Eldvörp

HS Orka is preparing the utilization of geothermal energy in Eldvörp in Grindavík. The project involves, on the one hand, connecting Eldvörp to the Svartsengi power plant and, on the other hand, drilling new high‑temperature wells for reinjection in a suitable area intended to support future geothermal utilization in both the Eldvörp and Svartsengi areas.

In the utilization category of the Master Plan

Eldvörp has been under consideration by HS Orka for a long time. The area contains a borehole drilled in 1983, which has been used for measurements and monitoring. A newer drilling pad, prepared in 2019, is also in place.

Eldvörp is classified in the energy‑utilization category of the national Master Plan, which allows for up to 50 MW of development.
In the environmental impact assessment process now being prepared, the possibility of increasing electricity production in Svartsengi by up to 25 MW — from 85 MW to 110 MW — is being examined.

Growing demand from the community

Demand for electricity and hot water in the Suðurnes region has increased rapidly, and the current production capacity in Svartsengi is approaching its limits. Utilizing geothermal energy in Eldvörp creates an opportunity to meet this growing demand in a cost‑effective and environmentally friendly way.

Research in the area has confirmed the connection between Eldvörp and Svartsengi. The geothermal system in Eldvörp is energy‑rich, and recent flow tests in an exploration well show promising results. The project will largely rely on infrastructure already in place at Svartsengi.

Energy from Eldvörp processed at the Svartsengi power plant

Based on a site‑selection analysis carried out in earlier stages of the project in cooperation with HS Orka, the municipality of Grindavík, and the Blue Lagoon, it has been decided to connect the Eldvörp development to the Svartsengi power plant. This option has been, and continues to be, considered both economically feasible and environmentally favorable.

To support continued and future operations, the current reinjection area at Svartsengi is planned to be relocated to a more suitable site, where new reinjection wells will be drilled. This solution improves operational conditions in Svartsengi, increases the security of production, and creates room for further development of geothermal utilization in Eldvörp.

Geothermal production in Eldvörp and the new reinjection area is expected to be operational by mid‑2029.
