$245 million worth a tender have been publicly announced by the London’s transport authority for investments in renewable electricity. The purpose is to decarbonize the city’s 150 year-old underground railway network.

The bidding targets suppliers of solar and wind power able to contribute to London’s net zero carbon by 2030 through 100% renewable energy. The London transport authority is seeking a power purchase agreement for 150 to 200 gigawatt hours a year, equivalent to just over 10% of its electricity use in its 2020-21 financial year.
