Buddy Net Co., Ltd. (Headquarters: Chuo-ku, Tokyo, President: Seiji Tsutsumi, hereinafter "Buddy Net") and Tess Engineering Co., Ltd. (Headquarters: Yodogawa-ku, Osaka, President: Toshihiro Takasaki, hereinafter "Tess Engineering") signed a business alliance agreement (hereinafter "this business alliance agreement") on April 10, 2026, with the aim of building a comprehensive cooperative system from project origination to the construction of a construction system for the energy storage power plant development business.
This business alliance agreement aims to further improve the corporate value of both companies by setting the realization of a decarbonized society and the strengthening of the resilience of local communities through the spread of next-generation energy infrastructure as a common vision. In addition, in order for both companies to develop mutually, we will utilize our respective areas of expertise, management resources, know-how, etc., and cooperate in the introduction of customers and projects related to the energy storage power plant development business, as well as the ordering of construction work or related equipment.
■ Background and social significance of the conclusion of this business alliance agreement: "Energy storage power plants" as the cornerstone of GX promotion
With the global transition to carbon neutrality, the promotion of GX is an urgent issue in all industries in Japan. At the same time, from the perspective of BCP (Business Continuity Planning) against increasingly severe natural disasters, improving energy resilience is an unavoidable issue.
Against this background, Buddy Net hopes to play a part in solving these issues by promoting the social implementation and spread of "energy storage power plants," which are the cornerstone of next-generation infrastructure. Through this alliance, we will build a resilient distributed energy network that will become a "lifeline" for society in the event of large-scale disasters, and contribute to the realization of a sustainable society by contributing to the creation of towns that are environmentally friendly, highly resistant to disasters, and "sustainable to live in."
■ Synergies created by both companies and the value provided by Buddy Net
In the energy storage power plant development business, the key to business success is not only the superior performance of the equipment, but also the "reliable implementation capability on site" that maximizes it.
In this alliance, we will highly integrate the customer network, business development know-how, and engineering capabilities possessed by Tess Engineering with the nationwide construction capabilities, construction know-how, and on-site technical capabilities possessed by Buddy Net. This will build a solid business promotion system that seamlessly covers everything from "planning and development" to "on-site implementation" in energy storage power plant projects. This strong partnership enables high-quality and speedy project execution even in large-scale projects with high development difficulty and wide-area deployment, strongly backing energy optimization and the realization of a decarbonized society in Japan.
The greatest strength of Buddy Net is that it has an "end-to-end" system that can complete everything from electrical facility construction to civil engineering work such as civil engineering development and foundation work within a single company, based on its nationwide construction and maintenance system.
It boasts an extensive track record in the construction of highly difficult renewable energy facilities, such as high-voltage and extra-high-voltage grid storage batteries and large-scale solar power facilities. By fusing long-standing achievements in the renewable energy and civil engineering fields with advanced communication construction know-how, we provide high-quality total solutions nationwide, from the design and construction of grid storage batteries to maintenance after operation.
