50 new energy storage power stations planned in Oslo

How many GW of hydropower does Norway have?

Norway presently has 32 GW installed capacity in the hydropower system and 85 TWh reservoir storage, providing 97 per cent of its own electricity supply. Studies have shown that it is possible to develop additional 20 GW of new capacity in the Norwegian hydropower without construction of additional reservoirs.

Is additional hydropower storage capacity a cost-effective alternative?

Additional hydropower storage capacity offers an alternative to expensive capacities for peak thermal power generation. Comparing cost of new gas-power plants located in Europe versus costs of additional pumped-storage in Norway shows that the latter option would be more cost-effective for the provision of peaking capacity.

What if new interconnectors are built between Norway and other European countries?

If new interconnectors are built between Norway and other European countries, Norwegian hydropower sites can store energy during periods in which variable renewable generation exceeds the total demand, and produce energy during periods during which continental European production fall short of demand.

Is hydropower a good energy storage option?

The work combines technological, environmental and social science. The HydroBalance Study has shown the value of energy storage from hydropower if compared to other options for storage such as natural gas and batteries.

Why is power supply intermittent in northern Europe?

The power system in Northern Europe is characterized by large shares of wind and solar. Hence, power supply may be intermittent during periods of low wind speeds or low radiation.

Why is the electricity supply at northern Senja a problem?

The additional load to the overhead power cables that are supplying the communities at northern Senja results in interruptions and short voltage drops, disrupting the electricity supply to the business community and inhabitants on Husøy and Senjahopen.
