IMPORTANT RECOMMENDATIONS ( Stage No. 1 )

1. Automatic power factor controller / M.D. controller is recommended to be installed at main panel board.

2. If one Generator is installed only for boilers, the shoot up

M.D. (604 KVA) in one month can be controlled. The 11 Month bill based on 75% M.D. (604 KVA) can pay back the generator’s cost only in one year. ( the Generator is to be hired for one month )

3. Only one Transformer of 500 KVA or 250 KVA is to be operated at a time alternately during off session period.

( Stage No. 2 )

4. If all the 1628 no of tube lights in 387 rooms whose total working hours 4380 will consume 199658 units. The pay back period will be two years.

( Stage No. 3 ) 5. If solar system is put in operation then the maximum recorded MD even in session period will be reduced to the Sanctioned MD i.e. 300KVA.

ENERGY SAVING CALCULATIONS

& COST ECONOMICS

THE STEPS OF ENERGY AUDIT: Step. 1 Barriars to energy conservation efforts finance, economical

efforts and technical. Step. 2 Identification of potential areas for energy conservation. Step. 3 Issues supporting conservation. Step. 4 Future conservation policy. Step. 5 Results achieved.

13

ENERGY CONSERVATION THROUGH AWARENESS

The present tariff structure The 12 Nos. of M.S.E.B. monthly bills were studied in view of energy conservation.

OBSERVATIONS:

1) The M.D. Charged were 575 & 604 KVA in the month of December 2002 & 2003 respectively. Throughout the year M.D. recorded is charged as 453 KVA i.e. 75% of maximum-recorded M.D. only in one month.

2) The actual recorded M.D. during the 11-month is maximum 324 KVA in the month of February 2004 and in remaining 10 months, it is less than 200 KVA.

A. The additional KVA charged per month are (453-300)=153 KVA Amount paid in excess every month is Rs. 153 X 330 = Rs.50490/- & per annum Rs.605880/-.

B. But if peak demand is controlled then the potential of saving will be as follows.

PROPOSED MEASURES If one 125 KVA DG set along with AMF panel is provided. The cost of generator will be recovered only in 2 year against the M.D. charges paid at present. The scheduling of load is essential to avoid the M.D. during peak time.

Total connected Load 1050 K.W. Water Heater Load 774 K.W. i.e. 73% of Total Load 1) GENERATOR : ( A ) Hired :-- 125KVA at 0.8 P.F.

Per day units to be generated during session period = 125 X 0.8 X 8 hrs = 800

During session period (20 days) = 16000 units

Cost of Units purchased from MSEB = 0.448 Lakh Cost of M.D. 100 KVA = 0.33 LakhTotal Cost of MD for 11 months = 2.7225 Lakh Total Savings = 3.50 Lakhs

Operational Cost : Rental Charges @ Rs. 5000 x 20 Days = 1.00 Lakh Diesel Cost 25 Ltrs. Per hour x 8 hours X 20 Dys x Rs. 30 = 1.20 Lakhs Total Cost = 2.20 Lakhs ( B ) Purchased : Cost of Generator = Rs. 6.00 Lakhs Operator + Diesel in Session Period = Rs. 1.25 Lakhs ______________________________________________________ Total = Rs. 7.25 Lakhs Saving ( As above ) = Rs. 3.50 Lakhs Pay Back = About 2 Years.

2) PUMPS:- The Total H.P. of pumps in operation 37.5 H.P. i.e. 28KW. Maintaining power factor as 0.95,KVA demand 29.5 KVA 168 units are consumed by pumps in 6 hour operation per day. Units consumed in one month (5040 Units) if operation time of pump is changed from peak to non peak.

Rebate @ Rs.-0.75 per unit Rs. 3780.00 M.D.Benefit @ Rs. 330 per KVA X 300 KVA Rs. 9990.00 Rs. 13770.00 The Power factor of motor is measured as 0.86 It is proposed to be improved to 0.95 The losses will be reduced by 19% Losses = 1 – (0.86) X (0.86) = i.e. 19% (0.95) X (0.95) 19% of 5040 Units = 958 Units 958 Units @ Rs. 2.8.Per Units = Rs. 2681.00 Total Benefit per month Rs. 16751.00

Annual Saving will be about Rs. 2.0 Lakh.

16

FOR FURTHER SAVING(PUMPS)

a) The master tank capacity is to be changed 3 times. At present all tanks are of same capacity.

b) The present number of joints, elbows, tees & valves are recommended to be reduced proportionately.

c) The overflow Indicator & Water Level Indicator in Master Tank are necessary.

d) The required capacity of capacitor, which was needed to be installed, are now installed.

e) The two main valves in outgoing pipeline were out of order since long. The concerned Deputy Engineer PWD (Civil) had replaced the same so that wastage of water is saved. i.e. The required additional energy for pumping the wastewater. Similarly the water leakages in pipes and storage tanks are required to be stopped.

f) One 15 H.P. (11 KW) motor tested in normal conditions and then by installing the invertor for incoming supply. The difference in ‘No Load losses’ are measured as 2 KW.

g) If energy efficient motors of same capacity are installed then minimum saving will be as follows:

37.5 H.P. X 0.746 KW = 28 KW No. of units consumed: = 28 KW X 6 Hrs X 30 X 11 =55440 units + 10800 (during session) = 66240 units.

i. Efficiency of motor is 5% more. So saving in units 3312 i.e. Rs.9274/- Payback period will be around 3 t0 4 years depending upon the hours of operation.

ii. If invertor is used for quality of supply the units saved will be

2 KW X 6 Hrs X 365 days = 4380 i.e. Rs.12264/-. The cost of invertor will be paid back during 3 to 4 years for 15

H.P. motors. The total cost of saving for units consumed = Rs. 31218.00

17

3) WATER HEATER:- The thermostats are at present set to 70 degree Celsius. The resetting of thermostat at 50 degree Celsius is made the expected saving in units per water heater 0.813 Units. 20 degree Celsius X 35 Ltr. = 700 Kcal 1 KW = 860 Kcal. Monthly saving

0.813 X 0.2 X 387 X 30 = 9440 Units. (Off session 20 % occupancy)

FOR LIGHTING SYSTEM Step.1 Providing lighting levels as per required tasks. Step.2 Additional sources for difficult tasks. Step.3 Selecting proper lighting sources. Step.4 Control and maintenance.

4) STREET LIGHTS:-

Total load is 9.72 The timer are installed at 3 places which reduces the wastage of consumption for 2 hour. Total saving will be 9.72 X 2 X 30 = 585 Units. i.e. Rs.585 X 12 X 2.8 = Rs.19656/- The cost of 3 nos of timer is Rs.20000/-. The payback period is around one year.

18

5) PASSAGE LIGHTS - 90 Nos. :- (40 Watts tube light)

(10 Lights for Each passage) if the CFL (60 Nos) of 2 x 9 Watts are proposed then the Net Saving in units (for 12 hour) will be (90 X 55 X 12 – 60 X 18 X 12) 30 days 1458 Units. Reduction in M.D. (90 X 55 – 60 X 18)/1000 = 3.88KVA i.e. 4KVA Cost of 1 CFL of 2 X 9W is Rs.743/-. Total investment Rs.44580/- Saving 1458 X Rs. 2.8 X 12 months = Rs.49000/-

+ 4KVA X 12 X 330 = Rs.64840/- Payback period 6 months.

6) BATH ROOM LIGHTS - 387 Nos.:-

1 X 40 W Tube light and one night lamp of 10 Watts is existing at present. If in each bathroom CFL of 9 Watts and one Watts Night Lamp is installed the difference in consumption in Each room will be. (55 + 10 – 10) Watts = 55 Watts per room considering the 20% occupancy units saved will be.

0.20 X 387 X 58 X 12 Hour X 30 Day = 1616 Units 1000

Reduction in M.D. = 58 X 0.2 X 387 /1000 = 5 KVA

During Session =25KVA

i.e.8080 Units

Cost of CFL - 7W + 1W (Night Lamps) = Rs.500/- Total cost investment for 387 rooms = Rs.1.95

Lakhs Saving in units in Rs.0.55 Lakhs + Saving in M.D. Rs.

0.20 Lakhs. Payback Period – 2 years and 6 months.

19

7) ROOM LIGHT - 387 Nos:-

The Master switch is installed for each room but it is not being used to switch off the lights when the occupant leaves the room. So the sticker on door is pasted in side and outside of the door as

“SWITCH OFF ELECTRIC SUPPLY WHILE LEAVING THE ROOM”

If in each room the master switch is installed which operates if the keys are inserted in, then the cost of installation of such 387 nos. of switches will be @ Rs.500 per switch i.e. Rs.1.94 Lakhs.

8) CLASS IV QRTS (32 Nos) & CLASS III QRTS 12 Nos.:-

The supply to these quarters is unmettered. The separate 44 No. of meter from MSEB are proposed to be installed if MSEB agree for independent & separate supply then the saving will be as follows:

a) Reduction in M.D. for 50 KW Load. Considering the diversity factor as 50% = 25KVA

b) Reduction in units consumption minimum 44 X 100 = 4400 Units. ( Minimum ) If separate 44 Nos of metes are installed by M.S.E.B. The total cost for 44 quarter will be Rs. 3.50 Lakh. The saving will be 25 KVA X 12 X Rs.330 = Rs.1 Lakh The saving in Rs. for units = Rs. 2.5 Lakhs The Payback period will be 12 months.

If the above request is not considered by M.S.E.B as the MLA Hostel is a HT consumer the one additional three phase energy meter is proposed to be installed to recover the charges for the units consumed by individual occupants.

20

9) CANTEEN:- The separate meter for canteen is already installed in pump room. But the unit consumption charges are not being fully recovered by Civil Department from the Occupant (Only ¼ th of recorded consumption is recovered).

The consumption of units per month is about 2700 Units.

10) TRANSFORMER:-

The Transformer 3 Nos. are tested for its efficiency and found to be working efficiently.
