POWER SECTOR-AN OVERVIEW

Electricity - Concurrent Subject: jointresponsibility of State and Central

Governments.

Bulk of transmission and distribution

functions with State Utilities.

Private sector - small presence inDistribution and making entry into

Transmission.


5/69

POWER SECTOR-AN OVERVIEW

Conventional Generation - blend of thermal, hydroand nuclear sources.

Coal based thermal power plants and in some regions

hydro power plants - mainstay of electricity generation.Oil, natural gas and nuclear power accounts for

smaller proportion of power.

Emphasis also on non-conventional energy sources

i.e. solar, wind, biogas and tidal. Captive power plants being encouraged to supply

surplus power to Grid.

Access to electricity for all households in next 5years.

Availability of power on demand to be fully met by2012

Energy shortage and peaking shortage to beovercome by providing adequate spinningreserves

Reliability and quality of power to be supplied in

efficient manner . Electricity Sector to achieve financial turnaround

and commercial viability

Consumersinterests to be accorded top priority.

NATIONAL ELECTRICITY POLICY THE WAY FORWARD


11/69

NATIONAL ELECTRICITY POLICY - ENCOURAGING PRIVATE

PARTICIPATION

Competition encouraged - to bring significant benefit toconsumers

Guidelines for competitive bidding issued by Government inJanuary,2005.

Role of private participation in generation, transmission anddistribution to become increasingly critical in view of rapidlygrowing investment needs.

Central and State Governments to develop workable andsuccessful models for public private partnership.

Special mechanisms to be created to encourage private investment

in transmission sector


12/69

NATIONAL ELECTRICITY POLICY - ENCOURAGING PRIVATE

PARTICIPATION

Private Sector participation in distribution encouraged forachieving requisite reduction in T&D losses and improvingquality of service to consumer

Multi Year tariff framework- important structural incentiveto minimize risks for utilities and consumers, promoteefficiency and rapid reduction of system losses.

Competition through concept of multiple licensees in same

area through their independent distribution system


13/69

Electricity Act & National Electricity Policy mandatesnon-discriminatory open access in transmission and, inphases in distribution.

Respective State Regulatory Commissions to

facilitative framework for open access. Well planned and strong transmission and distribution

system to ensure optimal utilization of transmissioncapacities

Would facilitate achieving objective of cost effectivedelivery of power.

Distribution reform - key to long term sustainability of

the power sector.
