It will connect Berkshire and Essex. Not an easy task to take on, as you can imagine. Which is why BAM, Ferrovial & Kier (BFK) have teamed up to bring together their strengths in tunnelling, civil engineering, and construction.
This presented Energyst with big challenges regarding safety, health and logistics. As Energyst’s Sales Manager Alex Thomas puts it: “UK rail company Crossrail had raised the standards of safety and environmental impact in London, stating diesel particulates and NOx given off by all diesel machinery must be kept to a minimum.
All generators on the project had to be modified to comply with the new health and safety regulations.” On a logistics level, there was another challenge Energyst had to take on: how to move four 250kVA generators up and down the tunnel as work progressed. And of course, working underground does not make things easier for the on-going servicing of the generators. Without a telephone signal, the lines of communication are limited.

The trolleys were constructed locally, strong enough to hold the generators, and set up so they could be pulled up and down from each end of the tunnel to where they were needed. Three of the trolleys have already been put to work. Borrowing on the tunnelling tradition of assigning girls’ names to drills, the trolleys too were christened: Milly, Tilly, and Lily.
To meet increasingly stringent health, safety, and sustainability regulations, all of the generator sets were retrospectively fitted with diesel particulate filters, to reduce emissions. Again, the work was carried out on location, inside the tunnel, to save time and keep within tight deadlines.
A power solution that would function as the mains supply for six months. Why it had to be custom-made? Due to space limitations on the surface. these generators had to be placed 35 metres below ground, operated with a remote fuel system to reduce the risk of large quantities of fuel underground, and to limit the environmental impact. These machines operate on a ‘load on demand’ basis, enabling the customer to vary loading according to actual demand.
That’s why Energyst engaged intensively with BKF to first understand their precise requirements, to help them stay ahead of the game, where safety and emissions regulations are concerned.
