Geothermal energy is available all over Finland. However, the amount and usability of geothermal energy vary locally and regionally, which has a decisive impact on the design and implementation of geothermal energy systems. GTK offers comprehensive evaluation of regional geothermal energy potential, taking into account all geological factors affecting geothermal energy.
Geothermal energy can be utilised all over Finland, but there is local and regional variation in terms of volume and usability. Knowledge of the regional factors affecting geothermal energy potential enables more efficient energy utilisation – precisely where it is most profitable in each region.
An evaluation of geothermal energy potential helps to identify the regional applications of geothermal energy in the production of low-carbon heating and cooling energy. Evaluations of geothermal energy potential are commissioned by, for example, municipalities and regions with the aim of providing information and promoting the wider utilisation of geothermal energy in the area. Evaluations can also be carried out for smaller areas, such as at the initiative of a regional real estate development company.
In-depth knowledge of the regional geothermal energy potential allows for more comprehensive use of low-carbon geothermal energy in the area.
Evaluations of regional geothermal energy potential analyse, for example, the amount, usability, and variation of heating and cooling energy within the earth – which are all dependant on geological factors – at the level of an individual building block, municipality or region. Our experts will carry out the evaluation based on the following areas.
GTK uses and maintains Finland’s most comprehensive geoscientific datasets, which can also be utilised when evaluating the regional potential of geothermal energy.
Our experts consider all geological factors affecting geothermal energy, both in the soil and in the bedrock. Of the individual factors, the thermal conductivity of bedrock and temperature of the ground have the greatest impact on geothermal energy potential, but other factors also affect the amount and usability of geothermal energy.
GTK can determine the potential of geothermal energy at different depths according to the customer’s needs. For example, our experts can calculate the amount of deep geothermal energy available for use in district heating. In addition, GTK has developed new methods for calculating geothermal energy potential numerically, instead of mere verbal qualitative evaluations.
