Report by PREECE, CARDEW & RIDER on the Rehabilitation of Plant to be Operated by The Hongkong Electric Co., Ltd.
on Behalf of The Civil Administration.
SCOPE. This Report is related to the verbal terms of reference as discussed between Col. Thomson and Mr. Follows of The Civil Administration and Mr. Jackson of Messrs. Preece, Cardew & Rider on November 23rd & 24th which are set out in detail in the attached covering letter, and except where expressly stated to the contrary it is agreed that the plant shall be repaired and maintained in accordance with paragraph 5 thereof.

A scrutiny of the pre-war records shows that the Day load was approximately 12,000 kilowatts and the Peak load at night 20,000 kilowatts.
The present Day & Night loads are 4,000 and 6,000 K.W. respectively.
The estimated loads by next March are 6,000 & 10,000 K.W. respectively.
It will be observed that the ratio between Day & Night load in each instance is approximately the same; this is entirely fortuitous. Assuming the present rate of expansion of load is maintained it will be necessary to meet Peak loads of 10,000 kilowatts before the end of February and it is to this basis that the following observations are related. The present rate of expansion is however limited not only by the staff available to make reconnections but by the deliverate policy of the Company not to provide domestic power until such times certain existing plant has been overhauled and reconditioned and is fit for commercial operation.

To meet the demand envisaged it is essential that Turbines Nos.7, 4, 3 & 2 and Boilers Nos.14, 13, 11, 4 & 3 shall be in reasonable commercial condition together with the associated ancilliary plant, switchgear, cables &c.

TURBINES.
>
Nos.8 Turbo Alternator Set. This Set has apparently been misused by the Japanese but as it cannot be used to meet the load envisaged the cost of reconditioning does not come within the terms of reference.
No. 7 Turbine. Owing to operating conditions it is not practicable to make a detailed inspection of Number 7 Turbine but so far as can be ascertained this machine appears to be in a reasonable commercial condition and there is no reason to anticipate trouble. Only normal running spares should be required.
No. 4 Turbine. This machine has been opened up for examination which reveals the fact that the Turbine shaft is considerably out of true. Attempts are being made to rectify
In the event of this which may or may not be successful. their being successful, it is fair that the condenser should be brought up to a reasonable state of repairs which will involve the provision of 20% of the tubes and 50% of the ferrules, the cost to be divided equally between the Company In the event of the attempts and the Civil Administration.
to straighten the Turbine shaft proving unsuccessful there is no point in reconditioning the condenser in which case the Set will not come within the terms of reference.
