Renewable energy and sustainability
Landsvirkjun generates its energy from renewable resources
Landsvirkjun is committed to utilising natural resources in a sustainable manner. The role of the Company is to maximise the potential yield and value of the natural resources it has been entrusted with, in a sustainable, responsible and efficient manner.
The term sustainable development refers to long-term development which focuses on increasing economic value, strengthening society and protecting the natural environment.
October, a good month
October was warm all over the country and temperatures were generally above average with high precipitation until the middle of the month. The first part of October was particularly advantageous for inflow to the reservoirs; less mid-month but increased towards the end of the month.
The water levels at Landsvirkjun‘s reservoirs (by month) can be seen here. Click on the different months above to access information on the power station and water levels.
One of Landsvirkjun’s guiding principles is the responsible and sustainable utilisation of geothermal resources. Landsvirkjun operates two geothermal power stations in the Mývatn area, the Krafla and Bjarnarflag Stations. Moreover, construction work began on the Þeistareykir Geothermal Station in 2015. Landsvirkjun conducts extensive research on the utilisation of geothermal energy in these areas. This includes research on current utilisation and future utilisation in other areas.
Geothermal fluid is composed of steam, water and the various gases present in the steam, and is extracted from the geothermal system at a depth of 2000 metres during the utilisation process. Energy is generated by utilising the steam. Most of the water is then re-injected into the geothermal system (deep re-injection) or released into surface water. The gases are released into the atmosphere.
In 2016, approx. 4,821 thousand tonnes of steam were utilised to generate 496 GWh of electricity in the Mývatn area. The quantity of steam utilised for electricity generation has decreased between 2012 and 2016 which can mostly be attributed to less output of wells. A new well was drilled this year to increase the capacity levels in the area.
The utilisation process produced 6,516 thousand tonnes of condensate water and separated water. The quantity of water in geothermal fluid has increased when compared with the previous year which can mostly be attributed to the use of an older, water-rich and low-temperature well to maintain energy generation levels. Approximately 4,640 thousand tonnes of separated water was re-injected back into the geothermal reservoir which marks an increase from the previous year.
