To whom it may concern,Mizuho Leasing Co., Ltd.
Acquisition of Equity Interest on The Rooftop Photovoltaic Power Generation Businessin 235 Locations throughout Japan
Mizuho Leasing Company, Limited (hereinafter “Mizuho Leasing”) hereby announces that equity interest on therooftop photovoltaic power generation business (in 235 locations and a total of 31MW of electric energy)
operated by Dairoku Nihon Solar Power LLC (hereinafter “Dairoku Nihon Solar”) was acquired.
This case deals with the rooftop photovoltaic power generation business developed by Daini Denryoku K.K.
(headquartered in Chuo-ku, Osaka, Chairman and CEO : Susumu Okamoto; hereinafter “Daini Denryoku”)
which rent roofs of factories and offices owned by third parties, and the total sum of power output is 31 MW.
The rooftop photovoltaic power generation facility can be developed in a relatively short period of time without
land preparation. The number of facilities adopting this solar system is increasing as it is a renewable energy
power source with little impact on the environment. The power generated from such facilities is for selfconsumption (Note 1) and sold under a feed-in tariff.
The self-consumption model adopts the PPA model (Note 2). From the perspective of ‘local production for local
consumption’ and its additionality (Note 3) of being a source of renewable energy production, the selfconsumption system has gathered attention. Also, for electricity consumers, there are benefits such as; low
initial costs, low equipment maintenance and management costs for this PPA model.
Daini Denryoku is one of the group companies of Choshu Industry Co., Ltd. (headquartered in Sanyo-Onodashi, Yamaguchi, President: Susumu Okamoto) which deals with solar power systems, hydrogen energy
infrastructure systems, biomass energy and semiconductor manufacturing equipment. Daini Denryoku started
participating in the electricity utility industry from 2012, which mainly dealt with solar systems for rooftops. Now
it has grown into a company with a rich background in the installation of photovoltaic power generation systems
on roofs in a total of 1,760 locations.
