power, whereas your price is ' near £3. This shows so large a discrepancy that it is difficult to make up by any diversity factor ' such as you have. Even if you take a factor of 3 such as you may have your price should be ' say £16 plus 60 per cent for your costs and profit £25. Dividing this by your diversity factor, 3, ■ we have £8 10s 8d per k.w. as a proper price, giving an income of £145 per year for your 17 k.w. each. As I pointed out, your plant capital cost per K.W. installed, of £200 per K.W. is very high, and your prices on the other hand are excessively low. In view of this it would be well to revise your whole system of accounts. As a municipal supply is in essence a monopoly, it is of first , importance to give a good and adequate service- to all appli-$p cants and to receive from these -'*] applicants a return sufficient to meet all possible costs. I understand that the Govern- $. ment have made an offer to you to supply you with alternating current. Your system is direct . current, and the alternating system is becoming universal in New Zealand as well as else- 4 where.

But what I wish to impress upon you is that the man who uses capacity of your plant at peak times must pay for it. / I was pleased to find that your Electrical Engineer had made it /*.-is easily posible for you to dis-: M tinguish between a _ heating and ?M ironing , load and a lighting load,';'% by his method of different $§ voltages, and- his proposal for a two-way switch will solve the |§ difficulty. It would be advis- "i able for you to pass a by-law in addition that consumers are not to use their irons during lighting peak load hours. Also some consideration should be made to consumers who install a great many lamps and - only use half or quai-ter of them ~. during peak load hours.
