Sigrant, a Wakayama-based trucking, real estate, and construction company, plans to build an 800kWAC/1.1MWDC solar power plant in Katsuragi Town, a June 2025 certification filing under the prefecture’s renewable energy ordinance shows.
According to the application filed by Osaka-based renewable development consultancy Aruma, the power plant will not operate under the fixed price per kWh feed-in-tariff (FIT) scheme. Sigrant has not disclosed whether it will monetize the asset via a PPA or other means.
Construction is expected to be completed within six months of certification by the prefecture. The facility will be sited on a 9,278m2 plot of land in the town’s Shimoamano area and consist of 1,748 Trina Solar panels coupled with Huawei power conditioners. It is expected to operate for 20 years, until the end of 2045.
METI and Wakayama Prefecture data suggest it will be the second largest solar asset in Katsuragi Town after a 990kWAC/1.3MWDC system commissioned under FIT by Daiwa Energy in 2013. As of May 31, 2025, METI’s FIT/FIP ID database listed no Sigrant projects, indicating the Shimoamano power plant is likely to be the company’s first foray into power generation.
Wakayama Prefecture promulgated its ordinance regulating renewable development in 2018. Since then, 66 projects were certified, four were rejected, and two canceled.
