The solar power generation and storage batteries that are attracting attention with the full-scale operation of the emissions trading system.
In recent years, there has been a growing interest in decarbonization and GX, in addition to rising electricity costs and measures against power outages during disasters. The Ministry of Economy, Trade and Industry is promoting an emissions trading system targeting businesses with high CO₂ emissions, which is expected to be fully operational from the fiscal year 2026. While the direct targets are businesses of a certain scale or larger, this issue is also relevant for small businesses due to requests for decarbonization from trading partners and the need to address electricity costs. Amidst this, the utilization of solar power generation and storage batteries is gaining attention. By using electricity generated from solar power in-house and storing excess electricity in batteries, businesses can prepare for power outages and manage electricity costs. Juntechno Service Co., Ltd.'s Fukuoka Sales Office is accepting consultations on the introduction of storage batteries and solar power generation, primarily in the Fukuoka area. They provide easy-to-understand explanations in columns aimed at beginners about the basics of GX and its relationship with storage batteries.

Emergency power supply "storage batteries" for households and businesses to prepare for heavy rain and typhoons in Fukuoka's power outages and disaster response!
The Fukuoka area, along with the rest of Kyushu, faces serious risks of flooding and typhoons almost every year. In particular, August 2025 left significant flooding and landslide damage across various regions due to consecutive linear precipitation bands and Typhoon No. 12. When such unpredictable disasters occur, the loss of lifelines such as electricity can lead to catastrophic damage. To protect households and businesses from unforeseen circumstances, it is essential to prepare power sources as part of "Fukuoka Power Outage Measures." An effective solution is a system that can provide stable electricity even during disasters. Introducing storage batteries for disaster preparedness in Fukuoka is not only crucial for ensuring a safe living environment for households but also essential for business continuity planning (BCP measures using storage batteries) to keep corporate activities running. Securing emergency power sources at bases in Fukuoka for offices and factories is extremely important for business continuity. Shall we start preparing for disasters that can happen at any time? For inquiries about optimal capacity, installation space, and implementation costs, please feel free to contact our Fukuoka sales office. Our specialized staff will propose the best plan tailored to your needs.
