Tariff Rate for Domestic Consumers

Lighting Loads : 

Lighting Loads Types of Lamps available Incandescent Lamp (40w, 60w, 100w) Fluorescent Lamp(40w – Actually 55w) Compact Fluorescent Lamp (CFL) (9w,11w,16w)

Slide 6: 

Case Study 1: A house with seven fluorescent lights each 55w Portico (6.30p.m. to 9.30p.m.) – 3 Hrs Hall (6.30 p.m. to 11.30 p.m.) – 5Hrs Kitchen (6.30p.m. to 9.30p.m.) – 3 Hrs Reading/Studying – 3Hrs

Slide 7: 

Total Power Consumed = 55 X 3 lamps X 3hrs + 55 X I Lamp X 5Hrs + 55 X 4 lamps X 0.5 Hrs. = 880 w/day = 880 X 60 days = 52800 w/bill = 53 units

Slide 8: 

If replaced by CFL Portico – 9w Hall – 16w Kitchen – 11w Reading/Studying – 55w Others – 9w each

Slide 9: 

Total Power Consumed = 55 X 1lamp X 3hrs + 9 X I Lamp X 3Hrs + 16 X 1 lamp X 5 hrs + 9 X 4lamps X 0.5 hrs. = 290 w/day = 290 X 60 days = 17400 w/bill = 17 - 18 units

Slide 10: 

Energy saving Is About 53 – 17 = 36 units per bill Just in lighting load alone

Case Study 2:- Fans : 

Case Study 2:- Fans Using conventional Regulator – 60W (At position 3) 2. Using Electronic Regulators – 36 W (At Position 3) Net Energy Saving Per day – 24 x 12 Hrs – 288 w/day No. Of Units Can be Saved Per Bill – 18 Units

Slide 12: 

Case Study 3: Computers Approx. Power Consumption – 120W Monitor Power Consumption - 70 W (Approx.) Suggestion: By Automatically Switching off the monitor if not in use we can save 50% of Power Consumption

Slide 13: 

Other Suggestion; Careful handling of Refrigerators Proper loading of Washing machines Grinder, iron box, greaser etc

Slide 14: 

Conclusion: A saving of 60 units per bill is possible by adopting these methods
