  1. ENERGY AWARD PROPOSAL FOR NATIONAL ENERGY CONSERVATION AWARD 2007 Shevapet TE Building, Salem

  2. ENERGY AWARD Presented by: S. Senguttuvan EE(E), Salem

  3. ENERGY AWARD Proposal Submitted Based on the Energy Audit Studies Conducted by • Shri. V.P.Gupta, PCE(E), Energy Auditor • Shri. S.P.S. Neemrana, SE(E), Energy Auditor • Shri. S.Francis Xavier, EE(E) • Shri. S.Sathyanarayanan, SDE(E), Energy Auditor • Shri. C.R.Sreenivasan, SDE(E) • Shri. S.Ravindrakumar, JTO(E) • Shri. R.Venkatesh, JTO(E)

  4. ENERGY AWARD ENERGY CONSERVATION ACHIEVEMENTS HIGHLIGHTED IN THE PROPOSAL

  5. ENERGY AWARD 1.Rationalisation of DC load • Diversion of Exchange loads from E10B to EWSD and scrapping E10B • Savings Achieved due to the above measure= Rs 11,68,000/- per annum • Savings in kWH = 23.36kWH

  6. ENERGY AWARD 2.Rationalisation of CMD • CMD reduced from 400kVA to 300kVA • Savings Achieved due to the above measure= Rs 3,60,000/- per annum

  7. ENERGY AWARD 3.Improvement in Power Factor • Power Factor Improved from 0.99 to unity by switching off excess lighting /inductive loads and frequent monitoring. • Savings Achieved due to the above measure= Rs 30,362/- per annum

  8. Post Audit Measures Shevapet TE Building Salem

  9. POWERPLANT Replacement of 2000 A Conventional power plant with SMPS power plantExisting plant Scrapped. New plant awaitedTarget for replacement: Mar’08

  10. POWER PLANT Calculations η of old PP = 75%Power consumed by Eqpt = 92kWStandard η of SMPS PP = 95%Power Consumption by new SMPS = 75% x 92kW / 95% = 73kWDiff in Power consumption = 92-73 = 19kW

  11. POWER PLANT Calculations Saving in Energy Consumption per annum = 19kW x 365 x 24 = 166440 unitsCost of Energy per unit = say Rs 5/-Savings per annum for BSNL = Rs. 8,32,200/-

  12. POWER PLANT Calculations Cost of new Power plant being enquired to calculate the pay back period of this EC measure

  13. AC UNITS Outlived AC units Replacements

  14. TRANSFORMER Replacement of 750 kVA oil cooled transformer with 400kVA resin cast transformerAge of Existing Transformer > 20years No Load Loss data

  15. TRANSFORMER Annual Savings in kWH=7050 kWH(operation of transformer for six months per year)Cost of new Transformer being enquired to calculate the pay back period of this EC measure

  16. PUMPS Water level controllers for all centrifugal pumpsThree types of controllers identified. 1. Switching off the pump automatically, when the OH tank is full 2. Starting the pump when level in the OH tank is LOW and switching it off when the OH tank is FULL 3. Similar to (2) above & stopping the pump, if water in the source tank (sump) depletes

  17. PUMPS Prices and models suitable for the building are being enquired.Currently, the pumps are switched off only after water overflows from the OH tank at 7th Floor and attracts staff nearby

  18. GENERAL AWARENESS • The PCE(E), Chennai addressed a gathering of over 125 executives on 15/06/2007 to disseminate information on EC act & EC Building Code. • Three Core Group meetings conducted by GMT, Salem SSA during 2007. • The GMT, Salem has approved the proposal for MD controller • All the staff in the building were found to be highly energy conscious and cases of energy wastage due to negligence were found to be minimal.
