For practically 9 hours in the day during the v,inter months thereis a load of 15,000 For hours durinp; the day there is apnroximately10,000 being used and for the remaining 9 hours the full capacityof the station is needed. From the above figures it ;voi;ld seem that unitsof 5000 K.^V. capacity would be best. Two units then could carry the 10, load and the third unit could be pa^all^d for the 15,000
