Aisin Thai Automotive Casting (Aisin Group) and Shizen Energy / Constant Energy execute a Corporate PPA to expand its current solar rooftop operations to 3.7MW


On November 11, 2021, Shizen Energy Inc. (“Shizen Energy”) and Constant Energy have executed a long-term Power Purchase Agreement with Aisin Thai Automotive Casting Co., Ltd, (“ATAC”) that will expand its existing 1MW solar rooftop to a total of 3.7MW. Aisin Thai Automotive Casting is a joint venture between AISIN CORPORATION(Japan) and Toyota Tsusho (Thailand) Co., Ltd. This solar rooftop project is located in Kabinburi Industrial Zone, in Prachinburi province.

After contract signing one year ago, the first 1MW plant is currently providing clean, cost-competitive renewable energy and enabling ATAC to reduce their average electricity cost while lowering their carbon footprint. This expansion will build on this success and multiply its benefits.

Both the initial project and the current expansion have been financed with debt from a THB 1.5 billion (approx. US$50 million) project finance green loan facility, one of the largest in Thailand to date for commercial and industrial (C&I) solar plants, provided by TMBThanachart Bank PCL.

Michiaki Okuda, Managing Director at Aisin Thai Automotive Casting commented: “We are delighted to expand our existing solar rooftop operations from 1 to 3.7 MW and continue out our successful partnership with Constant Energy/ Shizen Energy.  This development supports our goals of accelerating the installation of renewable energy globally. We are looking forward to building on this platform to expand the use of solar power to other factories of Aisin Group in the future.”

Rei Ushikubo, Country Manager at Shizen Energy added: “We are very pleased to execute a contract with Aisin Thai Automotive Casting. Despite Covid restrictions we have worked very closely together as a team over the last year to successful construct the first 1MW project and plan the current expansion. We are committed to our long-term relationship with ATAC and delighted that it has led to this second project. We hope to contribute to the Aisin Group’s “Low-Carbon society” as environmental target and RE transition.”

Franck Constant, President of Constant Energy commented: “We have been pleased and honored to have established a long-term partnership with a premier industrial house such as Aisin Thai Automotive Casting which is an affiliate of Aisin Group, a leading company for manufacturing components worldwide for automotive and to have developed their first solar rooftop project in Thailand. Today’s expansion of the project shows the success of the first stage and underlines ATAC’s commitment to a cleaner future. We look forward to supporting a combined reduction in CO2 emission and electricity cost through this solar power plant.”
