TARIFF PETITION- 2008-09,2009-10 & 2010-11generated from the said plant is under process. Considering the present status of work,of the said plant and the other plants to come up with co-generation and non–conventional sources, annual generation from those proposed plant ( other green power)has been estimated at 75 MU during the years 2008-09, 2009-10 and 2010-113.2. Cost of Power Purchase :3.2.1. On implementation of West Bengal Power Sector Reform Transfer Scheme 2007WBSEDCL becomes the Distribution Licensee as a successor entity of WBSEB.Accordingly WBSEDCL is continuing to purchase power in the same manner as wasfollowed by erstwhile WBSEB from different power supply agencies namely West BengalPower Development Corporation Ltd (WBPDCL), the Durgapur Projects Limited (DPL),Dishergarh Power Supply Company Limited (DPSC), the Damodar Valley Corporation(DVC), National Thermal Power Corporation Limited (NTPC), National Hydro PowerCorporation (NHPC), the Power Trading Corporation (PTC). On commissioning of TalaHydro Electric Power in Bhuttan since August’ 2006, MOP Govt. of India has allocatedpower from Tala HEP to the State of West Bengal with equivalent curtailment of sharefrom ISGS Power Stations of NTPC in Eastern Region. This power from TALA HEP isbeing imported for different States in India by PTC.3.2.2. WBSEDCL will also purchase green power from the West Bengal RenewableEnergy Development Agency (WBREDA) and from other non-conventional sources ofenergy developed by private entrepreneurs during the ensuing years 2008-09, 2009-10and 2010-11. The planning of power purchase is done by WBSEDCL keeping in view thefollowing aspects:• Estimated system demand for the ensuing years based on the projectedload growth.• Maximum generation that may be available from the Hydel Power Stationsof WBSEDCL• Commitment to meet the peak system demand.• Optimisation of power purchase cost with an eye on merit order purchaseas far as practicable.West Bengal State Electricity Distribution Company Ltd. 29
TARIFF PETITION- 2008-09,2009-10 & 2010-11• Reduction in purchase of energy from DVC, DPL and DPSCL in radialmode by way of taking over the loads in steps.• Requirement of pumping energy for optimum utilisation of PPSP to meetthe peak system demand.WBSEDCL is trying to follow the principles for purchase of power on merit orderbasis as directed by the Hon’ble Commission but there are certain practical constraints instrictly following the same. Though WBSEDCL has taken initiative to take over the loadof Asansol area which are now being supplied radially from DPSC and DVC substationsin staggered manner, still it will continue the existing arrangement of purchase of somequantum of power in radial mode from DVC (at 33 KV), DPL (at 33 KV & 11 KV) -around Durgapur area and DPSC (at 11 KV) at Asansol area for catering its ownconsumers irrespective of the tariff of these agencies during the ensuing years. Butthese loads are being taken over in stages by way of developing infrastructure. Secondly,the entire generation (sent out) of the WBPDCL and surplus power of DPL at 132 KVinterconnecting mode is to be accommodated by the WBSEDCL through purchase.Thirdly, the WBSEDCL has to import power from Central Sector Power Stations e.g.NTPC, NHPC Ltd up to the complete level of allocated share in order to reduce theburden of fixed charge, which otherwise would have to be shouldered by theWBSEDCL’s consumers due to increase in per unit purchase cost for drawing lesserquantum of power. In the above context it is also a fact that after meeting therequirement of consumer, other licensees of the state and requirement of pumpingenergy of PPSP there will be some incidental surplus energy. This incidental surplusenergy available in the WBSEDCL system mainly during off-peak hours will be sold toothers on long term basis resulting in reduction of overall revenue requirement ofWBSEDCL. While releasing the radial loads from DVC, WBSEDCL will take up with DVCfor supplying some quantum of power through grid. It may, therefore, be appreciated thatthe WBSEDCL has very little room to strictly follow merit order power purchase plan.West Bengal State Electricity Distribution Company Ltd. 30
