Wakayama Prefecture gained agreement with a community group, which had led the local movement against the dioxide pollution, before attracting a solar power plant to the site.
"The group welcomed the plan with no particular objections," a prefectural government officer said.
The group, however, made one condition: that the area where the concrete container is buried be excluded from the construction area, citing concern that the polluted soil sealed underground might leak. The amount of power generation would be decreased accordingly.
Power supply that local people can use during major blackouts
This power plant also plays the role of a power supply that local residents can use at times of major blackouts. By switching to the PV inverters featuring stand-alone operation capabilities during a blackout, power can be supplied to electric devices from the emergency power outlets attached to the mounting systems (Fig. 3). Simple emergency sheds to store portable batteries that can be used as night-time shelters, etc., and reserve stocks for disasters were also set up (Fig. 4 & 5). The proposal for these contributions to the local community was one of the reasons why Kokusai Kogyo was selected from the candidates.
The land where "the determination for realizing a recycling-oriented society" was pledged is now covered with solar panels.
