Are you familiar with grid parity? In simple terms, "grid" means "power transmission network" and "parity" means "equality," referring to the point at which the generation (storage) cost of renewable energy and storage systems is equal to or lower than the cost of electricity from existing systems. This changes from year to year, but for example, figures like ¥60,000/kWh or ¥70,000/kWh are often mentioned recently... Naturally, due to the principle of thin profit margins and high sales volume, the pricing becomes most stringent for grid-scale storage systems that are easier for everyone to participate in (with an output of less than 2,000 kW and a capacity of 8 to 10 MWh). ...However... As mentioned in the title, our company offers a wide range of equipment that contributes to grid-scale storage systems as a complete ESS. We are fully aware that there are technical directions and factors that cannot be measured by price alone, depending on the manufacturer and model. For customers who are determined to lower costs and minimize initial expenses, we can surprisingly provide grid-scale storage batteries as mentioned in the title! Please feel free to consult with us!

Our main supplier, Taiwa Electric, has restocked the essential protection relay set for complete self-consumption/on-site PPA that we primarily use on rooftops! This set can be easily installed from the front without the hassle of cutting the panel and assembling it from the back, as was required with previous models. Additionally, it allows for the setting of C contacts, making installation and configuration on-site simple and exceptionally reliable, making it a popular model. When we use it for complete self-consumption projects, we rely on it almost 100%, and as usual, we have ordered a bit more than necessary, so if anyone needs it, please let us know. We will offer it at a friendly industry price. Our main business has shifted to "grid-connected battery storage," retrofitting battery systems for existing demand facilities, and retrofitting battery systems for FIP transfers, but we still receive quite a few requests for complete self-consumption/on-site PPA projects. After all, with rooftop installations, there are no renewable energy surcharges, fuel cost adjustments, or transmission costs! Complex energy designs with various vectors (directions of electric flow/arrows) are our specialty, so please feel free to consult with us.

There are numerous energy storage systems in the world, but without a doubt, the most dynamic right now is the "grid-connected battery." Our company is overwhelmingly receiving requests for design and applications related to this "grid-connected battery," but in response to that momentum, we are also seeing an increase in requests for energy storage systems designed for self-consumption within facilities. I believe there are many motivations for introducing energy storage systems, not only for very common BCP measures, peak shifting, and peak cutting, but also for considering the installation of ESS (energy storage systems) as an addition to existing PV projects, and furthermore, how to operate existing PV systems normally during unexpected power outages (which is called pseudo-grid connection). We can provide cost-effective proposals tailored to various applications from a wide range of options for any consultation. The advantage of "market-linked energy storage systems" is that, similar to our specialty in "grid-connected batteries," we can complete control within facilities without selling electricity. In other words, it involves charging when the electricity price in the market is low and discharging and supplying to the facility's load from the ESS when the price rises. It truly mimics the behavior of grid-connected batteries, doesn't it? (laughs) Please feel free to consult us about anything!

Right now in Japan, policies are being promoted to increase and expand both "renewable energy (mainly PV and then offshore wind power)" and "nuclear power generation," but this is actually impossible. The reason is that these two—"renewable energy (mainly PV)" and "nuclear power generation"—are like a seesaw; if one increases, the other decreases. In simple terms, it's because "renewable energy" is an unstable variable power source, while "nuclear power generation" is a stable power source. It seems that the current voices of the Japanese people are leaning towards the stable "nuclear power generation." But is it acceptable to leave behind something whose disposal method is not even known for tens of thousands of years to future children and grandchildren, while only we who live in the present enjoy that stability? This is where "grid-scale batteries," which can stabilize unstable "renewable energy," come into play. In South Australia, approximately 85% of the state's energy comes from "renewable energy," yet by distributing "grid-scale batteries," they support the state's energy infrastructure as a stable power source without any blackouts. By keeping the existing power grid as it is, grid-scale batteries can stylishly pass the baton to the next generation and save the planet.
