The value of a battery was forcibly demonstrated last winterduring the holidays. The maximum railway load amountedto 660 kw. If there had been no battery this would have beenbeyond the capacity of the water supply which was thenavailable for use. The average load was only 220 kw. Thebattery took the fluctuations so that the plant was operated FIG 6-VIEW OF STEAM TURBINE ROOM, SHOWING STEAMTURBINES, ROTARIES, ETC. with one wheel at full gate and one wheel at sixteenths fullgate. No exciters have been provided for this station for thepresent, as the engineers considered that in case all the direct-current machinery should be shut down, current for excitationcan be obtained from the battery.
