Reasons for Kyudenko developing the “Kyudenko EMS”
Internal combustion power is still the main form of power in
remote islands/areas
There is a high cost of transporting fuel to remote islands/areas.High CO2 emissions.

Realization of an independent power supply of 100% renewable energy
Figure: Overview of Huis Ten Bosch Demonstration Facility
● With the cooperation of the Huis Ten Bosch Technical Center we constructed a 100% renewable energy power generation system within their villa area (completed in July 2015).
● Developed an EMS to control the efficient supply and demand for energy, with a demonstration project underway.
● At the end of 2015, Kyushu Electric Power lines were cut off, with all the needed electric power covered by the power generated at the villa management center.
Implementing an overseas demonstration project on Sumba Island, Indonesia, as a Ministry of the Environment Subsidized Project
Stable power from renewable energy sources is supplied with our EMS to the microgrid operating in the Western part of Sumba Island (population about 650,000). Attempting to provide stable power supply from renewable energy as the regional power grid
Existing Facilities Improvement Target
State in which proper power supply/demand operation is not possible, and power generation and storage are not constant
By controlling the generation and storage of renewable energy by EMS, it is possible to autonomously supply stable power for a fixed time/in certain amounts.
