Hydro pump storage to play vital role in grid reliability

‘Currently most schemes are in the PFR stage. We expect the hydro power market to move in 2019’

Although the Indian power sector has grown substantially, according Neelav Samrat De, who works with a reputable company dealing with the supply of electromechanical systems and services for hydropower plants, most of the areas of hydro energy potential is yet to be tapped, as lack of clearances and no fresh funds have stalled the development of the sector.

What’s the state of Indian power sector right now?
The Indian power sector has grown substantially and today, with an installed capacity of 3.45 GW, the country is well poised to meet energy demands for the years to come. However, it would be noteworthy to mention that the current focus is primarily on solar power. With a mammoth renewable energy capacity addition target of 175 GW until 2021, it seems impractical now. Solar tariff bidding had touched a low of ₹2.4 per unit, which was the zenith of things. Things have stabilised to an extent with the government increasing duty on Chinese photovoltaic cells.

Currently, the power sector does not contribute significantly to the economy as the sector itself is in shackles. Thermal plants have not been able to close on coal linkages while IPPs are still deep in debt. The smaller players and SPVs formed to develop and build projects have now mostly queued up at the NCLT door.

Hydropower seems to have almost fizzled out.
Areas of hydropower potential still remain untapped with either lack of clearances or no fresh funds being infused in new and existing projects. Around 40 stressed hydro assets are yet to see reprieve from their current state of nothingness. Barring solar and wind power, the rest of the sector is pretty much looking into uncertainty unless important revival steps are taken.

What’s the role of electrification in India’s growth?
The demand for electrification has always been on the top of the agenda for India’s growth. The current government’s Deen Dayal Upadhyaya Gram Jyoti Yojana has helped in bringing electricity to most of India’s villages. The scheme has provided feeder separation, strengthening of sub-transmission and distribution network, metering, electrification of villages, and setting up micro-grid and off-grid distribution networks.

With greater thrust expected from India’s manufacturing sector in the near future, electrification needs will come handy to tackle industries, especially small and medium enterprises. However, as per reports, it seems that only 7.3 per cent of India’s rural area is electrified. No doubt, a massive accomplishment, but a closer look at what constitutes “electrified” reveals how much further India has to go. With high targets yet to be achieved, the demand for power is still high and it is, but obvious, that electrification will drive India’s growth in terms of economy, jobs and wellbeing.

Are there any initiatives that helped hydropower sector?

Role of hydropower in India’s economic growth
Hydropower power is one of the greenest and cleanest sources of electrical energy. It plays an important role in employment, local area development, providing free power to local community, and in some cases also share premium with village folklore. Though India’s hydro share is only 14 per cent of the total 3.5 GW of installed capacity, it offers the best return on equity in the long term. This can be seen from existing plants where power is sold at ₹0.60 per unit.

What’s the state of hydro energy sector?
The hydro sector is faring well below other energy sources such as solar and wind. We do not see any movement of projects being undertaken by central government undertakings, least to mention the concerned IPPs. Except IWT projects in Jammu & Kashmir, there is no movement in projects in Arunachal Pradesh, Himachal Pradesh and Uttaranchal.

A lack of will, fatigue and funds has almost stalled the sector. However, there is a market for after-sales, with most hydro plants being over 25 years of age. Hence, projects in the south of India are mainly undergoing modernisation, renovation and even uprating.
This is the only silver lining on the horizon at the moment.

What is being done to achieve power targets?
India could possibly achieve about 76 per cent of the target of having 175 GW of renewable power generation capacity by 2022, according to Wood Mackenzie. Around 100 GW will be added through solar while 75 GW from wind. Despite the myriad challenges, this could well be managed. However, there isn’t much expectation from the thermal and hydro sectors within this period.

What does the future hold for the hydro sector?
As and when the Hydro Policy is in place, we could expect to see changes. With the renewable energy power capacity addition being added into the grid, the need for hydro pump storage schemes will play a major role in grid reliability and stability. We could expect movement in PSPs by mid-2019. Currently most schemes are in the PFR stage. We expect the hydro power market to move in 2019.
