Citigen Location: East London Operator: E.ON UK CHP Ltd Configuration: 2 X 12.5-MW 18V46GD engines CHP Fuel: natural gas, distillate Operation: 1991 E/G supplier: Wartsila Quick facts: Behind this listed facade on Charterhouse Street in the heart of the City of London is one of the first, large-scale urban CHP systems in the UK. The building has housed different power and heating facilities since 1893. Citigen serves numerous important London buildings including the historic Guildhall, the Barbican Arts Centre, the Guildhall School of Music and Drama, the Museum of London, and London Central Markets (Smithfield). The engines are equipped with twin ABB VTR 5644-42 turbochargers. The engine cooling system has high, medium and low temperature systems and includes a number of heat exchange components. A number of boiler plants provide back-up heat in winter months. During the summer, heat is used to generate chilled water at 5°C using 2 absorption chillers rated at around 5.5MW each. Alternatively, two screw compression chillers rated at around 550kW each can be used to supply low levels of chilled water demand.
