Tepco Solution Advance and Accenture Sign Partnership Agreement for AI-Driven Transformation

[Tokyo, June 4, 2026] Tepco Solution Advance Co., Ltd. (Headquarters: Minato-ku, Tokyo; President and Representative Director: Akira Tanebashi; hereinafter "Tepco-sa"), a company handling outsourced operations for the Tokyo Electric Power Company (TEPCO) Group, and Accenture Japan Ltd (Headquarters: Minato-ku, Tokyo; President and Representative Director: Dai Hamaoka; hereinafter "Accenture") have signed a 5-year transformation partnership agreement. The purpose is to transform Tepco-sa's business operations to leverage the latest technologies, including AI.

Through this partnership, Tepco-sa will move away from traditional labor-intensive operations and shift its business model towards providing transformative BPO (Business Process Outsourcing) services based on AI and digital utilization. This aims to realize the vision set forth in Tepco-sa's TSA2040Vision: "To provide new value by utilizing expanded customer touchpoints through operations that integrate people and digital."

Furthermore, as the business environment surrounding the electric power industry undergoes significant changes, Tepco-sa will leverage the expertise cultivated through its specialized business outsourcing in the power sector. By upgrading business design and operational models themselves, the company will simultaneously promote operational sophistication and cost structure optimization, aiming to create over 10 billion yen in cumulative value over the five-year period. Additionally, through these efforts, Tepco-sa aims to establish a business foundation capable of autonomously generating value. Looking ahead, the company envisions contributing value to the infrastructure industry facing labor shortages, expanding services not only to the power sector but also to other social infrastructure operators, thereby pursuing further value creation.

Overview of the Partnership (Key Pillars)
This partnership aims to enable Tepco-sa to autonomously operate an AI-driven business, with Accenture jointly promoting the transformation from conception to execution and embedding. The initiative consists of the following three main pillars:

1. Joint Construction and Implementation of a Digital Foundation Leveraging AI
This involves the phased planning, implementation, and operation of applications, architecture, and infrastructure necessary for AI utilization. Furthermore, including coordination with the group's IT structure, the partnership will promote optimal overall implementation through requirement organization, progress management, and issue visualization for developing the AI utilization base.

2. Visualization and Efficiency of Operations
For target operations, this involves visualizing current operations, formulating efficiency measures, designing future (To-Be) operations, and creating and promoting execution plans. Concurrently, methods and know-how for visualizing operational status and managing utilization rates will be introduced, with the goal of embedding them within Tepco-sa through on-the-job training (OJT).

3. Transformation Oversight and Promotion
This involves establishing an oversight and promotion structure for reform, visualizing business operations, change management, and renewing the operational model, including the development of personnel capable of self-directed work. Progress and effects will be monitored through regular steering committees and other means to continuously drive transformation.
