The Akita city of Japan will begin the operation of a 1.5MW mega-solar power plant (large-scale photovoltaic (PV) power plant) in a location that was previously the city's general waste disposal site Oct 1, 2013.
The PV panels and PCS (power conditioning subsystem) of the plant were manufactured by South Korea-based Hanwha Group and Toshiba Mitsubishi-electric Industrial Systems Corp (TMEIC), respectively.
This is the first operation of a mega-solar power plant run by a municipality in Akita Prefecture. The power generation facilities are owned by Century Tokyo Leasing Corp, and the Akita city will pay a rental fee for 20 years. The city will receive the income from selling electricity generated by the mega-solar power plant. So, its revenue will be the difference between the income and the rental fee.
The Akita city can reduce the amount of initial investment and business risk because the leasing company will maintain, inspect and guarantee the facilities. A mega-solar business using the same operation method was once established in the Ota city, Gunma Prefecture, Japan.
JFE Engineering Corp was responsible for the engineering, procurement and construction (EPC) of the plant. And Sejimo Kensetsu Kogyo, the Akita city-based construction company, did the civil engineering work. By taking advantage of the land form, etc, it became possible to ensure a large amount of power generation even in the snowy region where sunshine hours are short, the city said.
