11.1 POWER DEVELOPMENT

The Power sector is faced with a number of challenges and problems. In order to overcome the poor financial stability, to off-set power shortage in the State, particularly during peak hours and to eliminate poor reliability and to maintain quality of power, the Government of Tamil Nadu took series of policy measures and implemented effective power sector reform in the State. The power sector reforms/strategies were formulated under the guidance/ policy framework put forwarded by the Ministry Power, Government of India which aimed at the following well defined objectives, namely - (i) sustained power supply to economic growth and development in the State, (ii) production of power at optimum cost, (iii) to supply reliable / quality power supply, (iv) appropriate financial stability to Tamil Nadu Electricity Board and (v) to find out suitable partnership for installation of new Independent Power Projects (I.P.Ps.) in the State. During Ninth Plan period, the State Government had mainly attributed to the following twin objectives, viz., - (1) Electricity must be supplied under the most efficient condition in the State in terms of quality/ cost in order to support economic development and (2) the power sector should be self-supporting and there should be a net generation of financial resources for the State. To achieve the above objectives, efforts were made to increase the Plant Load Factor (P.L.F.) of Thermal Stations in the State with the object of raising the Revenue component of the State Government and thereby increase the financial status of the Tamil Nadu Electricity Board (TNEB). High priority was given for Renovation and Modernisation of power plants. Measures were also taken to reduce T & D losses by providing adequate outlay/support to power sector / TNEB apart from Research and Development techniques in the State. The financial achievement registered at the end of the Ninth Plan period was 75.82 per cent.

Tenth Plan Period - Approach and Strategies for Power Development

Since Tamil Nadu State had exhausted most of its viable Hydel Power potential for power development at the beginning of the Sixth Plan itself, the State had left with no option but to go in for large scale Thermal/ Nuclear Power in order to meet/cope up with the demand/supply of power required during the subsequent Plan Periods. The share from Central Sector Projects like,- Madras Atomioc Power Station(MAPS), Kaiga Atomic Power Station(KAPS), Super Power Thermal Station (SPTS) at Ramagundam etc., have played a supportive/vital role besides I.P.Ps and Non-conventional sources of Energy in the State. Based upon the past experience and setbacks that was experienced, the approach and strategies for the Tenth Plan was formulated.

The main objectives of the Power Development Sector during Tenth Plan

are as furnished below:

• To bring Energy Security in the State by completing all the ongoing projects and the schemes, which could not be commissioned during previous, plan periods.

• To achieve 100 per cent electrification of households both in urban and rural areas.

• To select suitable circles to implement the improvement of sub-transmission schemes under Accelerated Power and Reforms Development Programme.

• To formulate long-range master plan to bring down the line losses from the present level of 16.5 per cent to 12 per cent.

• To create necessary policy and regulatory measures through TNERC.

• To focus/ concentrate on Energy Accounting and Auditing/ Demand Side Management and

• To increase the Plant Load Factor of Thermal Power and Hydel Power Stations in the State by undertaking Renovation and Modernisation Programmes and through R & D projects.

A Memorandum of Understanding (MoU) was signed on 9th January 2002 with

the Ministry of Power (MoP), Government of India by the Government of Tamil Nadu in order to bring Energy Security in the State. Following the agreement, a series of policy measures have been taken up to improve the functioning /financial condition of the TNEB apart from implementing the reform measures in the State pointed out by the Ministry of Power, Government of India. In recognition of Tamil Nadu being a Reforming State, the Power Finance Corporation (PFC), Rural Electrification Corporation (REC) etc., have been extending financial assistance/investment needs to TNEB in relaxation to normal conditionalities relating to the following factors viz.,- exposure limit, Rate of Returns (ROR), DSCR on development, reduce T & D losses, control of theft, 100 percent metering, restructuring of tariff rates etc. As per the guideline of Ministry of Power, Government of India, the private entrepreneurs are also permitted to install Independent Power Projects (I.P.Ps.) in the State in order to create/generate additional capacity to meet the ever-growing demand in the State in the following categories viz.,-Industry, Agriculture, Commercial, Domestic, Rural Electrification etc.

Physical Achievement made by the Tamil Nadu Eletricity Board

The TNEB occupies third rank in the list of top three SEBs in the country, along with Maharashtra and Gujarat, in terms of the size of its operation gauged by the generating capacity at its command/ the amount of energy sold/ and the number of consumers serviced. Tamil Nadu ranks sixth in terms of per capita electricity consumption among the other States. The technical performance/efficiencies of TNEB measured by the plant load factor and the transmission and distribution losses have normally been above the All-India average and among the top five to six SEBs. TNEB has been in the forefront of rural electrification too. Extending electricity to rural and promoting electrification of agricultural pumps have also been accorded top most priority in the TNEB's agenda. As early as 1992, TNEB had reached electricity to all the inhabited villages in Tamil Nadu and the number of electrified agricultural pump sets in the State has registered a phenomenal growth. The Power position/Number of consumers/Number of units consumed by various categories in Tamil Nadu State may be seen in the following graphical presentation.

Physical Targets/programmes of Power Sector in Tamil Nadu State

* TNEB has been programmed to create an additional capacity of about 30% by March 2007, i.e., 2631 MW (436 MW from State sector projects, 406 MW from Private sector projects, 1289 MW as share from Central sector projects and 500 MW from Joint sector) during the Tenth Plan period (2002-2007).

* Two mega projects have been proposed by Government of Tamilnadu to

the National Thermal Power Corporation (NTPC) and the Neyveli Lignite Corporation (NLC) which are likely to take off in the XI Plan period (2007- '12). In July 2002, the Tamil Nadu Electricity Board (TNEB) signed a Memorandum of Understanding with the NTPC for a 1000- MW plant at Ennore and a year ago, another with the NLC for a similar capacity plant at Tuticorin. The capacity of Tuticorin Plant has been fixed at 1000 MW now.

* The daily average Grid consumption during April to March 2003-04 was

135.133 MU as against 127.093 MU during the same period in 2002-03. The maximum daily consumption reached during April-March 2003-04 was 146.973 MU as on 31.03.2004 as against 139.778 MU as on 21.02.2003 during the same period last year. The maximum instantaneous Peak Demand reached on 16.03.2004 was 7247 MW as against 6960 MW on 21.02.2003.

The Plant Load Factor (PLF) is an important metric of the operational

efficiency of thermal power plants. The Plant load factor of TNEB's Thermal Stations for the period from April 2003- March 2004 vis-a-vis previous year is as follows:

Source:TNEB * The Thermal power stations of TNEB continued to perform well.

Hence,the State Government proposes to facilitate establishment of new power generation projects in order to meet the growing energy demand.

* In Transmission also, there has been a phenomenal expansion of the

network. From just 56 substations during pre-plan period (31.3.'51), the number has increased to 984 at the end of 2002-03 and transmission lines (ckt. kms.) from 1,819 to 16,474 during the same period. The Distribution network has also been expanded enormously, that is, from 5,117 HT ckt. kms., and 5,728 LT ckt. kms., in Pre-plan period (31.3.'51) to 1,23,588 HT ckt. kms & 4,56,633 HT ckt. kms respectively by the end of 2002-03. The number of Distribution Transformers has gone up from 1,591 to 1,48,752. By end of 2002-03, 26,764 AD colonies had been electrified, 13,11,173 huts electrified and 16,76,113 agricultural pumpsets energised. Further, concerted effort is being made to reduce T & D losses, reduce outages and interruptions and loss of power due to theft etc., and for upgradation and modernisation of sub-transmission and distribution segments.

* The ultimate aim of the TNEB is to bring down the line losses from the

present level of over 16% to 12% by a series of policy measures apart from the R&D activities for reactive power compensation, improvements in the designs of T&D factors, energy conservation/savings measures etc.

* The Tamil Nadu Electricity Board has also posed improvement schemes to

Rural Electrification Corporation and PFC for sanction towards reducing T & D losses over a period of five years. The TNEB has proposed to implement the above plan in a phased manner by availing loan assistance from APDRP, NABARD, REC and PFC in the State. At present, the T & D losses in Tamil Nadu are estimated at 16.25%.

* At present, there are 169.10 lakhs of service connections (as on

31.12.2004) .1069 substations , 1.46 lakh Kms of EHT/HT lines, 4.75 lakhs of Low Tension (LT) lines and 1.59 lakhs of Distribution Transformers available in the State.

Annual Plan 2005-2006

For Generation schemes, ‘no outlay’ has been provided in the Plan-Budget Link for the year 2005-2006. However, the TNEB continue to implement/incur expenditure on generation schemes/projects out of its own revenue resources apart from subsidy in the form of tariff compensation/loans/assistance/grants etc., by the State/Central Government support/and Other Agencies.
