Developing a Successful Energy Efficiency Program in Municipal Sector Pradeep Kumar Sr. Technical Specialist Mission Statement: The Alliance to Save Energy promotes energy efficiency worldwide to achieve a healthier economy, a cleaner environment, and greater energy security. What is the Alliance to Save Energy? Established in 1977 Non-Profit A leader in energy efficiency in all relevant sectors: • buildings • industry • municipal • utilities • appliances • transportation • research • policy • education • federal government (e.g., FEMP) Experience in over 30 countries Recognized as the municipal water and energy efficiency expert in India Developing a Municipal Energy Efficiency Project What Can Municipalities Do To Promote Energy Efficiency? Create management infrastructure Expand water metering and monitoring systems Develop baselines and metrics Carry out facility assessments Establish goals and benchmark success Develop an action plan Seek outside assistance Mobilize community action Management and leadership are key What Municipalities will get More Water & Better Services delivered to Consumers Saves Money / Better Value for Money Spent Saves Energy / Extra Energy for other usages Opportunity for Savings: 15 – 40% of annual energy cost 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 are the reasons for undertaking the EE project? Rising energy prices Increased water demand What are the goals for the project? Reduce energy costs Improve delivery of services Reduce GHG emission Is the project feasible? Market analysis , Technical analysis, Financial analysis GUIDELINES FOR SELF-ASSESSMENT What type of contract should be used for the project and how should it be financed? Turnkey – Municipality Self financing (O&M funds, Other ) Municipality borrows from private financial institution Energy Services – ESCO financing Performance Contacts Guaranteed savings or Shared Savings Indicative Bid Evaluation Criterion Accreditation/Certification by BEE and/or PCRA or SDA No. of Certified Energy Auditors with the firm Municipal Energy Efficiency Experience Similar Project Experience Measuring instruments available Annual turnover during the past 3-5 years Qualification Firm Credibility Performance contracting experience – In case of ESCO implementation Successful client list Focus Area Water Supply – Bulk water & distribution Sewage handling systems Street Lighting Buildings 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 Case Studies Energy Saving Potential in Four Towns in Karnataka Type of Proposal Nos.
