The main tasks are to ensure efficient operation and development of the national electricity and gas infrastructure as well as ensuring equal access for all users of the infrastructure.[2]
History
Energinet was created by a merger of power grid operators Eltra, Elkraft System and Elkraft Transmission, and by natural gas transmission system operator Gastra.[3] The merger took place on 24 August 2005 with retrospective effect from 1 January 2005.
Eltra owned the electricity transmission network west of the Great Belt and was system operator there.[4] It was owned by 44 network companies there. [5] To the east of the Great Belt there were two companies: the system operator Elkraft System and the transmission network company Elkraft Transmission.[4][6] They formed a joint organization and were owned by NESANET A/S [dk], KE Forsyningen, SEAS Transmission A/S [dk], NVE Net A/S [dk], Frederiksberg Elnet A/S, Hillerød Elforsyning, Helsingør Elforsyning, Roskilde Netvirksomhed, Nykøbing Sjællands El-Net and SK-Net A/S.[7]
Energinet operates the 400 kV electricity transmission grid[8] and the gas transmission grid.[9] The company owns and operates also 132 kV[10] and 150 kV power grids ("Regionale Net") and the HVDCGreat Belt Power Link, and it is a co-owner of the power interconnections with Sweden (Konti–Skan), Norway (Cross-Skagerrak) and Germany (Kontek).[11][12][13] A 700MW submarine power cable called COBRAcable to the Netherlands is planned with TenneT,[14][15] and a 1,400MW cable (Viking Link in 2022) to Britain is investigated with National Grid, expected to cost DKK 15 billion.[16][17] Cobra and Viking were put on the EU "Projects of Common Interest" list in November 2015, along with the Krieger offshore wind turbine cable to Germany.[18] Of the high voltage power lines on land, 25% were laid as underground cables in 2014.[19]
