Origins
Tata Power Delhi Distribution Limited was initially known as the North Northwest Delhi Distribution Company and subsequently renamed North Delhi Power Limited. In 2011, nine years after it first started operations, its name was changed once again to Tata Power Delhi Distribution LimitedIn June 2002, the distribution network of the erstwhile Delhi Vidyut Board was privatised as per the provisions of the Delhi Electricity Reform Act, 2000 and the Delhi Electricity Reform Rules, 2001. The Delhi Vidyut Board was unbundled and split into six entities managed by BSES Limited and Tata Power. These six companies were BSES Rajdhani Power Limited, BSES Yamuna Power Limited, Delhi Transco Limited, Indraprastha Power Generation Company Limited, Delhi Power Company Limited, and North Delhi Power Limited.
Under the agreement, Tata Power gained a 51% stake in the North and Northwest Delhi firm with a payment of Rs. 187 crores. It also agreed to reduce the Aggregate Technical and Commercial losses of the firm by 17% in the next five years
On 1 July 2002, Tata Power Delhi Distribution Limited began its operations as the North Northwest Delhi Distribution Company
Challenges
After it began its operations in 2002, Tata Power Delhi Distribution Limited was faced with four key problems:- More than 50% Aggregate Technical and Commercial losses were being recorded, made considerably worse by rampant power theft, faulty meters and open overhead networks.
- The electricity supply system in the North and Northwest Delhi distribution area was extremely unreliable due to inadequate network planning and infrastructure.
- No IT interface or consumer services existed. Inherited only 2 computers that too in non-functional conditions.
- There was no system of consumer services, a backlog of 1,00,000 complaints when it took over
- The 5400 employees of the erstwhile Delhi Vidyut Board who were absorbed into Tata Power Delhi Distribution Limited exhibited attitudinal and cultural issues. Their working conditions were far below Tata standards.
- Energy companies have a new weapon to tackle electricity theft.

Smart technology
In 2003, Tata Power Delhi Distribution Limited made its first ten-year technology roadmap. Different technologies such as SCADA, GIS, Distribution Management System, Distribution Automation and SAP components including Outage Management System were implemented in the following yearsBy 2008, TPDDL had achieved 100% consumer indexing using GIS in its area of business, the first step towards implementing its smart grid project. The second phase of the smart grid project was launched in October, 2013
In 2014, the company became the first Indian power utility to launch an Automated Demand Response Project with smart meters in the capital. This Rs. 12.5 crore pilot project was implemented in partnership with IBM, Honeywell, Landis+Gyr and with the participation of select Industrial and Commercial Consumers of Tata Power Delhi Distribution. It is one of the first projects in the world where ADR and AMI were conceptualised together. The project was rolled out with approval from the Delhi Electricity Regulatory Commission
Apart from ADR infrastructure, the projects components include Smart Meters, Radio Frequency Mesh Based Communication, Meter Data Management System and integration with other previously existing operational technology and IT systems like OMS and SAP. It covers over 100 km2. of Industrial & Commercial Belt in North and North-West Delhi and will help to analyse consumption patterns and optimise equipment performance. Up to 250 consumers are participating in the project, leading to a collective shed potential of 20 MW. Future plans include extending the project to include 800 additional consumers which would lead to a shed potential of another 20 MW
