Tata Power-DDL Solar Journey

About Tata Power-DDL

Tata Power-DDL has been the frontrunner in implementing power distribution reforms in the capital city and is acknowledged for its consumer friendly practices. Since privatization, the Aggregate Technical & Commercial (AT&C) losses in Tata Power-DDL areas have shown a record decline. AT&C loss is a measure of overall efficiency of the distribution business that is the difference between units input into the system and the units for which the payment is collected. Today, AT&C losses stand at 8.59%, which is an unprecedented reduction of around 84% from an opening loss level of 53% in July 2002.

Tata Power-DDL has to its credit several firsts in Delhi: SCADA controlled Grid Stations, Automatic Meter Reading, GSM based Street Lighting system, SMS based Fault Management System, etc. Tata Power-DDL has also embarked on its Smart Grid Journey and has become the first utility to initiate Automated Metering Infrastructure based Auto Demand Response program in the country which will help in managing peak demand & Grid stress.

Tata Power-DDL Approach

Study on Solar Project:

In 2014, Tata Power Delhi Distribution Limited (Tata Power-DDL) received a grant from the US Trade and Development Agency (USTDA) to complete a feasibility study titled “Business Models for Distributed Energy Resource Deployment”. Tata Power-DDL engaged Energy and Environmental Economics (E3), a recognized energy consulting agency based out of San Francisco to conduct the study.

Main objective of the study:

  • •   To develop the business case for Distributed Energy Resources (DER), with focus on rooftop solar
  • •   To identify the regulatory roadmap and implementation strategies for DER and solar
  • •   To assess the trade-offs between different solar policies (NEM and alternatives)
