HS Orka is advancing preparations for geothermal utilisation at Eldvörp on the Reykjanes Peninsula, citing strong resource potential and phased development plans.
Icelandic geothermal power company HS Orka is conducting blowdown measurements on an existing borehole in the Eldvörp geothermal area in Iceland with the aim of utilizing the sector to augment power generation at the Svartsengi geothermal power plant.
The project aims to increase the production capacity of the Svartsengi power plant by up to 25 MW, from 85 to 110 MW. The geothermal utilization and new injection area are expected to be operational by mid-2029.
Project background and resource context
The Eldvörp geothermal area lies within the Svartsengi volcanic system and has been the subject of exploration and monitoring for several years. According to HS Orka, existing geological and geophysical data indicate high subsurface temperatures and favourable reservoir conditions for future utilisation.
Recent public communication from the company confirms that preparatory work is now focused on refining development concepts, environmental assessments, and alignment with regional energy planning.
Development approach and timing
HS Orka has stated that any utilisation of Eldvörp would be approached in stages. Initial activities focus on technical evaluation and permitting rather than immediate construction. The company emphasises that development decisions will depend on updated reservoir data, environmental considerations, and grid integration needs.
The company added that the Eldvörp area is protected under the Nature Conservation Act. Thus, there are no plans to build a power plant in the area. Instead, pipelines will be built to connect the three existing wells to the Svartsengi power plant.
Icelandic media have highlighted that the area represents one of the more substantial undeveloped high-temperature geothermal zones in southwest Iceland. However, no firm timeline for power plant construction has been announced. We previously reported on the project.
Strategic importance for Reykjanes
The Reykjanes Peninsula hosts several operating geothermal facilities and remains a core region for Iceland’s geothermal power and heat production. Further development at Eldvörp could strengthen supply resilience in the region, particularly given increasing electricity demand from industry and infrastructure.
HS Orka has noted that geothermal utilisation in volcanic systems requires careful risk management, especially in areas affected by recent volcanic and seismic activity. Ongoing monitoring is therefore expected to remain a central element of the project.
