Electrical infrastructure struggling to support increasing technology needs
Companies in busy urban areas are facing serious power supply problems that could restrict their IT expansion plans.

Experts say that rapid growth in computer use in cities is placing a strain on the UK's ageing electrical infrastructure.

Adding significant server capacity can be delayed for several months by problems securing sufficient power supply, while obtaining electricity for a major new data centre can involve hold-ups of months or even years.
