Sidrapong, a cultural heritage site.

The central government has granted a cultural heritage site status to it. Situated just 12 kilometers from Darjeeling Town, in the foothills of Arya Tea Estate in Darjeeling District, it occupies a prominent location. Initially constructed in the late 80s with a capacity of 2×65 kW, it underwent phased expansions to meet the growing demand for electricity, ultimately reaching a capacity of 1000 kW.

The machinery inside the station

In 1916, 19 years after its commission on 10 November 1897, it underwent a machinery replacement to enable a more efficient triple-phase transmission. This upgrade was necessary as the power station had reached the limit of its water supply.

This power station operates by utilizing the water brought in from three streams or Jhoras (Nepali for streams) known as Kotwali, Hospital, and Barbotia. To channel the water, they employ flumes constructed from 1.3 mm thick black metal sheets, as well as masonry duct and concrete lining.

In order to establish this power station back in the 80s, the Darjeeling Municipality Commissioners borrowed INR 1 Lakh from the government. The Maharaja of Burdwan owned the selected site for the construction of the power station.

Historical Significance and Challenges Faced in Establishing the Power Station

Recognizing the project’s public interest, the Maharaja willingly handed over his orchard to the municipality.  All the machinery and materials for the project were imported from Britain, and individuals had to manually transport them due to the lack of any other convenient means of transportation.


Until 1978, the Darjeeling Municipality supervised the power station from its establishment. However, on January 30 of the same year, the West Bengal State Board of Electricity took over the power station as they absorbed the Darjeeling Electric Supply Undertaking. The Sidrapong Power Station was close to reaching a century of providing electricity when a landslide in the 1980s inflicted severe damage upon the station.


The closure of the antique power station for nearly a decade resulted from this eventIn 1997, the power station underwent revival to celebrate its 100-year milestone, and it has since been recognized and acknowledged as a cultural heritage site. The restoration of Sidrapong had been an ardent desire of the Darjeeling natives.


The residents of Sidrapong, Risheehat, Arya, and Bloomfield established a committee in 2003 to revive the power station. Central government granted Rs. 8 crore to Gorkha Territorial Administration (GTA) in 2014 for renovating historic monument following residents’ initiative. Presently, out of the three installed turbines, only one unit is operational for electricity generation.
