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

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 ]

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

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

AWARENESS PROGRAMME

ENERGY CONSERVATION AWARENESS WILL BE CREATED THROUGH PROGRAMMES AND SLOGAN STICKERS

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

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