Gross budgetary Support (GBS) and Plan Outlay (Rs. Crs.)

1.3 Investment Step up

In view of the various geological risks and engineering difficulties that are encountered in the developmentof hydroelectric power projects, private sector development has been slow in spite of good enthusiasm andincentives. Consequently, hydro power development has been taken up primarily through the public sector

in the 10

th

& 11

th

Plans. The Central public sector outlay for hydro power development has been enhancedfrom Rs. 12,306 Crs. to Rs. 25,839 Crs. and Budgetary support from Rs. 9,284 Crs. to Rs. 17,511 Crs.during the 10th Plan as compared to that in the 9th Plan.

2.0 Hydro Development

2.1 Initiatives taken by the Government for Hydro Power Development

To encourage greater participation by Indian and foreign entrepreneurs in hydroelectric power generation, anumber of measures have been taken by the Government for increasing the hydro capacity :

a) Policy Liberalisation

To accelerate capacity addition in the Power Sector, a policy to encourage greater participation by privateentrepreneurs in India and abroad in electric power generation has been announced. The Government hasissued notifications for hydro projects incorporating several incentives to private developers which broadlycover incentives for better availability of machines, for generation of extra energy above design energy,compensation for hydrological risks, etc.

i) Policy on Hydro Power Development

A Hydro Policy was announced in Aug.1998 for the development of hydro power incorporating severalenabling steps and measures. The Hydro Policy among other things lays emphasis on basin wise development,evolving consensus on inter-state issues, mitigation of geological risks, simplified procedure for transfer ofclearances, promoting joint venture arrangements etc. Main features of the policy are as under:

Additional budgetary support for ongoing and new Hydro Projects under Central PSUs.

Creation of Power Development Fund by levying cess on electricity generated in the country.

Basin-wise Development of hydro Potential.

Advance action for Capacity Addition in the 10thPlan & beyond.

Emphasis on Survey & Investigations.

Resolution of Inter-State issues.

Renovation, Modernisation & Uprating of existing hydro stations.

Promoting Small & Mini Hydel Projects.

Simplified Procedures for Transfer of Clearances by CEA.

Rationalisation of Hydro Tariff by allowing premium on sale rate during peak period.

Realistic estimates of completion cost considering geological surprises.

Promoting Hydel Projects with Joint Ventures.

Selection of Developer through MOU/Bidding route.

Govt. Support for Land Acquisition, Resettlement and Rehabilitation, Catchment Area Development etc.

Some of the measures announced by Govt. of India have already been introduced which include SimplifiedProcedures for transfer of Techno-Economic Clearances, Streamlining of Clearance process and introduction ofThree-Stage Clearance approach for development of hydro Projects in Central Sector/ Joint Ventures etc.

The CERC has approved 5% hydro development surcharge on annual fixed charges for central hydro power

generation.

ii) Three Stage Clearance Procedure

The Government has also approved a Three Stage Clearance procedure for hydro projects to be executed bythe CPSUs in consultation with the Ministries of Finance and Environment and Forests. Under Stage-I, theCPSUs will incur expenditure on survey, investigation and preparation of a pre-feasibility report. Under

Stage-II, the CPSUs will undertake activities relating to detailed investigation and preparation of Detailed ProjectReport. During this Stage, pre-construction activities and infrastructure development including land acquisition willalso be undertaken. Under Stage-III, investment sanction will be accorded through the PIB/ CCEA.

iii) The investment policy has been made more attractive from time to time and provides for (i) Debt:Equity ratioup to 4:1 (ii) 100% foreign equity participation (iii) liberalized rates of depreciation in respect of assets (iv)import of equipment for power projects at concessional customs duty (v) 16% rate of return on equity (vi)Generating companies can sell power on the basis of a suitably structured two part tariff - one part to coverfixed costs and the other to cover variable costs at a prescribed level of performance.

iv) Since hydroelectric projects have lower internal rate of return compared to the thermal and gas based

projects, the Government has notified new norms for incentives where the availability factor threshold hasbeen reduced from 90% to 85%. Similarly, the sale rate of secondary energy has been notified at the samerate as primary energy.

v) The procedures relating to transfer of clearances from State Government to Central Public Sector Undertakingsand State Government to Private Sector have been simplified. Under the revised guidelines, clearance isautomatically transferred to the new agency if the scope of work has not changed and CEA only examinesthe revised cost and financial package of the new proposal before transferring the clearance.

vi) Ceiling limits of capital costs upto which techno-economic clearance of CEA is not required has beenenhanced, inter-alia, for hydro projects. According to the present notification issued under Section 29 of theElectricity (Supply) Act, 1948, hydro projects are covered by the following limits :

Rs. 250 Crores for projects awarded through the MOU route.

Rs. 1,000 Crores for projects awarded through competitive bidding.

Rs. 2,500 Crores for projects whose tariff is determined by the CERC/ SERCs.

All hydro-electric projects utilizing water of inter-state rivers shall be submitted to CEA for its concurrence

(irrespective of capital cost).

b) Creation of Power Utilities in Central Sector

Government has taken many steps and measures to boost Hydro Power Development. Hydro power

corporations in the central sector and the joint sector (central and state) National Hydro-electric Power

Corporation (NHPC), North-Eastern Electric Power Corporation (NEEPCO), Nathpa-Jhakri Power Corporation

(NJPC) renamed as Satluj Jal Vidut Nigam Limited (SJVNL) and Tehri Hydro Development Corporation (THDC)

have been created. Besides, National Thermal Power Corporation Ltd. (NTPC) has also been authorised to

take up hydro projects (Kol Dam). Narmada Hydro Development Corporation (NHDC), a joint venture of

NHPC and MP Govt. has been constituted to implement Indirasagar (1000 MW) and Omkareshwar

(520 MW) HE projects.

2.2 First Hydroelectric Survey of India (1953-59)

The first systematic Hydro Electric Survey of India was undertaken by the erstwhile Central Water & Power

Commission (CW&PC) during1953-59. According to this survey, Hydro Electric Potential of the country was

assessed as about 42 Million kW from a total of about 250 schemes. The results of the first survey proved

useful in chartering the course of hydroelectric development of the country for about two decades.

2.3 Reassessment of Hydroelectric Potential (1978-87)

The Reassessment Studies (1978-87) of Hydro Electric Potential were undertaken by Central ElectricityAuthority (CEA) on the advice of Planning Commission which had expressed concern over the lack ofavailability of up to date data regarding hydro electric potential of the country.

Planning Commission had opined that in view of the spurt in fuel cost and technical advancements madein hydro project construction, some of the hydel schemes not considered economically attractive in the fifties

would have since become viable.

The countrys power system had experienced tremendous growth and regional grid networks increased theenergy utilization capability.

Very useful hydrological, meterological and other related data was also available consequent to large-scaledevelopment of water resources in the country during fifties & sixties.

The scope of the Reassessment Studies also included Assessment of Gross Theoretical Potential, SecondaryEnergy contribution and Identification of possible sites for Pumped Storage development in addition toassessment of economic potential and computation of annual energy contribution in dependable and average

flow conditions.

The Reassessment Study completed in 1987 revealed that the Hydro Electric Power Potential of thecountry was of the order of about 84 million kW from a total of 845 schemes as against 42 million kWfrom 250 schemes identified at the time of the first survey. 56 sites for development of Pumped StorageSchemes with total likely installed capacity of about 94,000 MW were also identified in various regions ofthe country.

2.4 Categorisation of Hydroelectric Potential: Ranking Studies

To give necessary fillip for development of the balance Hydroelectric schemes, CEA undertook RankingStudies to determine inter-se priority for their development. The objective of this exercise was to facilitateidentification of the projects for implementation in order of their priority so that hydro development couldbe taken up in appropriate sequence.

2.4.1 Projects Identified

With a view to prioritise the large number of identified schemes to harness vast untapped hydro resourcesin the order of their attractiveness for implementation, ranking studies were carried by CEA and 399schemes were prioritised under categories A, B & C. Category-A schemes were considered moreattractive than Category-B schemes and Category-B schemes being more attractive than Category-C schemes. The studies were carried out in consultation with Ministry of Environment & Forest, CentralWater Commission, Geological Survey of India, National Remote Sensing Agency, Survey of India etc. TheRanking Study gives inter-se prioritisation of the projects which could be considered for further implementationincluding their survey & investigation so that hydro power development is effected in an appropriate

sequence. The Ranking Study was completed in 2001-02.2.4.2 Process of Ranking Study

Ranking Study generally involved sophisticated desk studies of all secondary topographical and hydrologicaldata. For this purpose latest topo sheets were obtained from Survey of India. In addition, Satellite imagerieswere also obtained from NRSA for Indus Basin.

Ten major aspects pertaining to development of the identified projects, which play vital role in theimplementation of the hydro projects were adopted in the criteria considered for ranking study. For eachof the criteria, certain marks with weightage ranging from minimum of 6 to maximum of 15 were allotted.These aspects are R&R Aspects, International Aspects, Inter-state Aspects, Potential of the Scheme, Type ofScheme, Height of Dam, Length of Tunnel/Channel, Accessibility to Site, Status of the Project, Status of

3.0 Feasibility Studies

Based on the preliminary ranking study, the Preliminary Feasibility Reports (PFRs) of selected schemes arebeing prepared incorporating the general description of the schemes, essential drawings, engineering aspects,approximate estimated cost and economic evaluation.

3.1 Identification of Projects for PFRs

Projects Identification

Ranking study carried out by CEA covered 399 Hydro Electric Potential sites with total installed capacity ofabout 1,07,000 MW.

The results of the Ranking study were discussed at length in a consultation process initiated byMinistry of Power and CEA with various state agencies, CPSUs & other organizations. As a follow up ofthe ranking studies, it was considered appropriate that for development of balance hydro projects in a

systematic manner, shelf of viable projects needs to be made available so that the same could beoffered for development to prospective entrepreneurs in India and abroad. Two rounds of discussions wereheld in CEA to elicit the views of state authorities/ CPSUs regarding their programme and preparedness totake up hydro power development. Separate consultations were also held with states possessingvast untapped hydro electric potential namely Arunachal Pradesh, Uttaranchal, Himachal Pradesh and Jammu& Kashmir.

Based on deliberations during the above meetings, it was considered appropriate that Preliminary FeasibilityReports (PFRs) of selected hydro electric projects may be taken up so that feasibility of the scheme consideredin ranking studies could be established.

In the first instance, PFR formulation of 162 HE schemes has been taken up. Schemes, identified by StateAuthorities/CEA for which S&I are either in initial stages or are yet to be taken up have been consideredfor PFR formulation. Schemes for which DPRs have either been prepared or returned, are generally notincluded under the proposed studies. Schemes for which S&I is in advance stage and DPRs are likely to beformulated shortly, have also not been included in the proposed study. The schemes to be studied for PFRshave a likely installed capacity above 50 MW.

3.2 The Next Step

The Preliminary Feasibility Reports will provide information on hydroelectric schemes which are yet to bedeveloped and enable their prioritisation for further action for implementation. The PFRs would also provideuseful information to prospective developers for taking up detailed Survey & Investigation and DPR

formulation. Results of studies would thus facilitate development of balance hydro electric potential in thecountry in order of the viability/ attractiveness.

After completion of studies for PFRs, action for taking up detailed S&I and DPR preparation would be initiatedfor schemes considered viable. This is considered essential to generate a shelf of projects which could betaken up for execution during 11thand 12thPlans and beyond.
