Kakkonda地热田支持由日本金属化工株式会社和东北电力公司运营的50兆瓦发电站。该发电站自1978年以来一直在运营。目前，另一座发电厂(30MWe)计划于1996年3月开始运行。Kakkonda热液系统在温度和渗透率方面都有两个不同的储集层。浅层储层渗透率较高，为2 30~2 60Ž，深层储层渗透率较低，大于30 0·<C.
The Kakkonda geothermal field supports a 50MWe power station operated by Japan Metals and Chemicals Co., Ltd. and Tohoku Electric Power Inc. The station has been in operation since 1978. Currently, an additional power plant (30MWe) is scheduled to start operation in March 1996. The Kakkonda hydrothermal system has two distinct reservoirs both in temperature and permeability. The shal low reservoir is very permeable and 230 to 260• Ž whereas the deep reservoir is less permeable and more than 300•‹ C.
