Since its 2012 Lighting Master Plan, Barcelona has been retrofitting its roughly 157,000 streetlights to LED and converting its 2,582 control panels to remote, tele-managed dimming. A €22M Comprehensive Maintenance Plan of 153 actions runs to 2028, targeting 50% LED coverage (from 35%) and 100% remotely managed panels; street lighting accounts for about a fifth of the city's electricity. In testbed districts such as 22@ and El Born, lampposts also carry environmental sensors (air quality, noise, temperature) and public Wi-Fi, feeding the city's open-source Sentilo network. The city's early projection put savings on dimmable LED lamps at roughly a third.
