A logistics yard in Aichi has taken delivery of a 2,742 kWh battery beside 858 kW of roof solar - operations are scheduled for February 2027, and the yen are blank
On 27 October 2026 PowerX said it has delivered one Mega Power 2700A battery to Miyoshi Logistics Center III in Aichi, with Toyotsu Energy. Roof solar on that center is 858 kW. Nominal battery capacity is 2,742 kWh and rated capacity is 2,468 kWh. The converter is 650 kW. Private lines share power with three other sites in the same yard. Operations are scheduled for February 2027. The page plans self-consumption near 97% and marks about 472 tons of CO2 and about a 30% cut in maximum demand as simulation estimates. No yen figure is printed.
Four logistics buildings in one yard are set up to share one roof of solar, with a battery to hold the surplus. The box is on site. The switch-on date is later. The yen are not on the page.
On 27 October 2026 PowerX said it has delivered one Mega Power 2700A battery to Miyoshi Logistics Center III in Miyoshi City, Aichi, working with Toyotsu Energy. The site belongs to Toyotsu Logistics Service. The English page says it is a translation of the Japanese release, and that the Japanese original prevails if the two differ. The figures below are the ones printed on the English page.
The hardware, on that page. One 20-foot container. Lithium iron phosphate cells. Made in Tamano City, Okayama. Nominal capacity 2,742 kWh. Rated capacity 2,468 kWh. 2,742 minus 2,468 is 274, by our arithmetic. The page does not print that gap as a percentage. The converter output is 650 kW. Roof solar on Miyoshi Logistics Center III is 858 kW. The page does not explain why the converter is smaller than the array. Nominal energy divided by converter output is 4.218 hours to three decimal places, by our arithmetic. Rated energy divided by the same output is 3.797 hours to three decimal places. The page does not print either duration.
The household line. The page says 2,742 kWh is equivalent to the daily electricity use of approximately 260 average Japanese households. It does not print the household figure used to get to 260.
Who takes the power. Private lines carry it to Miyoshi Logistics Center, Miyoshi Logistics Center II, and a Toyotsu Newpack facility. All four sit in SC Village, a Toyota Tsusho Group area. Private lines are wires on the site, so the power can move between buildings without a sale through the utility. Generation, demand and the battery are run by an energy management system. The page names the system and does not print its price.
The simulation lines. In a setup where the solar is used only in the building it sits on, the page says more than half of the generation was expected to go unused. With sharing and the battery, the project plans to self-consume approximately 97% of the electricity generated. The page then says this is expected to cut CO2 by approximately 472 tons a year and to curb maximum demand by around 30% through peak shaving. A footnote on that sentence calls the CO2 and demand figures estimates based on deployment simulations. Peak shaving here means cutting the highest spike of power the site draws. The page does not print a tariff for that spike.
The shortfall. Any electricity still missing is bought through a renewable supply scheme from Toyotsu Energy. The page says the center's electricity use is then effectively 100% renewable. It does not print the price of that supply.
The subsidy. The project has been selected for a Ministry of the Environment program funded in the fiscal 2024 supplementary budget. The English page prints the program's full name. The name covers faster renewable uptake by private companies, and models for sharing power between buildings. The page does not print a yen amount for that selection.
Dates that sit on different lines. Operations are scheduled for February 2027. PowerX says revenue from the project described in the release is expected to be recorded in the fiscal year ending December 2026. The page does not explain the gap. The February date is the scheduled start of operations. The December 2026 line is the supplier's accounting note. It is not a customer bill.
Outage. If the center is cut off from the grid, the solar and the battery supply an evacuation area inside the center. The page does not print how many hours that supply lasts.
The fill. Surplus solar goes into the battery and comes out when generation is low. The page does not print a wholesale price for charging the battery from the grid, and it does not print a comparison with a gas generator. A battery holds only what solar or the grid puts in. On this page the fill that is described is surplus from the roof.
Analogy: one tank for four sheds, filled from one roof. The tank is in the yard. The tap is scheduled for February 2027. The price of the water is not on the page.
Good: A public delivery date, a named logistics site, a solar size, two battery energy figures, a converter size, four named sites on private lines, a subsidy program on the page, and a footnote that marks the CO2 and demand lines as simulations.
Bad: No yen for the battery, the solar, the sharing lines, or the subsidy. No customer tariff. Operations are scheduled for February 2027, so delivery is not switch-on. The 97% line is a plan. The page does not print a duration, even with energy and power both on it.
Ugly: Reading 97%, 472 tons, or 30% as a metered result. Treating the December 2026 revenue line as the logistics firm's bill. Dividing 2,742 kWh by 858 kW and calling that the battery's hours. Ignoring the rated 2,468 kWh and using only the nominal figure. Pasting 260 households onto a workplace payback.
Soft next step: if a quote borrows the 97% line, that figure is a plan on the page, and the yen are not on it.
Source: PowerX, 27 Oct 2026 - delivery of a Mega Power 2700A battery to Toyotsu Logistics Service's Miyoshi Logistics Center III. Primary for the 27 October 2026 date, delivery of one Mega Power 2700A unit with Toyotsu Energy to Miyoshi Logistics Center III in Miyoshi City, Aichi, the page as an English translation whose Japanese original prevails if they differ, one 20-foot container of lithium iron phosphate cells made in Tamano City, Okayama, nominal capacity 2,742 kWh, rated capacity 2,468 kWh, converter output 650 kW, rooftop solar of 858 kW, an equivalence to the daily use of approximately 260 average Japanese households, private-line sharing with Miyoshi Logistics Center, Miyoshi Logistics Center II and a Toyotsu Newpack facility inside SC Village of the Toyota Tsusho Group, an energy management system, a plan to self-consume approximately 97%, an expectation that more than half the generation would go unused if the solar stayed in one building, approximately 472 tons of CO2 a year and around a 30% cut in maximum demand through peak shaving with a footnote that those figures are estimates from deployment simulations, shortfall power bought through Toyotsu Energy's renewable supply so the center's use is described as effectively 100% renewable, selection for a Ministry of the Environment program in the fiscal 2024 supplementary budget, operations scheduled for February 2027, supplier revenue expected in the fiscal year ending December 2026, and backup supply to an evacuation area in an outage. The page does not print a yen price, a customer tariff, a subsidy amount, a duration in hours, the household kilowatt-hour used for the 260 line, how long the outage supply lasts, or a wholesale price for charging from the grid. 2,742 minus 2,468 equals 274, 2,742 divided by 650 equals 4.218 to three decimal places, and 2,468 divided by 650 equals 3.797 to three decimal places, are our arithmetic. The page does not print those figures.
