EFLA is a general engineering and consulting company based in Iceland with international activities and consultancy around the globe. EFLA comprises highly qualified and experienced professionals operating in a wide variety of fields whose common goal is to provide clients with the highest possible level of services and solutions, no matter the nature or scope of the project involved.
With EFLA playing a key role from start-up to handover, the Nesjavellir Geothermal Power Plant brings green energy from deep underground direct to the residents of Iceland's capital.
The Nesjavellir Geothermal Power Plant, Iceland
For any country fortunate to enjoy access to it, geothermal power is probably the ultimate in renewable energy, and harnessing it a highly specialised branch of engineering. Decades of experience working at the cutting edge of this rapidly evolving technology have served to earn EFLA a leading role in such projects, a major example of which is the Nesjavellir Geothermal Power Plant, southwest Iceland, a facility operated by Reykjavík Energy which today produces 300 MW of 85°C hot water and 120 MW of electricity.
From planning to handover and on-going servicing of the power plant control system, EFLA played a leading role in all phases of the plant’s development, including:
- Operating a test plant at the site during the project’s initial stages
- Testing of ESCLA heat exchangers for the production of hot water during final feasibility phase
- Development of the PLC and SCADA system, consisting of:
- A cold water pump station at Lake Thingvellir, 7 km from the main plant
- A 66/11 kV substation and grid connection
- A 14 bar steam plant
- 3 bar low pressure steam plant
- Heat exchangers, aerators and hot water pump station.
