In 2012, the national supporting system for the geothermal power generation was reformed. Feed- in tariff for the renewable energy came into effect, and deregulation for geothermal development in natural parks where most of the geothermal resource prospects exist came about. As a result, our surroundings for the geothermal develop-ment was highly improved. Meanwhile, concerns about the environmental impact by geothermal development activity are being expressed by the local people. Eliminating any impact on the environment and co-existence between hot spring business and geothermal industry are primary consideration more than ever. Hereat, the new organization, Japan Geothermal Association (JGA) , has been established by broadly calling for the participation of Japanese geothermal companies with the aim of improving the various common issues of the industry. JGA represents Japanese geothermal industry both in name and reality, and promotes the best utilization of our geothermal energy for all people in Japan.

Let’s seeour Geothermal Power!

Geothermal Power Plants in Japan

So many geothermal plants in Japan!

The total installed capacity of geothermal power plants in Japan as of 2016 is 520,000 kW, which is the 10th in the world.

Geothermal DevelopmentIn Japan on the graph, geothermal development in terms of installed capacity has not expanded since 1996. There are three main reasons why geothermal power plant installed base has not been growing.

Reason 2. National ParkIt is well known that geothermal resources are abundant in Japan, but about 80% of the resources exist in National Parks; thereby limiting geothermal development in National Parks since 1974.

An update to policy in 2012 ushered in an era of geothermal develop-ment allowed in class 2 and 3 special zone especially when the environment is not impacted or local stakeholders agree to allow development. Moreover, the height restriction on architecture under 13m have been eased and directional drilling from outside of the zone to inside of class 1 special zone is approved.

Reason 3. Hot springsHot springs are popular not only for Japanese people but also for foreign tourists in Japan. Hot springs can be found all around Japan, and there are quite a few volcanic hot springs which are located near geothermal development sights.Some of hot springs owners have been reluctant to accept geothermal power plants for fear of adverse effects to their businesses.Contrary to the fears, there are 12 large-scale (over 10MW) geothermal power plants, and the oldest one has been running almost 50 years, and they have not had adverse effects on hot springs resort operators. To mitigate the risk, care must be taken to measure and monitor the well for performance so to prevent negative impact to hot springs stakeholders. Many positive second-ary impacts can come from developing heat source from geothermal development such as supply-ing heat to greenhouses.We have taken steps to work with local communities to educate them about the positive impacts, the commitment we have to them, and our deep respects for the continued operations of the hot springs.

Reason 1. Cost

Geothermal Power Generation in Japan

Geothermal power generation has not received investment by private companies for several reasons; 1. Long cycle times of research and design to deployment, 2. Risk of development of unproven under-ground resources, 3. High investment cost of initial research, and 4. Unstable and low price of electricity pricing as well as the price of steam.Feed in Tariff (FIT) began in 2012; it fixed the price of electricity when selling and helped establish stable investment conditions to enable projects. In addition, the subsidy for initial research and financial support for exploration and development have created favorable economic conditions for growth.

However, they account for only 2.2% of the geothermal resources in Japan! Most of our resources has been

undeveloped yet !

Geothermal Technology in JapanJapan is at the forefront leading high level geothermal research and development as well in the deployment of technology. Japanese manufacturers have led the drive to develop technology of the core components of geothermal power plants and continue to lead the world . Most notably, turbines supplied by Japanese manufacturers account for around 70% of world share of geothermal power plants.
