In the Kingdom of Cambodia, MinebeaMitsumi committed to a High-efficiency LED Streetlight Implementation Project, working with Paradox Engineering and Iwasaki Electric. The project was selected for adoption in June 2015 as the first to be conducted in Cambodia under the Ministry of the Environment of Japan, using a Joint Crediting Mechanism (JCM). In February 2017 MinebeaMitsumi was awarded the Cambodian Environment Minister’s Prize for this installation.

About 8,000 streetlights were replaced with LED luminaires and connected to a wireless network to allow remote monitoring and control, covering four different locations in Phnom Penh City, Siem Reap City and Angkor Wat ruins area.

A reduction of about 70% of Green House Gas (GHG) emissions was gained in Phase 1, comparing the new solution with conventional High Intensity Discharge (HID) lighting providing the same level of brightness. About 55% of GHG emissions saving is accountable to LED technologies, while an additional 15% to the wireless control system. Energy saving will increase to 80% in Phase 2 thanks to the implementation of advanced LED streetlights further cutting energy consumption, and the optimization of dimming patterns.

Positive results were also achieved in terms of grid safety. Each node now continuously monitors grid voltage variations, supporting the electricity supplier in designing and operating the grid according to visualized peaks and drops. This contributes to energy optimizations and minimizes the risk of blackouts.

Working for a smarter Cambodia, MinebeaMitsumi is endeavouring to construct a comprehensive network platform to monitor and manage different urban applications, thus integrating in the same infrastructure devices such as parking sensors, electricity meters, surveillance cameras, etc. In combining these functions, MinebeaMitsumi is undertaking the challenge of developing evolved devices which are not just lights, but lighting equipment with various added values such as energy-saving, improved safety, improved convenience of city life, etc.

MinebeaMitsumi will continue to forge ahead with developing in Cambodia the most advanced Smart City showcase in the world, as well as concentrating the Group’s latest technology to contribute to environmental measures and reduce electricity use in the country.
