Yeah we have started taking it seriously finally at work. I've been banging on for years that our base load at weekends is 2000kw/h, yes you read that correctly 2000kw per hour. Week it peaks about 4000kw/h when in fully production, could be slightly higher now we added some more processes and a couple of new buildings (circa 10,000 sqm)
Its a large industrial site, with lots of lighting, and lots of air extracting and air handling.
To give you can idea of the idiocy i have been fighting against. The old warehouse used to have about 30 500w lights (about 60 feet up in the air), when they broke I insisted (Ie refused to sign off the expenditure) that they were LED.
The electricians were all against it for some reason. I eventually won but at one point they were refusing to fit them, I said I would instruct external which triggers them massively!
That same warehouse has no light switch, I mean at all, those lights have no way of being turned off. The only way is to access the locked control room and flip the trip. Imagine if they were still the old 500w jobbies up there burning away, when 1/3 of the week technically is supposed to be no one there. (24/5 site)
Good news is we have finally busted the hurdle of solar, we are likely to be getting into something like 1-2MW of panels next year. We have acres of unused land so makes loads of sense.
