Future developments

● O erseas● Overseas

・ Micro-grid system based on a local characteristic.

Th i d d l b BEMS・ The various demand responses control by smart BEMS.

● Domestic・ Optimal power and demand control corresponding to the

power system reform.

・Contribution to introduction expansion of the renewable energy.

・Heat and power supply by the cogeneration system.

・Stable and high-quality islanding operation at the time of the emergency. (BCP measures)
