Having 8 facilities within the Tokyo Electric Power Company and Tohoku Electric Power Co service areas, Kyocera has increased the size of the rooftop solar power system at its Tanagura manufacturing plant in Fukushima Prefecture, to meet energy reduction targets of 15%, due to the power consumption regulations dictated after the Fukushima nuclear power disaster.

Kyocera said that solar power generation system at its Tanagura plant was now the largest PV installation at its domestic plants, having installed a further 194kW of power, increasing the rooftop power to 230kW, compared to only 36kW, previously installed. 

However, the increased power system will cover only 8.2% of the facilities energy use, so to meet the 15% energy-reduction target, Kyocera will be undertaking various measures such as using power generators, setting air-conditioning to 28 degrees Celsius (82.4 F), turning off unnecessary lighting, and setting all office computers to low-power mode to meet requirements, especially during the summer months peak energy needs in Japan.

Kyocera also noted that 26 locations in its global network are solar power-equipped with a total of over 2.2MW installed. Recently, the company also installed a 130kW system at Kyocera Elco Corporation's new headquarters and a 58kW solar power generating system at its Yokohama Sales Office.
