IBeeT Co., Ltd. (Representative Director: Yoichi Murakami, hereinafter 'IBeeT') is pleased to announce the formation of the grid-scale storage battery consortium 'Libra LLC' on March 26, 2026. This joint venture involves partners including Tokyu Land Corporation, Fuyo General Lease Co., Ltd., Nomura Real Estate Development Co., Ltd., Maeda Corporation, Nittetsu Kowa Real Estate Co., Ltd., Sumitomo Mitsui Trust Bank, Limited, and Sumitomo Mitsui Trust Panasonic Finance Co., Ltd. The consortium will promote six ultra-high voltage grid-scale storage facilities with a total project cost of approximately 30 billion yen and a total output of approximately 174MW (hereinafter 'the Project').
Operations are scheduled to start sequentially from FY2027. The project aims to contribute to the expansion of renewable energy by supplying the balancing power that is currently in short supply.
### Market Conditions and Significance of the Initiative
Toward achieving carbon neutrality by 2050, the spread of renewable energy has become an urgent issue. However, renewable energy experiences significant output fluctuations depending on weather and time of day. As its adoption grows, the importance of grid-scale storage batteries that complement these fluctuations is rapidly increasing.
IBeeT has previously promoted investments in ultra-high voltage storage facilities, such as the Otoku Storage Station through a joint investment with ReENE Co., Ltd. (a subsidiary of Tokyu Land Corporation), in addition to providing equipment sales and leasing services for Itochu Corporation's grid-scale storage system 'Bluestorage.'
Through participation and investment in this project, IBeeT will further accelerate the supply of balancing power in the power grid, contributing to the further spread of renewable energy and the realization of a sustainable society.
### Consortium Overview
1. List of Investors and Business Partners:
(The consortium includes Tokyu Land, Fuyo General Lease, Nomura Real Estate, Maeda Corporation, Nittetsu Kowa Real Estate, Sumitomo Mitsui Trust Bank, Sumitomo Mitsui Trust Panasonic Finance, and IBeeT.)
2. Target Projects (6 locations nationwide, total output approx. 174MW):
(The project spans multiple regions across Japan to stabilize the local energy supply.)
### About IBeeT's Business
IBeeT was established in 2021 through investments by Itochu Corporation and Tokyo Century Corporation to promote the widespread adoption of distributed energy sources and realize a sustainable and highly flexible energy society.
Since its inception, it has developed sales and leasing for residential solar and storage battery systems, and is now expanding its business scope to industrial and grid-scale applications.
By utilizing the expertise of its shareholders, Itochu Corporation and Tokyo Century Corporation, IBeeT provides total solutions for the introduction of distributed power sources (products, technical expertise, finance, market operation, and after-sales service) to maximize energy value.

FAQ
What is a grid-scale storage battery?
It is a large-scale battery connected directly to the power grid. It serves as 'balancing power' to absorb output fluctuations from renewable energy like solar power, stabilizing the grid and preventing blackouts.
Why are real estate and leasing companies involved?
Because in a decarbonized society, storage batteries are viewed as infrastructure assets capable of generating long-term stable returns, leveraging their expertise in land acquisition and finance.
When will the project start operations?
The consortium was formed in March 2026, and the batteries are scheduled to begin operating sequentially starting from FY2027 at six locations across Japan.
