Hydropower

Hydropower is a clean renewable energy source. Snow and rainfall, creating streams and rivers, renew the source.

Buying Energy Attribute Certificates (EACs) from hydropower guarantees that the renewable energy consumed is from this source.

Historically people have used rivers for agriculture and to power watermills and sawmills for example. Today, rivers are re-directed through hydro generators to produce electricity.

Hydropower categories

Reservoir production

Water is stored in reservoirs, with the flow controlled to produce an even supply. Pump storage plants pump water upstream during periods of low demand. The water is released when demand is increasing.

Run-of-River

It uses natural river flows, not reservoirs or water storage.

Small Scale Origin

Hydropower plants are those with less than 20 MW capacity.

Hydro numbers

A large share of the world’s power production comes from hydropower. In Norway, hydropower represents approximately 99% of the total electric power production. With 156 TWh of production in a normal year, this is the highest volume in Europe.

Norway has more than 100 years’ experience and world-class competence in building and operating hydropower plants. Over the past decades, older installations have been upgraded to increase operational efficiency. The operations are also designed to reduce the impact on the environment and help improve local biodiversity.

Hydropower generation in the Net Zero Scenario, 2015-2030

In 2022 global hydropower generation increased by almost 70 TWh (up close to 2%) to 4 300 TWh with a total capacity addition of 32 GW. Annual net capacity growth has slowed in recent years, due to fewer large projects being developed in China and Brazil. However, cumulative capacity is still expected to increase by an additional 230 GW by 2030 (IEA).
