Second pole test charged on Besides Talcher-II power it would facilitate transfer of surplus power of Eastern Region to Southern Region

EVOLUTION OF POWER SYSTEM IN INDIA
PRE INDEPENDENCE - SMALL ISOLATED SYSTEM PRIOR TO 60s - GENEARTION/TRANSMISION BY SEBS DURING 60s - LIMITED INTERCONNECTION BETWEEN NEIGHBOURING STATES 70s - EMERGENCE OF CENTRAL SECTOR GENERATION ( NTPC/NHPC/NUCLEAR ETC.) PLANNING OF GENERATION/TRANSMISSION ON REGIONAL BASIS LATE 80s – INTEGRATED GRID OPERATION THRO’ 400kV SYSTEM LATE 90s - ASYNCHRONOUS INTER REGIONAL LINKS LONG DISTANCE HVDC LINKS / BtB STATIONS

POST INDEPENDENT INDIA
ELECTRICITY AN INDEX FOR DEVELOPMENT OF THE NATIONAL ECONOMY. INVOLVEMENT OF STATE GOVERNMENTS FOR DEVELOPMENT OF THE POWER SECTOR. CENTRALISED CONTROL FOR COORDINATION AND IMPLEMENTATION BY STATE OR REGIONAL BODIES

Power sector is governed by three principal Acts namely –
i) The Indian Electricity Act, 1910, deals with functioning and regulation of the private licensees ii) The Electricity (Supply) Act, 1948 deals with establishment and functioning of SEBs iii) The Electricity Regulatory Commissions Act, 1998. establishment of SERCs & CERC

INDIAN ELECTRICITY ACT 1910
(ACT 9 OF 1910) INTRODUCE THE CONCEPT OF LICENCES IMPOSE CERTAIN DUTIES AND LIABILITIES ON SUCH LICENSEES. INTRODUCE CERTAIN PENAL PROVISIONS

IMPORTANT PROVISIONS OF ELECTRICITY (SUPPLY) ACT 1948
FORMATION OF CEA FORMATION OF SEBs GREATER RESTRICTION AND CONTROL ON THE LICENSEES’ OPERATION LAYING DOWN PRINCIPLES OF TARIFF SPELLING OUT FINANCIAL PRINCIPLES AND THEIR APPLICATION BOTH FOR THE SEBs AND LICENSEE

AMENDMENT OF 1998 DEFINES CENTRAL TRANMISSION UITILITY
DEFINES CENTRAL TRANMISSION UITILITY INTER-STATE TRANSMISSION OF POWER STATE TRANSMISSION UTILITY TRANSMISSION LICENSEES.

ELECTRICITY ACT AMENDMENTS IN 1998 SALIENT FEATURES
TRANSMISSION RECOGNISED AS SEPARATE ACTIVITY AND CONCEPT OF TRANSMISSION LICENSEE REDUCED CONCEPT OF A CENTRAL TRANSMISSION UTILITY (CTU) AND STATE TRANSMISSION UTILITIES (STUs) RLDCs TO BE OPERATED BY POWERGRID UNLESS OTHERWISE SPECIFIED BY THE GOVERNMENT RLDCs DESIGNATED AS APEX BODIES TO ENSURE INTEGRATED OPERATION OF POWER SYSTEM IN EACH REGION RLDCs TO ENFORCE ABOVE DECISIONS OF REBs

ELECTRICITY REGULATORY COMMISSION ACT 1998
THIS ACT PROVIDES ESTABLISHMENT OF CENTRAL ELECTRICITY REGULATORY COMMISSION ESTABLISHMENT OF STATE ELECTRICITY REGULATORY COMMISSION , RATIONALIZATION OF ELECTRICITY TARIFF,

Regional Load Despatch Centres (RLDCs)
NEED FOR A CONTROL CENTRE (RLDC) IN EACH REGION FELT IN LATE SEVENTIES RLDCs UNDER CEA / REB.

The installed capacity
1362 MW in 1947 93249 MW in March 1999

Indian Power Scenario Current capacity - 115 GW
50 times increase in last 50 years since Independence

Forms of Power

Growth Plans Annual growth in last 4 years - 3000 MW
Optimistic scenario to 6000 MW per year in the next 4 to 5 years. Pessimistic Scenario MW p.a. 1/3 to ¼ of from IPPs. Rest from SEBs / NTPC / NHPC etc
