Tata Power Delhi Distribution Limited (TPDDL) is an Indian public–private utility company engaged in the distribution of electricity in parts of the National Capital Territory of Delhi. It is a joint venture between Tata Power Company Limited and the Government of the National Capital Territory of Delhi, and serves consumers across the north and north-west areas of the city. The company was formed as part of the unbundling and privatisation of the erstwhile Delhi Vidyut Board (DVB) in 2002.

Until 2002, electricity supply in Delhi was managed by the state-owned Delhi Vidyut Board. Persistent issues including high aggregate technical and commercial (AT&C) losses, ageing infrastructure and poor billing efficiency led the Government of Delhi to restructure the sector. The reform separated generation, transmission and distribution functions, and brought in private partners to operate the distribution business under a regulated framework supervised by the Delhi Electricity Regulatory Commission.
As part of this reform, three distribution companies were created. The licence for the north and north-west circle was awarded to a joint venture led by Tata Power, with the Delhi Government retaining a minority stake.
TPDDL distributes electricity to residential, commercial, industrial and institutional consumers in its licensed area, which includes neighbourhoods such as Civil Lines, Rohini, Pitampura, Badli, Narela, Bawana, Shalimar Bagh, Model Town and surrounding localities. The company operates a network of grid stations, distribution transformers and low-tension lines, and procures power through long-term and short-term contracts subject to approval by the regulator.
Tariffs, power purchase costs and capital expenditure are determined under multi-year tariff orders issued by the Delhi Electricity Regulatory Commission. The company has invested in supervisory control and data acquisition (SCADA) systems, geographic information systems (GIS), automated metering infrastructure and consumer-facing digital services.
TPDDL is frequently cited in Indian power-sector literature as a reference case for distribution reform. The privatisation model adopted in Delhi in 2002 has been studied for its effect on AT&C loss reduction, billing and collection efficiency, and consumer service standards in an urban Indian context. Along with the BSES distribution companies, it forms part of the framework that supplies electricity to the bulk of Delhi's population.
