The Svartsengi Power Station, built in 1976, was the first geothermal power plant for both district heating and power generation. Located in the south-west part of Iceland, it is a saline and volcanic geothermal site.

The Svartsengi site will be used both as an ORC demonstration site and a material testing site within MEET.

Iceland is situated on the Mid-Atlantic ridge, on the boundaries of the Eurasian and North American tectonic plates. Svartsengi is on the Reykjanes Peninsula, the youngest part of Iceland, on an active volcanic zone. The Svartsengi reservoir system is a seawater-recharged hydrothermal system. Over 30 wells have been drilled at the site. While most have a depth of 1.5-3 km the deepest well, IDDP-2 reaches a depth of 4.65 km.

The geothermal brine supply at Svartsengi Power Plant will be used to validate the output of the ORC system. The Svartsengi area is a high temperature area and thus not the main target customer for the MEET project. Testing in this area does nonetheless provide useful information for more demanding environments.
