> The grid owner charge a fix connection fee together with a per KWh fee. My guess is that both fees are regulated.
Your guess is correct, and it's the basic equivalent of net neutrality. In essence, European energy markets moved to net neutrality when they were liberated. Before, the local utility "owned" the customer, and in turn got to decide where to buy (and/or produce themselves) the energy they sold to the customer. Their monopoly power was restrained by being publicly owned, or by being required to keep prices close to those charged by publicly-owned utilities.
Energy is slightly different in that it is almost a true commodity, so people rarely cared ("almost", because some consumers have since chosen to pay more for renewables)
