The generating plant is all placed in a
conveniently situated building within
or without the District to be Lighted.
Convenient Sub- or Storage-Stations
are selected throughout this District,
and contain sufficient Accumulators to
supply the maximum demand.
The Batteries in each of these
Storage-Stations are recharged
in series, _one-half at a time_,
throughout the System during the period
of minimum demand, and by the evening
are all full and ready to cope with the
heavy night work.
The whole of the charging, discharging,
and regulating apparatus is worked
automatically.
