POWER SUPPLY

SEPARATING KING’S WHARF FROM ARAPUNI STAND-BY PLANT In connection •with the separation of Arapuni power and the King’s Wharf supply a report was submitted to the Auckland Electric-Power Board yesterday by the general manager, Mr. R. H. Bartley. The report was the result of a discussion between Mr. Bartley and the district electrical engineer of the Public Works Department. “For the time being we should definitely separate King’s Wharf and Arapuni power supplies, except under very special circumstances when it may be necessary and desirable in the interests of this board to parallel the plants," said Mr. R. H. Bartley. “These special circumstances may arise only on account of exceptional happenings with either plant. The arrangement means that we shall place, approximately 6,000 to S.OOO kilowatts on the Arapuni supply and King’s Wharf station will take care of the balance of, approximately, 20,000 kilowatts. This is the most convenient and simplest division for us to make and, in the event of a failure by either plant, the trouble

! will be confined to separate areas, j This arrangement will allow us to | I keep sufficient plant in operation and j { enable the steam statioiy to work j 1 more efficiently. ! “In the event of a failure of the ! hydro plant a certain time must still j elapse before the additional loading • could be picked up from King’s Wharf, but only sufficient time to enable the board to run np extra plant and make adjustments in connection with steaming. “I am advised, although not officially, that the second unit at Arapuni should be ready for operation in about two months from date and I would recommend that the whole position in connection with our operation be reviewed about that time,” Mr. Bartley concluded. -The report was adopted.
