As a multi-billion pound business with eye-watering £86 million player transfers and £5.5 billion TV rights deals, it is easy to forget about the more mundane business energy prices associated with running a Premier League football club – such as lighting the pitch.
The Premier League handbook is strict on the lighting levels required stating a stadium’s floodlights must produce at least 500 lux at any location on a 120m x 90m pitch to meet the demands of evening matches, television broadcasters, players and spectators.
According to Thorn Lighting People, four 25-metre columns with a total of 48 lamps, each shining at 2kW, should provide the Premier League with a lighting standard.
Each column has a combined power of 96kW. If they’re on for 3.5 hours per match, they will use 1,344kWh energy.
Stadium floodlights have the equivalent power of 5,485 standard 0.07kW tube lights in an office.
If a small office uses tube lights with a total power of 1.26kW, the floodlights will use the same business energy as 18 left on for 44 days straight.
If the floodlights were on for 8 hours straight, it is the equivalent to the same office lights being on for around 128 days.
One club’s floodlight power during a match could:
Boil a 2kW kettle for a month
Chill food in a 3kW catering refrigerator for 18 days
Power a 3.5kW photocopier non-stop for 16 days
Imagine what could be done with a whopping 510,720kWh of power used by all clubs across 380 matches in the season – for example, it takes 20,000 million joules (5,555kWh) to make and build a car. Therefore the Premier League’s combined floodlight energy for a season could produce 92 cars!
Electricity costs 15.32p per kWh, so the cost of lighting one football match is £205. Over a season a club will play 19 home games and use 25,536kWh energy in floodlights at a cost of £3,912. With over 380 matches across the entire league, this price balloons to a massive £78,242.
