Case Study: Intelligent Renewables (Smart Solar)

Japan's ORIX Mainstreams Renewables with Maintenance Transformation

How can AIoT and advanced analytics help mainstream renewables in Japan?

With an intelligent preventive maintenance strategy for 82 distributed utility-scale solar farms.

Japan’s largest solar asset manager transforms solar asset productivity.

“With Envision Digital’s end-to-end solution and expertise, OREM can provide total customer support – from proposals to implementation to maintenance, which in turn helps our customers optimize energy use and reduce costs.”

About OREM.

OREM’s Challenge.

ORIX Renewable Energy Management Corporation (OREM) is the subsidiary of ORIX Corporation (ORIX), a diversified financial services group headquartered in Japan. OREM runs the operation, management, and maintenance of power plants that use renewable energies such as solar power. 


With 1 GW of solar energy assets, including utility-scale, commercial and industrial, ORIX is the largest solar asset manager in Japan. It also develops and operates its own rapidly growing fleet of solar farms that currently generate 420 MW in utility, including Niigata Yotsugoya Power Plant (55.6 MW), Shiriuchi Mega Solar 20M Power Plant (24 MW), and Hirono-Cho Mega Solar Photovoltaic (PV) Plant (24.3 MW). ORIX’s OR Yamaguchi Mine Solar Power Plant (56.4 MW) is scheduled to commence operations in October 2021.

To contribute to Japan’s national goal of increasing its renewables mix to 24% by 2030, OREM wanted to implement innovative technology that can further increase the productivity of its solar assets.

What OREM is Working Towards.
Envision Digital helps OREM contribute to sustainability agenda.

Power utility-scale solar farms with innovative digital capabilities.

Envision Digital will deploy EnOS™ AIoT platform – together with Ensight™ Solar, cloud-based advanced analytics, and Enlight™ Solar, remote monitoring capabilities – to OREM’s utility-scale solar farms across 82 sites in Japan.

Acquire insights into failure indicators and recommendations for corrective action.

Advanced analytics algorithms, which detects anomalies and predicts system underperformance while delivering smart remedial actions, will help OREM preemptively maintain the long-term efficiency and health of its PV assets.

Optimize power generation capacity with better visualization capabilities.

With 360-degree view into OREM diverse portfolio of distributed assets, OREM’s operations and maintenance (O&M) teams will be able to better visualize power generation conditions to optimize production capacity.

Respond faster in malfunctions with remote operational monitoring.

Enlight™ Solar’s real-time remote operational monitoring capabilities across distributed PV sites also help OREM’s O&M team rapidly respond in malfunctions to reduce downtime and maximize power generation capacity.
