EGS Co., Ltd.'s "Computer Breaker" Surpasses 4,000 Installations Nationwide

EGS Co., Ltd. (Headquarters: Shibuya-ku, Tokyo; Representative: Takeharu Nozaki) provides a power cost reduction solution using "Computer Breakers" aimed at reducing the basic charges of electricity bills. As of March 20, the number of installations nationwide has surpassed 4,000 facilities. The solution is being adopted by a wide range of industries using low-voltage power contracts, including restaurants, retail stores, convenience stores, coin laundries, and nursing care facilities.

・Increasing demand for power cost reviews due to soaring electricity prices In recent years, electricity prices in Japan have continued to trend upward against the backdrop of soaring fuel costs and changes in the energy market. TEPCO implemented an average electricity price hike of approximately 15.9% in June 2023, and the burden of power costs has continued to increase since then due to factors such as rising renewable energy surcharges. Electricity bills are a significant fixed cost for companies and stores, representing a major management challenge, especially for businesses with high power consumption. Furthermore, against the backdrop of soaring electricity prices, consultations from companies and stores regarding power cost reviews are also on the rise.

・Structural problems with Japanese electricity rates—The reason electricity bills don't go down even if usage is reduced is the "Basic Charge" It is often thought that electricity bills are generally determined by "usage," but in reality, the basic charge determined by the contract capacity accounts for a large proportion. Since contract capacity is determined based on the facility's maximum power (peak demand), in many cases, the basic charge will not decrease unless the contract capacity changes, even if electricity usage is saved. In other words, there is a structural problem where electricity bills do not go down as much as expected even if electricity is saved. Furthermore, in recent years, the power cost burden on companies and stores has been increasing year by year due to: ・Rising electricity unit prices ・Rising basic charge unit prices ・Abolition of basic charge discount systems Against this background, attention is being focused on electricity bill measures that involve reviewing the contract capacity itself.

・Up to 65% reduction by reviewing contract capacity The Computer Breaker provided by EGS Co., Ltd. is a mechanism that enables a review of contract capacity by controlling power usage status to suppress maximum power. This can lead to a reduction in the basic charge of electricity bills, and in actual installation cases, there are instances where a "maximum 65% reduction in contract capacity" was achieved.

・Case Study—Annual cost reduction of 400,000 yen One store reviewed its contract capacity by introducing a Computer Breaker and achieved the following reductions: Contract capacity before introduction: 40kW ↓ Contract capacity after introduction: 10kW

【Result】 Reduced capacity: 30kW Low-voltage power basic charge: 1,098.05 yen / kW Therefore, the monthly reduction amount is 32,941.5 yen, which could lead to a power cost reduction of nearly 400,000 yen per year.
