Yanmar Co., Ltd.

Hitachi, Ltd. and Yanmar Energy System Co., Ltd. (YES) have formed a partnership for the development of distributed generation systems that are able to power small-to-midsize factories, public facilities and businesses.

The new system, which was first released on June 2, utilizes YES’ micro-cogeneration technology and Hitachi’s newly-developed micro grid control system. The system allows for more efficient energy control and generation, and is effective in lowering energy costs and CO2 emissions during peak usage times. The system also contributes to businesses’ continuity plans by acting as a self-powered system during power outages.

The demand for solutions that save energy and prevent power failures has risen since the 2011 Tohoku earthquake. Revised laws regarding energy efficiency measures also positively value organizations actively involved in reducing energy consumption during peak times by using in-house power generation and storage batteries in distributed generation schemes. Because of this, there is a growing movement among factories, public facilities and businesses for the introduction of distributed generation schemes that utilize gas engines, solar and wind power, storage batteries, etc. In response to this, Hitachi and YES have worked together to create a basic structure for dispersed generation complete with control mechanisms.

YES has been selling micro-cogeneration units since 1998. These units reduce heat loss by utilizing the residual heat produced by gas engine generators to provide energy for water heating and climate control. The micro-cogeneration system is fitted with a highly efficient engine that employs gas heat pump air-conditioning. It boasts a simplified installation process and a long maintenance interval of 10,000 hours. Over 6,800 units have been installed to date in various establishments, including health and welfare facilities, factories, restaurants and more, allowing YES to secure a large share of the small-size gas engine market in Japan.

Hitachi has worked for several decades to create a smart grid that offers power from various sources such as solar, wind and battery. Its new micro grid control system is the product of this technological research for a grid control system that commands entire distributed generation energy systems.

As the market for dispersed generation energy systems continues to grow, both Hitachi and YES will continue to work together and utilize each company’s strengths to expand the sales of this new system package.
