O&M（Operation & Maintenance）
O&M services that provide comprehensive support for the stable operation of power plants.
Solar power generation isn’t a “set it and forget it” kind of project.
Maximize long-term profits for over 20 years with planned maintenance and remote monitoring.
Why is O&M necessary?
Proper maintenance and inspection are legal obligations and are a critical issue that significantly impacts the profitability of power generation operations.
Mandatory under the revised FIT Act
Under the revised FIT law, proper maintenance and inspection are now mandatory for all solar power generation facilities.
Failure to perform maintenance may result in the loss of FIT certification and the risk of fines.
Maximize profitability
We prevent panel deterioration, malfunctions, and power generation reductions caused by weeds and dirt.
Regular inspections and emergency response minimize lost opportunities for selling electricity.
Maintain asset value
High-quality maintenance by expert technicians extends the lifespan of equipment, protecting the asset value of power plants and securing favorable terms for future sales.
Risk management and safety
Early detection of hot spots and insulation degradation prevents serious accidents such as fires and electric shocks, protecting against business disruption risks and loss of social credibility.
O&M Service Lineup
We support long-term stable operation through a three-pronged approach: “monitoring and response,” “periodic inspections,” and “repair and replacement.”
24-hour remote monitoring
Power generation and system abnormalities are constantly monitored. In the event of an abnormality, an immediate alert is issued for a swift response.
Regular inspection and diagnosis
Statutory inspection based on JPEA guidelines. Checks include electrical systems, panel appearance, and mounting structure corrosion.
Repair and replacement service
Speedy recovery in emergencies such as power conditioner failures or panel replacements. Minimizing losses from selling electricity.
Environmental maintenance management
We eliminate factors that hinder power generation through weed control, panel cleaning, snow removal, and security measures.
Detailed reporting
A dedicated report clearly visualizes inspection results, changes over time, and improvement suggestions.
EL inspection and infrared diagnosis
High-precision inspections detect internal cracks and hot spots, enabling thorough preventative maintenance.

High level of trust and track record
O&M services that support the stable operation of energy storage plants in the long term.
Grid-based battery storage systems are not a “set it and forget it” project. Proper operation and maintenance are crucial for profitability.
We provide comprehensive support to maximize the value of your energy storage assets, 24 hours a day, 365 days a year.
Why is O&M necessary for grid-based battery storage systems?
With the large-scale introduction of renewable energy, battery storage is essential for stabilizing the power grid. However, proper operation and maintenance, including fire risks and compliance with legal regulations, are key to the success of the project.
Responding to the revised Electricity Business Act
Grid-mounted battery storage systems are classified as a “power generation business,” and their operation and management are mandated under the Electricity Business Act. We ensure that all legal requirements are met, from the submission of the basic plan to maintaining compliance with technical standards and periodic reporting.
Maximizing profitability
Revenue from battery storage systems is directly linked to market trading (arbitrage and supply-demand adjustment markets). Proper degradation management and maintaining high operating rates maximize FIT/FIP revenue and increase the likelihood of investment recovery.
Compliance with fire safety regulations and ensuring safety.
Lithium-ion batteries are classified as hazardous materials under the Fire Service Act. Appropriate safety measures, statutory inspections, and the placement of qualified hazardous materials handlers are essential.
Deterioration management/life extension
Preventive maintenance through battery cell condition monitoring (SOH/SOC) to address aging degradation. This extends battery life and minimizes replacement and disposal costs.
O&M Services: 5 Core Functions
This solution covers all the most important functions for the operation and maintenance of grid-connected battery storage systems, providing a one-stop solution.
