Singapore Power is embarking on a $2 billion project from end-2012 to 2018 to build two cross-island transmission cable tunnels 60 metres underground to meet future demand.

The deep tunnels will facilitate faster and more efficient maintenance and replacement of cables, thereby reducing the frequency of road-digging works and thus minimising inconvenience to the public in the long run.

Singapore Power chief executive Wong Kim Yin said: "With the city's rapid growth and the corresponding increase in power demand, we are challenged to sustain this level of reliability and cost-effectiveness in achieving this performance.

"The deep cable tunnels will form the backbone of Singapore's power supply, serving future generations effectively, securely and with minimum inconvenience. It will translate to improved standards of living and performance for our residential, industrial and commercial consumers."
