Contract for 62 km HV Transmission Line
Landsnet has contracted Mannvit for the design of two new 220 kV high voltage lines in North-East Iceland. The design was bid out in April 2015 and Mannvit won the bid with the most economical proposal. The HV line will connect the Theistareykir geothermal power plant to Landsnet‘s main grid as well as connecting the industrial area at Bakki in North Iceland to the grid.
PCC is building one of the world’s most advanced silicon metal production plants at Bakki. PCC’s production start-up capacity of 32,000 tpy is scheduled for 2018. The facility is to be powered exclusively with electricity generated from renewable sources. The plant will be fed by the two HV lines, named Kröflulína 4 and Theistareykjalína 1, which will be 62 km long. The construction will take two years and start of operation is scheduled in the fall of 2017.
„It particularly positive to have the opportunity to continue to support Landsnet’s build-up in Northern Iceland related to the industrial projects in Bakki and the strengthening of the grid as a whole”, said Mannvit‘s CEO, Sigurhjörtur Sigfússon Sigfússon at the signing of the contract with Landsnet’s CEO, Guðmudur Ingi Ásmundsson. The agreement with Landsnet states Mannvit will assist with the tower type selection, tower overview drawings, tower foundations and conductors. Furthermore, Mannvit will prepare tender documentation and project descriptions for all equipment and construction work. Procurement for track routing, earth works and foundation construction is scheduled to take place by year-end 2015 and all materials will be bid out by 1st quarter of 2016.
