Three main power supply (MPS) systems for the Dubai Metro are now located in Jebel Ali, a report said.
The Rail Agency announced that these substations will provide power to the Metro's Red and Green lines, the Gulf News report said
Out of the three MPS stations, MPS1 at Jebel Ali is due for completion in November for test track operations.
MPS2 and 3 are located at Union Square and will be ready in April 2008 to power the Red and Green Line networks.
Adnan Al Hammadi, director of Rail Construction, said the Dubai Metro uses the concept of braking to regenerate power and help minimise power consumption from the Dewa grid.
The Rail electricity system is based on the 750 volt direct current (DC) third rail technology.
