17. REPLACEMENT OF CONVENTIONAL POWER PLANT WITH SMPS POWER PLANT

18. THE EXISTING CONVENTIONAL TYPE POWER PLANT HAS BEEN REPLACED WITH SMPS POWER PLANT RESULTING IN A SAVING OF RS.62,550/- PER YEAR

19. REPLACEMENT OF CONVENTIONAL POWER PLANT WITH SMPS POWER PLANT Power saving by replacing conventional power plant by SMPS power plant Description Conventional Power plantSMPS power plant Efficiency of power plant82.64%95% Output power ( KW)7.5 Input power (KW)9.087.89 Total energy consumption/year (Kwh)7954169116 Total cost of the energy (Rs.)477246414696 Savings in Energy /year (Kwh) 10425 Savings in cost/year (Rs.) 62550

20. REPLACEMENT OF DEFECTIVE CAPACITORS

21. THE DEFECTIVE CAPACITORS IN THE POWER FACTOR IMPROVEMENT PANEL HAVE BEEN REPLACED RESULTING IN A SAVING OF RS. 30,799/- PER YEAR. POWER FACTOR ALWAYS > 0.98

22. REPLACEMENT OF PACKAGE AC UNITS 4+2 X 7 TR REPLACED WITH 3+1 X 7 TR

23. REPLACEMENT OF PACKAGE AC UNITS THE EXISTING 4+2 X 7 TR PACKAGE AC PLANT HAS BEEN REPLACED WITH 3+1 X 7 TR PACKAGE AC PLANT RESULTING IN A SAVING OF RS.1028500/- OLDNEW EXPENDITURE

25. PROPOSED ENERGY SAVING MEASURES IN 2007-08 1. CHANGE OF EB TARIFF OF 21 NOS S/Q 2. REPLACEMENT OF FL. FITTINGS WITH ENERGY EFFICIENT FITTINGS 3.PROVISION OF WATER LEVEL CONTROLLER FOR PUMPS 4. CREATING AWARENESS AMONG STAFF BY CONDUCTING PROGRAMMES & THROUGH SLOGANS

26. CHANGE OF EB TARIFF OF S/Q AT PRESENT 21 NOS S/Q ARE BEING FED FROM SUB STATION & ENERGY COST IS RS.5/- PER UNIT ALL ELECTRICAL WORKS FOR GETTING SEPARATE SERVICE CONNECTION FOR S/Q ARE COMPLETED WHEN SERVICE CONNECTION WITH RESIDENTIAL TARIFF IS EFFECTED THERE WILL BE A BI-MONTHLY SAVING OF RS 14,700/- [ 21 S/Q X (RS 5 - RS 2.8) X 250 UNITS ]

27. WATER LEVEL CONTROLLER FOR PUMPS NEARLY 225 EMPLOYEES ARE WORKING & 13 NOS PUMPS ARE AVAILABLE ALL THE PUMPS ARE BEING OPERATED MANUALLY THERE IS A GOOD SAVING POTENTIAL BY PROVIDING WATER LEVEL CONTROLLER FOR THE PUMPS

28. INSTALLATION OF ENERGY EFFICIENT LIGHT FITTINGS 598 NOS TWIN FITTINGS & 316 NOS SINGLE FLUORESCENT TUBE LIGHT FITTINGS ARE AVAILABLE CONNECTED LOAD OF THESE FITTINGS WORKS OUT TO 60 KW IT HAS BEEN PROPOSED TO REPLACE THE ABOVE WITH ENERGY EFFICIENT FITTINGS IN A PHASED MANNER ON COMPLETION OF THE TASK THERE WILL BE A REDUCTION OF 18 KW OF LOAD

29. AWARENESS PROGRAMME ENERGY CONSERVATION AWARENESS WILL BE CREATED THROUGH PROGRAMMES AND SLOGAN STICKERS

30. APPLICATION SENT IN VIEW OF THE ABOVE MEASURES & ACHIEVEMENTS & AS PER THE INSTRUCTIONS OF THE PCE(E) & SE(E), APPLICATION FOR THE ENERGY CONSERVATION AWARD HAS BEEN SENT TO BUREAU OF ENERGY EFFICIENCY

31. WE HOPE THAT CTO COMPLEX MADURAI WILL RECEIVE THE ENERGY CONSERVATION AWARD FROM BUREAU OF ENERGY EFFICIENCY
