The largest power plants, Lysebotn 2, Lysebotn 1, Tjodan, and Flørli, are located in Lysebotn and along the Lysefjord. All power plants have undergone upgrades, expansions, and new construction since their initial development.

The remaining facilities are located in Jæren and Ryfylke. Power generation from the Stavanger facilities dates back over 100 years.
 
The catchment area for all the facilities combined extends over an area of more than 750 square kilometers. The regulating facilities associated with the power plants consist of over 80 dams, kilometers of water tunnels, gates, and valves.

Lyse Kraft DA

The facilities in the Stavanger region are owned by the hydropower company Lyse Kraft DA. Hydro and Lyse have merged parts of hydropower production in southern Norway into a joint hydropower company, Lyse Kraft DA, which is Norway's third largest hydropower player.

The transaction was completed on December 31, 2020. You can read more about the hydropower agreement here.

Lyse Kraft DA has a normal annual power production capacity of 9.5 TWh, of which Hydro owns 25.6 per cent and Lyse 74.4 per cent. As part of the agreement, Hydro will remain the operator of the power operations in Røldal-Suldal and also take over the operatorship of Lyses' hitherto wholly owned hydropower plant. Lyse will be responsible for marketing activities and water disposal.

As a result of the agreement, Hydro is Norway's third largest operator of renewable power production, with a total production of 13.6 TWh in a normal year. Adjusted for ownership, Hydro's annual power production is 9.4 TWh in a normal year.
