A rare chance to see energy in action! Hidden behind two Listed Building façades opposite Smithfield Market, and spread across eight floors below and above ground, E.ON’s Citigen energy centre produces electricity, heat and cooling to buildings across the Square Mile.
Citigen is the hub of a low carbon decentralised energy network – covering 11km of pipes snaking through the City – and providing the heating and cooling equivalent to 13,600 average homes to business and residential properties from the Guildhall to the Barbican Centre.
E.ON is commissioning a 4MW heat pump at Citigen, connected to three boreholes which tap the natural heat of the Earth from 200m under London. This new technology will reduce overall carbon emissions by 30% and support the City of London’s ambitious environmental plans.
