“In 1989 Hong Kong Electric pioneered the introduction of mechanised tunnelling to Hong Kong, accepting the only bid that proposed the use of a tunnel boring machine for the construction of a 5.7 kilometre, 5 metre diameter cable tunnel as part of its transmission network, thus heralding a new era in tunnelling work in the city.

Routing cables through tunnels removes the visual impact of overhead transmission lines. For the same reason, the company is phasing out 66kV overhead cable circuits still present in the southern  part of Hong Kong Island. Electricity is now principally transmitted via a network of underground cables, which remove the problem of intrusion while offering the advantage of superior reliability, as they are protected against inclement weather.” (1)
