Grid-Scale Battery Energy Storage Systems worked example

Rack Assembly Takt with net available assembly time of 1,100 min / shift: a worked example

Push net available assembly time up to 1,100 min / shift and the picture changes. This example computes every intermediate figure at that operating point. Use it to set line pace, staffing, and station balance for Grid-Scale Battery Energy Storage Systems whenever demand or available time changes.

The inputs for this scenario

  • Net available assembly time: 1,100 min / shift (raised for this scenario; the documented default is 450)
  • Battery rack demand: 60 units / shift (unchanged)
  • Shifts per day: 2 shifts (unchanged)

Working through the calculation

  • Applying the documented formula (Takt time = net available production time × 60 ÷ customer demand) to the inputs above produces each figure below.
  • At this operating point the engine returns 1,100 sec / unit for takt time, the number this scenario is built around.
  • At this operating point the engine returns 3.27 units / hr for required rate.
  • At this operating point the engine returns 2,200 min for available time / day.
  • At this operating point the engine returns 120 units for demand / day.

How this compares with the baseline

  • Against the tool's baseline example, where net available assembly time sits at 450 min / shift and the headline result is 450 sec / unit, this scenario comes in 144% above the baseline at 1,100 sec / unit.
  • It computes takt time in seconds per rack from net available time and demand, and the required output rate in racks per hour. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close it.

Results at a glance

  • Takt time: 1,100 sec / unit (headline result)
  • Required rate: 3.27 units / hr
  • Available time / day: 2,200 min
  • Demand / day: 120 units
