Transcription

1 Ramesh Ramadurai Empower

2 Outline Background Rationale Dimensions Key Components Approach & Issues Challenges Road Ahead

3 Background District Cooling is a credible alternative to traditional systems Most preferred energy efficient and environment friendly cooling solution Many entrants/early operators relied on bulk metering Customers not used to pay separately for cooling services Inequitable cost allocation Growing emphasis on efficient use of energy resources

4 Rationale Energy accountability Monitor and manage energy usage Pay for usage Fair & equitable Eliminates cross subsidization Utilities cost management Reduces administrative efforts Metering System Reliable data for billing Flexible tariff structure Prevent revenue leakage Credit risk diversification Change customer behavior Improves customer satisfaction Operational efficiencies
