The customer’s clock and the storage specification
I would begin with a fictional 10 MW and 20 MWh storage proposal, asking participants to name the customer task before discussing the apparent opportunity. Five operating profiles need a two-hour peak window; three need six hours. The exercise would explore the cost of keeping all eight beneath one family name and the alternative of funding a narrower feasibility programme. I would explain why the nominal ratio does not itself establish actual delivered duration, leaving engineering evaluation visible rather than hiding it inside the product decision. Participants would practise writing a short scope statement that retains the excluded use cases and the next responsible owner. No real site specification or commercial bid would be requested. This proposed session has no prior delivery or audience claim. Its aim would be to make a product decision assessable without turning an equipment rating into a larger service promise. The closing discussion would consider how the same distinction survives when a detailed development brief becomes a concise executive or board paper.
