for the 200KW point - its tough to say honestly, 2-3 100-200 KVA units are typically used for powering the main site office for construction (this point only applies to construction - which seems to be the area they are currently targeting, i accept 200KW would be a larger market for the world as a whole) - those offices are for 15-25 office staff and typically have welfare for 20-40 site workers (this would be a typical highways improvement scheme / bridge replacement scheme as an example).
in most of the projects i have worked on however the 100KVA units are far more prevalent - because they are more mobile and its not Atypical to have satellite units away from the main compound where additional welfare provision is needed along with power tools and task lighting.
that said for the 10KW power tower there is actually a huge quantity market or them in construction(though obviously the per unit cost is lower so it would be nice to know the figures AFC are charging)
just not in the form they are currently marketing this - it would be far better for them to tie in with company's like portacabin, Sunbelt, speedy e.c.t to try and get them fitted into the containerized welfare facility's for 5-12 people as it isn't uncommon for there to be a large number of these on sites especially ones such as HS2 where the construction area is rather wide spread (you don't want workers traveling for 20 mins each way before and after their break as for a team of 30 that's 12 man hours lost a day). and assuming the power tower is quieter this would be brilliant for the workers and noise impact on local community (you have a headache after sitting in one of the cabins for 20 mins or so with the Genny running as they are quite loud)
another use for this would be temp charging facility for EV's - i am a yet to meet anyone in the construction industry who is based on site for any more than 20% of their time with an EV, myself included as personally i drive 20,000+ miles a year. so a site visit 150 miles away for an 8 hour meeting becomes a much longer day or multiple days when you have to plan in a few hours of charging too, ultimately meaning more time spent away and not with your loved ones (this is the number 1 burden of construction industry workers who aren't director level, some years i was based away in places so remote i only got 30 nights in my own bed in a year, with an EV that would have been none at all. and i am project engineer so there is less need for me to be on site than the operational staff)
if ample charging was available at the location of the site it would be less of a sticking point. likewise for the supervisor with an electric van, if he doesn't need to charge up on a night before getting back to the hotel where the 1-2 chargers provided are in use by those who finish work before 6pm - its less friction if facility is provided to charge at work while the vehicle is idle and they are busy with other thing
