ENERGY CONSERVATION ACHIEVEMENTS
HIGHLIGHTED IN THE PROPOSAL
ENERGY AWARDENERGY 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
ENERGY AWARDENERGY 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 AWARDENERGY 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
Shevapet TE Building Salem
POWER PLANT
Replacement of 2000 A Conventional power plant with SMPS power plant
Existing plant Scrapped. New plant awaited
Target for replacement: Mar’08
POWER PLANTPOWER PLANT
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
Calculations
POWER PLANTPOWER PLANT
Saving in Energy Consumption per annum = 19kW x 365 x 24 = 166440 units
Cost of Energy per unit = say Rs 5/-
Savings per annum for BSNL = Rs. 8,32,200/-
Calculations
POWER PLANTPOWER PLANT
Cost of new Power plant being enquired to calculate the pay back period of this EC measure
Calculations
AC AC UNITSUNITS
Outlived AC units Replacements
Conf Hall Co axial Room
Existing Capacity
9 TR 72 TR
Proposed Capacity
7.5 TR Heat Load study being conducted (approx. 24 TR is sufficient)
TRANSFORMERTRANSFORMER
Replacement of 750 kVA oil cooled transformer with 400kVA resin cast transformer Age of Existing Transformer > 20years
750kVA 400kVA Diff
Core Loss 3450W 1840W 1610W
No Load Loss data
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
TRANSFORMERTRANSFORMER
PUMPSPUMPS
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
PUMPSPUMPS
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 AWARENESSGENERAL 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.
THANK YOU
