2. Energy conservation activities be carried out by employees Save Electricity bill by using Electrical equipments within Low rate time zone. At present Rates are as shown in table ( 2011) Turning off lights and air-conditioning in the rooms not in use Energy conservation during room cleaning Switch OFF unwanted lights during day time Instructions and procedures to save energy RD PATIL CE ROC 18.00-22.00 ZONE D Rs 7.45 + 1.10 per unit + TAXES 09.00-12.00 ZONE C Rs 7.45 + 0.85 per unit + TAXES 06.00-09.00 12.00-18.00 ZONE B Rs 7.45 per unit + TAXES 22.00-06.00 ZONE A Rs 7.45 - 0.85 per unit + TAXES

3. How to figure Kilowatt Hours ( UNITS ) For Single Phase : Watts = Volts x Amps. X cos Φ KW = Volts x Amps x1000 For Three Phase : Watts = 1.73 x Volts x Amps. X cost Φ KW = 1.73 Volts x Amps /1000 x X cos Φ Simple thumb rule: 1) 100 wh = 100 Paisa / hr for commercial rate 2) 1 KWH = 1 unit = 1000 wh = 1000 paisa/ Hr = Rs 10 per Hr RD PATIL CE ROC
