Mazda Motor Corporation is expanding its use of on-site power purchase agreements and battery energy storage systems across its facilities as part of its strategy to advance renewable energy integration. The latest installations focus on the Mazda KD Center and the Miyoshi Plant, utilizing solar power generation equipment provided by ORIX Corporation.

On-Site Solar Installations and Power Generation

At the Mazda KD Center, an on-site solar power installation is scheduled to begin power supply in November 2026. The facility features a solar panel capacity of 2.2 megawatts (MW) and an estimated first-year power generation of 2.6 gigawatt-hours (GWh). Toyo Kohan Co., Ltd. will utilize the environmental value associated with surplus electricity generated at this site.

At the Miyoshi Plant, which includes the Miyoshi Safety Testing Laboratory 3, solar power generation equipment with a capacity of 0.8 MW is scheduled to start supplying power in December 2026. The estimated first-year power generation for this site is 0.9 GWh.

Battery Energy Storage System Implementation

The Miyoshi Plant project incorporates a battery energy storage system known as the Mazda Battery Station Miyoshi. This system utilizes new automotive lithium-ion batteries to store excess solar power generated on-site. The stored energy allows Mazda to effectively utilize surplus solar power and reduce peak electricity demand at the facility.

Relevance for European Automotive Observers

These manufacturing and supply chain developments outline Mazda’s operational steps toward achieving carbon neutrality at its global manufacturing facilities by 2035. While the announcement focuses strictly on Japanese production and logistical sites, broader manufacturing decarbonization efforts directly influence the environmental metrics and supply chain footprints associated with automotive production globally.

Practical Takeaway

Mazda’s phased rollout of on-site solar PPAs and automotive battery storage highlights ongoing industrial investments in localized renewable generation and peak-demand reduction, with the Miyoshi and KD Center facilities scheduled to activate their new systems in late 2026.
