Hydropower Performance

India’s hydro generation AGAIN below 10% in 2017-18

In 2016-17, for the first time in independent India’s history, hydropower generation from large hydropower projects in India fell below 10% of total electricity generation. In 2017-18, for which the Central Electricity Authority figures have just became available, the trend has continued, with proportion of electricity produced by large hydropower projects going further down. This percentage is in terms of actual generation (measured as Million or Billion Units[i]) and not installed capacity (measured in Mega Watts).

As per recently released figures for the year ending on March 31, 2018, the power generation from large hydropower projects (CEA only reports large hydro generation) in 2017-18 was 126.18 BU, when total power generation in India (including renewables generation of 101.84 BU, but excluding Bhutan imports of 4.78 BU) was 1303.37 BU, hence hydropower generation in 2017-18 was 9.68%, for the second year in a row going below 10% of total generation. In previous year (2016-17), the proportion was 9.90% (hydropower generation of 122.38 BU compared to total power generation (including renewable generation of 81.97 BU but excluding Bhutan imports of 5.62 BU) of 1236.39 BU).

Looking at the trends, the total hydropower generation is likely to remain below 10% of total power generation in coming many years, since while hydropower generation is still going up, the total generation is growing at much faster pace. In fact, the total renewables generation is likely to overtake the total hydropower generation in 2018-19 or the next year.

Stranded Large Hydro projects Two major reasons for this declining proportion of hydropower generation are: diminishing generation of existing hydropower projects in India[ii] (see the graph below) and large hydropower projects becoming more and more unviable in spite of all the propaganda of they being clean, green, cheap and renewable sources of power. As power minister of India stated in the Parliament recently[iii], at least 15 large hydro projects (NHPC chief says 40 HEPs need bailout package, see below) with capacity close to 6000 MW remains stranded in India. These projects have received all the statutory clearances, but are not going forward due to financial or technical or inter-state or legal issues or inept implementation or agitation. The power ministry[iv] should stop wondering how to bail out unviable large hydropower projects through bailout packages of Rs 16000 crores and more. They need to understand that when solar and wind power is available at price below Rs 3 per unit, why is there attempt to push large hydro whose cost is universally over Rs 5-6 per unit at least for first few decades.

India’s non optimal operation of hydropower projects India’s Power Minister, on June 23, 2017 released FOLD-POSOCO Report[v] on Operational Analysis for Optimization of Hydro Resources & facilitating Renewable Integration in India. The report concludes: “The report concludes that there is scope for additional peaking support of 3000-5000 MW with equivalent amount of backing down in off-peak hours from the existing hydro power stations. The gain from the optimized dispatch on annual basis is estimated to be 5 paisa per unit which is equivalent to earning of the order of Rs. 600 crores per year at all India level.” This clearly shows that India’s hydropower capacities are performing far below its optimum peaking power generation potential, while we are not even assessing the social and environmental impacts of peaking mode of power generation.

Niti Ayog’s flawed NEP The Niti Ayog (which has replaced the erstwhile planning commission) has on June 27, 2017 come out[vi] with a Draft National Energy Policy and invited comments by July 14, 2017[vii]. The draft seems flawed at the outset. For example, on p 42 (top) the draft NEP says: “Arunachal Pradesh alone is touted to have a potential of 50,000 MW of hydro-power potential of which only 98 MW has been developed till March, 2016.” This is TOTALLY WRONG. Just one project, namely Ranganadi Hydropower project in Arunachal Pradesh has capacity of 405 MW, as per CEA’s generation report for March 2016[viii], the month that NEP refers to. Its projection of reaching 61000 MW large hydro capacity by 2022 is also clearly flawed, the current hydro installed capacity is less than 45300 MW and there is no possibility of reaching even 50 000 MW by 2022, leave aside 61 000 MW. The target of reaching 74 or 92 GW by 2040 is similarly neither viable nor desirable. It projects that generation from large hydro would reach 214 BU by 2022 is similarly neither possible nor necessary, current annual generation is hardly 126 BU.

The final National Electricity Plan[ix] released by the  Central Electricity Authority in March 2018 continues to provide misleading picture and pushes for more incentives to make the unviable hydropower projects viable.

Centre for Financial Accountability has been doing analysis of govt push for hydropower projects and trends of financing Hydropower projects, see: http://www.cenfa.org/finance/big-push-for-the-development-of-hydropower-in-india/ and http://www.cenfa.org/blog/the-trends-in-hydro-power-financing-in-india/.

In conclusion The writing is clearly on the dam walls: In stead of hankering for unviable[x] and destructive large hydro capacities, India needs to pay attention to optimizing generation from existing hydro and explore the possibilities of installing hydro projects at 97% of India’s existing large dams where there is no hydro component. We also need to first manage our peak hours’ power demand and optimize generation during such demands, only after assessing and addressing the social and environmental impacts of peaking hour power generation from large hydro projects. Else we will be destroying more rivers and their biodiversity and livelihoods of people dependent on such rivers, while throwing more money into the pockets of contractors and other vested interests. The Ministry of Environment and Forests and its Expert Appraisal Committee on River Valley Projects too needs take this opportunity to improve our pathetic environmental governance rather than keep pushing more clearances for projects that are only likely to remain paper horses.

END NOTES:

[i] One Unit equals one Kilowatt hour, which is the power generated when 1 KW of installed capacity runs for one hour. The units are actually consumable and provide the correct picture of power available for consumption.
