The safety operations at power generation facilities have seen significant improvements with the introduction of REMOKEN, our proprietary remote inspection service using drones and AI. This innovative service is currently patent-pending.

What Makes Us Different

01Remote Monitoring and Regular Maintenance

To ensure stable power generation and supply, we have established a streamlined process for planned regular inspections and emergency checks following natural hazards.. By implementing a cycle of remote monitoring and countermeasures, we achieve a high level of “safety, stability, and reliability,” which forms the foundation of our power plant operations.

02Maximizing Power Generation

A key mission of our operations is to fully unlock the potential of our facilities and maximize power output.
We support optimal generation efficiency for each facility through three frameworks: 1) Preventive maintenance, 2) Rapid fault response, and 3) Proposals for various power generation equipment.

Preventative maintenance

Monitoring and expert-driven data analysis enable detection of equipment malfunctions and power generation anomalies at an early stage.

Rapid fult response

Ensuring prompt and effective responses to facility breakdowns and reductions in power generation, along with swift restoration through dependable cause analysis.

  • Reduced power generation of Power Conversion System (PCS) due to damage

    Reduced power generation of
    Power Conversion System (PCS)
    due to damage

    Ongoing monitoring and analysis revealed several PCSs that were not operating at peak efficiency. On-site technicians addressed the control system issue, and the PCSs then restored maximum power output.

  • Power output reduction due to equipment deficiencies (construction defects)

    (construction defects)

    Remote monitoring detected abnormal power generation, prompting an immediate alert to onsite workers. Upon inspection, a temperature anomaly was identified and addressed, successfully preventing a potential minor fire incident.

  • Significantly reduced power generation compared to previous year (equipment deficiency)

previous year (equipment deficiency)

Analysis and monitoring revealed a notable decline in power generation when compared to the previous year’s corresponding period. After addressing issues with the panels and construction defects, power generation was restored to normal levels.

each facility

To maximize power generation, we make proposals on equipment that is optimal for the specific conditions of the facility and its location.

  • Prevention of snow accumulation on panelsPrevention of snow accumulation on panels

    Prevention of snow accumulation on panels

    Implementing snow removal strategies for solar panels, which are often installed in mountainous or snowy regions, is crucial to prevent sunlight obstruction and to ensure that power generation remains at its peak range.

    Sun-tracking panel mounts

    Panel mounts that follow the sun’s movement enhance power generation by approximately 20-40% compared to standard mounts.

03Certified as an “Electrical Safety Corporation” by the Ministry of Economy,
Trade and Industry (METI)

GPD is certified as an “Electrical Safety Corporation” by METI. In accordance with the Electricity Business Act, we offer comprehensive support for all matters concerning electrical facilities of power plants. This includes creating optimal security management systems customized to our clients’ needs, conducting mandatory inspections, and providing round-the-clock emergency response services every day of the year.

What is an “Electrical Safety Corporation”?

It is a corporation that is authorized to undertake electrical safety management tasks for various types of electrical facilities. A significant benefit is that there’s no need to appoint, where one would typically be required, an electrical chief engineer for safety work when contracted out to a METI approved “Electrical Safety Corporation” such as GPD.

Future Business Prospects

Advancing the potential of our power plants within the framework
of the “Three Points of Safety”

Japan Green Power Development Corporation of Japan (GPD) is currently launching a number of new projects, including biomass research, an energy storage plant initiative, and SAF research. We will continue to foster all kinds of businesses to realize “local production for local consumption of electricity,” as laid out in our Island Power Generation® plan. These endeavors extend beyond our company, signaling the expansion of Japan’s energy sector and the rising trend in outsourcing facility maintenance.

As we anticipate this future, we will persist in enhancing our proficiency in facility maintenance and operations. All the while, we will strive to ensure the stable progress of our operations, keeping in mind the Three Points of Safety; safety of employees, safety of the neighborhood, and safety of power plants. We believe this approach will contribute to the advancement of our enterprise and the broader energy industry in Japan.
