London Heritage Quarter supports Project SWAN, a low-carbon heat network in central London, in collaboration with AECOM and the Department for Energy Security and Net Zero. Through Business Improvement Districts and partnerships, the initiative aims to establish a sustainable energy network. Project SWAN utilises low carbon sources like the River Thames and TfL ventilation shafts, and is estimated to supply five hundred customer buildings from four to six energy centres. The borough-scale energy network would serve an area from Pimlico to Strand Aldwych, providing 402 Gwh of power.
