Cost of construction electricity per kilowatt-hour

Hello and a quick question to the forum community. Is it still the case that construction electricity costs about twice as much per kWh as "normal electricity"? So I mean, how much does it cost if a 33kW fan runs for about 60 hours? Surely around 1000 euros or so ^^

Thank you for the numerous replies :D
