Lee’s Landmarks – Emley Moor Station, Principality Stadium, Houses of Parliament

If you find that organising electrical jobs at your workplace can be hard work at times, imagine the challenges that those running major landmarks have to face. Here, we look at some of the awe-inspiring stats of three familiar landmarks.

Emley Moor Station

The tallest self-supporting structure in the UK, the concrete tower, locally known as the Emley Moor Mast,
was completed in 1971 and awarded Grade II Listed status in 2002.

The landmark tower replaced a cylindrical mast that collapsed under the weight of ice in 1969.

Only a few people outside those who work there have been allowed to ascend to the top; they include cricketer Freddie Flintoff and actor Robbie Coltrane.

Essential stats:

Height of tower: 330.5m (1,083ft)
Weight of tower: 11,200 tonnes
Primary transmission range: approx 40 miles
Time to ascend the mast by lift: around seven minutes

Electric facts:

Sixth most powerful transmitter in the UK
The main UHF transmitter site for a large part of the Yorkshire region
Has 56 small repeaters across the region to improve its signal coverage
The key operations base for the broadcast division of Arqiva, responsible for monitoring the whole of the UK broadcast transmitter network
Number of lightening strikes to hit the tower’s conductor during a July 2014 storm: approx 75

Principality Stadium, Cardiff

The home of Welsh rugby, Cardiff’s Millennium Stadium was renamed the Principality Stadium on 22 January 2016, representing a new deal between the Welsh Rugby Union and the Principality Building Society.

Originally built to host the 1999 Rugby World Cup, the stadium has a fully retractable roof. It has hosted a range of other sporting events, including football matches and speedway events, as well as major concerts with artists such as Madonna, The Rolling Stones and Take That.

Essential Stats:

Number of rugby matches held to date: 110
Biggest concert crowd: 73,354 for U2 in 2009
Number of bars: 27
Number of public food units: 27

Electric facts:

The new 40m-high Principality Stadium sign was switched on by Wales Head Coach Warren Gatland
Number of LED lighting units recently installed by UK energy group SSE: 2,500
Amount of savings expected from the new lighting system: around 70%
Increase in light levels with new system: previous level 60 lux, new level 100 lux

Houses of Parliament

The seat of government and one of London’s most important landmarks, the Palace of Westminster, commonly known as the Houses of Parliament, was originally built on the banks of the Thames in medieval times, although following several fires, most of today’s structure was built between 1840 and 1870.

A royal palace and former residence of kings, the building today is home to the House of Commons and the House of Lords. The most famous tower is the Elizabeth Tower, completed in 1859 and known as Big Ben after its great bell. The Great Clock was started on 31 May that year.

Essential Stats:

Number of rooms: almost 1,200
Number of staircases: 100
Tallest tower: Victoria Tower at 98.5m (325ft)
Number of steps to the clock room: 292
Weight of Big Ben’s bell: 13.8 tones
Length of minute hands on the four clocks: 4.2m (3ft 9”)

Electric facts:

Date electric lighting installed in House of Lords: 1883
Date electric lighting installed in House of Commons: 1912
Voltage Optimisation equipment has recently been installed to reduce energy wastage
A programme of LED lamp replacement and lighting controls is under way
Electrical supply to the estate has been sourced from renewable and good quality combined heat and power sources since April 2013

You Cannot Secure What You Cannot See: Building an OT Asset Inventory

A production line rarely arrives as one neat, self-contained system and stays that way. It acquires a replacement drive here, a new HMI there, a remote support connection added during an urgent breakdown, and perhaps a reporting link into the wider business network. Each change may be sensible on its own, yet over several years […]

BS 7671 Amendment 4: What Industrial Sites Need to Review Before October 2026

A change to the Wiring Regulations will not stop a production line on the day it is published. Its effects are usually felt more quietly: in a design decision, a procurement specification, a shutdown plan or a certificate that has to stand up to scrutiny months later. For industrial businesses, that makes the transition to […]

Power and Distribution: Ensuring Load Capacity Matches Modern Demands

Manufacturing sites have changed significantly over the last decade. Many factories are running more automated equipment, more digital systems, more efficient lighting, more sophisticated control panels and, in some cases, new electrical demands such as EV charging, battery storage or additional production lines. The issue is that not every site’s electrical infrastructure has changed at […]

Variable Speed Drives: Boosting Efficiency Without Sacrificing Performance

Energy reduction remains a major priority for UK manufacturers. Rising operating costs, pressure to reduce carbon emissions and the need to maintain competitiveness have all pushed factories to look more closely at how energy is being used across their sites. In many manufacturing environments, one of the best places to start is with motors. Motors […]

Electrical Documentation and Labelling for Safety and Traceability

In a busy manufacturing environment, electrical systems are often changed, extended and adapted over many years. New machines get installed, control panels get modified, production lines are relocated, additional lighting is added and distribution boards get upgraded. Over time, what began as a well-documented installation can become difficult to follow if records are not updated […]

What a Factory Acceptance Test (FAT) Should Include and Why It Matters

Installing new machinery, production equipment or automated systems into a factory is rarely a small decision. For most manufacturers, it involves significant capital investment, careful planning, disruption to normal operations and a clear expectation that the new equipment will improve output, efficiency, quality or safety. That is why a Factory Acceptance Test, often shortened to […]
