All CPWD electrical tenders (for Delhi and other zones using DSR) are based on DSR 2021 rates. Contractors must:

Reflecting India's commitment to climate goals, the DSR 2021 phased out legacy lighting systems (CFLs, T8/T5 fluorescent tubes) in favor of integrated . Rates for smart lighting controls, occupancy sensors, and dimming systems were comprehensively integrated. Focus on Halogen-Free Materials A defining feature of the 2021 revision is

The Delhi Schedule of Rates (DSR) is a comprehensive document that provides a standardized list of rates for various construction activities, including electrical works. The DSR Electrical 2021 is a revised edition, which incorporates updated rates for electrical materials, labor, and services. This document serves as a benchmark for estimating costs, evaluating tenders, and determining the financial viability of electrical projects undertaken by the CPWD.

The is a meticulously crafted document that balances technical standards, safety norms, and reasonable costing for its time (late 2020–early 2021). For government electrical projects tendered before March 2023, it remains the gold standard.
