Drilling work has finished at the Theistareykir geothermal power plant project in the North of Iceland and commissioning is to start on the first 45 MW unit in the coming weeks.

In a statement on its website, Icelandic engineering firm Mannvit announces that drilling activities at the Theistareykir geothermal project in the North of Iceland have been finished.

Tests on the first turbine unit installed are about to get started.  Sufficient power for the first unit with 45 MW geothermal power plant has been secured with the existing wells. Over the past two years, 10 wells have been drilled, one of them in the nearby Krafla geothermal are. There have been drilled a total number of 18 wells at Theistareykir.

Mannvit has handled hollow design and assisted in surveillance in the drilling. Mannvit, through its subsidiary Mannvit-Verkís, also deals with the design of connections to steam supply as part of the overall design of the power plant. The steam generator has been operational and is used for preparation of the startup of the first unit assembly.

Tests are about to start of the first unit

Construction of the 90 MW Theistareykir plant has been completed and work is being done on the installation of the two units.  Developers are Fuji Electric (turbine) and Balcke-Durr (cooling end). The installation of the first 45 MW unit is being completed and testing and commissioning is to start in September. Installation of the second unit has started and the machinery is already up. Work is done in the layout of equipment and equipment. The first unit is expected to be operational on 1 December 2017 and the second unit will be operational on 1 April 2018. When completed the plant will have an installed capacity of 90 MW.

The electricity generated will be fueling a new silicon plant by PCC at Bakki near Húsavík, together with the strengthening of electricity distribution in the northeastern corner of Iceland.

Mannvit supervises the installation of the unit assembly and support systems, along with technical assistance in the tests and driveway of the power plant through Mannvit-Verkís. Mannvit-Verkís had previously worked on the design of the plant and made tender documents.
