Industrial scale

Three costs, one system

An industrial site pays for electricity three times over. There is the unit rate, there is the demand charge set by your highest draw, and there is the cost of a shift lost to an outage. A rooftop array on its own addresses the first and does nothing for the other two.

Adding storage changes that. Discharging during peak tariff hours reduces what you pay per unit. Holding your peak below the threshold reduces the demand charge. Carrying the line through an outage protects the shift.

The PentaVault Citadel is built for this. 261 kWh per cabinet, 125 kW continuous, liquid cooled with a built-in dehumidifier and fire suppression, IP54 rated so outdoor placement is on the table. Cabinets scale in parallel to match the connected load.

Industrial tariffs charge for the highest half hour of demand across the whole month, not just for the units consumed. A battery discharging through those peaks lowers the recorded maximum demand, and that single number can move the bill more than the generation does.

Applications

Where industrial storage earns its cost

  • Peak shaving

    Discharge during the most expensive tariff hours and recharge when rates fall, so the same consumption costs less.

  • Demand charge management

    Hold the site peak below the billing threshold by covering short high-draw events from storage rather than from the grid.

  • Production continuity

    Carry the line through an outage so a shift is not lost and the restart sequence is not triggered.

  • Telecom and remote sites

    Replace ageing lead-acid banks with one sealed cabinet. Liquid cooling holds capacity in shelters above 45 degrees.

Questions industrial buyers ask

Is there an upper limit on system size?
No. Arrays are designed to the available roof or ground area and the connected load. Storage scales by adding Citadel cabinets in parallel, so capacity grows without redesigning the installation.
What data do you need before you can quote?
Interval data from the meter if it is available, otherwise twelve months of bills, the connected load, the tariff category, and a clear statement of which circuits must survive an outage. Anyone quoting an industrial system without that is guessing, and the guess is normally in their favour rather than yours.
Will the cabinet cope with our site temperature?
The Citadel is liquid cooled with a built-in dehumidifier and rated from minus 30 to 55 degrees. That is precisely why we specify liquid cooling rather than passive at this scale: a passive cabinet loses usable capacity through a Multan or Sialkot summer, which is when you need it most.
How does storage reduce the demand charge?
An industrial tariff bills the highest half hour of demand recorded across the whole month. The battery discharges through those peaks so the meter never records them. One badly timed simultaneous motor start can set a charge you then pay on every subsequent bill, which is why this line often moves more money than the generation does.
What about fire safety at this scale?
The Citadel carries perfluorohexanone plus aerosol suppression with physically separated electrical and hydraulic circuits, and the chemistry is LiFePO4 rather than a nickel based cell. Certification covers CE, UN38.3 and IEC 62619, and we will hand you the certificates with the issuing body and number so you can verify them yourself.
Do you handle the grid application?
Yes. Industrial connections involve considerably more documentation than a residential net billing application, and preparing and filing it is part of the engagement rather than an extra.
Can we phase the investment?
Commonly, yes. A frequent pattern is generation first, then storage once the load profile has been observed under the new arrangement for a few months. Designing for the second phase from the start costs almost nothing; retrofitting for it later costs a great deal.
What happens to production during installation?
Roof and civil work runs alongside production. The tie-in requires a planned shutdown, which is scheduled against your maintenance window rather than imposed. For sites that genuinely cannot stop, the switching is staged so that only part of the board is out at any moment.

Where to next

Ask for the three-part model before you ask for a price

Unit rate, maximum demand charge and continuity are three separate numbers on an industrial site. A proposal that counts only the first understates the case, and most do.
