BROAD TIMELINE Electricity(Supply) Act,1948 Major Challenges : Few Regulations: State sector Dominant. Two-part tariff introduced Lack of Inter-Regional Private Sector Participation- in 1992 Transmission Network. : licensed CERC was established Default in Payments by SEBs Constant Peak and energy deficit. ABT introduced in 2000 and lack of liquidity-Single Low growth for Central sector point tariff. End of IV End of IX 1950 Plan Plan (1973-74) (2001-02) All India IC 1713 MW Inadequate Resources led Central Sector IC Constitution of Central companies: 31605.5 MW (30%) Central NTPC, NHPC , NEEPCO , NPCIL. Sector IC Large Capacities(200/210 MW) Huge Demand 2507.5 MW Regional Projects-Regional grid. for CGS Power Rate of growth of Central sector outpaced State Sector .
Timeline: X – XII Plan (2002-2017) Electricity Act,2003. Huge investment planning: 61000 Delicensed Regime. MW PPAs signed by states with Promoted Competition, Open NTPC. Access. High Participation by Private Private Sector Participation sector - Attractive ROE. Better performance by Central sector plants. Regulations insulated Cent. X plan XI plan XII plan Generating Comp. from Losses Begin Begin Begin (2002-03) (2007-08) (2012-13) Regulations: Relevant Regulations: Tariff Regulation 2009-14(ROE=15.5 %). National Tariff Policy Surrender of firm allocation by a 2006-Competitive beneficiary as per tariff regulations Bidding. 2009. Multi YearTariff regulations 2004-09.
Current scenario Surrendering of firm power by states to the tune of 3890 MW . Highest ever capacity addition - private sector. Power Exchanges flourished. Power tariffs have reduced in open market. Demand of Power High Tariffs for non-pit head CGSs. from CGSs Surplus power for many states. XII Plan
