Yes, a lot of incentives. But another important point is that they make some sense, due to the pervasiveness of renewable hydroelectric power in Norway. Being an oil producing country, we could have gone the other way, and just subsidized gasoline prices instead.
This part of subsidies (free charging) has been getting less expensive for the budget too, at least in nominal terms. The price of hydro-power exported to neighboring Denmark has dropped by almost 50% since 2010, as Denmark ramped up its wind mills, albeit also with subsidies.
