Visualization of power generation efficiency and productivity for power plants
Launch of report service for mega solar power plants

Mar 11, 2022

TOKYO, Japan - March 11, 2022 - ORIX Renewable Energy Management Corporation (“OREM”) announced that it will commence a turnaround support service, evaluating and analyzing the operational status of large-scale (mega) solar power plants from a third-party perspective and proposing effective management strategies.

As the movement toward decarbonization accelerates, the development of new mega solar power plants is faced with the challenge of securing new installation capacity due to the limited availability of suitable sites*1. In contrast, interest in mega solar power plants is increasing among investors and others, and sales transactions in the secondary market are increasing*2.
At power generation facilities where OREM has carried out its solar diagnostic services—covering a total of approximately 2 GWp—the average yearly deterioration rate has been approximately 1%, which is short of the guaranteed panel output provided by panel manufacturers (deterioration rate of 0.5% per year). In addition, the number of accidents at power generation facilities, such as inadequate safety systems, is increasing year by year*3, and unless proper operation and maintenance is carried out, there is a risk of the future value of solar energy being impaired.

The turnaround support service combines fieldwork conducted by highly experienced engineers with data analysis using artificial intelligence (AI) and other state-of-the-art digital technologies to provide reports on management strategies for maximizing electricity sales revenue. The reports identify the cost effectiveness of operation and maintenance (O&M) and specific measures to prevent reductions in the performance of power generation facilities and minimize failure risks.
Cash flow projections associated with the sale of electricity are also evaluated and analyzed. Investors considering purchasing an operating power plant will be able to clearly ascertain actual and potential risks and potential involved in mega solar power plants.

Since its establishment in 2018, OREM has provided O&M for 84 mega solar power plants operated by ORIX Group, with a total power generation capacity of 436 MW, and since 2021, it has also been contracted to provide external services*4. By conducting O&M using AI and other advanced digital technologies, OREM is maximizing power generation, including improving PR value*5 by more than 4% in the first year of starting a contract. OREM is contributing to promoting the uptake of renewable energies by assessing conditions at each power plant and achieving highly efficient operations through optimal O&M.


ORIX Group will continue to expand its renewable energy power generation and asset management businesses, with the goal of growing the uptake of renewable energies worldwide.
