Market Overview

The domestic market size of plant O&M (operation & maintenance) services for manufacturing in FY2020 is estimated as 99.7% of the size of the previous year to attain 1,017,600 million yen. Demand for utility equipment operation and plant maintenance is increasing in the semiconductor industry, as the sector continues to expand production capacity. Nevertheless, because of the trend of reviewing capital investment plans and streamlining plants in the industries of steel, petroleum, and coal led by the economic recession in direct result of the COVID-19 pandemic, the market size shrunk slightly compared to FY2019.

Assuming that the sales of services for semiconductor industry continues stable growth, and projects postponed in FY2020 will be back on track, the market size of plant O&M services for manufacturing in FY2021 is projected to reach 1,025,700 million yen, 100.8% of the previous fiscal year.

Noteworthy Topics

Progress in Utilization of New Technologies in Plant O&M Services

Progress in developing products and services using new technologies including IoT has been witnessed among engineering companies and plant maintenance companies. For example, a service provider that succeeds in data utilization has developed the product/service that allows “analytics and forecasting based on data”.


A movement toward adopting subscription model as pricing is also seen for the purpose of reducing the strain on customers’ budget for introducing new technologies. In fact, there is a case in which VR (Virtual Reality) technology is used in the creation of contents for safety training. Such attempts may accelerate broader adoption of new technologies.

Future Outlook

The domestic plant O&M service market size for manufacturers is forecasted to attain 1,028,800 million yen by FY2022, and 1,031,900 million yen by FY2023. Since demand for O&M services is likely to rise among industries that are spotted to update equipment and/or reinforce production capacity, such as chemical industry, semiconductor industry, and pharmaceutical industry, the entire market is projected to grow moderately in the medium to long term.


From mid-2020s, as more companies start capital investments for carbon neutrality, demand for O&M service for facilities like captive consumption renewable power generation system is expected to expand.
