  • 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


Energy award5
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


Energy award6
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


Post audit measures
Post Audit Measures

Shevapet TE Building Salem


Power plant
POWERPLANT

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


Power plant1
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


Power plant2
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/-


Power plant3
POWER PLANT

Calculations

Cost of new Power plant being enquired to calculate the pay back period of this EC measure


Ac units
AC UNITS

Outlived AC units Replacements


Transformer
TRANSFORMER

Replacement of 750 kVA oil cooled transformer with 400kVA resin cast transformerAge of Existing Transformer > 20years

No Load Loss data


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


Pumps
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


Pumps1
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


General awareness
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.
