristle at the 'unfair' treatment they receive. Right now, it is the issue of power-cuts; normally a power-neutral state, Tamil Nadu has been hit by a combination of factors leading to power availability falling by almost 20%. Power thefts and transmission losses are constants; the official line is that erratic rainfall and lower availability of uranium for the nuclear plant at Kalpakkam are the main causes for the current shortfall.

This shortfall has led to a power cut being imposed all across the state. Factories have been asked to declare an additional off-day each week, as a 'power holiday'. Rolling blackouts have been imposed in all areas. The first such power cut regime came into effect in mid-July; within a week, it was withdrawn for most consumers. Since yesterday, the cuts are back with a vengeance - Chennai will have blackouts for 1.5 hours each day; the suburbs of Chennai will be powerless for 3 hours a day. The rest of the state, though has to suffer through 5 hours without electricity. That creates strong resentment against the city dwellers and there are several demands for more 'equitable power cuts'. But with Chennai generating roughly 4.5% of India's GDP (and about 40% of Tamil Nadu's), longer power cuts in the city will have a huge knock-on effect - and a longer recovery time post the crisis.

The picture is of a substation in the city, just after a new transformer was installed a few weeks ago. Maybe this one too needs a good spell of rain for it to start working!
