   Name: Ramchandra V Nesari  Designation: Dy. General Manager (Chemicals)Company name: Rashtriya Chemicals & Fertilizers Ltd.Complete address: 29A, Technical Building,RCF, Trombay Unit,Chembur, MUMBAI- 400074  Fax no: 022-25522235Email ID :nesarirv@vsnl.net,rvnesari@rcfltd.com  Introduction: In order to check the statistical data given for its validation, attempts were made to collect thedata from various sources. However, it must be admitted that attempts of one month’s searchfrom 27.08.2004 to 27.09.2004 yielded a vast amount of data. But the data relevant to the Issuewere far from the required satisfaction. The sources of data were:1. Annual Reports of Power Ministry2. Reports/ Annual Reports of CEA3. Annual reports of Ministry of Agriculture4. Reports of Ministry of Commerce and Industries5. Newsletter/ reports/ databank of IEEMA6. Published papers on relevant topics7. Economist Intelligence Unit repotsThe given Table of the Issue has been modified to include correction where they were felt to be.required. Wherever, the given figures were confirmed to correct, the same has been retainedwith blue colour. Wherever the figures of the data have been changed, they are presented in redcolour  to differentiate from the srcinal figures, which are retained in a bracket . The source of thedata is given below the changed figures. Some Observations on the data discrepancy: 1. aigonline.com in its report dated 26 th May 2004 gives following sale figures for followingelectrical items:In the bracket the figures of the Issue#20 are given)  Air-conditioners sales in the year 2003: 0.98 million (0.80 million)  Refridgerator sales in the year 2003: 3.60 million (3.40 million)  Ceiling fans sales in the year 2003: 15 million: (12.50 million)Indiandata.com gives following production figures of following electrical items:  Electrical fans (IPP): 5.5357 million  Electrical fans (SS) : 3.6045 million-----------Total 9.1402 million2. Pumps manufacturers:Business Line Internet edition dated 6 th Dec. 2002 mentions over 150 medium sizedmanufacturers including big players such as KSB, Kirloskars. tifac.org.in mentions pumpmanufacturers strength as more than 500.3. CII in its data on “Pumps Industry” gives the graphical representation of its growth asfollows:  1997-98 to 1998-99: 12%1998-99 to 1999-2000: 10%1999-2000 to 2000-01: 7.20%4. Distribution transformers figures are based on a paper titled “Determination Analysis of Energy Conservation Standards for Distribution Transformers.”1 STANDARDS & LABELLING PROGRAMME – ELECTRICITY SAVING POTENTIAL PRIORITY Equipment Annualelectricityconsumptionof equipmentGWh 1 Annualsales of equipmentin 2002-03millionsAnnualelectricityconsumption of newstockGWh 2 Electricityconsumption of newstock tototalelectricity% 3 Estimatedimprovement inefficiencyof newstock% 4 Annualelectricity savingsGWh 5 Organisedsector  6 %Informalsector  7 % (1) (2) (3) (4) (5) (6) (7) (8) (9) Agriculturalpump sets 8 84,486(CEA)(118,059)0.8 6,000 1.1 38 2,280 55 45 Fluorescenttube lights ?19016,720 3.0 10 1,672 90 10 Industrialmotors 114,959(CEA)(119,273)4,350 MW(IEEMA)(4,103 MW)26100(24,618)4.4 5 1,231 98 2 Refrigerators 25,5503.42,172 0.425 (WEA)(32)695 100 0 Air conditioners 12,1130.82,100 0.410 (WEA)(21)441 85 15 Ceiling & tablefans ? 12.5(?)1,313 0.2 21 2766 (Indiandata)94(Indiandata) Industrialpumps 9 18,9068%(tifac.org.in)20% 10 3,781 0.7 7 265 90 10 Ballasts ? 30 720 0.1 31 223 30 70 Industrial fans 18,167 15% 2,725 0.5 8 218 85 15 Distributiontransformers 6400(BEEestimate)(12,709)16,600 MVA843 0.1 24 202 50 50 Geysers (hotwater) ? 0.8 864 0.2 17 147 ? ?

Similar estimates were made for other equipment.Column 4 = Annual electricity consumption of new stock = column 3 * 1500 hours per year *average 5 kWh consumption per hour = 6000 GWhColumn 5 = Electricity consumption of new stock to total electricity = Column 4/ 562572 *100 =1.1%Column 6= Estimated improvement in efficiency of new stock = 5kW pump replaced by 3.1 kWhigh efficiency pump delivering the same quantity of water = 100* (5-3.1)/5 = 38%(Column 7 = Annual electricity savings = Column 4* column 6/100 = 2280 GWh) 9 For industrial pumps, fans and compressors the efficiency improvements are only due toequipment and not motors, to avoid double counting. 10 Figures in % in these columns represent sales growth rate of the equipment2Notes:CEA: Central Electricity AuthorityWEA : World Energy AgencyCFL lamps consumption taken at 16 Wh for 5 hours a day and 365 days in a year. CFL sale isbased on the figures mentioned in the preliminary report of Ministry of Commerce and Industrieson the representation of Indian CFL manufacturers.
