- 2. BENEFITS OF HYDRO POWER
• Renewable: energy security, no fuel shortage
• Clean: no CO2 emissions
• Yet predictable (as against wind)
• Peaking support (as against other renewables): even RoR
schemes provide peaking support
Very cheap in the long run
• Development of remote areas.
• Source of revenue for States without other natural
resources, and with locational disadvantages
• IN INDIA, THERMAL:HYDRO RATION OF 60:40 CONSIDERED
IDEAL

• PERCENTAGE OF HYDRO HAS COME DOWN FROM 45% IN
1970 TO 20% IN 2012.
• A number of hydro players have announced withdrawal
• 11th Five Year Plan achievement 6111 MW against target of
15,627 MW
• UTILISATION OF POTENTIAL IS ONLY 44,859 MW OUT OF
1,57,000 (28%) (China: almost 50%)
• IN ADDITION, 90,000 MW OF PUMPED STORAGE YET TO BE
TAPPED
WHAT IS WORSE, WE ARE NOT EVEN PLANNING FOR
CORRECTING THIS

- 9. Peaking – a neglected area
• Recent Grid disturbances have shown importance
of peaking power, both seasonal as well as di-
urnal
• Gas:
Dependent on imorts
Wild fluctuations in availability, tariff
Already a large capacity is stranded
• Oil:
Most expensive, but today most prevalent:
generators

- 10. KNOWN UNKNOWNS
• Geological surprises
• Land acquisition
• Rehabilitation & Resettlement
• Forest clearance
• Environment clearance
• Agitations
• Poor road infrastructure
• Lack of access to data e.g. hydrological data
ALL THESE DIFFICULTIES MAKE HYDRO A RISKY PROPOSITION
Copyright © 2010 Jindal Steel & Power Ltd.
- 11. LARGE HYDRO – AN ORPHAN
• Renewable, but yet not counted as renewable
• No RPO/REC
• No Feed-in Tariff
• No excise/customs duty benefit (except for mega projects)
• No accelerated depreciation
• Why is small hydro ‘new and renewable’, but not large
hydro? Because it is off-grid/de-centralised?
Then why is ‘large solar’ or ‘large wind’ new and
renewable?
Copyright © 2010 Jindal Steel & Power Ltd.
- 12. LARGE HYDRO AN ORPHAN:
POWER PROCUREMENT
• Peaking power does not figure in long term power
purchase plans of utilities. Nor do regulators insist on it
• And why should they, when they can over-draw at will?
• No utility ties up power years in advance. Long gestation
projects such as hydro suffer
• Consequently, hydro has to compete with thermal in
power procurement. May suffer if tariff, particularly first
year tariff, is higher than thermal
• Invariably, fuel costs rise faster than the indices for
comparison
Copyright © 2010 Jindal Steel & Power Ltd.
- 13. LARGE HYDRO – AN ORPHAN:
MEGA POWER PROJECT BENEFITS
• Excise/customs duty exemption only for equipment, but
not for civil part
• 75% of hydro project costs are for civil, whereas only 10-
15%% project costs of thermal projects are for civil
• Tariff impact of this difference – 10 to 15 p
Copyright © 2010 Jindal Steel & Power Ltd.
- 14. LARGE HYDRO – AN ORPHAN:
TARIFF SETTING
• Construction period 4 years for thermal, but 6 to 8 years
for hydro. ROE not allowed during construction: Low IRR
• Many projects have to pay upfront charges to States,
which carry no return
• Project preparation longer and more expensive than in
thermal (DPR, Land acquisition, R & R etc)
• Approach road construction also a heavy initial burden
• Tariffs do not reflect peaking benefits
Copyright © 2010 Jindal Steel & Power Ltd.
- 15. FINANCE
• A large part of tariff of a thermal plant is fuel, whereas
most of the tariff of a hydro plant is accounted for by
capital cost
• Longer gestation period adds to the IDC burden
• Hydro projects are therefore more sensitive to terms of
finance
• Lack of long-term finance makes tariff front-loaded,
comparing unfavourably with initial tariffs of thermal
plants
The very long life of hydro projects does not get due
recognition

- 16. ATTITUDE OF STATE GOVT.
• Allotment of projects done haphazardly
• After getting upfront payment no real support from state
Govt.
Project developers are expected to provide many basic
amenities such as schools as CSR
• Next benefit to state accrues only after commercial
operation starts and free power is received
• There may be more than a couple of elections in between
• This, in spite of the huge long-term benefit to the State
Copyright © 2010 Jindal Steel & Power Ltd.
- 17. WHAT STATES COULD DO
• Be more proactive in matters of clearances
• Be a more proactive interface between project developers
and people
• Follow a basin-wise approach
• Invest in road and evacuation infrastructure planning and
development
• Backload tax burden
Copyright © 2010 Jindal Steel & Power Ltd.
- 18. POSITIVE DEVELOPMENTS
• Point of connection transmission
• 1% extra ROE proposed for reservoir schemes and pumped
storage schemes (however, needs to be extended to RoR
schemes too)
• Discussion has started on encouraging peaking power
through tariff: Committee under Chairmanship of CEA
Chairman
• Time of Day tariff introduced in some States
• These two measures will give hydro its due
