Diesel Generator: Air Quality Impacts

Prior to the availability of mains power the site offices and welfare units had to be powered by a diesel generator. This generator was located adjacent to the offices/welfare and in conjunction with Kings College London air quality monitoring (particulates and black carbon) was undertaken. The monitoring station was located on the stairwell next to the canteen door (which was usually left open).

The results of the monitoring indicated that the levels of black carbon where incredibly high when the generator was running. The air quality in the canteen and offices would have been significantly impacted.

A Firefly hybrid power-pack unit (essentially a battery) had been installed, which charged from the generator and was able to provide base-load power. When the power switched over to this source there was (as expected) a noticeable improvement in air quality and noise levels.

The study highlighted the need to consider where generators are located and also try to use the highest emission standard possible. The results of this study directly influenced the FLO Tideway site to procure a Euro Stage IV emission standard generator to reduce the impact on air quality.

The Firefly hybrid power pack was shown to have demonstrable benefits in terms of air pollution and noise pollution, as well as reducing carbon emissions.
