Susono Biomass Power Generation LLC ("the project company"), a joint venture of Chubu Electric Power Co., Inc. ("Chubu Electric Power"), ML Power Company, Limited ("ML Power") which is a wholly owned subsidiary of Mizuho Leasing Company, Limited ("Mizuho Leasing"), and PROSPEC AZ Inc. ("PROSPEC AZ"), today started construction of the Susono Biomass Power Station ("the station").
The station is a wood-fired biomass plant to be constructed in Susono, Shizuoka Prefecture, which will generate 1,990 kW of electricity, mainly from pruned branches (Note) of roadside trees in the prefecture, and is scheduled to start operation in October 2025.
(Note) Branches cut down for tree shaping or to maintain tree size.
Together with the understanding and cooperation of the local community and other stakeholders, we, all three investors and the project company, will proceed with the construction of the station, placing safety as the highest priority.
In addition, the three companies have decided to develop wood-fired biomass power stations with an output of 1,990 kW in the cities of Shibukawa in Gunma Prefecture, Nagano in Nagano Prefecture, and Joetsu in Niigata Prefecture ("Shibukawa Biomass Power Station," "Nagano Biomass Power Station," and "Joetsu Biomass Power Station," respectively) that will use pruned branches from roadside trees as their main fuel. Through their operating companies, we will proceed with our plans to commence operations in November 2025, April 2026, and May 2027, respectively.
The three companies will contribute to the reutilization of waste materials and the realization of a regional recycling-oriented society through these efforts by using pruned branches, which have been disposed of or incinerated, as fuel for power generation.
