Gas-powered generators for the Olympic village, London
A whole life costing approach was used in determining the appropriate type of temporary electricity generators to be used during construction of the Olympic village in London. The financial, social and environmental implications of the different options were assessed. As a result, gas-powered generators were selected.
Despite costing more to hire, gas-powered generators have significantly lower fuel costs than diesel generators. In addition, the reduction in lorries for fuel delivery helped reduce road nuisance and congestion.
Carbon emissions of the alternative technologies were also considered, with a monetary value attached to emissions based on the Department for Environment Food and Rural Affairs (Defra) published Shadow price of Carbon. Gas generators were estimated to produce 10,470 fewer tonnes of CO2 than the diesel generators – a 22% reduction. An overall economic cost saving of around £13 million (€16 million) was achieved.
