London, United Kingdom - 2014
 
Status: Existing
Stakeholders: Panasonic and Solarcentury

Blackfriars Bridge is set to be the largest solar bridge in the world. The 4,400 solar modules atop the bridge will cover a substantial 6,000m2 when completed. The array will create a staggering 50% of the electricity needed for the day-to-day running of the new sustainably constructed Blackfriars railway station.
 
First Capital Connect, which runs Blackfriars, expects the panels to cut the stations' carbon emissions by an estimated 511 tonnes a year, further reducing the carbon footprint of its train routes to the south east of England.
 
The bridge is also fitted with sun pipes for natural lighting and systems to collect rain water.
