Tokyo, June 24, 2019 - Mitsubishi Heavy Industries Engine & Turbocharger, Ltd. (MHIET), a Group company of Mitsubishi Heavy Industries, Ltd. (MHI), has developed a “Triple Hybrid” stand-alone power supply system that combines renewable energy such as solar power with a reciprocating engine generator and storage battery, allowing for optimal stabilization control. The system's main advantage is its ability to stabilize the volatile output of renewable energy by combining three types of power sources, allowing for a high efficiency, low-cost power supply provided by an environmentally-friendly, multi-purpose distributed generation system. The Triple Hybrid Power Station demonstration facility, combining solar power generation equipment, storage batteries, and an engine generating plant, has been put into operation at MHIET's Plant, where the head office is located. The power generating system has been named EBLOX, and the control system COORDY. These systems establish a structure that allows MHIET to offer solutions to meet diverse power supply needs.
