I was discussing this opportunity with Dennis Bezuidenhout this morning.
It is a large project and I propose to slice it into several steps and to only offer a conceptual design (incl cost estimate, timeline etc) at this stage. I also propose to offer a diagnostic of the existing electrical systems/infrastructure with a view of potential future loads to be added (eg blowmoulding, more manufacturing capacities etc), rather than focusing on the substation only.
Please feel free to call Dennis today who is briefed on this opportunity. I will be out of office today from 9AM to about midday (Bangkok time) but happy to catch up later today or Monday.
