Editing Cyberjaya (section)

===Backup electrical supply===
The Cyberjaya planning guidelines strongly required two electrical connections from two separate substations. Diesel generators up to full load (except air conditioning load) were specified to be installed in all commercial buildings. The electricity grid connection was also organised to enable "power [[islanding]]" and supported by the [[Serdang Power Station]]. The electricity service standard is set at 99.99% availability with a maximum of 10 seconds interruption for office and commercial areas and maximum 15 minutes interruption for residential areas. These measures were dreamed up to provide Cyberjaya with a comparative advantage against other Multimedia Super Corridor areas. However, Tenaga Nasional has extended the same standard to all urban areas connected to the [[National Grid (Malaysia)|National Grid in Malaysia]].
