Tokyo, Japan - July 13, 2015
Yokogawa Solution Service Corporation, a subsidiary of Yokogawa Electric Corporation that is responsible for the company's control business in Japan, announces that a community energy management system (CEMS) that it has built and delivered to the F-Grid Ohira, Miyagi Limited Liability Partnership (LLP)* is now fully operational. The LLP is headed by Toyota Motor Corporation. Over a two-year period, this system was developed by the LLP, built by Yokogawa, and field tested. Funding for the testing of this system, which was developed as part of a smart community project undertaken by the LLP was provided by the Japanese government.
This LLP's CEMS optimizes the use of electricity by balancing the supply of power from the LLP's own natural gas cogeneration and solar power facilities with the purchase of electricity from the local power utility, and efficiently controls the supply of electricity and heat to the members of the LLP. From each of these companies' facilities, the CEMS collects data on electricity and steam demand, and, based on electricity and gas tariffs, calculates how much power should be generated by the LLP's own power systems. In the aforementioned field testing of the CEMS (April 2013 to March 2015), the LLP members reduced their energy costs by 20%.
The LLP's CEMS has a function that can also predict the energy demand at individual plants by collecting data that is strongly correlated with energy demand. Based on these estimates, the CEMS can be used to plan the optimization of electricity and heat supply by, for example, adjusting the operation of the gas cogeneration system. The LLP members can also compare these demand estimates with actual results and use this to make adjustments that will save more energy.
The CEMS is connected with a backup power system and plug-in hybrid vehicles that can feed power to LLP members and the local community when there is a temporary interruption or shortfall in the supply of power from the grid. By encouraging plants to voluntarily participate in this electric power sharing scheme, the LLP has established a foundation for the full implementation of demand-response policies that will mandate such cooperation.
In the future, Japan's energy policy will require communities and plants to make adjustments in energy supply and demand. By leveraging the expertise gained from its participation in the development of this CEMS, Yokogawa will be able to contribute at the regional level in building a distributed energy infrastructure.
* Founded in February 2013 by Toyota Motor Corporation and other companies that have facilities at the Second North Sendai Central Industrial Area. Through its smart community initiative, the LLP provides electricity and heat (steam and hot water) to member companies; sells, leases, maintains, and manages equipment and facilities; and supplies emergency backup power electricity. The LLP operates a 7.8 MW gas-fired cogeneration system, a 740 kW solar power system, and a 50 kW backup power system. Through cooperation with the local community, the LLP aims to provide secure access to electric power. This LLP's smart community initiative is a first for an industrial complex in Japan.

The use of renewable energy protects the environment and takes both society and industry closer to the goal of achieving sustainability. However, compared to conventional energy sources, there are certain challenges that stand in the way of its rapid adoption, such as higher production costs and greater instability in the supply of power to the grid. As a leading company in the control and instrumentation business, Yokogawa has always striven to help its customers in various industries achieve stable operations and improve productivity in their plants. Based on our VigilantPlant concept for attaining operational excellence, we are providing solutions that pave the way to the use of renewable energy sources.
In the mid 1970s, Yokogawa entered the power business with the release of the EBS Electric Control System. Since then, Yokogawa has steadfastly continued with the development of our technologies and capabilities for providing the best services and solutions to our customers worldwide.
Yokogawa has operated the global power solutions network to play a more active role in the dynamic global power market. This has allowed closer teamwork within Yokogawa, bringing together our global resources and industry know-how.
