Energy Business

Renewable Energy Initiatives

MIRARTH HOLDINGS Group promotes energy projects that utilize renewable energy sources that contribute to the reduction of CO₂ emissions. Since 2013, when we entered the energy business, we have been developing mega solar power plants and small- and medium-scale solar power plants on idle land and other sites across Japan, with a total generation capacity of approximately 360 MW as of March 31, 2023.

In addition, we are also involved in other renewable energy projects other than solar power generation, such as wind power and biomass.

Other Group Achievements

Leben Solar Tottori Daisen Power Plant

In August 2022, Takara Leben, which has been developing mega solar power plants by installing solar panels on sites unsuitable for building construction or idle land, held a completion ceremony for the Leben Solar Tottori Daisen Power Plant, which utilizes a former golf course site in Saihaku-gun, Tottori Prefecture.

The plant is the largest power plant developed by the our group in the Chugoku region, generating approximately 16.5 million kWh of electricity per year, which is equivalent to the electricity supply for approximately 4,800 households. In addition to the longer mounting piles to prevent snow damage, double-sided power generation modules are used to convert reflected light from the ground surface onto the back of the panels as well as the front of the panels, resulting in greater power generation even in a limited space.

Efforts to promote PPA

MIRARTH HOLDINGS and Leben Clean Energy have signed a memorandum of understanding (MOU) on solar power generation business with Mitsui & Co. Plant Systems to jointly develop Offsite Corporate PPA* to realize a decarbonized society.

With a track record of developing more than 200 high-voltage solar power plants nationwide, Leben Clean Energy is the core company in the renewable energy business of MIRARTH HOLDINGS Group. We are developing renewable energy, particularly solar power, to meet the growing decarbonization needs of our customers while building a business model that does not depend on feed-in tariffs (FITs). In recent years, the number of large-scale solar power generation sites has been on the decline, and we have been speeding up the development of medium- and small-scale solar power plants across Japan. This collaboration with Mitsui & Co. Plant Systems is part of our efforts to quickly build a development system and commercialization of such plants.

In addition, MIRARTH HOLDINGS is also promoting activities with a view to supplying post-FIT renewable energy by conducting a tender offer for units of Takara Leben Infrastructure Fund through a limited liability company it has established. By actively and continuously developing projects through Leben Clean Energy, we will work to develop more non-FIT solar power plants, etc.

Going forward, the company plans to continue to provide solutions to a large number of customers through the project development capabilities of Leben Clean Energy, the project management capabilities of Mitsui & Co. Plant Systems, and the extensive network of the Mitsui & Co. group.

*Offsite Corporate PPA: A system in which solar power plants are installed on idle land, etc., in remote areas throughout Japan, outside customer demand areas, and electricity or environmental value is supplied using the existing power grid owned by a general transmission and distribution utility.

Biomass Power Generation

In 2021, MIRARTH HOLDINGS entered the biomass power generation business for the first time in the company’s history. The Fuji Asagiri Biomass Power Plant (Fujinomiya City, Shizuoka Prefecture), which is currently in trial operation to start selling electricity in FY2022, generates biomass power using cattle manure collected from members of the Fuji Kaitaku Agricultural Cooperative Association. The power plant generates electricity by burning biogas generated from the fermentation process of cattle manure, which emits less CO₂ than the direct combustion of wood waste and combustible waste. The liquid fertilizer produced with the biogas will be marketed as Fuji Asagiri Biomass Liquid Fertilizer.
This project follows our solar power initiative as the second renewable energy venture. It aims to create a regional, recycling-oriented symbiotic zone, supplying clean energy through effective waste material utilization and addressing the issue of cattle manure disposal.

LS Chiba Sammu East & West Power Plants Sign Specified Wholesale Supply Agreement with Minna Denryoku Co.

Green Energy, a limited liability company whose asset management is entrusted to Takara Asset Management, has concluded a specified wholesale supply contract with Minna Denryoku (currently UPDATER Inc.) for the LS Chiba Sammu East and West Power Plants. Minna Denryoku is developing a service that connects electricity producers and users with renewable energy. Through Minna Denryoku, we aim to promote a decarbonized society and the spread of renewable energy by supplying energy to households that choose energy with low environmental impact and to companies that practice environmentally friendly management.

Measures to Reduce CO₂ Emissions

Takara Leben Infrastructure Fund and Green Energy, a limited liability company, aim to create a sustainable, earth-friendly environment through investment in renewable energy generation facilities and other assets, contributing to the reduction of CO₂ emissions by approximately 76,302 tons per year*.

* Annual amount of reduction of CO₂ emissions compared to fossil fuel-fired thermal power plants based on the output of power generation facility panels.

Takara Leben Sustainability Fund

Takara Leben has begun operation of new means of financing with the aim of encouraging measures that contribute to the global environment. Leben Funding LLC. was established in January 2021, and in collaboration with Funds, Inc., it launched the Takara Leben Sustainability Fund #1~3 and conducted crowdfunding to solicit loan investments from a wide range of investors. The collected funds will be used as working capital for renewable energy projects and Sustainability (CSR) measures.
