Joint Delivery of Construction Materials Launched in Boso Area, Chiba Prefecture

Tokyo Electric Power Grid Corporation (Head office: Chiyoda-ku, Tokyo; President and CEO: Yoshinori Kaneko; hereinafter "TEPCO PG") and NTT East Corporation (Head office: Shinjuku-ku, Tokyo; President and CEO: Naoki Shibuya; hereinafter "NTT East") today launched joint delivery of construction materials (transformers, routers, etc.) for both companies in the Boso area of Chiba Prefecture (Narita City, Mobara City, Kisarazu City).

This initiative represents a new endeavor in which operators from different industries—electricity and telecommunications—collaborate to jointly handle the delivery of construction materials.

1. Background

In recent years, the logistics sector has faced growing pressure to reduce driver workload and improve transport efficiency amid labor shortages and declining delivery capacity. For infrastructure operators, streamlining and upgrading transportation logistics is a critical challenge in ensuring stable supply of materials while addressing environmental impact. Furthermore, building an efficient transport system during normal times enhances resilience and applicability in the event of disasters. TEPCO PG and NTT East, together with Tokyo Gas Network Co., Ltd., have concluded a cooperation agreement among three companies supporting gas, electricity, and telecommunications social infrastructure※1, and are advancing collaboration to improve operational efficiency, create social value, and resolve regional challenges by mutually leveraging each company's management resources and data. The companies have already collaborated in various areas toward the sustainable and stable operation of infrastructure businesses, including strengthening disaster response capabilities and promoting joint inspections. The joint delivery of construction materials was realized as a result of exploring logistics collaboration under this agreement.

2. Initiative Overview

TEPCO PG and NTT East today launched joint delivery of construction materials for both companies in the Boso area of Chiba Prefecture (Narita City, Mobara City, Kisarazu City).

Under this initiative, NTT East's construction materials are transported from NTT East's logistics warehouse (Kazo City, Saitama Prefecture) to TEPCO PG's logistics warehouse (Chiba City, Chiba Prefecture), where they are consolidated and then delivered together with TEPCO PG's construction materials via mixed loading by TEPCO PG.

The Boso area of Chiba Prefecture was selected as the pilot region because NTT East's delivery routes pass near TEPCO PG's logistics warehouse, and the delivery destinations of both companies are geographically close, confirming high compatibility for joint delivery.

3. Pilot Experiment Overview and Results

Prior to launching joint delivery, a pilot experiment was conducted to verify the effectiveness of the above scheme.

(1) Pilot Experiment Overview

Joint delivery using TEPCO PG's logistics warehouse as a relay hub was tested under the following conditions:

Target area: Boso area, Chiba

Frequency: 3 times total (April 17, April 24, and May 15, 2025)

(2) Pilot Experiment Results※2

The pilot experiment confirmed the following per-day effects across each evaluation metric:

Number of trucks: reduced by 1

Total distance traveled: 15% reduction

Total travel time: 11% reduction

Average load factor: 14% increase

Total cargo handling time: 40% reduction

CO2 emissions: 13% reduction

As meaningful results were confirmed across all evaluation metrics in the pilot experiment, the companies decided to formally launch joint delivery in this area.
