UK’s Largest Hybrid Generator

The construction of new passenger tunnels between existing platforms at Kennington Station had to be completed within a 16-week window and works were required 24/7. There was insufficient power supply available from the station and therefore a large external diesel generator was required.

The generator had to be located very near to residential properties and there was concern over the noise and air quality impacts this would have. FLO worked with Power Electrics and Off Grid Energy to use gridtogo™, the UK’s largest temporary hybrid generator system.

During the day, the unit ran off the diesel engine to supply power for the works, whilst also charging the battery unit. This meant that the unit could be programmed to switch over to the battery unit to provide near silent and emission-free power between 10pm and 8am each night. Without this the project would have likely needed to have re-housed the local residents for the 16 weeks due to the noise levels.

Over the course of the 16 weeks the use of the hybrid generator avoided around 66,000 litres of fuel consumption. This equates to a saving of approximately 156 tonnes of carbon emissions which is approximately the same as 56 flights from London to Sydney.

Other benefits include:

• Reduction in the amount of harmful emissions such as particulate matter and nitrogen oxides (NOx) associated with combustion of diesel fuel.
• Reduction in noise emissions.
• Reduction in carbon emissions.
• Reduction in fuel costs.
