EXECUTIVE SUMMARY

Introduction : There is an ever increasing wide gap between ‘Supply and Demand’ inthe “Electricity and Diesel “ Energy sectors, at a galloping speed. To mitigate this problem,a two way approach can be employed.

(1) Increasing the capacity addition to the Grid;

and (2) Decreasing the demand on the grid by Energy Efficiency/Saving methods.

By going in for Solution (1), huge capital investment is required with a range of Rs.6 - 8 Crores per MW for establishment of a Thermal Power Station with an incubationperiod of 3 - 5 years depending on the size of the project. Also, it depends on theavailability of funds, fuel , water, land and transport; Pollution control - environmentalfactors etc., Hence this cannot offer an immediate solution.

By going in for Solution (2), the following benefits can be reaped :

(a) Reduced demand on the grid on both KVA and KWH by adopting EnergyConservation measures;

(b) It is cost effective;(c) The capital investment is paid back from the accrued energy savings;(d) “ One Unit Saved is Two Units generated. ”(e) By using Energy Efficient equipments, the performance is improved giving the

benefits to the End-users;(f) The Service provider viz., the Municipality can remove Customer dissatisfaction

in order to achieve satisfaction and the final goal of Customer delight ! ;(g) In addition to cost savings in energy, savings on reduced failure replacements

due to use of ‘ long burning hours capacity type EE equipments ’.

(h) Breakdowns / failures get reduced drastically and work force utilized for preventivemaintenance works.

The Government of India is seized of the problem. Capacity addition will not offera “Whole, Total and Holistic” solution to meet the immediate needs and also thereare huge leakages existing by way of energy losses on both the Supply andDemand sides; i.e., Generation, Transmission and Distribution sides. Hence theElectricity Act 2003 through Electricity Act 2001 was passed which gives wide scopefor Energy conservation by Energy Audit with Demand Side Management. Forimplementation, the BEE have started the very ambitious program on the Municipal,Agricultural and SME industrial sectors.

Most of the Municipalities suffer for want of funds as 80 % of their O & M funds arespent as Energy bills on administrative buildings, WTP, STP and Street Lighting Systems.Even after meeting out these expenses, the performance of the Municipal system is not up tothe expected level, bringing more complaints on irregular supply of water; poor clearing ofsewage and the lack of safety and security to be offered by the Street Lighting system etc.,More failures and break down of water lines; water supplied without adequate pressure; StreetLight Lamp failures and not caring for reducing the down time in rectifying the defects, breakdowns etc. ; no preventive or routine maintenance works or inspection being carried out.There is no proper upkeep and maintenance of Complaints Register to bringimprovement in redressal of grievances of the public.

*************

‘Sagar’ is a medium town located in Madhya Pradesh State and about 75 Km awayfrom Bina Town. Being a backward area, the livelihood comes mainly from agriculture.

Population : 5,00,000 approx.

No. of Wards : 48

The town is governed and maintained by the Sagar Municipality. One CivilEngineer and one Electrical Engineer oversee the efficient functioning of the Street LightingSystem, Water Supply to the public and Municipal building maintenance works. 19employees of the Municipality are at hand for carrying out these works.

I. STREET LIGHTING SYSTEM :

Town Illumination :

The prime objectives are : (a) hold back the day;

and (b) to give a character to the town at night.

A well illuminated town gives :

(i) Safety : Safety for Walking, Cycling, Biking, Motoring etc., to thepublic thereby reducing accidents.

(ii) Security : Helps in prevention of thefts, crimes etc., thereby improvingcitizens’ life style — by offering freedom from fear.

Enhancement of night time ambience promotes business as well as social interaction.

The Madhya Pradesh State Electricity Distribution Company supplies Electricalenergy to the Municipality under various Account heads for the Service connectionseffected.

STREET LIGHTING :There are 5, 059 Nos. of Street Lights consisting of Tube lights,

Sodium Vapour and Metal Halide lamps, CFL and other lights and are beingmaintained by the Municipality’s employees. The spare materials for proper maintenanceare ordered by the Municipality and kept as stock.

STREET LIGHTS :Total Nos. of Service connections : 34

Approved total load : 621.5 KW.

Total Electrical consumption charges/month : Rs. 4, 76, 860 / -

Annual expenditure :

(a) Maintenance cost (labour) and,

(b) Replacement cost of defective / failedStreet lights / accessories : Rs. 7, 30, 000 / -(Materials’ cost)

Annual Maintenance Expenditure : Rs. 88, 00, 000 / -(Labour & Materials)

The existing arrangement of the Municipal Lamps mounted on MPEB leads to delayin rectification of failures. Line clear / Shut down has to be availed from MPEB. Theearthing system is also not up to the mark ; Street light cables used are of poor insulation ;leakages have been noticed and losses are on the high side.

II. Water Supply Scheme :

Sagar Municipality have established a Protected clear water supply scheme andmaintain Water supply to the residents of 29 wards.

(a) Raw water is pumped from the Raj Ghat River course by using 2 Nos. Motor Pumpsets ( 170 KW each ) operating in parallel for 17 Hrs. / day for 2 days with 1 daybreak. Additionally, 2 Nos. equivalent capacity Motor-Pump sets are available foralternate use / standby.

(b) The pumped raw water is connected via pipes to the Water Treatment Plantlocated about 2 Kms. away from the River water PH. The raw water now treatedat the Water Treatment Plant is passed on to the Clear Water Pump House. 2Nos. Motor-Pump sets ( 845 KW each ) operate in parallel for 17 Hrs. / day for 2days with 1 day break to pump the ‘Clear’ water to an elevated Reservoirlocated on a small hill top 8 KMs. away from the pump house. Here also 2Nos. equivalent spare Motor-Pump sets are available for alternate use / standbypurposes.

The elevated Reservoir’s outlets are connected to 6 Nos. Overhead Tanks viapipes ; water reaches these tanks by gravitation, which in turn distribute water supply tothe residents.

( c) There is one 33 / 6.6 KV - 400 V Sub - station with 2 Nos. 33 / 6.6 KV Transformersand 1 No. 33 KV / 400 V Transformer receiving power from MPEB with a Sanctioned /Contract demand of 1684 KVA in WTP and Clear water PH, supplying energy toboth Raw Water PH, WTP and Clear water PH.

Note : By operating 2 pumps each at RWPH & CWPH, the energy consumptionexceeds the MD of 1684 KVA by 868 KVA the Municipality incurs penalty and paysaround Rs. 24 lakhs. This can be saved as per IGEA done.

(d) In addition to this, 19 wards not covered by the Municipal water lines under waterService connections are served by supplying ‘Untreated’ water directly from 2Nos. Open well Pumps and Water Tankers and 13 Nos. Submersible Pumpswith open water Taps.

The schedule of water supply is delivery for 2 days with 1 day break.There are no complaints from the public and the performance is found to be satisfactory.

III. Municipal Buildings :The Municipality functions in 4 Nos. Buildings spread across the town.1. H.O - Nagar Palika Nigam2. Pavilion - Zone office I ;3. Zone office II ;4. Zone office III.The average annual billed consumption is 34,916 Units and the bill payable is Rs.

1,90,000. The lighting is maintained by the personnel of the Municipality.

IV. Disposal of Sewage :Sewage is let out on open canals built on the sides of the streets. The Municipality is

not maintaining them.

The chart shows the Municipality Budget Energy wise and the above scheme wise.Energy Bills received from MPEB are just passed and paid by the Municipality. Most ofthe Energy meters are not functioning. The energy usage and bills are to be checked andpassed. No complaints register is available at the site offices. Maintenance of the complaintsregister shall help the Municipality to review and bring down the down time of eachcomplaint ; Better co-ordination with the MPEB.There are three options before the Municipality :

Conclusion :

(1) The Municipality can reduce its Energy Budget from its existing level to % both onenergy & Operation & maintenance costs – saving is %.

As a first step, the 34 switch points have to be properly metered. The monitoring systemoperating on GSM Technology connected to a central computer, displaying of burning status,operating the switches on time slot basis, consumption details of each switch point so that themunicipality can have better control over consumption & burning status, redressal of complaints byreducing down time of each complaint. By this arrangement over all improvement of burning status,reduction in no. of complaints and down time of each complaint, and consumption in each switchpoint can be achieved. Municipality can bring all the lights on control gears & under monitoringsystem to give service to the public.

Energy saving, money saving in operation & maintenance cost, cash in-flow, out-flow and ARR arealso given in calculation and chart forms. From the above, Energy Audit Detailed project Report is aviable, profitable and bankable project.

(2) The funds can be obtained through banks wherever necessary(3) In addition to monetary saving, the services will be improved a lot to serve the public

with better water supply system and street lighting system.(4) This is a win-win situation to every body – The beneficiaries are :

Municipality – Cost reduction, better services

MPEB – Demand & unit reduction to be used for clearing pending newservice applications.

State Govt – Energy Bill reduction.

Central Govt – Energy Bill reduction.

Global – Environment protection by reduction of GHG emissions.

General public – Better services on STP – Better illumination, safety, security,reduction in accidents, better ambience, improved social

interaction & business, Environmental protection, etc .Optimum water supply.

4) Length of Dam - 1680 Meters.5) Rock Portion - 1280 Meters.6) River Bed Level - 495 Meters.7) Lower chill Level - 509 Meters.8) Highest Bed Level - 518 Meters.9) Max. Flood Level - 520.5 Meters.

The City’s requirement of water under the water Supply Scheme assessed as :(i) 15 MLD for the People of 29 Wards out of 48 Wards and,(ii) 5 MLD for the balance 19 Wards (through Tankers & open Line Taps).

The excisting Schedule of Operation of Motor Pumps sets at Raj Ghat Pump House is2 Nos. of 170 KW capacity each running at 17 Hrs / day for 2 Days with 1 Day break.

Pump Capacity = 2 x 1969 m3 / Hr.= 2 x 1969 x 1000 x 17= 67 MLD.

A single Motor Pump can meet out the Town’s requirement of 15 MLD. This notonly reduces the demand on the Transformers, the consumed Unit Charges and also improvesthe performance of the water supply Scheme, giving water to the public for all days with outany break.

By running one No. Motor Pump set only for 17 Hrs. per day continuously

(without any holiday) and operating the other spare pump sets cyclically daily,

Water pumped = 1 x 1969 x 1000 x 17

= 33, 473, 000 LD or

= 33 MLD.

This will be able to meet the Town’s requirement of 15 MLD.

The KW reduction due to running of only one No. pump for 17 Hours daily insteadof the existing running of 2 No. Pumps for 17 Hours daily for 2 days with one day breakis noted below:

MD reduction & KWhr reduction :

Actual Reading = 40 KWh x 120 / day when 2 motor-pumps operated in parallel.= 4800 KWh / day= 4800 / 17= 282.4 KW for 2 motor-pumps sets running.

By using 1 motor-pump = 282.4 / 2 KW

Reduction in Energy = 141.2 KW or say= 141 KW.

Therefore % Loading = ( 141 / 170 ) x 100= 83 %.

The PF measured is = 0.56.

For each Motor 80 KVAR- power capacitors are in service. Hence, the motors willoperate with 83 % loading which is in the higher efficiency region and does not require anyimprovement. These existing power factor correction capacitors are not enough in capacity.Adding 130 KVAR Capacitors may not be cost effective as energy reduction will be 2%only.

Recommendation :

The existing practice of running 2 No. pumps for 17 hours per day for 2 days withone day break can be stopped and instead 1 No. pump can be run for 17 hours daily withchange of spare pumps cyclically daily to meet the Town’s water requirements.

By the above, the MD as well as Unit reduction can be achieved to obtain EnergySavings.

Clear Water Pump House :

One No. Pump running for 17 Hrs daily can meet the Town’s requirements= 1 x 1875 x 17 x 1000= 31, 875 MLD or say= 32 MLD.

The KWh reduction and the KVA - MD reduction by running one No. pump set dailyinstead of running 2 No. pump sets for 2 days and with one day break are detailed below.

Energy Saving Calculations :

At Raj Ghat Raw Water PH :

KVA MD Reduction - 170 / 0.8 = 212.5 KVA

At WTP - Clear Water PH :

KVA MD reduction = 845 / 0.8= 1056 KVA by operating one motor-pump

instead of two motor-pumps.

Total KVA reduction by stopping one No. motor at Raw Water Pump House as wellas Clear Water Pump House is given below :

Total KVA reduction = 212.5 + 1056= 1268.5 KVA

Without any investment, by stopping one motor pump set and running only one motorpump daily at Raw Water & Clean Water Pump House, Energy reduction will be :

Total KVA reduction = 1268.5 KVA

The Contract Demand with Utility = 1684.0 KVA

Sagar Municipality unnecessarily pays penalty every month and this can be avoidedby containing the MD to the level of CD - 1684 KVA.

KWh reduction :

Annual Energy Saving = 170 KW x ( 68 - 51 ) x 10 x 12 +845 KW x ( 68 - 51 ) x 10 x 12

= 3, 46, 800 + 17, 23, 800= 20, 70, 600 Units

Annual Monetary benefit = Rs 2.95 x 20, 70, 600= Rs 61, 08, 270 or say= Rs 61, 08, 2000 /-

Total Annual Energy Saving = 1268.5 KVA + 20, 70, 600 units

Total Annual Energy Saving = Rs 17, 51, 000 + Rs 61, 08, 000= Rs 78, 59, 000 /-

Cost of Investment = “ NIL ’’

The average recorded demand - 2552.0 KVAThe KVA reduction, recommended - 1268.5 KVA

-------------------The KVA utilization & recording will be - 1283.5 KVA

-------------------This is well within the Sanctioned and Contract Demand with MPSEB = 1684 KVA

with a cushion of 400.5 KVA to accommodate any emergency or additional requirement.

Now the Municipality pays penalty for exceeding the Contract Demand of 1684 KVAunnecessarily. By the above arrangement, the Contract Demand of 1684 KVA can becontained. Hence paying penalty for exceeding the Contract Demand will be a saving to theMunicipality. After implementing the proposed Schedule, the MD is restricted to 1684 KVAwhich is the Contract Demand.

Energy Saving by avoiding excess consumption over Contract Demand :

Penalty paid by Sagar Municipality in respect of Raj Ghat

Water Supply Project at Sagar, Loc. Code : 1554500Cons. Code : 600035

Bill for January 2009

Recorded Demand - 2552 KVAContract Demand - 1684 KVAExcess over CD - 868 KVA

Present Energy Consumption:

Per Month Charges for Contract Demand 1684 KVA = Rs. 115 x 1684

= Rs. 1, 93, 660 /-

Per Month Penalty for excess over CD = (115 x 1.5 x 253) + (115 x 2 x 615)

= Rs. 1, 85, 093 /-

Therefore Total Annual Charges for KVA Demand = (1, 93, 660 + 1, 85, 093) x 12

= Rs. 45, 45, 036 /-

Energy Consumption per Year = 76, 15, 200 Units.

Charges for the Energy Consumption = Rs. 2.95 x 76, 15, 200

= Rs. 2, 24, 64, 840 /-

Total Electricity bill for one year = Rs. 2, 70, 09, 876 /- or say

= Rs. 2, 70, 10, 000 /-

After Municipality Energy Conservation schedule Maximum demand will be within 1684

KVA (Contract Demand). At Rajghat Raw water PH Only one pump of 170 KW is going to run for

17 Hrs / Day for 365 days in a year.

Similarly one pump of 845 KW is going to run at Water treatment plant for 17 Hrs

for 365 days.

Now, Current Annual Energy Consumption = (170 x 17 x 365) +(845 x 17 x 365) Units

= 10, 54, 850 + 52, 43, 225

= 62, 98, 075 Units / Year

Electricity bill for 1 year = MD Charges + Energy Consumption

= (1684 x Rs. 115x 12) +

(Rs. 2.95 x 62, 98, 075)

= Rs. 23, 23, 920 + Rs. 1, 85, 79, 321

= Rs. 2, 09, 03, 24 /- or say

= Rs. 2, 09, 03, 000 /-

Saving in Energy = Rs.2, 70, 10, 000 – Rs. 2, 09, 03, 000

= Rs. 61, 07, 000 /-

IGEA on Transformer and Distribution Audit

Sagar Municipality have established 1 No. Power Substation 33 KV / 6.6 KV – 400 VSubstation and availed 1 No. HT service connection from Utility M/s M.P.Poorv KshetraVidyut Vitaran Co. Ltd. Loc. code : 1554500, Cons. code : 600035 and S/C No. 0000000.

The details of Transformers connected are :

2 Nos. x 33 / 6.6 KV - Capacity of 3150 KVA = 6, 300 KVA

1 No. x 33 / 400 V - Capacity of 500 KVA = 500 KVA

Total Transformer Capacity = 6, 800 KVA

Sanctioned / Contract Demand - 1684 KVA

Load Factor of Station based on Transformer Capacity = 6, 34, 600 KVA

6, 800 x 0.9 x 24 x 31

= 6, 34, 600

45, 53, 280

The Load Factor - Utilization Capacity to the existing Capacity available ( TransformerCapacity ) is too less. This can be improved by providing 2 x 500 KVA 6.6 KVTransformer and 1 No. 500 KVA 400 V Transformer. By this the load losses can beavoided by achieving Energy Saving.

By providing the change in Transformer = 6, 34, 600

the Load Factor will become ( 2 x 1000 + 500 ) x 0.9 x24 x 31

Name of ULB : Sagar Municipality, Name of ESCO: EPIC Energy Ltd,Madhya Pradesh. Mumbai.

Period of Audit: 28.6.2009 to 09.07.2009.

IGEA on Street Lighting System

Sagar Municipality is serving the general public and road users of Sagar Town byoperating 34 No. Switch points through Timer switching control and MPEB Energy Metersto switch on / off the Street Lighting System and record energy used by Street Lights.

Existing System of Operation and Maintenance of Street Lights

The Municipality uses MPEB Service line poles for fixing Street Light Lamp fittings. There are no separate poles for the Municipality Street Lighting System.

The disadvantages of the existing arrangement of the Municipality

1. The design of the Street Lighting System as per BIS code to bring optimization inLux level and units consumption of electricity.

2. The down time of rectification of failure units is not in the hands of theMunicipality. Even if the Municipality is ready with spare units to replace thedefective ones, the Municipality have to depend on the MPEB to get shut - down andline clear, which makes more down time due to delay on MPEB side.

3. The earthing system also depends on the earth and maintenance on the part ofMPEB, which is not up to the mark. On measuring the leakage and Earth current,Earth current is found to be on the higher side bringing more losses due to poorearthing and leakage current due to unbalancing in the three phases and poorinsulation of Street Light Cables used by MPEB.

Hence the Municipality can plan for independent Street Light poles as per the design basedon BIS 1944 Part II Standards, which will give solution to the above defects bringing moreEnergy Efficiency, Energy Savings, more safety to the road users and general public, betterambience due to improvement in burning status and less down-time etc.

The Lamps used in the Street Lighting System are given below.

HPSV 180 W Lamps - 1059 No.

Metal Halide 300 W Lamps - 388 No.

Conventional 40 W TFL withMagnetic Choke - 2720 No.

GLS bulb 100 W - 859 No.

CFL – 36 W - 2 No.

CFL – 24 W - 31 No.--------------

Total : 5059 No.--------------

No. of Lamps Burning - 3761 No.

Burning Status - 74 %

Burning status of the Municipal lighting system shall increase from 74 % to 100 % byreducing the down-time of each type of failure by proper Planning and better coordinationwith MPEB by the Municipality.

Base Line Consumption

On review of Bills, it is noted that the energy meter in most of the switch points are foundto be defective and the MPEB adopts average billing. Hence, the Annual recorded / billedconsumption is not considered for fixing of the Base Line Consumption.

Base Line Consumption based on connected Load per Annum

= Circuit Watts / 1000 x No. of Bulbs x Operating Hours

= [ ( 180 / 1000 x 1059 x 3285 ) + ( 300 /1000 x 388 x 3285 ) +

( 53 / 1000 x 2720 x 3285 ) + ( 100 / 1000 x 859 x 3285 ) +

( 36 / 1000 x 2 x 3285 ) + ( 24 / 1000 x 31 x 3285 ) ]

= ( 190.6 + 116.4 + 144.2 + 85.9 + 0.07 + 0.7 ) x 3285

= 537.9 x 3285

= 17, 67, 002 Units.

Annual Base Line Consumption = 17, 67, 002 Units.

Annual Bill Payable = Rs. 3.20 x 17, 67, 002

= Rs. 56, 54, 406 /- or say

= Rs. 56, 54, 000 /-

Energy Efficiency and hence Energy Saving can be achieved in the Street Lighting Systemby

1. ( a ) Replacing the conventional HPSV – 150 W Lamps by EE - T5 120 W StreetLight Lamps.

( b ) Replacing the conventional 40 W Lamps by EE-T5 Lamps.

{The advantages can be seen from the comparison Table given in the Annexure.}

( c ) Replacing the Filament Lamps 100 W by CFL 36 W.

2. By providing control gears with GSM Technology for better control andMonitoring of Energy consumption, non – burning locations etc., in the CentralComputer at the Municipal office.

By installing Energy Saver with in-built MCCB, Stabilizer and Dimmer withthree selectable slots for fixing burning Hours of Street Lights

--with Voltage Reduction of 10 % during 07:30 pm to 12.00 pm;

--with Voltage Reduction of 20 % during 12.00 pm to 02.30 am;

--with Voltage Reduction of 30 % during 02.30 am to 05.30 / 06.30 am next day.

This brings 15 %, 30 % & 45 % Energy Savings in the Energy bills respectively. ForEnergy Saving calculations, minimum 10 %, 20 % & 30 % values of the three are slotsnoted above are adopted.

Current Consumption Calculations

KW reduction due to 1. (a, b & c ) and ( 2 ) above, in KW.

By1. (a, b & c ),

KW reduction = 537.9 – ( 60 / 1000 x 1059 ) + ( 25 / 1000 x 2720 )

– ( 36 / 1000 x 859 )

= 537.9 – ( 63.5 + 68 + 30.9 )

= 537.9 – 162.4

= 375.5 KW

By ( 2 ),

KW reduction = 0.10 x 375.5 for 4.5 Hrs. = 37.55 KW

= 0.20 x 375.5 for 2.0 Hrs. = 75.10 KW

= 0.30 x 375.5 for 2.5 Hrs. = 112.65 KW

Current Consumption = KW after reduction x Operating Hours.

= ( 337.95 x 4.5 x 365 ) + ( 300.4 x 2 x 365 ) +

( 262.85 x 2.5 x 365 )

= 5, 55, 083 + 2, 19, 292 + 2, 39, 850

= 10, 14, 225 Units.

Bill payable = Rs. 3.20 x 10, 14, 225

= Rs. 32, 45, 000 / -

Energy Saving = BLC – Current Consumption

= 17, 67, 002 – 10, 14, 225

= 7, 52, 777 Units.

In Rs. = 3.20 x 7, 52, 777

= Rs. 24, 09, 000 / -

Monetary Benefit is = Rs. 24, 09, 000 /-

Cost of Investment = Rs. ( 1025 x 2000 ) + ( 2640 x 500 ) +

( 859 x 100 ) + ( 34 x 12500 )

= Rs. 20, 50, 000 + 1, 32, 000 + 86, 000 + 4, 25, 000

= Rs. 26, 93, 000 /-

Cost Benefit Ratio = 26, 93, 000 / 24, 09, 000

= 1.12

Simple Pay Back Period = 1.12 x 12

= 13 Months.
