UK Power Networks has partnered with Barhale to build a micro-tunnel under the Grand Union Canal in West London for the HS2 Euston line
The new micro-tunnel will be used to carry power cables for HS2’s Tunnel Boring Machines (TBMs).
Three new high-voltage cable circuits, around 3km in length, will be energised to the Distribution Network Operator’s nearby substation, which feeds into the network that will power the manned TBMs.
Barhale has been appointed to drive a 125m-long tunnel beneath the Grand Union Canal, reaching the company’s substation on Atlas Road.
The tunnel was constructed from pipe-jacked, pre-cast concrete sections
The completion of the micro-tunnel for the HS2 Euston Line will allow the final section of the 33,000-volt cable route to be completed.
Works are expected to be completed in spring 2024.
Pamela Ali, programme manager of Capital Programme at UK Power Networks, said: “It has been a huge achievement to successfully and safely construct the micro-tunnel which will enable us to install our circuits across the Grand Union Canal. A huge thank you to the HS2 and the Canal & River Trust for their support throughout.”
A ‘key piece’ in the HS2 jigsaw
Niki French, head of utilities, HS2, added: “The delivery of this power tunnel is a critical part of our programme to build the new high-speed railway into the heart of London. Through close collaboration and great teamwork, we have worked together to ensure the HS2 programme is maintained. It has been a pleasure working with the dedicated UK Power Networks team, who are always professional, helpful, and genuinely do care.”
Barhale’s regional manager Ovi Frunza said: “This microtunnelling project is another key piece in the HS2 jigsaw.
“We are pleased to be able to continue to play our part in the continuing construction of HS2. We are involved in works at several sites along the route, including essential diversionary work at Ruislip and enabling works at the London terminus.”
