1. The challenge
Three sheds, 212,000 sq ft of corrugated roof, and six to nine hours of monthly load-shedding that stopped dyeing lines mid-batch. Diesel backup was costing more per unit than the grid.

2. Our approach
Structural survey of every purlin before design. East-west module layout to stay inside wind-load limits, a 1 MWh LFP bay for the dyeing lines, and zero-export control so the plant never back-feeds the feeder.
3. The result
The dyeing lines now ride through outages on battery, diesel runtime is down 78%, and the plant's monthly grid bill fell by 31% in the first full quarter.

We stopped losing batches to load-shedding in the first month. The savings were the second surprise.
