COLERIDGE POWER.

MORE GENERATING EQUIPMENT. IMPROVING THE WATER STORAGE (Per Press Association.) CHRISTCHURCH, This Day. Specifications have been prepared and tenders have been called for the generating unit which will complete the present capacity of the Lake Coleridge power station. Like each of the two most recently installed generating units, the new unit will have a capacity of 7500 k.w. The nominal capacity of the station at present is 27,000 k.w.; when the new unit is in operation it will be 34,500 k.w. The tenders for the new unit close on May 29, and the machinery is to be delivered by March 1, 1929. Under the new scheme of numbering the generating units, tunnels, and pipe-lines at the power station, the generating unit last to he added will be No. 1. Tenders have been called for the necessary pipeline and close on May 29. For some months the average inflow from the Harper River has been very little, amounting only to the equivalent of a. trickle. This has been due to the fact that a new outlet weir is under construction and repairs to the intake gates are in hand. The new weir is of a special type; with an adjustable gate 15 feet wide. By using this .gate it will be possible, when necessary, to raise the normal level of the lake, which is 1670 feet, to 1672 feet. The work of constructing this new weir, which is downstream from .the old one, will be completed, it is anticipated, about the end of February. The repairs to the intake gates wall be effected, circumstances permitting, in a fortnight or three weeks.
