The wholesale market
Landsvirkjun does not sell its energy directly to homes or small businesses. Landsvirkjun sells electricity on the wholesale market to suppliers who then sell the electricity to end users. These suppliers buy some of their electricity from Landsvirkjun but also generate part of their supply at their own power stations. Approximately 2.1 TWh or 15% is sold in this manner.
The suppliers include Orkusalan, ON Power, HS Orka, Fallorka, Westfjord Power Company, Rafveita Reyðarfjarðar and Íslensk orkumiðlun.
A new type of wholesale contract was introduced in 2017 to replace contracts that had been valid since 2005. The new contracts were designed to improve the utilisation of the resource. Suppliers are no longer bound to purchasing energy for certain periods and short-term purchases have increased.
Short-term sales increased by a factor of four compared to previous years as a result of these changes and power savings were anything up to 70 MW in individual months. Average prices to the wholesale market fell between 2016 and 2017 as a result of more efficient purchases and reduced energy purchase commitments.
