As a result, government assistance and incentives are an important aspect of the global geothermal turbine market trend.
Developing geothermal power projects requires exploration, drilling, and infrastructure investments. Exploration of geothermal resources can be costly, especially in areas with no recent geothermal development. With its immense geothermal potential, Indonesia exemplifies the difficulties of substantial initial investment. Creating new geothermal fields in remote places necessitates major investment in discovery, drilling, and power plant construction. For example, the Sarulla Geothermal Power Plant in North Sumatra, Indonesia, required a significant investment of more than USD 1.17 billion. The cost breakdown of a geothermal power project, according to the U.S. Department of Energy, typically includes exploration and drilling (up to 30% of total project cost), surface power plant (30-40%), and transmission and interconnection (10-20%).
Concurrently, the cost of producing geothermal electricity in India is considerable. If the site must be drilled more than 200 meters, it costs Rs 40 crores (about $5.3 million) to create 1 M.W. As a result of the large initial capital needs, emerging economies may struggle to attract investments, stifling the spread of geothermal energy in these countries.
Geothermal energy is a reliable and consistent choice as the globe attempts to lessen its dependency on fossil fuels and migrate to renewable energy sources. The switch to renewables creates prospects for geothermal power capacity increase. Geothermal energy, being a renewable resource, meets a large portion of electricity demand in nations such as Iceland, El Salvador, New Zealand, Kenya, and the Philippines, and more than 90% of heating demand in Iceland. Iceland's Hellisheii Geothermal Power Plant. Iceland's Hellisheii Geothermal Power Plant is one of the world's largest geothermal plants.
