GE Japan has installed a high-capacity energy storage system, a gas engine for cogeneration, and various LED lighting equipment at the “Future Disaster-Proof Factory Plan” — a pilot project being undertaken by Sekisui House’s Tohoku Factory — according to a recent press release.

The Sekisui House Tohoku Factory — a regional disaster prevention facility that Sekisui House built via a public-private partnership with Shikama City, in Miyagi Prefecture — is partly intended to demonstrate the effectiveness of reducing peak electricity usage through the use of energy storage.

The combination of a gas engine and a storage battery, for example, can apparently lower a factory’s energy contract by up to ~700 kilowatts (kW) at a time — which is roughy equivalent to the peak electricity requirements of 223 households in the area.

Other than reducing peak demand rates, the project also intends, obviously, to serve as an example of disaster preparedness. Once installation is complete, Sekisui House’s Tohoku Factory will have access to an integrated system featuring: a high-capacity energy storage system, a gas engine, and a solar power generator (720 kW output).


“Sekisui House is working together with Shikama City in Miyagi Prefecture and the regional administration through a private-public partnership that promotes regional disaster preparedness measures,” stated Sekisui House’s Tohoku Factory manager. “In order to realize the concept of a ‘Future Disaster-Proof Factory’ that is eco-friendly during normal times, durable during disasters, and safe and secure for both local communities and companies, GE’s solutions are the best. GE energy storage system was particularly attractive for this product since it has technological strength and reliability through its high capacity and very compact size that requires only half of the installation space when compared to a lead-acid battery with the same capacity.”

“From the bottom of our hearts, we are delighted that our energy storage system, gas engine, and LED lighting equipment were selected for such an advanced project by Sekisui House that aims to create a city that is resilient against disasters through the collaboration of both public and private entities in Miyagi Prefecture, a prefecture that GE is partnered with to create sustainable cities,” stated Akihiko Kumagai, President and CEO of GE Japan. “We will continue proposing the appropriate solutions to disaster prevention facilities across Japan in order to correspond to various situations that arise during both normal and disaster times.”

Here are the details on what exactly GE Japan has installed:

  1. High capacity energy storage system: 2 Megawatts per hour (MWh), 500 kW output. As this is a module battery storage solution with great expandability, the cabinet boasts a long battery life cycle, requires minimal maintenance, and does not require external cooling or heating facilities
  2. Cogeneration gas engine: VGF H24GSID / 225KW power output. The gas engine realized a total thermal efficiency of between 75% and 80% through the Waukesha gas engine that is usable with cogeneration operations, and simultaneously produces electricity and warm water. It boasts high environmental friendliness with NOx concentrations below 40 ppm and high performance for disaster situations through its prompt booting after blackouts.
  3. LED lighting equipment: 491 units inside factory, 130 units inside office. LED lighting equipment promotes superior energy saving performance and eco-friendliness by conserving 70% of the factory’s energy. In addition to the office, cafeteria, and guestrooms, GE also installed solar LED street lights throughout the factory grounds.
