Job Overview
London Underground's trains and infrastructure are powered by electricity drawn from the National Grid at several Bulk Supply Points across the capital. This power is manipulated and distributed by the London Underground Power & Electrical Department, which operates approximately 300 substations across 250 miles of track. In addition, electricity is distributed to over 1,600 individual premises, including 270 London Underground stations and more than 20 depot locations.
Power assets are extensive, expensive, and highly technical, and they must be maintained in optimal condition for the Underground to run smoothly and adhere to its schedule. The electrical infrastructure and services are diverse, encompassing over 100,000 light fittings, tens of thousands of critical and general power supplies, 500+ UPS units, and various other specialist electrical asset groups.
