The company's operations span an area of 510 sq. km. with a recorded peak load of around 2074 MW. It is the only distribution utility to receive the ISO 9001, ISO 14001 and OHSAS 18001 certification, and the only Indian utility to have SA8000 certification.

The company's distribution automation project is based on systems such as GIS (Geographical Information System), ADMS (Advanced Distribution Management System) and OT's (Operation Technologies).

The ADMS controlled and unmanned grid stations, GSM based Street Lighting System, SMS based Fault Management System and Automatic Meter Reading employed by the company are all firsts in the capital city area. Modern technologies such as High Voltage Distribution (HVDS) System and LT Arial Bunch Conductor are also being used by them to curb power theft in the region. Tata Power Delhi Distribution Ltd is the first Indian utility to develop and set up Geographical Information System which has seamless integration with SCADA, SAP-ISU and Fixed Asset register. This system has unique mechanism of asset management, complaint management, network planning, etc.

Tata Power Delhi Distribution Ltd. is documented as the first in the country to initiate an Automated Metering Infrastructure based Auto Demand Response programme to help manage grid stress and peak demand.[3] This is part of the company's Smart Grid Journey

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 Limited [4]

In 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 (Transfer Scheme) Rules, 2001.[5] The Delhi Vidyut Board was unbundled and split into six entities managed by BSES Limited (now Reliance Infrastructure) 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 (known today as Tata Power Delhi Distribution Limited).[6][7]

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 (AT&C) losses of the firm by 17% in the next five years [7]

On 1 July 2002, Tata Power Delhi Distribution Limited began its operations as the North Northwest Delhi Distribution Company [8]

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 (AT&C) losses were being recorded, made considerably worse by rampant power theft, faulty meters and open overhead networks.[9][10]
  • The electricity supply system in the North and Northwest Delhi distribution area was extremely unreliable due to inadequate network planning and infrastructure.[9]
  • No IT interface or consumer services existed. Inherited only 2 computers that too in non-functional conditions.[10]
  • There was no system of consumer services, a backlog of 1,00,000 complaints when it took over [10]
  • 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.[10]
  • Energy companies have a new weapon to tackle electricity theft.[11]

Shareholding

Tata Power Delhi Distribution Limited is owned by the Government of Delhi and Tata Power. A majority stake of 51% was acquired by Tata Power in 2002-03 post the unbundling of the Delhi Government owned Delhi Vidyut Board in the form of equity and preference shares. Since then it has paid a total dividend of Rs.367.41 crores on five occasions to its stakeholders – Tata Power and the Delhi Government. In mid-2008, the company issued bonus shares. In 2014, the Tata Power Delhi Distribution Limited paid a total of Rs.1285 crores as dividend to its shareholders.[12][13]

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 (DMS), Distribution Automation (DA) and SAP components including Outage Management System (OMS) were implemented in the following years [14]

By 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 [15]

In 2014, the company became the first Indian power utility to launch an Automated Demand Response (ADR) Project with smart meters in the capital. This Rs. 12.5 crore pilot project [15] 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 (Advanced Metering Infrastructure for Smart Meters) were conceptualised together. The project was rolled out with approval from the Delhi Electricity Regulatory Commission (DERC)[16]

Apart from ADR infrastructure, the projects components include Smart Meters,[17] Radio Frequency (RF) Mesh Based Communication, Meter Data Management System (MDMS) and integration with other previously existing operational technology and IT systems like OMS and SAP.[16] 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.[18] 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 [16]

Tata Power Delhi Distribution Limited was hailed for its initiatives in smart grid technologies at the International Conference & Exhibition on Smart Grids and Smart Cities organised by India Smart Grid Forum 2015 (ISGF) in March, 2015 [19]
