It is really different, some people have variable pricing that changes monthly, and some have fixed pricing.

The cheapest fixed price I could find is $0.34 per kWh, on Elpristavlen[0] (lists of power prices)

DONG Energy[1] states a price of $0.27 per kWh.

Note that the price might not include power sources from renewable energy, and it excludes the subscription you pay to the power company.
