Dam Good!




One thing that strikes you as you travel to Kugti is the number of hydro-electric projects that have sprung up all over the Chamba Valley.

From the moment you leave the Punjab plains and enter Himachal Pradesh, you see power projects of assorted shapes and sizes all along the route. Many of them are the conventional, small-scale run-of-the-river projects where you have a small dam blocking the river and the resulting resorvoir being used to generate electricity. Others are a lot more complex, and the only sign of their existence is the tunnels that have been bored through the mountains, to divert waters into long pipes that feed hidden turbines.

It may not make the river look cleaner or prettier but it certainly helps the local population access one thing that makes the winter months more bearable: electricity. Thanks to projects like these, Himachal Pradesh is able to generate more than 8500MW of electricity which it is able sell to states located downstream.

Perhaps the largest player in this valley is the National Hydro Power Corp (NHPC), a central public-sector enterprise that has set up some of the largest power plants on the Ravi river, such as the Chamera-I and Chamera-II projects. Having decided to settle down for a long haul, NHPC has numerous office/staff/residential complexes all along the Chamba valley, commanding some of the best views in this district!

Private players are not too far behind. GMR and Lanco too have a growing presence here with the former represented by deep green container-box offices set up all along the road up to Holi.



Now, which are the small HEPs located along the road to Kugti?

Solar: Upstream and Downstream



Amazing things are happening in India's renewable energy market - especially solar power.

Yesterday , it was reported that at an auction of a 250 MW capacity plant at Bhadla (Rajasthan), South Africa’s Phelan Energy Group and Avaada Power bid INR 2.62 (USD 0.04) per kilowatt-hour (kWh) to win contracts to build capacities of 50MW and 100MW, respectively, at Adani Renewable Energy Park Rajasthan Ltd. This is a new record low. The bidding wars seem to have now reached a point where experts are wondering if it is commercially viable to produce produce power at these rates.

If the unit price is surprising, so is the sheer scale of the new 'solar farms' that are coming up. The current world record the world's largest solar project in a single location is now held by Adani's 648-megawatt Kamuthi plant (near Marurai, Tamil Nadu), which went online in September, 2016. The second largest solar plant, the Topaz Solar Farm in California, has a capacity of 550 megawatts.



For a country that located in the tropics, India has a huge potential for switching over to solar energy. Consider these facts -

  • The solar  radiation incident over India is equal to 4–7 kWh per square meter per day with an annual radiation ranging from 1200–2300 kWh per square meter. 
  • It has an average of 250–300 clear sunny days and  2300–3200 hours  of sun shine per  year. 
  • India's electricity needs can be met on a total land area of 3000 km2  which  is  equal  to  0.1%  of  total  land  in  the country 
  • Currently  India is  generating  4.59%  of solar energy  of  total  produced  renewable  energy  installed capacity in India


Over the past few years, thanks to a concerted push by the government, India has quadrupled its solar-generation capacity from 2,650 MW on 26 May 2014 to 12,289 MW in 10 March 2017.  Yet, behind all these impressive numbers, fact remains that present and future growth is completely hinged on the import of equipment from China. In 2015-16, the value of imported solar cells and modules tripled to $2.34 billion, with China accounting for 83 per cent ( $1.9 billion).

Despite having a dedicated Ministry for New and Renewable Energy (MNRE) for the past 15 years, why is it that India has not been able to it own supply chains? Why is it that Indian manufacturers have no access to domestic upstream raw material supplies of poly-silicon and wafers?

According to a KPMG report (2015), India has not been able to create economies of scale in solar manufacturing, mainly due to insufficient government support - loans, tax holidays, subsidized utility services, easy access to land and technology support.

Is that a rather simplistic view?
