Professor of SASTRA University Thanjavur, Muralisachithanadam, wrote to me about his lecture on Pumped storage power plant posted in YouTube... on the notes taken from my blog. I was really happy when he mailed me more than couple of emails to let me watch the lecture… I was quite out of idea when I wrote about the Pumped storage power plant? But it seems I have been writing about it indirectly through my post on Kadamparai Dam in Valparai.
The professor narrates the subject simply to understand anyone in Tamil and I am so grateful for his note of thanks and picture on me at the end of his lecture (video below). Kadamparai power project is an engineering marvel and manmade wonder! The unique about this hydro power project was the power plant is situated deep inside the hill, travelling 6km into a tunnel that cut through a single mountain rock. I have nothing to say rather feeling wonder, how incredible our engineers are to make successful a project design that borrowed from Germany which failed at the level of execution and operation there.
I visited the Kadamparai site in 2008, but we couldn’t get permission to go inside the tunnel to visit the power house which is 7 storeys inside the tunnel! I was happy at least getting chance to make visit to the site and learning its amazing process. The power generated here were in two modes: In the generation mode, the machines will be operated to cater the peak hour demand for full load, depending on the storage level of Kadamparai Dam and the Upper Aliyar Dam. In the Pump Mode, the machines will pump the water from Upper Aliyar Dam to Kadamparai Dam during night hours on grid frequency above 49.4 Hz and heavy under drawl of UI from central pool.
I really thank the professor for making an impression among students about the Pumped storage power plant and encouraging them to take notes from my blog. The Kadamparai pumped storage power plant is a marvelous project that not many know about its efficiency (even not many engineers aware of it) which is first of its kind in India. It is also one of the highly protected sites, surrounded by wildlife activities and tribal settlement and getting permission is toughest… even if not visited, leaning about this project is must.
