Act on Purchase of Renewable Energy Sourced Electricity by Electric Utility Companies
(Feed-in Tariff Scheme for Renewable Energy)
This Act obliges electric utility companies to buy electricity generated from renewable energy sources (Solar
PV, wind power, hydraulic power, geothermal and biomass) at the procurement price and for the procurement period.
Approved at the 177th session of the Diet 2011 and started on July 1st, 2012. (2014.04 – 2015.03)

(*2) Apply higher rate than other sources due to the cost of approx. 4.6BYen per project for a site development with surface survey, test drilling of
test, and others, and low success rate(appx.7%) to realize business , etc.

(3) Easing of Regulations of the Natural Parks Act
September 1974
the Environmental Agency(currently Ministry of Environment; MOE） decided to limit geothermal
development to six (6) sites within Natural Parks.
March 2012
MOE decided to ease such regulations so as to implement geothermal development within
National Parks* conditionally.
* Excluding core areas(Special Protection Zone and Special Zone I ) of national parks

3.R&D Projects and Airborne survey
(1) R&D of Geothermal Technology – Reduction of Exploration Risks 11
So far…
The locations of the reservoir blocks have to be
estimated by the various information
The goal is…
To visualize spatial distribution of the fractures
in the geothermal reservoir
Purpose of R&D
Visualize subsurface fractures from the surface more precisely
Develop exploration technology using seismic waves
Develop analysis method integrating seismic data with other exploration
data
How to detect fractures？ Survey fractures

133.R&D Projects and Airborne survey(2) R&D of Geothermal Technology
– Exploration Techniques for Geothermal Reservoir
Original Section (1996) Reprocessed Section (2013)
Example of 2013FY AchievementsSince the recent processing techniques of seismic data have been much advanced in oil and gas
field, we applied these techniques to the data at geothermal fields which was acquired more than a
decade ago.
We recognized the improved image of the main geothermal productive reservoir(faults location
indicated by red arrows), and are expecting the further efficacy by applying the seismic method to
geothermal reservoir exploration.
※Geothermal water recharge
A hydrologic process where surface
water like rainfall moves downward
to geothermal reservoir.
※
Power
Plant
• Some of geothermal power plants in Japan are facing difficulty in producing
necessary amount of steam or hot water stably due to the deplete of the
geothermal fluid.
• To address this challenge, JOGMEC tries to research and development to
stabilize the production of subsurface geothermal steam and hot water by not
only improving accuracy in evaluation of behavior of the fluid, but also
recharging water to the geothermal reservoir.
