Petition for approval of capital schemes FY 2011-12/12-132. INTRODUCTION<strong>Chhattisgarh</strong> <strong>State</strong> <strong>Power</strong> <strong>Generation</strong> <strong>Company</strong> <strong>Limited</strong> (CSPGCL), a successor company of<strong>Chhattisgarh</strong> <strong>State</strong> Electricity Board (CSEB) is for undertak<strong>in</strong>g the „generation function‟ of CSEBfrom 01.01.2009 <strong>in</strong> accordance with Transfer Scheme notified by <strong>State</strong> Government.CSPGCL is supply<strong>in</strong>g 100% of power generated by its power stations to <strong>Chhattisgarh</strong> <strong>Power</strong>Distribution <strong>Company</strong> <strong>Limited</strong> (CSPDCL) at the tariff decided by <strong>Chhattisgarh</strong> <strong>State</strong> ElectricityRegulatory Commission (CSERC). <strong>Chhattisgarh</strong> <strong>State</strong> Electricity Board (CSEB) was a part ofthe erstwhile Madhya Pradesh Electricity Board (MPEB) till 2000. It became a separate entity onthe formation of the <strong>State</strong> of <strong>Chhattisgarh</strong>. The board functioned as an <strong>in</strong>tegrated entity tillDecember 2008 when the <strong>State</strong> Government notified a transfer scheme for unbundl<strong>in</strong>g it. Thetransfer scheme resulted <strong>in</strong> the formation of five successor entities for undertak<strong>in</strong>g the functionsof the erstwhile board. <strong>Chhattisgarh</strong> <strong>State</strong> <strong>Power</strong> <strong>Generation</strong> <strong>Company</strong> <strong>Limited</strong> (CSPGCL) isone of the five successor entities, formed for undertak<strong>in</strong>g the „generation function‟ of CSEB.CSPGCL started operations on 1 st January 2009.CSPGCL’s <strong>Generation</strong> PortfolioApproximately 98% of CSPGCL‟s generation capacity (1900 MW) is located <strong>in</strong> Korba. Details ofCSPGCL‟s plants have been provided <strong>in</strong> the follow<strong>in</strong>g table.Details of Installed capacity for CSPGCL as on 1 st April 2011NO. NAME OF PLANT YR OF COMM.

It issubmitted that despite their age, the plants have performed well, meet<strong>in</strong>g most operationalbenchmarks set by <strong>Chhattisgarh</strong> <strong>State</strong> Electricity Regulatory Commission, however, at thesame time it may be appreciated that the old plants need fair degree of capital <strong>in</strong>vestment toma<strong>in</strong>ta<strong>in</strong> their operational worth<strong>in</strong>ess and to take care of statutory and safety requirements.Page 4 of 46


Petition for approval of capital schemes FY 2011-12/12-13Bus<strong>in</strong>ess PlanThe Bus<strong>in</strong>ess plan <strong>in</strong> compliance of the provisions of <strong>Chhattisgarh</strong> <strong>State</strong> Electricity RegulatoryCommission‟s (Terms & conditions of determ<strong>in</strong>ation of tariff accord<strong>in</strong>g to Multi-year tariffPr<strong>in</strong>ciples) Regulations, 2010 for the control period FY 2010-11 to 2012-13 was submitted <strong>in</strong>March 2010. Hon‟ble Commission passed its order on the same <strong>in</strong> June 2010. The petition andthe order, encompassed issues related to New projects, Renovation & Modernisation schemesand capital O&M and civil schemes.Hon‟ble Commission has desired that capital O&M and capital civil projections shall besubmitted plant wise and scheme wise. CSPGCL, on its part craved leave for such submissionon year to year basis as ascerta<strong>in</strong>ment of such needs <strong>in</strong> 2/3 year advance has got practicallimitations. Consider<strong>in</strong>g the issue, Hon‟ble Commission ordered as under :“2.56 Further, CSPGCL has stated that it is not possible to forecast such schemes forFY 2011-12 and FY 2012-13 <strong>in</strong> advance. Therefore, the Commission is not <strong>in</strong>cl<strong>in</strong>ed toapprove the <strong>in</strong>vestment <strong>in</strong> advance amount<strong>in</strong>g to Rs. 113.06 Cr and Rs. 119.52 Crenvisaged for FY 2011-2012 and FY 2012-2013 respectively. CSPGCL mayseparately submit scheme wise details for approval of the Commission under capitalO&M and capital civil for FY 2011-12 and FY 2012-13.”Further, while approv<strong>in</strong>g the schemes for 2010-11, Hon‟ble Commission disallowed anyprovision for cont<strong>in</strong>gencies and <strong>in</strong>stead provided:“ 2.57. The Commission has also disallowed the cont<strong>in</strong>gency provision of Rs 10 Crproposed for unforeseen capital nature work and is of the view that CSPGCL mayapproach the Commission with specific scheme for cont<strong>in</strong>gency works for itsapproval. The cont<strong>in</strong>gency work done due to emergency may be allowed by theCommission for capitalization after prudence check.”It is also submitted that qualify<strong>in</strong>g an expense as normal O&M expense or Capital O&Mexpense may not be subjected to a “Laxman Rekha” test. Such discretion pass through narrowmarg<strong>in</strong>s and sometimes the discretion may need review <strong>in</strong> the backdrop of details related to thecase. Probably <strong>in</strong> the same spirit, while disallow<strong>in</strong>g certa<strong>in</strong> schemes, the Hon‟ble Commissionordered:“2.55. Capital O&M and capital civil schemes not approved by the Commission areshown <strong>in</strong> Annexure – 2. CSPGCL may get these schemes implemented under normalO&M expenditure, if found necessary. However, if CSPGCL is conv<strong>in</strong>ced that a fewof these schemes should come under capital O&M and capital civil schemes, thenthey may approach the Commission with detailed justification.”In view of the all the above aspects, proposals have been categorized <strong>in</strong> three segments &submitted herewith for approval by the Hon‟ble Commission.Page 5 of 46


Petition for approval of capital schemes FY 2011-12/12-133. CAPITAL INVESTMENTS IN EXISTING PLANTSCivil SchemesCSPGCL <strong>in</strong>curs capital expenditure for a variety of civil works that are undertaken at the plantsand the residential colonies for its employees. The broad heads under which capital expenditureoccurs under civil schemes is as follows:• For Ash Ponds or Ash utilisation (<strong>in</strong>cludes erection of new Ash Bunds/ rais<strong>in</strong>g of height ofexist<strong>in</strong>g Ash Bunds for dispos<strong>in</strong>g ash, utilisation of Ash <strong>in</strong> fill<strong>in</strong>g low ly<strong>in</strong>g areas, structuralworks etc.)• Investment <strong>in</strong> basic <strong>in</strong>frastructural work.• Increas<strong>in</strong>g green cover at power plants and <strong>in</strong> nearby areas as per PCB or Governmentdirectives to ensure environment protection.Capital O&M schemesThe generation function is a technology <strong>in</strong>tensive and capital <strong>in</strong>tensive function. Capital<strong>in</strong>vestments are essential for smooth and efficient operation of the plants. Some times due tochange <strong>in</strong> technology, the exist<strong>in</strong>g equipment become obsolete and arrang<strong>in</strong>g spares for theexist<strong>in</strong>g equipment become extremely difficult. Some times equipments need replacement <strong>in</strong>order to meet the economical and energy sav<strong>in</strong>g operation. At other occasions some majorequipment need replacement on completion of their useful life as may be prescribed by themanufacturer / as per standard <strong>in</strong>dustry practice. Further, at times there are changes <strong>in</strong> lawsuch as emission standards prescribed by the Pollution Control Board, which require certa<strong>in</strong>capital <strong>in</strong>vestment. All these <strong>in</strong>vestments have been covered under the Capital head. Further asper CEA guidel<strong>in</strong>e (para 4.3.1 of Guidel<strong>in</strong>es for R&M/ LE Works Oct‟09) , the expenditure onsuch replacement which have a useful period of less than five years are to be covered asrout<strong>in</strong>e repair and ma<strong>in</strong>tenance activity. Due care has been taken that none of the scheme fallunder this criterion.Considerable effort has been made to prepare the scheme wise details and reasonability of thesame has been ensured through rigorous <strong>in</strong>ternal discussions and deliberations. As a resultant,fresh civil schemes worth only about Rs. 34.48 Cr. are be<strong>in</strong>g proposed and new Capital O&M isbe<strong>in</strong>g restricted to only 48.50 Cr. as aga<strong>in</strong>st last year approved schemes amount<strong>in</strong>g Rs. 35.11cr. (total cost) for Civil and Rs.50.06 cr. for O&M .It is submitted that the estimates shall not betreated as the ceil<strong>in</strong>g limits. Leave is also craved for submission of additional schemes as andwhen such exigencies arrive. The <strong>in</strong>stant values <strong>in</strong>dicate the m<strong>in</strong>imum capital <strong>in</strong>vestment toensure economical, smooth and efficient operation of the plant.Page 6 of 46


Petition for approval of capital schemes FY 2011-12/12-13Apart from the above new schemes, it is also submitted that the estimated cost of the alreadyapproved schemes have also been updated. Respect<strong>in</strong>g the direction by the Commission thatlook<strong>in</strong>g to the high Capex plan <strong>in</strong> the <strong>in</strong>stant control period, the company shall endeavour torestrict the capital expenses to bare m<strong>in</strong>imum level essential for smooth, safe and efficientoperation, CSPGCL has deferred execution of even some of the approved schemes for timebe<strong>in</strong>g and the time be<strong>in</strong>g requirement is be<strong>in</strong>g met through repair works <strong>in</strong>stead of majorreplacement. It may be appreciated that cost mentioned aga<strong>in</strong>st the schemes are estimatedcost and may like to change dur<strong>in</strong>g implementation. Hence CSPGCL may be allowed to executethe scheme on actual cost and variation <strong>in</strong> cost shall subsequently be submitted to the Hon‟blecommission for sett<strong>in</strong>g off tariff.Renovation & Modernisation Scheme :Apart from capital O&M & civil schemes, generat<strong>in</strong>g plants need to take up renovation &modernisation (R&M) work for better and safe operation of the plant. In this respect CSPGCL issubmitt<strong>in</strong>g scheme for augmentation, ma<strong>in</strong>tenance & up gradation of Fire Safety/Protectionsystem for Coal handl<strong>in</strong>g plant, HTPS, Korba West amount<strong>in</strong>g Rs. 15.60 Cr. Project report isenclosed as Annexure - IV4. THE PROPOSALSThe chapter provides <strong>in</strong>formation on the quantum of <strong>in</strong>vestment that will be undertaken byCSPGCL dur<strong>in</strong>g FY 2011-12 on capital O&M / Civil works. It is to submit that consider<strong>in</strong>g thetime required <strong>in</strong> procurement and manufactur<strong>in</strong>g of eng<strong>in</strong>eer<strong>in</strong>g <strong>in</strong>tensive items, <strong>in</strong>vestment maypartly spread to FY 2012-13. Proposals have been compiled on plant wise scheme wise basis,however based on the nature of proposals they have been bifurcated <strong>in</strong>to follow<strong>in</strong>g heads:• New Schemes for capital O&M work (<strong>in</strong>clud<strong>in</strong>g emergency works) - Annexure- I• New Schemes for capital Civil work (<strong>in</strong>clud<strong>in</strong>g emergency works) - Annexure -II• Update on already approved schemes - Annexure-III• New Scheme for R&M work (Project Report) - Annexure -IVApart from the above the CSPGCL submits that there are two critical schemes which areessential to ensure un<strong>in</strong>terrupted generation at Korba East and Korba West. These schemesrelate to the rais<strong>in</strong>g of Ash pond from 340 mtr to 343 mtr at Lotlota HTPS Korba West (cost<strong>in</strong>gRs. 1.7 Cr.) and 3 rd stage rais<strong>in</strong>g of Podimar ash bund Phase –II, Podimar A& B at KTPS KorbaEast cost<strong>in</strong>g Rs. 3 crs. These schemes are expected to be completed by Mar 2014 and work onthe schemes shall start <strong>in</strong> 2012-13. As no expenditure is expected <strong>in</strong> the FY 2011-12, hencethese schemes have not been <strong>in</strong>cluded <strong>in</strong> the above proposals. However at the same timelook<strong>in</strong>g to the criticality and importance of ash dump<strong>in</strong>g system (as is evident from the NTPCKorba crisis) it is imperative for the utility to <strong>in</strong>itiate plann<strong>in</strong>g and adm<strong>in</strong>istrative work <strong>in</strong> advance.Page 7 of 46


Petition for approval of capital schemes FY 2011-12/12-13Petitioner humbly request that commission may k<strong>in</strong>dly accord <strong>in</strong> pr<strong>in</strong>ciple approval to take upthese schemes forthwith.F<strong>in</strong>ancial projections of CapexAs per historical trend, the Civil and Capital O&M schemes are expected to be funded entirelyfrom <strong>in</strong>ternal accruals. However, subject to suitable market conditions, CSPGCL may exercisedebt f<strong>in</strong>anc<strong>in</strong>g as applicable under the relevant regulations. For above schemes, no grant isexpected from any source.5. PRAYER :-In light of the above submissions, it is prayed that the Hon‟ble Commission may k<strong>in</strong>dly allow theproposals summarised at para 4 „Proposals‟ of the petition. Further look<strong>in</strong>g to the unpredictablenature of such works leave is also craved for additional submissions as and when suchexigencies arise.CSPGCLThroughPlace : RaipurDate : ……(S.K.

DESCRIPTION:The site for 4x210MW Korba West Thermal <strong>Power</strong> is located <strong>in</strong> the district of Bilaspur <strong>in</strong>Chattisgarh at a distance of about 15 km from Korba Railway Station. The Korba Railway station is on theChampa-Korba-Gervra Road section of the South Eastern Railway. A broad gauge railway l<strong>in</strong>e with asid<strong>in</strong>g connects exist<strong>in</strong>g power station on the East Bank with Korba Railway station is exist<strong>in</strong>g and can beutilized for transport<strong>in</strong>g material. The site is about 6 Kms from the exist<strong>in</strong>g <strong>Power</strong> House No II situated onthe eastern bank of Hasdeo River and is connected by an all weather road <strong>in</strong>terl<strong>in</strong>ked with the state &National High ways.The <strong>Power</strong> Stations unit # No. 1 to 4 of 210 MW was commissioned <strong>in</strong> the year from 1982 to 1986.As per the Project report of the DCPL, the consultant for the then MPEB, has summarized the FireProtection system <strong>in</strong> their “Detailed Project Report”, which are reproduced as belowThis system has been designed consider<strong>in</strong>g four (4) nos. 210 MW units. The hydrant systemconsists of a large network of pipes, both underground and over-ground, which feeds pressurized waterto outdoor and <strong>in</strong>door hydrant valves. These hydrant valves are located throughout the entire powerstation and also at strategic locations with<strong>in</strong> power house and other build<strong>in</strong>gs. Hose pipes of suitablelengths, fitted with standard accessories like branch pipes, nozzles etc, are kept <strong>in</strong> the hose houses. Incase of fire, these hoses are coupled to the hydrant vales and water jet is directed towards the fire. Water<strong>in</strong> the complete hydrant system as well as <strong>in</strong> the H.V Spr<strong>in</strong>kler system is kept pressurized by automatichydro pneumatic water pressur<strong>in</strong>g arrangement consist<strong>in</strong>g of a jockey pump, air compressor and hydropneumatictank. In the event of fire tak<strong>in</strong>g place when the hydrant valves are opened <strong>in</strong> any part of thenetwork, the fall <strong>in</strong> the header pressure will br<strong>in</strong>g the pumps <strong>in</strong>to operation automatically to supply waterto the hydrant system. Failure to start the pump on demand shall result <strong>in</strong> further fall <strong>in</strong> header pressureand this shall actuate the next pump to start automatically and soon. Thus an automatic sequentialstart<strong>in</strong>g arrangement has been <strong>in</strong>corporated <strong>in</strong> the system design. Pumps can also be started manually <strong>in</strong>case of emergency but can be stopped only manually.02.
