     Excerpt of a letter dated 20 Mar 2000 by Mr Wong Fook Hung, Managing Director Power Supply Ltd, to The Straits Times Forum Page.

Power Supply is the public electricity supplier as well as a billing and collection agent.

Apart from charges for electricity, water and gas, Power Supply also bills and collects the water-conservation tax, waterborne fee, sanitary-appliance fees and refuse-collection fees.

The water-conservation tax is meant to discourage wastage and drive home the point that water is a precious and strategic resource in Singapore.

For households, it is tiered at different tax rates according to volume of usage. The waterborne fee is for treatment of waste water and is charged on the volume of water used. The utilities deposit is required as a security against non-payment and is equal to 1 times the average monthly bill or one month's bill for domestic customers on GIRO.

Instead of deposits, some service providers collect advance payments to mitigate the risk of non-payment. The deposit collected by Power Supply is on behalf of three utility service providers, namely PUB, PowerGas and itself. All three parties need to incur costs in advance to produce or purchase the supply before customers are even billed and payments collected for the utilities consumed by them. An example is payments for daily purchases from the Singapore Electricity Pool which are made nine days after each purchase. On the other hand, customers are billed monthly for utilities already consumed and payments are due only two weeks after billing.

Power Supply's electricity business is regulated. Its earnings are determined through a formula based on its operating costs. If Power Supply were to pay interest on deposits, then the interest paid plus administrative costs would increase the operating expenditure. This would add costs and customers would not have any real benefit as it would result in higher tariffs.
