There was an article in the Evening Standard last night about the bus

I read that article too, according to this press release (link below) from
2016 the charging power comes from the grid. Not a local generator.

I suspected it would be something like that. Installing a generator would seem
to defeat the point of having electric buses.

"They also needed 2.5 megawatts of electricity to recharge the buses
overnight — although the use of smart monitoring means they never reach
that full load.

In comes 11,000 volts to two new substations on the site, which is then
dropped down to 400 volts and sent via two routes to the various
charging points around the depot. Four fast chargers at 800 volts are
also available if needed."
