How much power does a streetlight consume per hour .

Depends on its wattage
They range from 70W, 125W, 250W, 400W

Streetlights in our area are burning 24/7 trying to calculate how much electricity is wasted seeing we have a power crisis in the country .

Take one out and measure it.

A standard sodium vapour street light is 250W.

The City of Cape Town is replacing their sodium vapour lamps with LED's which draw a lot less power.

Oh FFS! Eskom is the cause for the crisis, not street lights.

FFS your missing the point, the more electricity unnecessarily wasted the higher the risk of load shedding hence the question i posed to configure how much power is wasted through a few hundred streetlights burning 24/7.

A few years ago Eskom came around and replaced many millions of incandescent light bulbs with energy efficient ones. We still had load shedding in 2018, so clearly that didn't fix the problem, and there are limits to what demand-management can achieve. A few hundered street lights on 24/7 is the least of our problems.

Still a waste of resources......

OP did you report it to the municipality?

Eskom used to say they leave them on to prevent cable theft.

Not sure if that still applies.

The 24/7 doesn’t matter as electricity cannot be stored.

It’s rather whether they remain on during load shedding heavy periods.

Well I think it does as producing electricity is damaging to the environment and costs money and Eskom is a SEO.

If Eskom need money, who do you think they'll need to bail them out? Us the taxpayers. :|

Also Eskom have "issues" managing their coal supplies and maintenance of their infrastructure. So the more power you generate from the infrastructure (distribution and generation side), the more frequently you need to do maintenance.

Erm, they vary between 70W or 250W or 400W

Stteet lights staying on 24/7 are caused by two issues:
A) Photocell failure

The street lights are kept on to try and prevent cable theft. Live wires are more difficult and dangerous to steal than passive wires

They will produce the same amount of capacity regardless...

So it will have no effect.

Most suburban street lights are 250W.

I have yet to see a 70W street light, and I doubt they exist.

Highway lights will obviously have more power.

Street lights are there for safety. They solution lies in Eskom sorting out their generation capacity - not in them switching off street lights.
