R.Okay. Vishnoi, Chairman and Managing Director, THDC India Restricted (THDCIL), spoke to Renewable Watch in regards to the efficiency of the hydropower phase over the previous one 12 months, in addition to the important thing points and options to handle them. He additionally mentioned his high priorities and plans for the corporate. Excerpts…
What’s your evaluation of the hydropower phase’s efficiency prior to now 12 months or so?
Hydropower continues to be one of the crucial dependable sources of peak energy, owing to its inherent operational flexibility and speedy response capabilities. Hydro tasks additionally present a number of advantages, together with consuming water provide, irrigation, flood management, tourism, fisheries and employment technology. Although there have been common capability additions within the hydro sector through the previous few years, the share of hydropower within the Indian energy sector has been declining because of the comparatively massive capability additions of thermal and different renewable vitality tasks, notably photo voltaic and wind. The Indian authorities has renewed its deal with hydropower, notably storage-based tasks, recognising their essential function in making certain water safety amid altering precipitation patterns. With the approaching up of large-capacity renewable vitality tasks, hydro pumped storage tasks (PSPs) are poised to play an important function within the vitality transition by storing the excess energy from variable renewable vitality tasks and supplying it throughout peak demand or non-solar hours, making certain a secure and versatile energy provide.
The whole exploitable capability identified for giant hydropower tasks within the nation is 133 GW. Of this, roughly 48 GW is presently in operation, and one other 13 GW is below lively development throughout numerous states, whereas 18 GW of hydroelectric tasks (HEPs) are below survey and investigation. Over the previous 12 months, capability addition within the hydro sector has not been very vital – just one GW of hydroelectric capability has been added to the grid, comprising 800 MW from the central sector and 200 MW from the state sector.
There was a development of about 10 per cent in hydropower technology over the previous 12 months, and a major improve is anticipated through the coming years because of the commissioning of varied stalled tasks and coverage interventions by the Ministry of Energy.
As per projections, the full large-hydro capability is anticipated to extend from round 48 GW presently to roughly 67 GW by 2031-32. A complete of 66 PSPs have been recognized throughout the nation, comprising 17 on-river tasks and 49 off-river tasks. Final 12 months, the Central Electrical energy Authority (CEA) accredited the detailed mission reviews (DPRs) of six PSPs totalling roughly 7.5 GW in document time.
With robust coverage assist and funding, India’s hydropower sector is on a revival trajectory and is ready to play a essential function in facilitating vitality safety, local weather resilience and renewable vitality integration.
What are the steps wanted to speed up the phase’s development?
To fast-track the expansion of India’s hydropower sector, the federal government has carried out focused coverage reforms to ease procedural delays and enhance mission viability. Key measures embrace shortened timelines for DPR approvals, streamlined environmental clearances and monetary exemptions equivalent to waivers on transmission costs, electrical energy and water cess. Assist has additionally been prolonged for enabling infrastructure equivalent to devoted transmission traces, ropeways and rail sidings. Undertaking allotments have been made extra versatile, permitting central PSUs to take up tasks via nomination, aggressive bidding and even self-identification.
To additional strengthen the hydropower sector, further coverage and structural interventions are crucial. The uniform adoption of central pointers throughout states is required to make sure regulatory consistency. A strong market mechanism for PSPs should be developed to monetise grid providers equivalent to voltage assist and ramping functionality.
Given the inherently lengthy gestation intervals and excessive capital necessities of hydropower tasks, you will need to streamline your complete clearance course of – technical, administrative, forest, wildlife and environmental – at each the central and state ranges. A unified and time-bound approval framework can be essential in accelerating mission implementation.
To enhance the bankability of hydropower investments, monetary establishments ought to provide long-term, concessional loans in recognition of hydropower’s renewable standing. Such assist, coupled with prolonged reimbursement intervals, will decrease tariffs and enhance mission attractiveness for each builders and energy purchasers.
What have been THDCIL’s key enterprise and development highlights prior to now one 12 months?
