Svartsengi Geothermal Power Plant Expansion, Iceland

About the project

Rafal played a key role in the installation of the new SVA7 unit at the Svartsengi geothermal power plant in Iceland — delivering critical electrical infrastructure for one of the country’s largest energy projects.

The project includes a 55 MW turbine installation – the largest of its kind in Iceland – along with major upgrades to the site’s electrical and hot water systems.
Rafal was one of three main contractors involved, responsible for key elements of the electrical installation.
Despite challenging conditions during construction, including multiple volcanic eruptions in the area, the project was completed according to schedule.

Scope of work includes

  • Installation of a 55 MW turbine system
  • Energization of a 132 kV substation
  • Construction and integration of cooling infrastructure
  • Design, assembly, and installation of electrical panels
  • Installation of high voltage and power distribution systems

Client:              HS Orka

Location:          Svartsengi, Iceland

Project period: 2025-2026

„HS Orka worked with Rafal as the electrical contractor during the construction of Unit 7 at the Svartsengi Power Plant expansion project.

The scope of work included the design, procurement, installation, and commissioning of major electrical systems, including transformers, medium- and low-voltage switchgear, DC systems, busbar systems, control cabinets, power and control cabling, and associated electrical infrastructure.

Throughout the project, Rafal demonstrated a high level of professionalism, technical capability, and commitment to quality. Communication and cooperation with the contractor were excellent and proved especially valuable under the demanding conditions created by ongoing seismic activity in the Svartsengi area.

HS Orka was very satisfied with Rafal’s performance and their contribution to the successful delivery of the project.“
