■Business Overview of Yondenko ＜1939＞
1. Business Overview
The reporting segments are equipment construction business, leasing business, and photovoltaic power generation business. The equipment construction business has two main pillars: power transmission and distribution equipment construction for electric power companies and transmission and distribution companies in the Shikoku area, which has been the company's core business since its establishment, and construction equipment construction (electric/air conditioning/plumbing equipment construction, information communication equipment construction, system control work, etc.) for office buildings, commercial facilities, logistics facilities, public facilities, factories, etc. It has strengths in technical ability that can provide everything from electrical equipment construction to air conditioning/water supply/drainage equipment construction in one stop, and high-quality construction and maintenance capabilities. The leasing business leases construction machinery, vehicles, equipment, etc. The solar power generation business sells electricity from solar power generation. Also, as other businesses, we are engaged in CAD development and sales business, and PFI/designated manager business that entrusts the design, facility maintenance, and operation management of public facilities.
(1) Power transmission and distribution equipment construction
Power transmission and civil engineering work mainly involves construction related to power transmission equipment (transmission lines, steel towers, etc.) to send electricity from power plants to substations in various places. Since there are many large-scale constructions in Yamanaka, the construction period is long. The company's main role in construction is site supervision, and site management is carried out by ordering construction work from cooperating companies. Power distribution work involves construction related to power distribution equipment (electric wires, utility poles, etc.) necessary to send electricity transformed (step-down) at substations to enterprises and households. Based on contracts concluded with power transmission and distribution companies in advance, a huge number of construction projects are carried out while moving construction sites on a daily basis. We have established a close cooperation system with exclusive cooperating companies for construction.
(2) Building equipment construction
Electricity/air conditioning/water supply and drainage equipment construction involves electric/instrumentation work such as indoor electrical wiring and air conditioning/plumbing work for all kinds of buildings such as office buildings, commercial facilities, logistics facilities, public facilities, factories, etc. In addition to receiving orders directly from clients, we also receive orders from general contractors, and we have a lot of construction experience, such as responding to orders for special facilities such as large-scale factories and hospital operating rooms. The company's main role in construction is site supervision, and site management is carried out by ordering construction work from cooperating companies.
(3) Information and communication construction
It contributes to network infrastructure construction compatible with advanced communication, etc., including maintenance and operation support, such as optical cable installation and mobile phone base station construction by telecommunications carriers, and disaster prevention radio construction and fire radio construction contracts by local governments. The company's main role in construction is site supervision, and site management is carried out by ordering construction work from cooperating companies. System control work involves instrumentation work related to control, such as improving line efficiency at production plants and automating logistics warehouses. Utilizing the strength of in-house programming, energy saving and time reduction have been achieved by constructing a system according to site conditions and making quick updates after operation starts.
(4) Leasing business
In the leasing business, the subsidiary Yonko Business leases construction machinery, vehicles, equipment, etc., and there are leasing transactions with the company. While aiming to expand sales by developing new business partners, etc., efforts are also being made to reduce costs, such as thorough credit management.
(5) Solar power generation business
Subsidiaries Yonko Solar and the like sell electricity generated by solar power generation. Furthermore, in 2023/12, three companies, Shikoku Kasei Kogyo Co., Ltd., Shikoku Electric Power Company, and Yonko Solar, which are subsidiaries of Shikoku Kasei Holdings ＜4099＞, signed an agreement on an off-site corporate PPA (Power Purchase Agreement) using solar power generation in order to realize a carbon-neutral society. This is the first offsite PPA business for the company group. Yonko Solar becomes a power generation operator, and a solar power plant is installed at Umeike in Miki-cho, Kagawa-ken, and supplies the generated renewable energy power along with environmental value (non-fossil certificate) to the Shikoku Chemical Industries Tokushima Plant via Shikoku Electric Power. The supply of renewable energy power is scheduled to begin in 2025/2, and the total power generation output is expected to be 2,035 kW, and CO2 reduction is expected to be approximately 1,503 tons per year.
(6) Other businesses
The CAD development and sales business develops and sells the company's own construction equipment CAD “CADEWA (CADEWA)” series and the construction equipment industry support software “CRAFT DX (Craft DX)” series. Sales of the new version “V2” of the “CRAFT DX” series began in 2024/2.
