Toyota Supplier JTEKT Installs Large Solar Carport In Japan Under 20-Year PPA To Boost Clean Energy Transition

JTEKT Corporation, a key supplier to the Toyota Group, has taken an important step toward cleaner energy by commissioning a large solar carport installation at its Tadotsu manufacturing plant in Kagawa Prefecture, Japan. The project has been developed through a 20-year Power Purchase Agreement (PPA) with renewable energy developer Peak Energy and is considered one of the largest onsite solar carport systems installed at an industrial facility in Japan.

The solar carport is expected to generate about 2,500 MWh of electricity annually. This amount of power is roughly equal to the yearly electricity consumption of several hundred average households. By installing solar panels above the plant’s parking spaces, the company is using existing infrastructure to produce renewable energy without needing additional land. The design also offers practical benefits for employees by providing shaded parking areas while supporting the company’s sustainability objectives.

Under the Power Purchase Agreement model, Peak Energy financed, installed, and will continue to operate and maintain the solar system. JTEKT will purchase the electricity generated by the project over the next two decades at an agreed rate. This approach allows the company to adopt renewable energy without making large upfront capital investments. It also ensures more predictable energy costs in the long term, which can help industrial manufacturers manage operational expenses.

The project forms part of JTEKT’s wider Carbon Neutral Strategy, which focuses on reducing greenhouse gas emissions across its global operations. As an important supplier within the automotive manufacturing ecosystem, the company’s transition toward renewable energy supports broader sustainability efforts taking place across the automotive industry. Manufacturers are increasingly being encouraged to reduce emissions not only from vehicles but also from the production process and supply chains.

The solar installation at the Tadotsu plant is expected to cut approximately 1,200 tons of carbon dioxide emissions each year. This reduction contributes to local environmental goals within Kagawa Prefecture and demonstrates how industrial facilities can adopt renewable energy solutions even in regions where land availability is limited.

Japan has faced challenges in developing large ground-mounted solar farms due to limited available land and high population density. As a result, onsite solutions such as rooftop solar systems and solar carports are gaining popularity among corporations looking to increase renewable energy use while making efficient use of existing spaces. The partnership between JTEKT and Peak Energy highlights how collaboration between industrial companies and renewable energy developers can accelerate the transition toward sustainable operations. By committing to a long-term renewable energy agreement, the Tadotsu plant will rely on solar power for a portion of its electricity needs for the next 20 years, supporting the wider environmental commitments of both JTEKT and the Toyota Group.
