Business Details

Provides EPC (Engineering, Procurement, and Construction) for energy-saving equipment such as cogeneration systems, fuel conversion equipment, and utility equipment, as well as renewable energy equipment such as solar, biomass, and battery storage systems. Operates in two formats: the "contract-based" format in which EPC is contracted from customers, and the "development-type" format in which the Group leads the entire development process from land acquisition. This is a flow-type business that builds a complementary relationship with the Energy Supply Business (stock-type).

Recent Overview

Contract-based EPC (battery storage systems) drove revenue up 39.2% year on year, but profit fell 23.4%

In the cumulative third quarter of FY2026 (ending March 2026) (July 2025 to March 2026), Engineering Business revenue increased significantly to ¥16,442 million (up 39.2% year on year). In the contract-based format, an increase in battery storage system projects contributed, while the number of energy-saving equipment (CGS, fuel conversion, utility equipment) projects declined slightly. Development-type EPC had no new projects in the period, resulting in no sales recorded. Segment profit decreased to ¥593 million (down 23.4% year on year), with profit margin declining despite the increase in revenue.

Key Products

service
Energy-Saving Equipment EPC (Contract-based)

Provides EPC tailored to customers' needs for energy conservation, cost reduction, and environmental measures, covering cogeneration systems (CGS), fuel conversion equipment (from oil to natural gas), and utility equipment. In the cumulative third quarter, the number of projects declined slightly year on year.

service
Renewable Energy Equipment EPC (Contract-based)

A format in which EPC is contracted for power generation facilities and self-consumption power generation equipment utilizing FIT and FIP certifications obtained by customers. In the cumulative third quarter, this progressed favorably due to an increase in battery storage system projects, driving overall sales growth in the contract-based format.

service
Development-type EPC

A format in which the Group takes the leading role in land acquisition (or leasing), obtaining permits and rights, and EPC. In the cumulative third quarter, there were no new development-type EPC projects, resulting in no sales recorded. In the same period of the prior year, construction of the Kagoshima FIT solar power plant (approximately 8.0MW) had been completed in the previous fiscal year.

service
Grid-connected Battery Storage EPC

Against the backdrop of expanding demand for battery storage systems as renewable energy becomes a mainstay power source, the Company develops EPC for grid-connected and commercial/industrial battery storage facilities. In the cumulative third quarter, an increase in battery storage system projects contributed to the increase in overall sales of contract-based EPC.

platform
Energy Management System "TESS WebView"

An energy management system that remotely monitors and manages customers' energy equipment. It supports the building of ongoing relationships with customers after EPC delivery, and promotes collaboration with O&M and the Energy Supply Business.

Growth Drivers

  • Expansion of project scale for energy-saving equipment (CGS, fuel conversion, utility equipment) EPC amid growing decarbonization needs
  • Increase in EPC orders due to the expanding adoption of battery storage systems (grid-connected and commercial/industrial), driving revenue growth in the current period
  • Capturing demand for FIT solar power plants converting to FIP plus the addition of battery storage systems
  • Acceleration of renewable energy equipment investment driven by policy support such as the 7th Strategic Energy Plan (approved by the Cabinet in February 2025) and the GX2040 Vision
  • Medium- to long-term expansion of capital investment demand toward the goal of a 40-50% renewable energy ratio in the domestic power generation mix by FY2040 (ending March 2041)

Risks

  • Risk of revenue fluctuation inherent to flow-type businesses, whereby development-type EPC revenue is discontinuous depending on the presence of projects (development-type revenue was zero in the current period)
  • Despite a 39.2% year-on-year increase in revenue, segment profit decreased by 23.4%, indicating a risk of declining profit margins due to rising construction costs and other factors
  • Risk of rising construction costs due to surging prices of materials and energy
  • Risk of increased procurement costs due to the continued depreciation of the yen
  • Risk of fluctuation in demand for renewable energy equipment EPC due to revisions to the FIT/FIP system or declines in fixed purchase prices
  • Risk of constraints on order fulfillment capacity due to a shortage of engineering personnel and difficulty in hiring
