What Municipalities will get








Quick Paybacks
Can help reduce the need for new infrastructure
Carbon Credits- Contribution in reduction of GHG
emission
Steps for Developing a Municipal EE
Project





Self assessment to choose the best fit option for
undertaking Energy Efficiency (EE) program
Establishment of Energy management cell (EMC)
Collect energy usage data by carrying out a preliminary
(walk-through) audit
Develop and issue a request for Expressions of Interest
(EOI)
Issue a Request for Proposal (RFP)
Steps for Developing a Municipal EE
Project



Evaluate the proposals
Finalize consultant selection
Award the energy Audit or IGA contract,
In case of ESCO implementation :



Package the documentation for third party financing
Enter into the performance contract
Monitoring and Verification of savings (M&V)
GUIDELINES FOR SELF-ASSESSMENT
for UNDERTAKING EE PROJECTS



What is happening?
What is happening?

System might have under gone several changes
including addition of loads in delivery systems

Major retrofitting of pumps (in parts) might have taken
place

Changes in the station headers / piping arrangement

Look for minimum acceptable efficiency values for
pump/motor as part of tender??

Incorporation energy efficiency parameters during the
design stage it self??

Compare tenders not on ‘first cost’ but on ‘life cycle
cost’?
Reasons for poor efficiency – Water
pumping

Changes in system with the demand

Major retrofits of pumps and other system components –
change of BOP

Changes in operating practices/schedules

Less thrust for minimum acceptable efficiency values for
pump/motor as part of tender

Compare tenders on ‘first cost’ but not on ‘life cycle cost’
Reasons for poor efficiency- Street
lighting

No design based approach

Use of lighting components from secondary market

Inadequate metering and monitoring facilities

No proper guidelines on lamp/fitting selection

Absence of control systems

Selection of tenders on ‘Low cost’ basis for O & M of
street lighting
Remedies may involve











System redesign and retrofitting of equipment
Pump impeller reduction
Leak and loss reductions
Equipment upgrades
Low-friction pipe
Efficient pumps
Adjustable speed drive motors
Capacitors
Transformers
Maintenance and operation practices improvements
Water reclamation and reuse.
Energy Efficiency Recommendations
Include

Replacement of old pump with new pump (High
Efficiency)

Opting for suitable pumps (Matching of H & Q)

Rectification of pump to improve operating efficiency

Change of operating practises / better maintenance/
leakage

Scheduling of pumps operation and filling practice

Improvement in piping section / headers

In multiple pump operations, judiciously mix the
operation of pumps and avoid throttling

Have booster pump for few areas of higher head
EE Recommendations Include







Surrendering of Excess kVA demand
Enhancement of demand to avoid monthly demand
penalties
Power Factor improvement to avoid pf penalty &
reduction of demand
Switching off the transformers
Review of electricity tariff and opting suitable tariff
Segregation of electrical loads
Monitor all important system parameters like: motor kW,
pump head, flow temperature.
EE Recommendations– Street lighting







Use of energy efficient lighting
Design based approach
Regulating power parameters to suit the actual
requirements
Providing guidelines on usage of quality material
Controlling the burning hours of the lamps
Dimming
Staggered operation
No Cost /Low Cost EE Measures






Surrendering of Excess Contract Demand ( KVA)
Improvement of Power factor (PF) ( 0.95)
Improvement in O & M Practices
Separation of LT & HT Load
Minor Rectification in Pump
Leak Detection and Repair
Medium Cost Investment EE Measures

Installation of Capacitors – PF improvement

Replacement of Low efficient Pump set

Improvement in Piping – Suction & Header

Installation of Energy Efficient Motors

Enhancement of Contract Demand- Incase of shortfall
