1.1MW Solar Plant Operates for 5 Yrs, Funded by Local Community
Preventive maintenance carried out, PV inverters to be repaired as scheduled
Mima City, located inland in Tokushima Prefecture, is an area with a traditional country landscape, of mountains, a river and flat vegetable fields. The city also has the Yoshino River and the prefecture's highest mountain, Mt. Tsurugizan (1,955m above sea level).
Flanked by the Tokushima Expressway, which runs a little distant from but almost in parallel with the Yoshino River, is the "Mima Solar Valley," a mega- (large-scale) solar power plant with a solar panel capacity of 1.189MW and a grid capacity of 1MW (Fig. 1).
Gaia Power KK of the Fujisaki Electric Co Ltd Group (both in Anan City, Tokushima Prefecture) led the development and operation of this power plant, which started generating power about five years ago in December 2012.
This was the first mega-solar plant developed by Gaia Power, which has developed many solar power projects since then. As of today, it has started operating power plants in 19 locations.
The mega-solar plant in Mima City is a project in which many local enterprises and citizens are participating in a wide range of areas, from land to funds and operation.
As for land, the plant utilizes an idle site owned by a local general contractor, the Kitaokagumi Group (Mimacho, Mima City). The Kitaokagumi Group owns many plots of land in this area and operates factories for construction materials and other products around this mega-solar plant.
The Kitaokagumi Group provided this site as well as engineering, procurement and construction (EPC) services together with Gaia Power.
In the Kitaokagumi's adjoining site to the south of this mega-solar plant in Mima, the "Mikan Solar Valley" with an output of 1.328MW is being developed (Fig. 2). Gaia Power also partly financed the power producer and provided EPC services at this mega-solar plant.
