ABB provide combiner boxes to one of the nation’s largest mega solar plants

2015-09-03 - ABB’s resin combiner boxes, PVmax contributes to the development of the Setouchi region by supporting efficient construction, safe and sustainable operation of mega solar plant.

Tokyo, Japan, September 3, 2015 – ABB, the leading power and automation technology group, has got an order of combiner boxes for one of Japan’s largest solar power plant projects in Okayama Prefecture, Japan. The project, funded with market-leading investment by GE Energy Financial Services, Toyo Engineering, Chudenko and Kuni Umi Asset Management, and will be an around 230 megawatt facility to boost utilization of renewable energy in the Setouchi region, the coastal area around Setonaikai Inland Sea, west Japan. ABB received the order from Toyo Engineering, which is responsible for EPC of the project.

The project was chosen among the public proposals to utilize the former Kinkai salt field by Setouchi-city, in view of benefit to the whole city. Toyo Engineering started the construction of the solar photovoltaic plant beginning in October 2014. The project, with approximately at USD 0.9 billion scale is also designed with environmental-responsibility and safety.

The ABB’s combiner box, PVmax* fits very well to this concept. It configures ABB’s leading edge low voltage products, which is in Gemini resin enclosure, which does not need repainting over 20 years, and can be recycled in full. With a series of ABB’s low voltage products, PVmax fulfills the requirements of the customer to ensure secure and sustainable plant operation. Also, light weight, easy-to-handle feature help increase efficiency in construction phase. In Japan, metal enclosure used to be conventional before the debut of Gemini. Therefore, Gemini significantly slashed the burden of site workers, and consequently contributed to improve project construction period and cost.

“We are pleased that PVmax was chosen to support one of the largest mega solar power plants in Japan,” said Tsuyoshi Yoshida, Local Division Manager, Low Voltage Products Division, ABB in Japan. “ABB is a pioneer that implemented the first IEC based, DC1000V mega solar power plant in Japan. We believe this as a crucial benefit to Japanese customers and market. ABB will continue to lead the market with its unique and innovative technologies to push the boundaries and bring our customers to the Next Level.”, he added.

ABB will deliver approximately 5,000 PVmax combiner boxes for the project. ABB’s world-class manufacturing capacity with quality, as well as its leading edge technology in DC1000V and above help one of the nation’s largest solar projects to success. The project is expected to reach commercial operations in the second quarter of 2019, and planned to sell its power to Chugoku Electric Power Company for 20 years under Japan’s renewable energy fee-in-tariff regime.
