HRV Engineering´s holding companies, Mannvit and Verkís, played a leading role in the design and commission of Reykjavík Energy´s Hellisheiði plant.
The development plan was an incremental or phased expansion. The first phase included two high-pressure 45 MWe turbines that went online in October 2006 and then one low pressure 33 MWe turbine that went online in the fall of 2007. The next expansion phase consisted of two additional 45 MWe turbines that went online in 2008.
The first stage (133 MWth) of three thermal power plants was commissioned in 2010. The final phase puts the thermal capacity at 400 MWth. The last power expansion (phase 5), adding 2 x 45 MWe, went online in 2011.
