One of the limiting factors for electrifying bus fleets (apart from the additional cost of the buses themselves) is getting enough power to the depots from the grid. Each bus can take 100kW easily for a few hours, so a depot with 50 buses requires a 5MW connection, which is a lot if there isn't spare capacity on the grid near it. A short term problem for sure but it is causing enormous problems in London (grid is really streched even for new residential towers, so adding a multiMW connection for depots is not trivial whatsoever).
