Launch of Sales of Gas Den Power, a Liquefied Petroleum Gas-Based AntiPower Outage Measure for Companies and Public Facilities
On Monday, August 3, 2020, TOKAI CORPORATION (Headquarters: Shizuoka City, Shizuoka Prefecture;
Representative Director and President: Katsuo Oguri; hereinafter the “Company”) will launch sales ofliquefied petroleum gas-based Gas Den Power, an anti-power outage measure, that is effective power
securement system as a BCP measure in the event of a power outage caused by natural disaster, etc.
1. Background to development of Gas Den Power
Since July 2019, the Company has been distributing OTS House (near-future home where one can live as
normal even in the event of power outage or water supply suspension caused by a disaster by achieving acomplete self-sufficiency for water and power) as per Figure 1 mainly in Shizuoka Prefecture. Recently, theCompany has been developing power supply system useful for BCP measures in a disaster particularly forsecuring power by leveraging OTS original large-capacity batteries contained in OTS House.*1Checking the power suspension periods in major disasters in recent years shows increasingly longer powersuspension periods to have occurred regardless of disaster category, as evidenced by a suspension of about
one week after large-scale earthquakes such as the Great East Japan Earthquake and the Kumamoto
Earthquake as well as a suspension of around one week after the West Japan Torrential Rain (the end of June2018). (From the Cabinet Office website page on disaster management)
To secure power over a long period of time as a BCP measure against such major natural disasters, it isessential to have equipment able to generate power even at the time of a power outage, in addition to largecapacity batteries. The Company has developed Gas Den Power, a power securement system that is effective
as a measure in the event of an extended period of a power outage by leveraging expertise accumulated
through the liquefied petroleum gas business, among its flagship service offerings, and by combining lowpressure liquefied petroleum gas power generator for disasters*2 and OTS original large-capacity battery.

Characteristics of Gas Den Power● Able to supply power up to 5 KVA over long hours
It is a system leveraging a power supply output of up to 5 KVA, a characteristic of OTS originalbattery.
Although it is effective to install a battery as a BCP measure for dealing with a power outage, thepower supply stops once the battery is used up. While power generator would be an effective meansfor securing power, a small one is low in power supply level (1.5 KVA or so), being unable toprovide power required on the business site in the event of a disaster. Although it is also possible toinstall a large power generator, you would run into challenges such as installation spot, price andfuel securement.
Gas Den Power can supply power up to 5 KVA by mutually complementing the characteristics ofbattery and small power generator, and power over long hours of at least 90 hours (for 11 days)*3 if
an average consumption power required on the business site in the event of a power outage is 1,500w.

If OTS original battery and battery capacity of 24 Kwh are combined and battery is 100% full. Number of days ifutilization is 8 hours a day● Use low-pressure power generator for disaster management
There are various ways for emergency power generation in the event of a power outage. Recentyears saw an option of generating power by using solar power generation panels, it is often difficult
to install such panels on the rooftop of company business buildings and existing facilities due toexternal factors such as constraint under a building agreement and the need for a relatively bigwork. Compared with this, a portable power generator used by the system has a benefit of being
easily adopted as constraints on installation are only a few. While power generator fuels comemainly in the form of gasoline, diesel and cassette cylinder, they have a disadvantage of being
difficult to store over a long period of time and get in the event of a disaster. Compared such power
generator, low-pressure liquefied petroleum gas power generator is superior in fuel storage
efficiency and security and can provide power easily in an emergency. You can continuously run aliquefied petroleum gas power generator used by Gas Den Power (maximum output of 1.5 KVA) for
as many as 74 hours or so with a liquefied petroleum gas cylinder (50 Kg).
● Power generation, power storage and power supply system original for the Company (patentpending [Japan Application No. 2020-121101])[Liquefied petroleum gas-based anti-power outage measure: Gas Den Power]
On July 15, 2020, the Company applied for patent for the system,*4 which is a system original forus.
