Varmaorka is an Icelandic project developer that focuses on harnessing geothermal resources in areas where heat temperatures are approximately 100°C. Varmaorka develops, finances, constructs and operates small scale geothermal facilities in Iceland.
Flúðir might be best known for it’s natural hot spring the Secret Lagoon, the more subdued little sister of the popular Blue Lagoon, but this village of nearly 400 inhabitants is also the source of one third of the vegetables on Iceland, and home to the largest mushroom farm. And as you can imagine, keeping greenhouses operational during the long, dark winter months requires a lot of power.
The Flúdaorka Power Plant is located just outside Flúdir in southeast Iceland. The area is rich in geothermal heat, mainly used for district heating and green houses. There was an existing well, not in operation, when the planning of the power plant was initialized.
The power plant is compact in size consisting of a well pump, four Climeon HP units, a cooling circuit with wet cooling towers and a transformer station (see overview of the power plant shown in Figure 1).
The construction of the power plant began in May 2018 and commissioning was finished in March 2019. While this was record timing in Iceland, we've collected intelligence throughout the process in order to significantly decrease this time for future installations in Iceland through our planned expansion with Varmaorka.
Site automation was included in Climeon’s scope of supply. By adjusting the cooling towers and the HP 150 operation points it gives us the opportunity to optimize the site net power output. This optimization is ongoing and we are continuously developing the automation software to monitor performance and maximize power output.
