Country Update: No country update paper was received from this country, thus the geothermal direct-use is estimated from a paper presented at the European Geothermal Congress 2013, and then extrapolated to 2015 (Kallio, 2013). Finland has had a large growth in the number of heat pump installed starting from 2005 with less than 100,000 to 540,000 in 2013. The strongest growth has taken place in airsource heat pumps, but geothermal heat pumps have had a large increase with a record 72% in 2012. Today over half of new residences utilize heat pump technology and an increasing number of office buildings and shopping center are using geothermal heat pumps for heating and cooling. There is a clear trend toward large geothermal heat pumps installations, but still domestic installation are the fastest growing market with >50% of new residences using these systems. The largest installation is in the Logistics Center in the southern part of Finland with 150 bore-hole heat exchangers, each 300 m deep (total 45,000 m). This energy field/installation has been provided by an advanced real-time fiber optic monitoring system designed by the Geological Survey of Finland GTK. There were 90,000 geothermal heat pump units in operation by the end of 2012 and 130,000 units projected by 2015. Approximately 13,000 new units were installed in 2012. By 2015 the expected investment in shallow geothermal heat pump system will be 1,000 million Euros (1,250 million US$). The number of full load hours annually is estimated at 3,340 with an average COP of 3.0. For 2015 the estimated production will be 4.0 to 5.0 TWhr/year (14,400 to 18,000 TJ/yr), with an installed capacity of 1,560 MWt (using an average unit size of 12.0 kW). Using a capacity factor of 3,340/8760 = 0.38, the estimated production is around 18,000 TJ/yr.

No country update paper was received from this country; however, a few estimates were made for 2008 (Jarmo, 2009) for geothermal heat pumps – the only geothermal use in the country.

Based on his estimate, approximately 7,500 geothermal heat pumps units were sold in 2008, or about 40% more than 2007 with a total energy supply of 1 to 2 TWh/yr. Based on the EurObserv’ER 2009 report, the estimate is that 46,412 total units were installed by 2008 for a capacity of 857.9 MWt and the total units installed between 2007 and 2008 was 7,500 units (which is only a 19% increase). Based on data from the WGC2005 world report (Lund, et al., 2005) the number of full load hours annually is 4,000 with an average COP of 3.1.

Thus, based on the EurObserve’ER numbers, the annual energy use would be 8,370 TJ (2,325 GWh/yr) which is slightly higher than Jarmo’s estimate, but is the one that will be utilized.
