The Shanan Power House is the reason Joginder Nagar exists at all. Commissioned in the 1920s and inaugurated in 1932, it captures the waters of the Uhl river — diverted from Barot through a long tunnel and brought down by a sequence of penstocks dropping more than 500 metres — and converts that fall into electricity that has been lighting up swathes of northern India for nearly a century.
The plant itself isn't open for casual tourism, but the engineering works are visible from the road and from the railway line, and the funicular trolley that historically carried materials up and down the steep slope is a curiosity for anyone interested in early 20th-century industrial archaeology. The hillside cuttings and the colonial-era housing of the original workforce still survive.
