Tariff Petition 2008-09 to 2010-11 - WBSEDCL

TARIFF PETITION- 2008-09,2009-10 & 2010-11Annual generation at PPSP at a level of 800 MU during the year 2008-09, 2009-10and 2010-11 has been estimated according to the system requirement during peak hoursconsidering optimum utilization of the surplus energy mainly during off peak hours.3.1.3 Gas Turbine Stations :The gas turbine power station at Kasba ( 2X 20 MW) , Haldia (2 X 20MW) andSiliguri ( 1X 20 MW) built up in late seventies during the period of severe power crisiswere operated primarily during the peak hours and also beyond peak hours under severepower shortage conditions at that time. Consequent upon improvement in power positionin mid-eighties, the gas turbine stations were only operated during emergency. Sincethese power stations were not utilised on regular basis no major investment was made tokeep these power station in running condition. Hence due to normal wear and tear of theequipment these power stations are now lying in defunct condition.As such, no generation from these power stations as well as no cost for those Stationshas been considered for the ensuing years.3.1.4 Diesel Stations :At present the Board is maintaining diesel generation plant only at Rudranagar inSagar Island. In view of excessive cost associated with diesel generation, generationfrom diesel generating plants had to be restricted and the same has been supplementedby other source of power i.e. from non-conventional energy sources. The load inRudranagar in Sagar Island is now being catered partly through Diesel generation andpartly from Non-conventional energy sources (Solar Power). The level of dieselgeneration at lone Power Station at Rudranagar is low. In absence of adequate capacityaddition from non-conventional sources and to meet the increased load demand duringprevious years a new desesel set of capacity of 320 KVA has been commissioned in2007-08. Energy to be available from this diesel based generating stations has beenestimated at 1.04 MU, 1.14 MU and 1.26 MU in FY09, FY10 and FY11 respectively.3.1.5 Green Power :Like previous years, Hon’ble Commission in the Tariff Order for 2007-08 kindlydirected WBSEDCL to explore the possibilities of purchase of power from renewable andWest Bengal State Electricity Distribution Company Ltd. 27
