Our Solar Journey

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.The AT&C loss is a measure of the 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.

With an objective to promote renewable energy, with special focus on Solar Rooftop solutions in India, Tata Power-DDL has undertaken a number of initiatives and has made its presence felt in the industry, as outlined below.

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.

The main objectives of the study:

The purpose of this study was to support Tata Power Delhi Distribution Limited in identifying and implementing various distributed energy resources such as Rooftop Solar PV, demand response & storage options to:

• Develop business case for DER with emphasis on rooftop solar PV
• Improve network reinforcement, reliability, environmental sustainability
• Increase renewable and green energy footprint
• Identify resources other than coal to offset peak load
• Develop regulatory roadmap for rooftop solar PV

In its endeavour to make Solar rooftop solutions in Delhi, India a success, Tata Power-DDL offers its services to its consumers for Rooftop Solar Project implementation. The Hon’ble Commission has accepted Tata Power-DDL proposal and has approved its proposed initiatives in Solar Projects which will ensure standardization and uniform compliance with stipulated Regulations as well as quality and safety norms.

Tata Power-DDL received the highest honour rating of SP IA (pronounced as solar power one A) as a "System Integration Grading for Solar PV projects" from ICRA, which indicates 'highest performance capability' & 'highest financial strength' of Tata Power-DDL to undertake solar PV projects. Tata Power-DDL is the only utility channel partner of MNRE with highest grading SP1A.
