1.0 Power Sector Development in India Harnessed energy has become a symbol of growth and instrument for development. Electric power particularly the hydro is among the cleanest end use energy inputs for economic activity, domestic and civic conveniences, climate control, communication and technology. The Ministry of Power has set an objective of providing “Power for all by 2012”. This will entail electrification of all villages by 2007 and of all households by 2012. The infrastructure would need the availability of assured and quality power at affordable price through reliable and adequate generation, transmission and distribution facilities. Power generation in India began more than a century ago in 1898 when the first hydro power unit was set up at Darjeeling. When India attained freedom in 1947, the country had an installed capacity of 1,360 MW. The present installed generating capacity in the country is 1,07,973 MW. The share of hydro with 26,910 MW capacity is about 25%. Thermal accounts for maximum share of 71% with 76,607 MW. It comprises of 63,801 MW from Coal, 11,633 MW from Gas and 1,173 MW from Diesel. The share of Nuclear is about 2.5% with 2,720 MW while Wind accounts for the balance 1,736 MW. The attainment is significant. However what we achieved in over 50 years will need to be attained now in nearly 10 years.

Shares in Installed Capacity - March, 2003 The present annual energy requirement in 2002-03 was 5,45,674 MU, of which only 4,97,589 MU were available, leaving a shortfall of 8.8%. While the peaking requirement was 81,492 MW in 2002-03, a peak of 71,547 MW only could be met, leaving a shortage of 12.2%. The 16th Electric Power Survey (EPS) carried out by the Central Electricity Authority has projected a peak demand of 1,15,705 MW and an energy requirement of 7,19,097 MU by the end of 10th Plan while the requirement by the end of 11th Plan has been projected as 9,75,222 MU and 1,57,107 MW respectively. Accordingly at the end of the 10th Plan, an additional capacity of 55,158 MW is needed. However it is likely that a capacity addition of 41,110 MW would only be feasible during the period keeping in view the financial level of the power sector and preparedness of projects. The effort is to close the deficit by the end of the 11th Plan to ensure “Power for all by 2012”. The Indian power system requirement had been assessed to need a hydro power and thermal/nuclear power mix in the ratio of 40:60 for flexibility in system operation depending on typical load pattern. The present ratio is 25:75 which needs to be corrected immediately to meet peak load requirements as well as system and frequency stability. 2

The estimated hydro potential in the country is 1,50,000 MW (corresponding to 84,044 MW at 60% load factor) out of which only 26,910 MW amounting to 18% of the total potential has been harnessed. While 14,393 MW hydro capacity is planned to be added in 10th Plan, action has been taken to ensure that more than 20,000 MW of hydro capacity is added during the 11th Plan period.

Global Scenario

1.1

Advantages of Hydro Power Hydro power is a renewable, economic, non polluting and environmentally benign source of energy. Hydro power stations have the inherent ability for instantaneous starting, stopping, load variations etc. and help in improving reliability of power system. There is no fuel cost during the life of the station as hydro power generation is a non consumptive use of water. The benefits of hydro power as a clean, environment friendly and economically attractive source of energy have now been sufficiently recognised. The need for its accelerated development also comes from its capability of enhanced system reliability and economics of utilization of resources.

1.2

Need for Hydro Share Correction

At the time of Independence, the share of hydro in the total installed capacity was around 37% which continued to rise, crossing 50% in the year 1963. The share of hydro, however, started declining thereafter. Until the late seventies, the share of hydro remained above 40%, considered to be the ideal hydro-thermal mix for meeting the demand in an efficient manner. However, ever since the eighties, the share of hydro has started declining sharply and at present, the share of hydro constitutes only about 25% of the overall installed capacity of the country. 3

1.3

Investment Step up In view of the various geological risks and engineering difficulties that are encountered in the development of hydroelectric power projects, private sector development has been slow in spite of good enthusiasm and incentives. Consequently, hydro power development has been taken up primarily through the public sector in the 10th & 11th Plans. The Central public sector outlay for hydro power development has been enhanced from 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.

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

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, a number 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 private entrepreneurs in India and abroad in electric power generation has been announced. The Government has issued notifications for hydro projects incorporating several incentives to private developers which broadly cover 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 several enabling 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 of clearances, 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 10th Plan & 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 Simplified Procedures for transfer of Techno-Economic Clearances, Streamlining of Clearance process and introduction of Three-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. 5

ii)

Three Stage Clearance Procedure

The Government has also approved a Three Stage Clearance procedure for hydro projects to be executed by the CPSUs in consultation with the Ministries of Finance and Environment and Forests. Under Stage-I, the CPSUs 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 Project Report. During this Stage, pre-construction activities and infrastructure development including land acquisition will also 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 ratio up 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 cover fixed 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 has been reduced from 90% to 85%. Similarly, the sale rate of secondary energy has been notified at the same rate as primary energy.

v)

The procedures relating to transfer of clearances from State Government to Central Public Sector Undertakings and State Government to Private Sector have been simplified. Under the revised guidelines, clearance is automatically transferred to the new agency if the scope of work has not changed and CEA only examines the 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 been enhanced, inter-alia, for hydro projects. According to the present notification issued under Section 29 of the Electricity (Supply) Act, 1948, hydro projects are covered by the following limits : y Rs. 250 Crores for projects awarded through the MOU route. yRs. 1,000 Crores for projects awarded through competitive bidding. y 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 Electricity Authority (CEA) on the advice of Planning Commission which had expressed concern over the lack of availability 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 made in hydro project construction, some of the hydel schemes not considered economically attractive in the fifties would have since become viable. · The country’s power system had experienced tremendous growth and regional grid networks increased the energy utilization capability. · Very useful hydrological, meterological and other related data was also available consequent to large-scale development of water resources in the country during fifties & sixties.

The scope of the Reassessment Studies also included Assessment of Gross Theoretical Potential, Secondary Energy contribution and Identification of possible sites for Pumped Storage development in addition to assessment 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 the country was of the order of about 84 million kW from a total of 845 schemes as against 42 million kW from 250 schemes identified at the time of the first survey. 56 sites for development of Pumped Storage Schemes with total likely installed capacity of about 94,000 MW were also identified in various regions of the country.

Categorisation of Hydroelectric Potential: Ranking Studies

To give necessary fillip for development of the balance Hydroelectric schemes, CEA undertook Ranking Studies to determine inter-se priority for their development. The objective of this exercise was to facilitate identification of the projects for implementation in order of their priority so that hydro development could be 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 resources in the order of their attractiveness for implementation, ranking studies were carried by CEA and 399 schemes were prioritised under categories A, B & C. Category-’A’ schemes were considered more attractive 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, Central Water Commission, Geological Survey of India, National Remote Sensing Agency, Survey of India etc. The Ranking Study gives inter-se prioritisation of the projects which could be considered for further implementation including 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 hydrological data. For this purpose latest topo sheets were obtained from Survey of India. In addition, Satellite imageries were also obtained from NRSA for Indus Basin. Ten major aspects pertaining to development of the identified projects, which play vital role in the implementation of the hydro projects were adopted in the criteria considered for ranking study. For each of 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 of Scheme, Height of Dam, Length of Tunnel/Channel, Accessibility to Site, Status of the Project, Status of 8

Upstream or Downstream Hydel Development. These criteria were discussed in detail at a Consultation Forum involving various organisations from different spheres involving technical/ commercial/ financial institutions/ confederations/ associations/ utilities/ experts and bodies. On the basis of the Marks obtained, schemes were ranked into A, B and C categories as below: Category

3.0 Feasibility Studies Based on the preliminary ranking study, the Preliminary Feasibility Reports (PFRs) of selected schemes are being 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 of about 1,07,000 MW. The results of the Ranking study were discussed at length in a consultation process initiated by Ministry of Power and CEA with various state agencies, CPSUs & other organizations. As a follow up of the 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 be offered for development to prospective entrepreneurs in India and abroad. Two rounds of discussions were held in CEA to elicit the views of state authorities/ CPSUs regarding their programme and preparedness to take up hydro power development. Separate consultations were also held with states possessing vast 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 Feasibility Reports (PFRs) of selected hydro electric projects may be taken up so that feasibility of the scheme considered in ranking studies could be established. In the first instance, PFR formulation of 162 HE schemes has been taken up. Schemes, identified by State Authorities/CEA for which S&I are either in initial stages or are yet to be taken up have been considered for PFR formulation. Schemes for which DPRs have either been prepared or returned, are generally not included under the proposed studies. Schemes for which S&I is in advance stage and DPRs are likely to be formulated shortly, have also not been included in the proposed study. The schemes to be studied for PFRs have 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 be developed and enable their prioritisation for further action for implementation. The PFRs would also provide useful 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 the country in order of the viability/ attractiveness. After completion of studies for PFRs, action for taking up detailed S&I and DPR preparation would be initiated for schemes considered viable. This is considered essential to generate a shelf of projects which could be taken up for execution during 11th and 12th Plans and beyond. 3.3
