Average power generation from photovoltaic panels in Oslo

In 2021, Norway set a new production record with a total power production of 157.1 TWh. In 2022, there was low levels of water inflow to the reservoirs, and the total power production was 146.1 TWh. Hydropower accounts for most of the Norwegian power supply, and the resource base for production depends on the precipitation in a given year.

In a normal year, the Norwegian power plants produce about 156 TWh. In 2021, Norway set a new production record with a total power production of 157.1 TWh. In 2022, there was low levels of water inflow to the reservoirs, and the total power production was 146.1 TWh.

Many power plants in Norway have storage reservoirs and production can therefore be adjusted within the constraints set by the licence and the watercourse itself. Wind and solar power are intermittent; electricity can only be generated when the energy is available.

There are 30 thermal power plants in Norway, with a total installed capacity of about 642 MW. The power balance expresses the relationship between production and consumption and indicates whether the Norwegian power system is a net exporter or importer in a particular year.

The market for PV in Norway is split between of grid-connected systems and PV to off-grid applications . The main driver for the grid-connected segment is high environmental goals set by property developers who want energy efficient buildings or operations to reduce the amount of energy from the grid.

In a normal year, the Norwegian hydropower plants produce 136.49 TWh, which is about 88% of Norway's total power production. Water inflow and installed capacity determine how much hydropower the Norwegian system can produce. Inflow varies considerably during the year and from one year to another.
